Note: Throughout this document, “Avid MediaCentral Platform Services” will be referred to as “MCS”. “Red Hat Enterprise Linux” will be referred to as “RHEL”. Note: The RHEL deployment used in an MCS environment is a command-line based operating system. The installation process will require the editing of various system files. Although multiple text editors exist, the tool used throughout this document is “vi”. If needed, a short introduction to vi is included in the MediaCentral Platform Services Concepts and Clustering Guide. Note: When working in Linux, this guide assumes the user is logged in as the “root” user. Perform all commands and server configuration as the “root” user.

REREQUISITES 10 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to guide the preparation of all materials needed for the MCS installation and to pre-configure all connected systems for integration with MCS. The following table describes the topics covered in this chapter. Step Task Time Est. 1 Before You Begin varies A quick check to make sure you have everything in place for an efficient and successful installation. 2 Network Interface Cards and Network Connections 15 min Network connection information for various deployment options. 3 Accessing the MCS Server(s) 1 min Understanding how to connect to the MCS server(s). 4 Obtaining the Software varies Where to find all the software necessary for the installation. 5 Updating MediaCentral UX Licenses 15 min Licensing requirements for Interplay Production and iNEWS. 6 Creating User Accounts 10 min Convers the creation of user accounts required by MCS. 7 Adjusting Interplay Production Settings 5 min Information on adjusting settings required by MCS. 8 Adding the MediaCentral UX Version to Avid iNEWS 5 min Enables MediaCentral UX user to connect to iNEWS. 9 Installing the MediaCentral Distribution Service 10 min Required for certain Interplay Production workflows. 10 Creating the MCS Installation USB Drive 45 min In this procedure, you create the USB drive you will use to install the MCS software. 11 MCS 2.3 Installation and Configuration Guide Before You Begin A successful MCS installation begins with careful planning. Ensuring that you have identified all prerequisites to the installation is very important. Examples: Networking: IP addresses, hostnames, domain name, DNS, NTP, SNMP, etc. Cluster-specific information: Additional IP addresses, e-mail address Users: Identifying users, user groups, and passwords (both local and domain users) Host Solutions: Identify what systems will connect to MCS. Once identified, it is also important to verify that these systems are available and operating normally. Examples: o Avid | ISIS o Avid | iNEWS o Interplay | Production o Interplay | MAM o Media Composer | Cloud For Interplay | Production deployments, the following systems could also be required: o Interplay | Production Services Automation and Interplay | Consolidate (Required for certain Interplay | Delivery workflows. Media | Index is required for this functionality.) o Interplay | Transcode (Required for Send To Playback workflows) o Interplay | STP Encode (Required for Send To Playback of Long GOP media formats) o Interplay | Transfer (Required for Send To Playback to 3 party playback solutions) rd To assist in ensuring you have all the information you need prior to beginning the installation, Avid provides a “Pre-Flight Checklist” available on the MediaCentral Services page of the Avid Knowledge Base. Completing the Pre-Flight information will avoid delays during the installation process. While the installation procedures for MediaCentral UX, Media Composer Cloud and Interplay MAM are very similar, the configuration steps are different. Any configuration differences between MediaCentral UX and Media Composer Cloud will be identified in this document. For differences in the Interplay MAM configuration process, refer to the Interplay | MAM Installation Manual. MCS is available in single server and cluster configurations. A cluster is a group of MCS servers that provide redundancy, load balancing, and scale. Each server in a cluster is called a “node”. During the cluster configuration, one server is identified as the Master node. If you have multiple MCS servers in a rack, the Master node is usually the top-most server in the rack. If you are configuring a cluster, configure Part I through Part III concurrently on all cluster nodes. Part IV of this installation document must be completed on the Master node only, unless otherwise instructed. 12 MCS 2.3 Installation and Configuration Guide Network Interface Cards and Network Connections Avid supports the onboard 1 Gb NIC for each of the HP DL360 Gen8 / Gen9 and Dell R620/R630 servers. However, certain workflows require the increased bandwidth of an add-in 10 Gb card. For example, a 10 Gb connection is required for any MCS deployment that will use 100+ Mbps video formats (e.g., AVC-I 100, DVCPro 100, DNxHD 145). 10 Gb connections may be desired for additional bandwidth / playback streams. The HP DL360p Gen8 supports additional 1 Gb network adapters. See HP DL360p Gen8 Card Placement in Appendix A for more information. For more information on determining 1 Gb or 10 Gb connections as well as information on supported adapters, see the MediaCentral Platform Services Hardware Guide located on the MediaCentral Services page of the Avid Knowledge Base. The Zone in which the network connection is made must also be considered. Zone 1: Connected to ISIS VLAN(s) through an ISS 1 Gb or 10 Gb port (direct connect) Zone 2: Connected to ISIS VLAN(s) through a 1 Gb or 10 Gb port on an Avid qualified layer-2 switch (non-routed) Zone 3: Connected to an Avid qualified layer-3 switch (routed) with known Quality of Service (QoS); traffic routed to ISIS (one hop) and (if applicable) load-balanced across ISIS VLANs (approximately a 60/40 ratio) For more information on networking in an Avid environment, see “Network Requirements for ISIS and Interplay PAM and MAM” located at: http://avid.force.com/pkb/articles/en_US/compatibility/en244197 MediaCentral UX and Media Composer Cloud In this workflow MCS decodes the source media format on ISIS and streams images and sound to the clients. This workflow requires MCS to connect to an Avid ISIS system. Zone 1, Zone 2 or Zone 3 (recommended) connections are supported. Interplay MAM In this workflow MCS provides playback of video assets registered as browse proxies by Interplay MAM. The connection required depends on where the browse proxies are stored. For non-ISIS storage, the network connection is at the user’s discretion as long as it is a 1 Gb connection or better. For ISIS storage, Zone 1, Zone 2 or Zone 3 (recommended) connections are supported. Avid iNEWS iNEWS-only deployments do not require an ISIS connection. The network connection is at the user’s discretion as long as it is a 1 Gb connection or better. 13 MCS 2.3 Installation and Configuration Guide Accessing the MCS Server(s) The initial configuration of the MCS server(s) must be completed using a directly connected monitor and keyboard to the server, or through a KVM (keyboard, video and mouse) device. Note: Some KVMs present virtual USB devices to the operating system. These devices might be assigned a device name (sda, sdb) by RHEL during the installation, which results in a failed installation. Disable this option on your KVM if applicable. Once the initial configuration is complete, Avid recommends connecting to MCS indirectly through SSH (Secure Shell). SSH is preferable for the following reasons: Allows for an expandable view of the RHEL interface (adjustable window size) Allows for multiple sessions to the host server or to multiple servers Allows for simplified copy/paste of commands between SSH windows Allows for logging of all session output On Windows, PuTTY.exe is an example of a SSH client: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html At the appropriate point in the installation procedure, you will be given the option to switch from a direct connection to an indirect connection. Copying Software to the MCS Server At various times during the upgrade, you will need to copy software to the MCS server. This task can be performed using one of two methods: Using a Windows system and a SFTP tool such as WinSCP Connecting a USB drive directly to the server While the SFTP method may be preferred for ease of access, the USB method may be required for some operations such as backing up MCS files during a system upgrade. See Copying Software to the MCS Server in Appendix A for details on each of these methods. 14 MCS 2.3 Installation and Configuration Guide Obtaining the Software Multiple software packages are required to properly install and configure MCS. These include: Red Hat Enterprise Linux (RHEL) RHEL Security Updates MCS Installation Packages MediaCentral Platform Services (if applicable) MediaCentral Platform Services Updates (if applicable) MediaCentral UX Closed Captioning Service (if applicable) MediaCentral Distribution Service (MCDS) (if applicable) Interplay MAM Connector (If applicable) Media Composer Cloud plugin (If applicable) Media Distribute (if applicable) Storage Controller Driver ISO for the HP ProLiant Gen9 Server (If applicable) GlusterFS Red Hat Enterprise Linux (RHEL) Due to licensing restrictions, Avid is unable to redistribute the RHEL installation media.

See the Media Composer | Cloud Installation and Configuration Guide for additional details. 23 MCS 2.3 Installation and Configuration Guide 6. From the main menu, select Site Settings>Interplay Transfer Settings. MediaCentral will poll this setting for configured Transfer Engines and AirSpeed servers when creating STP profiles. 7. Click Apply. Adding the MediaCentral UX Version to Avid iNEWS Before connecting MediaCentral UX to iNEWS, the MediaCentral UX Client version must be added to the iNEWS SYSTEM.CLIENT.VERSIONS file. Refer to the Avid MediaCentral Platform Services ReadMe for the correct version number for your installation. See Appendix D: Configuring iNEWS for Integration with MediaCentral for instructions on adding the version number to iNEWS. 24 MCS 2.3 Installation and Configuration Guide Installing the MediaCentral Distribution Service The MediaCentral Distribution Service (MCDS) is a lightweight required for Send to Playback (STP) operations. It analyzes the STP request and determines if additional actions are required before sending the media to the playback device (AirSpeed, Transfer Engine, other). An Interplay Transcode provider is required for STP operations requiring audio mixdowns (stereo audio tracks) or video mixdowns (sequences with dissolves). An Interplay STP Encode provider is required when using Long GOP media. MCDS is not used if you are sending an asset directly to Transcode or Delivery. MCDS is not used in iNEWS-only configurations. The following guidelines apply to installing MCDS: Supported on Windows 7 64-bit and Windows Server 2012. o If you are running Windows Server 2012, you must install the Windows Desktop Experience feature. For more information and installation procedures, see the Interplay | Production Dell and HP Server Support guide at: http://avid.force.com/pkb/articles/en_US/readme/Avid-Interplay-Production-V3-3-xDocumentation o If you are running Windows 7 N, Windows Media Player must be manually installed. For more information on “N” versions of Windows, see: http://windows.microsoft.com/en-us/windows7/products/what-is-windows-7-n-edition Requires a minimum of 512MB of RAM and approximately 380MB of hard drive space on the host server. Ensure that all enabled network adapters on both the system hosting the MCDS and the Interplay Production Services Engine are fully routable to each other. Can be installed on a server hosting other services or applications, such as the Interplay Production Services Engine or an Interplay Archive Provider. Must be installed on a system that has the ISIS Client software installed. Must not be installed on a system running Interplay Transcode or STP Encode. These systems share libraries with MCDS and a co-install risks introducing incompatibilities. Must not be installed on an Interplay Production Engine or Interplay Archive Engine. As of Interplay Production 3.2, MCDS should not be installed on a Media Indexer server as the two systems risk sharing network port 8443. In MediaCentral UX 1.x, the MCDS service used port 8080 for normal http communication. In MediaCentral UX v2.0 / MCDS v3.1, the port changed to 8890. This change allows MCDS to be installed on the same server as the Production Services Engine (if desired). Port 8443 is used for http security protocol. Versions of MCDS prior to v3.3 required the Interplay Service Framework (32 or 64bit) software to be installed on the system hosting MCDS. As of v3.3, this is no longer a requirement. For redundancy purposes, MCDS can be installed on two systems. Installing a second instance of MCDS does not provide load-balancing functionality. You will configure MediaCentral UX to find the installed instance(s) of MCDS later in this document. Installing the MediaCentral Distribution Service: 1. Launch the MCDS installer on your desired system(s). 25 MCS 2.3 Installation and Configuration Guide 2. Proceed through the installation and accept the defaults. You may be asked to install prerequisite requirements such as Microsoft Visual C++. 3. Once installed, use Windows Computer Management to verify that the service is “Started” and the Startup Type is configured as “Automatic”. Creating the MCS Installation USB Drive The MCS installation is initiated from a bootable USB drive that contains the OS (Red Hat Enterprise Linux) and the MCS software. For this procedure you require the following items: A Windows-based computer The MCS installation package RHEL installation image (.iso) file A 16GB or larger USB drive Note: Avid has been informed of problems using USB drives from some vendors. If the server does not boot from the USB drive, or fails to complete the boot, try using a drive from another vendor or a drive with a larger capacity (32GB). This procedure uses an application called “ISO to USB” to create a bootable USB drive containing the required RHEL operating system and MCS files. Do not simply drag and drop installation files onto the USB drive as this will not create the correct file structure needed to successfully install MCS. Note: Since “ISO to USB” creates a bootable drive, Avid recommends only connecting the USB drive you plan to use to the Windows system. If you have more than one USB drive inserted, make sure you choose the right one when performing this procedure. Preparing the Installation Drive for the HP ProLiant Gen9 The procedure for creating the MCS installation drive on a ProLiant Gen9 server differs from that of other installations. Make sure you follow the customized instructions for your server type. This section contains three procedures: Preparing the MCS Installation USB Drive Copying the Storage Controller Driver to the USB Drive Preparing the MCS Installation USB Drive: 1. Log into a Windows system. 2. Connect the USB drive to the Windows system and give it a few moments to be recognized. 3. Use Windows Disk Management to format the USB drive as a FAT32 volume. 26 MCS 2.3 Installation and Configuration Guide 4. Extract the contents of the MediaCentral_Services__Linux.zip file to the desktop (or your preferred destination directory). 5. Open the newly created MediaCentral_Services_ _Linux folder. 6. Double-click iso2usb.exe to launch the application. 7. Choose the Diskimage radio button then navigate to the RHEL image (.iso) file (named rhel-server-6.5-x86_64-dvd.iso or similar). Note: Make sure the RHEL image (.iso) file is accessible locally (preferable) or over the network from your computer. 8. In the “Additional Files” field, navigate to the MediaCentral_Services_ _Linux folder and click the “Select Folder” button. 9. Use the table below to verify that the Hard Disk Name and USB Device Name fields are correct for your deployment. RAID Configuration RAID 1 (“Hard Disk Name”) RAID 5 USB (“USB Device Name”) RAID 1 and RAID 5 sda sdb sdc RAID 1 only sda -- sdb For example, for a system deploying both RAID 1 and RAID 5 volumes, enter the following values in the dialog: • Hard Disk Name: sda • USB Device Name: sdc Important: For those familiar with earlier HP servers, the HP ProLiant Gen9 server identifies the RAID 1, RAID 5, and the USB drive with different device names. 27 MCS 2.3 Installation and Configuration Guide 10. Verify the USB Drive letter or use the pull-down menu to select a new drive letter. 11. Click OK in the main dialog. 12. A process begins to copy the RHEL image (.iso) file and the MCS installation files to the USB drive. This process takes 10-20 minutes. Once complete, the USB drive has everything it needs to complete the RHEL and MCS installation. Note: Copying the RHEL image (.iso) file to the USB drive is a one-time process. To install MCS on more than one server, or to re-install MCS, you do not need to repeat these steps. 13. Click Exit to close the application. Copying the Storage Controller Driver to the USB Drive: 1. With the Installation USB drive still plugged in to the Windows laptop or desktop, copy the RAID controller driver ISO to the root directory on the drive: dd-hpsa-18216-x86_64.iso 2. Rename the ISO: • Old Name: dd-hpsa-18216-x86_64.iso • New Name: z_dd-hpsa-18216-x86_64.iso Renaming the driver ISO is essential, since the installation script attempts to mount the first ISO it finds as the RHEL ISO. If you do not rename it, the installation will fail. 28 MCS 2.3 Installation and Configuration Guide Preparing the Installation Drive for HP Gen8 and Dell Servers Follow this procedure only if you are installing MCS software components on supported HP Gen8 or Dell servers. Preparing the MCS Installation USB Drive: 1. Log into a Windows system. 2. Connect the USB drive to the Windows system and give it a few moments to be recognized. 3. Use Windows Disk Management to format the USB drive as a FAT32 volume. 4. Extract the contents of the MediaCentral_Services_ _Linux.zip file to the desktop (or your preferred destination directory). 5. Open the newly created MediaCentral_Services_ _Linux folder. 6. Double-click iso2usb.exe to launch the application. 7. Choose the Diskimage radio button then navigate to the RHEL image (.iso) file (named rhel-server-6.5-x86_64-dvd.iso or similar). Note: Make sure the RHEL image (.iso) file is accessible locally (preferable) or over the network from your computer. 8. In the “Additional Files” field navigate to the MediaCentral_Services_ _Linux folder and click the “Select Folder” button. 29 MCS 2.3 Installation and Configuration Guide 9. Verify the Hard Disk Name and USB Device Name fields are as follows: • Hard Disk Name: sdb • USB Device Name: sda Note: If the drive names are not configured properly in the kickstart file, you could encounter errors in the deployment process. Example: “Error Partitioning: Could not allocate requested partitions: not enough free space on disks.” 10. Verify the USB Drive letter or use the pull-down menu to select a new drive letter 11. Click OK in the main dialog. 12. A process begins to copy the RHEL image (.iso) file and the MCS installation files to the USB drive. This process takes 10-20 minutes. Once complete, the USB drive has everything it needs to complete the RHEL and MCS installation. Note: Copying the RHEL image (.iso) file to the USB drive is a one-time process. To install MCS on more than one server, or to re-install MCS, you do not need to repeat these steps. 30 MCS 2.3 Installation and Configuration Guide PART II: BIOS & RAID C ONFIGURATION 31 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to prepare the server hardware for the installation of RHEL and MCS.

The device can be re-enabled once you have completed the MCS installation. Proceed to Configuring the Onboard RAID on page 41. 40 MCS 2.3 Installation and Configuration Guide Configuring the Onboard RAID This section provides information on the RAID configuration for the following Avid qualified servers: • HP ProLiant DL360 Gen9 RAID Configuration • HP ProLiant DL360p Gen8 RAID Configuration • Dell PowerEdge R620 / R630 RAID Configuration RAID 1: All MCS implementations require a RAID 1 (mirror) for the system (OS) drive. This RAID provides redundancy in the event of HD failure. RAID 5: Certain deployments also require additional disks configured as a RAID 5 (data striping with parity blocks) for caching file data. This RAID provides redundancy and increased performance. See the MediaCentral Platform Services Concepts and Clustering Guide for more information on RAID configurations. HP ProLiant DL360 Gen9 RAID Configuration In this step you configure two of the HD drives in the server enclosure as a RAID Level 1 – a mirrored RAID – where the RHEL and MCS software will be installed. This is done using the Option ROM Configuration for Arrays utility, in the HP server’s BIOS. If applicable, configure the remaining HD drives in the server enclosure as a RAID Level 5. In a RAID 5 data is automatically distributed across all the disks in the RAID for increased performance and redundancy. This is done using the Option ROM Configuration for Arrays utility, in the HP server’s BIOS. Note: If the list of available disks does not appear as expected, it may be that a RAID has already been created. Deleting a RAID destroys all the data it contains, so verify it is safe to do so first. Note: This document provides instructions for creating a media cache volume as a RAID 5 using multiple disks in the server enclosure. However, other configurations are possible, including two drives in a RAID 1 configuration, or a single drive. For details, see the MediaCentral Platform Services Hardware Guide. 41 MCS 2.3 Installation and Configuration Guide Configuring the HP ProLiant DL360 Gen9 RAID 1 Note: The RAID configuration process will immediately transition into the Red Hat / MCS installation.

In this step you verify the RAID configuration through the BIOS. Later you will use RHEL to ensure the RAID arrays are cleared of existing data. Two of the HD drives in the server are configured as a RAID Level 1 – a mirrored RAID – where the RHEL and MCS software will be installed. If applicable, the remaining drives in the server enclosure will be configured as a RAID Level 5. In a RAID 5 data is automatically distributed across all the disks in the RAID for increased performance and redundancy. Note: This document provides instructions for creating a media cache volume as a RAID 5 using multiple disks in the server enclosure. However, other configurations are possible, including two drives in a RAID 1 configuration, or a single drive. For details, see the “MediaCentral Platform Services Hardware Guide”. Verifying the PowerEdge Dell R620 / 630 RAID Configuration: Note: The RAID configuration process will immediately transition into the Red Hat / MCS installation.

Caution: If you are in the process of upgrading from an earlier version of MCS — called ICS in earlier releases — it is a fresh install, and will overwrite your current ICS settings and databases. Before proceeding with the upgrade, back up your current settings: Database: The ICS settings and database using the backup script (system-backup.sh) provided. See Backing up the MCS System Settings on page 141. SSL Private Key(s): If you deployment makes use of CA-signed certificates, back up private(s), regardless of the upgrade path. Corosync Configuration File: If you configured ICS 1.4.x for unicast, you made changes to the corosync configuration (corosync.conf) file. The installation script overwrites this file. To preserve your changes, back up the file before beginning the upgrade, and restore it after. Note: For workflow details on upgrading to MCS 2.3 from an earlier release, see the MCS 2.3 Upgrading Guide, available from the Avid Knowledge Base MCS 2.3 web page. How to proceed: If you are installing MCS on a Dell server, additional steps are required during the server imaging process. Proceed to Special Instructions for Dell Servers on page 56 (the next page). If you are installing MCS on an HP server, proceed directly to MCS Software Deployment on page 60. 55 MCS 2.3 Installation and Configuration Guide Special Instructions for Dell Servers Dell servers are generally shipped with preconfigured RAID 1 and RAID 5 arrays. These RAID sets include partitions that can interfere with the kickstart assisted software deployment. The partitions must be deleted prior to starting the installation. Deleting and recreating the RAID sets using the DELL BIOS utility does not erase data, nor does it delete existing partitions. That is, deleting a RAID does not delete the partition table — unless you initialize the disk at the same time. However, initializing the disk is a slow process. In this procedure, you boot from the MCS Installation USB Drive and launch a RHEL “rescue” session in order to examine the current system partitions and delete them. If you are installing MCS on an HP server, proceed to MCS Software Deployment on page 60. 1. Boot from the MCS Installation USB drive. 2. At the RHEL Welcome screen, select “Rescue Installed System”. 3. When prompted choose the language and keyboard. 4. Choose “Hard drive” as the rescue method. For the purposes of booting from a RHEL image, the USB drive is considered a hard drive. 56 MCS 2.3 Installation and Configuration Guide 5. Select the “/dev/sda1” partition (the USB drive). Leave the “Directory holding image” field blank. 6. Select No in the Setup Networking window; as networking is not needed at this time. 7. Select “Skip” in the Rescue window. 57 MCS 2.3 Installation and Configuration Guide 8. At the next screen, choose “shell Start shell” and select Ok. 9. At the system prompt, use the RHEL fdisk utility to examine the current partitions: fdisk -cul This command will display the available disks and partitions on the system. Use Shift-Pg Up and Shift-Pg Down to view the entire output, since scroll bars will not be present in the rescue shell. In this case “sda” should be the USB boot drive, “sdb” should be the RAID 1 volume and “sdc” should be the RAID 5 volume. The following example shows information for “sdb” with three partitions (sdb1, sdb2, sdb3): Disk /dev/sdb: 500.1 GB, 500074307584 bytes 255 heads, 63 sectors/track, 60797 cylinders, total 97670732 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc755f5b0 Device Boot /dev/sdb1 * /dev/sdb2 /dev/sdb3 Start 2048 1026048 42051584 End 1026047 42051583 976707583 Blocks 512000 20512768 467328000 Id 83 8e 8e System Linux Linux LVM Linux LVM Additional entries for the filesystem (sdb4, sdb5) could be possible. Example: Disk /dev/sdb: 598.9 GB, 598879502336 bytes 255 heads, 63 sectors/track, 72809 cylinders, total 11696828 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x930a8a0e Device Boot /dev/sdb1 * /dev/sdb2 /dev/sdb3 /dev/sdb4 /dev/sdb5 Start 2048 1026048 2050048 43075584 43077632 End 1026047 2050047 43075583 1169686527 1169686527 Blocks 512000 512000 20512768 563305472 563304448 Id 83 83 8e 5 8e System Linux Linux Linux LVM Extended Linux LVM 58 MCS 2.3 Installation and Configuration Guide You will need to delete the any partitions on the RAID 1 volume and the RAID 5 volume (if applicable). This process will assume “sdb” is the RAID 1 and “sdc” is the RAID 5. 10. Use the RHEL fdisk utility to select the sdb volume: fdisk /dev/sdb 11. Type: p to print the current filesystem partition table. This will show you a similar output as the fdisk –cul command you used earlier. 12. Type: d to begin deleting the partitions. 13. You will be prompted to specify the partition to delete. Example: 1 Partition number (1-4): 1 14. Repeat the above two steps to delete the remaining “sdb” partitions. 15. Once complete, type p to print the partition table again. An empty partition table should look like the following: Device Boot Start End Blocks Id System 16. Type: w to write the changes to the partition table and exit the utility. 17. If you have a RAID 5 volume, repeat this process by specifying the RAID 5 “sdc” partition: fdisk /dev/sdc 18. Repeat the above steps and type w to write the changes to the partition table and exit the utility. 19. Verify that the partitions on sdb and sdc (if applicable) were successfully removed using the RHEL fdisk utility: fdisk -cul 20. Reboot the server by selecting CTRL-ALT-DEL. You will again boot from the USB Installation drive. The correct partitions and filesystems will be created automatically during the installation. Proceed to MCS Software Deployment on page 60. 59 MCS 2.3 Installation and Configuration Guide MCS Software Deployment This process will install both RHEL and MCS from the MCS Installation USB drive. 1. Ensure the MCS Installation USB drive is connected to the server and reboot if necessary Note: For HP installs, an error message may appear: "[Firmware Bug]: the BIOS has corrupted hw-PMU resources". This error can be ignored. For more information, see: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03265132. 2. Wait for the RHEL Welcome screen to appear. Note: It has been reported that under some circumstances the installation bypasses the RHEL Welcome screen. This will not affect the install process. The correct installation choice is always selected by default. 3. If you are installing on an HP ProLiant Gen9 server, install the RHEL driver to enable RHEL support for the storage controller before proceeding: a. Press the Esc key to open the RHEL boot shell. b. At the boot shell, type the following: linux dd c. In the dialog that appears, confirm that you have a driver disk. 60 MCS 2.3 Installation and Configuration Guide d. The installer may prompt you to specify the location of the update. Select the device name indicating the MCS Installation USB drive (e.g sda). Similarly specify the partition on the device (e.g. sda1). e. Select the driver and select OK: z_dd-hpsa-18216-x86_64.iso f. When prompted for more drivers, select No. The driver is updated, and the installation process continues as described below. 4. Select “Install Red Hat with ICS” to install a new MCS and press Enter. Note: If you are upgrading your system, do not use the “Upgrade” option. For upgrading instructions, see the ”MCS 2.3 Upgrading Guide”. The RHEL and MCS packages are installed—this takes about 20 minutes. Note: Regarding the following error message: Unable to download kickstart file If you see this message, it could indicate that the partition where the installation program expects to find the kickstart file (sda) is already in use. The most likely cause is a KVM with “virtual media” capability reserving the sda partition to facilitate the mapping of removable drives to the attached server. To resolve the issue, disable the virtual media capability. Alternately, unplug the KVM and connect to the server directly using an external monitor and USB keyboard. 5. If you just created the RAIDs a warning screen appears indicating a device (i.e. the RAIDs) needs to be reinitialized. This is normal. Select Re-Initialize All. 61 MCS 2.3 Installation and Configuration Guide 6. The RHEL installation proceeds. When you see the “Post-Installation” message, it indicates the MCS installation scripts are being executed. 7. When the installation process is complete, you are prompted to reboot. DO NOT REBOOT before removing the MCS Installation USB drive. If you reboot without removing the USB drive the server will reboot from the USB drive again and re-launch the installer. Note: If you pressed Enter by mistake, remove the USB drive as quickly as possible (before the system boots up again). If this is not possible, you need to perform the installation again. 8. Once the MCS Installation USB drive is removed, press Enter to reboot the server. 62 MCS 2.3 Installation and Configuration Guide Booting RHEL for the First Time Like many operating systems, when you boot RHEL for the first time, you will be asked to provide some basic information. A RHEL “first boot” causes the RHEL Configuration screen to appear, providing access to system set-up menus. Note: The first boot set-up menu can be accessed at any time by typing “setup” (without quotes) at the Linux command prompt. Note: Some MCS software components depend on the language for RHEL being set to English. This is done automatically by the MCS installation scripts. Do not change the input language afterwards. Booting from the System Drive 1. From the Choose a Tool menu, arrow down to select “Keyboard Configuration” and press Enter. 2. In the Keyboard Selection menu, use the arrows to select the appropriate language for your keyboard. Note: Selecting a language for the keyboard is different from the language selected for RHEL. While selecting a different language for the keyboard is supported, the RHEL language must remain as English. 3. Press the Tab key to focus on the OK button and press Enter. 4. Press the Tab key to focus on the Quit button and press Enter. The first boot set-up menu can be accessed at any time by typing “setup” (without quotes) at the Linux command prompt. 63 MCS 2.3 Installation and Configuration Guide Changing the root Password The RHEL installation script configures a default password for the root user (the Linux user with administrator privileges). For security reasons, it is strongly suggested that you change the password for the root user at the earliest opportunity. To change the root password: 1. Log in a the Linux prompt Default user name: root Default password: _ Note: Please contact your Avid representative for the default root password. 2. While logged in as the root user type the Linux change password command: passwd 3. Follow the prompts to change the password. If you do not enter a strong password, RedHat will warn you that the password is bad. This could be because you have entered a password based on a word in the dictionary. While this warning can be ignored, Avid suggests using strong passwords. 64 MCS 2.3 Installation and Configuration Guide Network Configuration MCS servers support both static and dynamic (DHCP) IP addressing. Static addressing is the Avid recommended method for any MCS server and is a requirement for any MCS cluster deployment. Normally, on a server with multiple network interfaces (i.e. Ethernet connectors), each interface has its own IP address. However, MCS servers in Interplay MAM can benefit from port bonding (a.k.a. teaming), in which several network interfaces appear as a single IP address. Port bonding is supported in MCS for MAM deployments only. For more information, see Appendix B: Configuring Port Bonding for Interplay MAM. Under the Linux operating system, every physical network connector, called an interface in Linux, has a name. By default, when installing RHEL, the installer scans the NIC cards in the machine and labels the interfaces it finds, in the order it finds them. HP Servers: Each interface in an HP server is labeled “ethx”, where ‘x’ is an incremental number starting with zero. Example: eth0, eth1, eth2 and so on. This naming convention is true for both onboard and add-in (PCIe) network adapters. Dell Onboard: The Dell onboard interfaces are similar to the HP in that each interface is labeled as “emx”, where ‘x’ is an incremental number starting with one. Example: em1, em2, em3 and so on. This naming convention only applies to the onboard 1 Gb interfaces. Dell PCIe Slots: The PCIe slots in a Dell are labeled as “p1p1” (slot 1) and “p2p1” (slot 2). If you are using a 10 Gb network adapter in the Dell, it will be assigned one of these labels; depending upon where you added the card (either slot is acceptable). Note: This installation guide will use “eth0 as the default example for many commands. If you are using a Dell server, make sure to substitute “eth0”with the correct interface name for your deployment. In general on a Dell, these should be “em1” or “p1p1”. Note: To obtain a list of the NICs installed in your system, enter the following in a Linux command prompt: lspci | grep net Verify DNS The Avid MCS implementation on RHEL is not configured to automatically register in DNS. Work with your onsite IT Department to manually enter each MCS server in both Forward and Reverse DNS. If you will be configuring an MCS cluster, the cluster’s virtual IP and hostname should also be entered in DNS. From a Windows system, the “nslookup” command can be used in a command prompt to check the DNS records directly. 65 MCS 2.3 Installation and Configuration Guide Identifying NIC Interfaces and Connecting the Network Cable RHEL provides a simple means for visually identifying the NIC ports on a server, whether they are active or not. The ethtool command can be used to cause ports to blink for a pre-determined amount of time. To visually identify a NIC Interface: 1. Use the Linux ethtool command, identify your primary network interface by causing it to blink for 60 seconds: ethtool --identify 60 Where is the name of the interface you want to identify. • For HP servers, this is: eth0 • For Dell servers using a 1 Gb connection, this is: em1 • For Dell servers using a 10 Gb connection, this is: p1p1 or p2p1 Example: ethtool -–identify eth0 60 Note the use of the double-dash in the identify command. In Linux, a single- or doubledash distinguishes options from arguments. A double-dash often precedes a word (i.e. human readable) option. 2. Connect your network cable at this time. a. If you are on a Dell server, connect your network cable to the interface that flashed for “em1”, “p1p1” or “p2p1”. Skip to Ensuring the NIC Interface Comes Up at System Startup on page 74. b. If you are on an HP server and will be connecting through a 1 Gb connection to a supported onboard NIC, connect your network cable to the interface that flashed for “eth0”. Skip to Ensuring the NIC Interface Comes Up at System Startup on page 74. c. If you are on an HP server and will be connecting through 10 Gb connection, connect the fibre cable to the PCIe card. Proceed to (HP Only) Verifying the NIC Interface Name on page 67. d. If you are on an HP server and will be connecting through a 1 Gb connection to an add-in 1 Gb NIC, “eth0” may or may not have flashed on that card. If the above command made “eth0” flash on the add-in card, connect your cable to the port that flashed. If the above command made “eth0” flash on the onboard adapter, connect the network cable to the first port (far left) of the add-in card and repeat the identify command to determine the name of the port you are connected to (you will need this information in the following step). Proceed to (HP Only) Verifying the NIC Interface Name on page 67. 3. If needed, repeat the above to identify additional ports. 66 MCS 2.3 Installation and Configuration Guide (HP Only) Verifying the NIC Interface Name In an HP server, Avid assumes that interface “eth0” will be used. Since all interfaces in an HP server are named “ethx”, additional steps need to be taken to ensure “eth0” is used. To verify the NIC interface name: 1. Enter the RHEL Configuration screens by typing the following at the command prompt: setup 2. From the Choose a Tool menu, select Network Configuration. Press Enter. 3. From the Network Configuration menu, select Device Configuration. Press Enter. A list of NIC cards contained in the server enclosure appears. 4. Make note of the name associated with your interface. If necessary, use the arrow keys to move up and down the list. In the above example, a 10 Gb card has been placed in the server. It is currently assigned “eth4”, but we will want to change that to “eth0”. 5. Note the name assigned to the interface of interest (e.g. eth0, eth1, ethn). 6. Perform the actions required at each menu (Cancel, Quit, Exit, etc.) to return to the Linux prompt. (HP Only) Swapping NIC Interface Names If your interface of interest was not already named “eth0”, you will need to rename it. You will also rename the NIC interface currently using the name “eth0”. 1. Edit the network script where persistent names are assigned to network interfaces: vi /etc/udev/rules.d/70-persistent-net.rules Note: A server with just one installed NIC card does not have a 70-persistent-net.rules file by default. If the file is missing for any reason, it can be created using the following command: udevadm trigger --subsystem-match=net The output may look similar to the following. Note that in the example below, the 10Gb Myricom card has been assigned “eth4”. In this scenario, you will want to swap the names for “eth0” and “eth4” so that the desired Myricom board is renamed “eth0”. 67 MCS 2.3 Installation and Configuration Guide # PCI device 0x14e4:0x1657 (tg3) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="ac:16:2d:74:1b:58", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x14e4:0x1657 (tg3) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="ac:16:2d:74:1b:59", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" # PCI device 0x14e4:0x1657 (tg3) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="ac:16:2d:74:1b:5a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2" # PCI device 0x14e4:0x1657 (tg3) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="ac:16:2d:74:1b:5b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3" # PCI device 0x14c1:0x0008 (myri10ge) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:60:dd:45:14:50", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4" 2. Locate the lines corresponding to the NIC card you want to name eth0 and the one already using the name. Use the arrow keys on the keyboard to navigate the file. 3. Press the A key to append to the end of the line: NAME="eth0" 4. Change NAME="ethX" (e.g. eth1, eth2, etc.) to the following: NAME="eth0" 5. Locate the line corresponding to the NIC card that was already using the name eth0 and rename it: NAME="ethX" where “X” is the number you removed in step 5 (e.g. eth1, eth2, etc.); that is, swap the names. 6. Save and exit the vi session. Press and type: :wq 68 MCS 2.3 Installation and Configuration Guide (HP Only) Removing the MAC Address Hardware References In addition to renaming the NIC interface, you will also need to remove the hardware references – generally known as MAC addresses – from the affected NIC interface configuration files. For each card where you renamed a NIC interface, edit the corresponding interface configuration file and remove the hardware identifier. Otherwise, Linux will override the changes you made earlier and reassign the old interface names the next time it boots (or you restart the Linux network services). 1. Using the Linux text editor, vi, open the interface configuration file for one of the renamed interfaces (e.g. ifcfg-eth0): vi /etc/sysconfig/network-scripts/ifcfg-eth0 In Linux, each NIC interface has its own configuration file. 2. Locate the line containing the hardware identifier. It has the following form: HWADDR = 00:00:00:00:00:00 3. Position the cursor on the HWADDR line and press “dd” to remove it. That is tap the lower case letter D twice. 4. Save and exit the vi session. Press and type: :wq 5. Repeat the above steps for the other NIC interface you renamed (e.g. ethX). 6. Once you have finished removing the hardware references for both the renamed NIC interfaces, reboot the server to restart the network services and make the effects permanent: reboot The MAC addresses will refresh automatically after the reboot. 7. Once the system has rebooted, log back into RHEL. Note: Changing the contents of the /etc/udev/rules.d file requires a reboot rather than simply restarting network service. 69 MCS 2.3 Installation and Configuration Guide Configuring the Hostname and Static Network Route This process will assume the configuration of a static IP address is desired. 1. Enter the RHEL Configuration screens by typing the following at the command prompt: setup 2. From the Choose a Tool menu, select Network Configuration. Press Enter. 3. From the Network Configuration menu, select Device Configuration. Press Enter. A list of NIC cards contained in the server enclosure appears. 4. Use the arrow keys to locate the primary interface (eth0, em1 or p1p1). Press Enter to view its details. Note: If you configured port bonding for an Interplay MAM integration, your primary interface may be called “bond0”. For more information on port bonding, see Appendix B. 5. Dynamic Host Configuration Protocol (DHCP) is the default option. Arrow down to the “Use DHCP” line and press the spacebar to deselect it. 6. Enter the following information: Static IP address Netmask (Subnet) Note: All MCS servers in a cluster must be in the same subnet. Default gateway IP Primary DNS server Secondary DNS server (if applicable) 70 MCS 2.3 Installation and Configuration Guide 7. Arrow or Tab down to the OK button and press Enter. You are returned to the list of NIC cards in the enclosure. 8. Select Save and press Enter. 9. From the Choose a Tool menu, select DNS Configuration. Press Enter. 10. Enter the following information for the DNS Configuration: Enter the hostname This should be entered as the short hostname only (e.g. wavd-mcs01) and not the fully qualified domain name (FQDN) (e.g. wavd-mcs01-wavd.com). Note: Hostnames should comply with “RFC 952” standards. Hostnames can be up to 24 characters, but Avid recommends keeping it under 15 characters. Hostnames can contain numbers, but never begin a hostname with a number. The only “special character” allowed in a hostname is a dash “ - “. Underscores are not allowed. Primary DNS server Secondary DNS server (if applicable) Tertiary DNS server (if applicable) DNS search path 11. Select Save & Quit. Press Enter. 12. Select Quit. Press Enter. 71 MCS 2.3 Installation and Configuration Guide Verifying the hosts File Contents The hosts file is used by the operating system to map hostnames to IP addresses. It allows network transactions on the computer to resolve the right targets on the network when the instructions carry a “people-friendly” hostname (e.g. wavd-mcs01) rather than an IP address (e.g. 192.XXX.XXX.XXX). Querying and waiting for a response from a DNS server can be slow due to network latency. The hosts file assists in quickly resolving hostnames to IPs which is particularly important for clustered configurations. By default the hosts file on a computer resolves the machine’s own IP address to localhost. In this step, you verify the content of the hosts file, and remove any extra entries, if present. In addition, since the active hosts file can be reset to its default configuration when a server fails or is rebooted you also verify the system default hosts file. 1. Using the following command, open the active hosts (/etc/hosts) file for editing: vi /etc/hosts It should look similar to the following: 127.0.0.1 ::1 localhost localhost.localdomain localhost4 localhost4.localdomain4 localhost localhost.localdomain localhost6 localhost6.localdomain6 In this example, the default IP address of 127.0.0.1 is mapped to various forms of localhost, for both ipv4 and ipv6 systems. In some cases, the entries include an explicit call-out of the computer’s own host name (e.g. wavd-mcs01): 127.0.0.1 ::1 localhost localhost.localdomain localhost4 localhost4.localdomain4 wavd-mcs01 localhost localhost.localdomain localhost6 localhost6.localdomain6 wavd-mcs01 Note: In a cluster the explicit call-out of the computer’s own host name is particularly problematic. If this entry remains unaltered, another node querying "wavd-mcs01" for its IP address would receive "127.0.0.1" in response. The node that did the querying would send messages to itself instead of to the real "wavd-mcs01", and clustering would not function normally. 2. If the computer’s own host name is present (e.g. wavd-mcs01), remove it: 127.0.0.1 ::1 localhost localhost.localdomain localhost4 localhost4.localdomain4 localhost localhost.localdomain localhost6 localhost6.localdomain6 3. If you will be configuring an MCS cluster, you will want to add the IP addresses, FQDN and hostnames of each of the cluster nodes. For a four node cluster, for example, you would add four lines similar to the following: 127.0.0.1 localhost localhost.localdomain localhost4 ::1 localhost localhost.localdomain localhost6 192.168.10.51 wavd-mcs01.wavd.com wavd-mcs01 192.168.10.52 wavd-mcs02.wavd.com wavd-mcs02 192.168.10.53 wavd-mcs03.wavd.com wavd-mcs03 192.168.10.54 wavd-mcs04.wavd.com wavd-mcs04 localhost4.localdomain4 localhost6.localdomain6 72 MCS 2.3 Installation and Configuration Guide Note: It is a good idea to declare the nodes in the hosts file in order of latency, ascending. Run a ping command to each node and add the lines to the file in order of the ping return. For example, if node-2 returns a ping after 30ms and node-3 after 20ms, put in the line for node-3 before node-2. 4. Save and exit the vi session. Press and type: :wq 5. If you made changes, verify that the system default hosts file reflects the changes. cat /etc/sysconfig/networking/profiles/default/hosts If necessary, “vi” can be used to edit the file to match the changes you made to toe master hosts file. Verifying the Contents of resolv.conf and nsswitch.conf Verifying the resolv.conf file: The resolv.conf file contains your DNS and domain information. 1. Verify the DNS Server information has been stored in the RHEL resolver configuration (resolv.conf) file: cat /etc/resolv.conf The DNS servers and DNS search path should be present in the file. Using the vi editor, one or more additional search domains can be entered if necessary. The search list is limited to six domains with a total of 256 characters. The file should look something like: nameserver (Primary DNS server) nameserver (Secondary DNS server) search domain1.com domain2.com single space or tab can be entered) (multiple domain names separated by a 2. Delete any backup resolver configuration (resolv.conf.save) file that might have been automatically created by the OS: rm /etc/resolv.conf.save Note: Due to a caveat in Linux, if you do not delete the resolv.conf.save file, when you reboot, Linux overwrites the changes you just made. Verifying the nsswitch.conf file: Avid adjusts the nsswitch.conf file to instruct RHEL to prefer the local hosts file over DNS. In cluster configurations, this ensures that there is no latency when attempting to discover the cluster nodes. 1. Type: cat /etc/nsswitch.conf | grep hosts 73 MCS 2.3 Installation and Configuration Guide The system outputs the lines containing the string “hosts”, similar to the following: #hosts: db files nisplus nis dns hosts: files dns In the second line, ensure the word “files” comes before the word “dns”. 2. If “files” does not appear before “dns”, use the vi editor to reverse the priority order. Ensuring the NIC Interface Comes Up at System Startup In this step you verify that the primary network interface is set to come up when the system boots. 1. Using the Linux text editor, vi, open the interface configuration file for eth0 for editing: vi /etc/sysconfig/network-scripts/ifcfg-eth0 Note: If you are on a Dell server, remember to substitute “em1”, “p1p1” for “eth0”. 2. When you open the file for editing, it should look something like this: DEVICE=eth0 HWADDR=00:60:dd:45:15:11 TYPE=Ethernet UUID= ONBOOT=yes NM_CONTROLLED=no DHCP_HOSTNAME=’$HOSTNAME’ BOOTPROTO=none IPADDR=192.169.10.51 NETMASK=255.255.255.0 DNS1=192.169.10.10 DNS2=192.169.10.20 GATEWAY=192.168.10.1 USERCTL=no IPV6INIT=no 3. Ensure that the ONBOOT entry is set to “yes”. If it is not, the interface will not be active after rebooting the server. 4. Save and exit the vi session. Press and type: :wq 5. Reboot the MCS server: reboot Note: You are asked to reboot at this time to ensure that all networking changes are active and the system comes up as expected. If you do not reboot, some of the steps in the next procedure will fail. 6. Once the system has rebooted, log back into RHEL. 74 MCS 2.3 Installation and Configuration Guide Verifying Hostname, Network and DNS Connectivity Before continuing, take a moment to verify that the server’s hostname responds as expected and that network connectivity is now established. To verify the hostname: 1. Verify the short hostname. In the RHEL command prompt, type: hostname The short hostname (e.g. wavd-mcs01) should be print to the screen. 2. Verify the fully qualified domain name (FQDN). In the RHEL command prompt, type: hostname -f The fully qualified hostname (e.g. wavd-mcs01.wavd.com) should be print to the screen. If you do not receive the expected output, verify your hosts file and the resolv.conf file. To verify network connectivity: 1. Use the ping command to verify connectivity to your network gateway address. ping –c 4 “ping” is the command. “-c 4” is the count of how many times the ping command is issued. If you do not specify a count, ping will continue forever. In that event, press CTRL-C to stop the ping. Example: [root@wavd-mcs01 ~]# ping -c 4 192.168.10.1 PING 192.168.10.1 (192.168.10.1) 56(84) bytes of data. 64 bytes from 192.168.10.1: icmp_seq=1 ttl=255 time=0.362 64 bytes from 192.168.10.1: icmp_seq=2 ttl=255 time=0.330 64 bytes from 192.168.10.1: icmp_seq=3 ttl=255 time=0.302 64 bytes from 192.168.10.1: icmp_seq=4 ttl=255 time=0.804 ms ms ms ms 2. Now use the ping command to test the connection to host servers in your network. Examples of host servers could be: Interplay Production Engines, ISIS servers, iNEWS servers, etc. This will not only test connection to the host server, but also verifies DNS. ping –c 4 3. Verify the same test, this time by pinging the host servers by IP address. Note: Now that you have configured and verified the connection to the network, you can now switch to using an indirect method for configuring the server. For more information refer back to Accessing the MCS Server(s) on page 14. 75 MCS 2.3 Installation and Configuration Guide Configure Date and Time Settings Ensuring that the date, time and time zone are correct on each MCS server is critical to a successful implementation. This process will walk you through configuring the above values as well as setting a Network Time Protocol (NTP) source for continued time synchronization. If you do not have an NTP server already configured, see your local IT Department about creating one prior to continuing with this process. Maintaining time synchronization between MCS servers and host systems (ISIS, Interplay Production, etc) is critical. Maintaining time synchronization between nodes in an MCS cluster configuration is particularly critical. Setting the Time Zone 1. The installation script sets the default location to “America/New_York”. Verify this by viewing the contents of the Linux “clock” file. cat /etc/sysconfig/clock If the US/Eastern time zone is appropriate for your installation, skip this process. Otherwise, continue… 2. List the contents of the directory containing RHEL time zone information: ls /usr/share/zoneinfo A list of time zone regions is presented. For example: US time zones are located in: /usr/share/zoneinfo/US (standard US time zones) European time zones are located in: /usr/share/zoneinfo/Europe And so on... 3. List the contents of the directory that are specific to your location. Example: ls /usr/share/zoneinfo/US 4. Make note of the time zone name that relates to your installation. 5. Edit the clock file to reflect the correct time zone for your installation. vi /etc/sysconfig/clock Example: Replace zone="America/New_York" with zone="US/Pacific" 6. Save and exit the vi session. Press and type: :wq 7. Create the symbolic link RHEL needs to make use of the new time zone information: ln –sf /usr/share/zoneinfo/ /etc/localtime In the above command, is the path you entered in the clock file (e.g. US/Pacific). 76 MCS 2.3 Installation and Configuration Guide Note: Creating a symbolic link is more robust than copying. For example, the files in /usr/share/zoneinfo contain daylight saving time (DST) information. A symbolic link allows your system to automatically accommodate changes to DST practices that might arise in the future. Such changes would be propagated through RHEL updates to the /usr/share/zoneinfo files. 8. Verify the settings using the date command: date The local time and time zone should now be shown. Synching the System Clock In this step you set the Network Time Protocol (NTP) daemon to automatically synchronize the system clock with an NTP time server every 30 minutes. This is done by creating a job for the Linux cron utility. The cron job runs the NTP daemon, ntpd. Note: Setting up ntpd to run as a service at startup is also a possibility. However, some consider it a security risk to run ntpd in “continuous” mode. The technique shown here keeps the system clock synchronized while minimizing exposure to risk by causing ntpd to exit after it fetches the correct time. Note: The use of the iburst option within the cron job is not recommended. It produces very rapid time shifts and can lead to synchronization problems. 1. Verify the current date and time with the date command. Type: date 2. This process will verify connectivity to the NTP server. Change the date and time so that the clock is 10 minutes behind the correct time of day. date MMDDHHmmYYYY Note: If you set the clock more than 1000ms (~17min) off from your NTP server, the time may not update. 3. Check the status of the ntpd service. Type: service ntpd status If the service is running, stop the service. Type: service ntpd stop 4. Verify that the NTP server of interest is reachable by querying it: ntpdate -q Example output: server 192.168.10.25, stratum 3, offset 468.746036, delay 0.02585 1 Jan 13:05:00 ntpdate[7554]: step time server 192.168.10.25 offset 468.746036 sec 5. Edit the NTP configuration (ntp.conf) file: vi /etc/ntp.conf 77 MCS 2.3 Installation and Configuration Guide 6. Scroll down to the section of the file that details the NTP servers and place a ‘#’ symbol in front of any existing NTP servers to comment them out. For example: # server 0.rhel.pool.ntp.org # server 1.rhel.pool.ntp.org # server 2.rhel.pool.ntp.org 7. Update the file with the NTP information for your configuration. Updated example: # server 0.rhel.pool.ntp.org # server 1.rhel.pool.ntp.org # server 2.rhel.pool.ntp.org server 192.168.10.25 server 192.168.10.26 8. Save and exit the vi session. Press and type: :wq 9. Set up a cron job by creating a new file containing instructions for cron: vi /etc/cron.d/ntpd 10. Add a line with the instructions for cron: 0,30 * * * * root /usr/sbin/ntpd -q -u ntp:ntp The command above instructs cron to: • Run the cron job every 30 minutes as root. “0,30” is a comma-separated list (i.e. run at 0 minutes and 30 minutes). “*” is a special list indicating every value in the list (i.e. every hour, every day of the month, every month, every day of week). • The job is /usr/sbin/ntpd • The -q switch tells ntpd to exit after it sets the system clock • The -u switch tells Linux to run the job as user ntp, in user group ntp The general form of the cron command is the following: # Minute # (0-59) Hour (0-23) Day of Month Month (1-31) (1-12 or Jan-Dec) Day of Week (0-6 or Sun-Sat) 11. Save and exit the vi session. Press and type: :wq 12. Once again, verify the current date and time. It should be 10 minutes behind the correct clock. date 13. Update the system clock now by querying the NTP server with the NTP daemon: /usr/sbin/ntpd -q -u ntp:ntp The system responds with a message similar to the following: ntpd: time set +570.677029s 14. Verify the updated date and time: date 78 MCS 2.3 Installation and Configuration Guide Creating the File Cache on the RAID If your configuration does not include a RAID 5, continue to one of the following (as appropriate for your installation): • Configuring MCS for MediaCentral UX and Media Composer Cloud • Configuring MCS for Interplay MAM In an earlier step you might have created a RAID 5 for the cache using the “arrays” utility built-in to the server’s BIOS. In this step you will partition the RAID, create a logical volume for the RAID and mount the MCS cache on it. Partitioning the RAID In this procedure you partition the RAID and write the new partition table entry to disk using the GNU parted disk partitioning utility. The enclosure contains two devices of interest, the system disk (/dev/sda) and the RAID (/dev/sdb). Partitioning the system disk was performed automatically by the RHEL installer. You only need to partition the RAID, as indicated in this section. Note: Starting with RHEL 6.3, Red Hat creates a GPT volume when the MCS installation scripts initialize the cache volume during OS installation. GPT volumes must be handled using the GNU parted utility (rather than the Linux fdisk utility). To partition the RAID: 1. Use the GNU parted utility to ensure the RAID 5 HD device exists: parted –l Note: Note the command take a lower-case “L” (not a numerical “one”). Note: The Linux “fdisk -l” command can also be used to list the devices. However, it returns the following warning: WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted. 2. Find the free space on the /dev/sdb device: parted /dev/sdb p free Information similar to the following is displayed: Model: HP LOGICAL VOLUME (scsi) Disk /dev/sdb: 2500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start 17.4kB End 2500GB Size 2500GB File system Free Space Name Flags 79 MCS 2.3 Installation and Configuration Guide 3. Create a primary partition on the RAID 5 using all the available space (2500 GB in the sample output provided above): parted -a optimal /dev/sdb mkpart primary ext2 0% 2500GB The system might respond with the following message: Information: You may need to update /etc/fstab The message can be ignored. You will update fstab when you create the logical volume and mount the cache for the new partition. 4. Set sdb partition one to type logical volume, and its state to on. parted /dev/sdb set 1 lvm on 5. Run the parted utility again to list your changes: parted -l Model: HP LOGICAL VOLUME (scsi) Disk /dev/sdb: 2500GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number 1 Start 17.4kB End 2500GB Size 2500GB File system Name primary Flags lvm Notice in the above output the partition now has a partition number, is the primary partition, and has a logical volume flag. You create the filesystem in the next step. Creating the Logical Volume, Filesystem and Mounting the Cache In this procedure you work with the newly partitioned RAID 5 using the Linux Logical Volume Manager (LVM). The hierarchy of volumes in Linux is as follows: physical volume, volume group and logical volume. To create the logical volume and mount the cache: 1. Create the physical volume: pvcreate --metadatasize=64k /dev/sdb1 Note the name of the physical volume (/dev/sdb1) takes a 1 (one). LVM feedback indicates the successful creation of the physical volume. 2. Create a volume group, vg_ics_cache, containing the physical volume /dev/sdb1: vgcreate -s 256k -M 2 vg_ics_cache /dev/sdb1 LVM feedback indicates the successful creation of the volume group. 80 MCS 2.3 Installation and Configuration Guide 3. Before creating the logical volume, obtain a value for the volume group’s physical extents: vgdisplay vg_ics_cache A list of properties for the volume groups appear, including the physical extents (Free PE). Physical extents are the chunks of disk space that make up a logical volume. Sample output is shown below: --- Volume group --VG Name System ID Format Metadata Areas Metadata Sequence No VG Access VG Status MAX LV Cur LV Open LV Max PV Cur PV Act PV VG Size PE Size Total PE Alloc PE / Size Free PE / Size VG UUID vg_ics_cache lvm2 1 2 read/write resizable 0 1 1 0 1 1 1.09 TiB 256.00 KiB 4578332 0 / 0 4578332 / 1.09 TiB cyWpGZ-s3PG-8UqH-4TBl-rvBA-33oJ-3uZt0u Use the “Free PE” value to create a logical volume occupying the entire volume group (below). 4. Create the logical volume, lv_ics_cache, containing the volume group vg_ics_cache: lvcreate -l -r 1024 -n lv_ics_cache vg_ics_cache In the above command, replace with the value obtained in the previous step. This is the number before the slash in the “Free PE” line. No unit is needed. For example: lvcreate -l 4578332 -r 1024 -n lv_ics_cache vg_ics_cache Note the first switch in lvcreate is lower case “L”. LVM feedback indicates the successful creation of the logical volume. Note that Linux may override the sector size you specified. That is OK. 81 MCS 2.3 Installation and Configuration Guide 5. Create a filesystem on the logical volume (i.e. format it): mkfs.ext4 /dev/vg_ics_cache/lv_ics_cache Note in the above command you specify logical volume by its Linux block device name (/dev/ / ). As in other operating systems, formatting in RHEL is a slow operation. Please be patient. Feedback similar to the following indicates success: This filesystem will be automatically checked every 38 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. 6. Edit the filesystem table: vi /etc/fstab 7. Add an entry at the end of the file: /dev/mapper/vg_ics_cache-lv_ics_cache /cache ext4 rw 0 0 This automates the mapping of the logical volume to a filesystem directory (/cache in this case). 8. Save and exit the vi session. Press and type: :wq 9. Mount the volume: mount /dev/mapper/vg_ics_cache-lv_ics_cache /cache Alternately, since you added an entry to fstab, you ought to be able to mount the cache as follows: mount /cache Note: If you receive an error indicating the mount point /cache does not exist, create the cache manually and issue the mount command again: mkdir /cache mount /dev/mapper/vg_ics_cache-lv_ics_cache /cache 10. Verify that /cache has been mounted correctly: df –h The following information is displayed about the cache: size, used, available, user % and mount point (mounted on), similar to the following: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_ics_cache-lv_ics_cache 29G 585M 27G 3% /cache 82 MCS 2.3 Installation and Configuration Guide 11. Verify that /cache has the correct ownership and read-write-exec settings: ls -la /cache Information is displayed about the cache ownership, similar to the following: drwxr-xr-x 5 maxmin maxmin 4096 Oct 16 10:02 . 12. If the ownership is of /cache is not set to user maxmin, change its ownership: chown maxmin:maxmin /cache 13. If the /cache directory does not have its read-write-exec settings are not rwx for owner, group, other, change the permissions: chmod 0777 /cache 14. Create the following two cache directories: mkdir /cache/download mkdir /cache/fl_cache 15. Change their ownership to user maxmin: chown maxmin:maxmin /cache/download chown maxmin:maxmin /cache/fl_cache 16. Change their permissions: chmod -R 02777 /cache/download chmod -R 02777 /cache/fl_cache 17. Verify that /cache and its subdirectories now have the correct ownership, read-writeexec settings, and setgid special permission: ls -la /cache Updated information is displayed, which ought to be similar to the following: drwxrwxrwx 5 maxmin maxmin 4096 Mar 22 10:04 . Note: User maxmin owns the MCS process that writes to the cache. Avid processes will create subdirectories in /cache, on an as-needed basis. If you are deploying a cluster, you will revisit caching later in the installation to replicate the cluster contents using GlusterFS. 83 MCS 2.3 Installation and Configuration Guide Enable / Disable 3G and Edge Streams By default, MCS servers encode three different media streams for MediaCentral UX applications detected on mobile devices -- for Wi-Fi, 3G, and Edge connections. For Wi-Fi only facilities, it is recommended that you disable the 3G and Edge streams, to improve the encoding capacity of the MCS server. To Disable 3G and or Edge Streams: 1. Log in as root and edit the following file using a text editor (such as vi): /usr/maxt/maxedit/share/MPEGPresets/MPEG2TS.mpegpreset 2. In each of the [Edge] and [3G] areas, set the active parameter to active=0. 3. Save and close the file. To re-enable 3G or Edge, edit the file and reset the “active” value to 1. Copying Software to the MCS Server Now that the basic RHEL installation is complete, you might need to copy additional software to the MCS server. Common software includes: RHEL Security Patches MCS Software Updates Gluster file replication software (used in cluster configurations) Closed Captioning Service installer MAM Connector For information on how to copy software to an MCS server, see Copying Software to the MCS Server on page 176. Security Updates Once you have installed the operating system, please take a moment to resolve any outstanding RHEL security vulnerabilities. For information and links to KB articles with instructions, see the “Security Updates” section in the Avid MediaCentral Platform Services ReadMe. Install Software Patches Avid releases patches for MCS on a regular basis to assist in addressing customer issues and feature requests. Refer to the Avid MediaCentral Platform Services ReadMe for information on current patches and install any available patches at this time. 84 MCS 2.3 Installation and Configuration Guide PART IV: C ONFIGURING MCS 85 MCS 2.3 Installation and Configuration Guide Chapter Overview This chapter is divided into two main sections. Proceed to the section appropriate for your installation: - Configuring MCS for MediaCentral UX and Media Composer Cloud This section includes information on multiple workflows such as iNEWS, Interplay Production, Media Composer Could, Send To Playback, etc. Read and apply the sections appropriate for your installation. o - Configuring MCS for Interplay MAM The following table describes the topics covered in this chapter. Step Task Time Est. Configuring MCS for MediaCentral UX and Media Composer Cloud 1 Updating the MediaCentral UX Configuration 2 min Covers use of the Configurator Tool. 2 Logging into MediaCentral UX 5 min Log in to MediaCentral for the first time. 3 Changing the Administrator Password 2 min For security it is recommended you change the administrator password. 4 Creating a Second Administrator User 5 min Helps to ensure you do not get locked out of the interface. 5 Configuring System Settings varies Covers the configuration of the MediaCentral System Settings. 6 Verifying the System Settings varies A process for testing the configured settings. 7 Configuring Send To Playback Settings 5 min Configure settings for STP workflows. 8 Importing Domain Users 5 min Covers the process of importing Windows Domain Users. 9 Creating Local Users and Assigning Roles varies Information on creating local users and role assignments. 10 Continuing the Installation 1 min Suggestions for additional steps to continue your installation. 86 MCS 2.3 Installation and Configuration Guide Step Task Time Est. Configuring MCS for Interplay MAM 1 Configuring MCS for Interplay MAM 10 min Configure MCS to mount the filesystems on which Interplay MAM browse proxies reside. Configure Interplay MAM to use the MCS server or server cluster 87 MCS 2.3 Installation and Configuration Guide Configuring MCS for MediaCentral UX and Media Composer Cloud Now that you have installed and configured the operating system, you are ready to configure the software and settings specific to MediaCentral. As a reminder, if you are running a cluster, complete this section on the master node only. Settings will be replicated to the other nodes during the cluster configuration process. Updating the MediaCentral UX Configuration By default, the MediaCentral UX user interface contains functionality for all the MCS solutions it supports. Functions that are not required for your installation should be removed. If you are configuring a cluster, this step only needs to be completed on the master and slave nodes, but it is good practice to run the configurator on all nodes. This step can be completed on all nodes concurrently. 1. Start the configurator by typing the following at the Linux prompt: /opt/avid/avid-interplay-central/configurator The configuration UI appears. Note: Media Distribute (not shown) appears in the configurator UI only if it has been installed on the system (through a separate installer). 2. Select the appropriate application profile settings. The following table outlines typical settings by deployment type: MCPS Settings iNEWS Interplay Production Media Distribute MediaCentral & Media Distribute ON ON ON ON Standard MediaCentral ON ON ON OFF Interplay Production Only ON OFF ON OFF Media Composer Cloud ON OFF ON OFF 88 MCS 2.3 Installation and Configuration Guide MCPS Settings iNEWS Interplay Production Media Distribute Interplay MAM ON OFF OFF OFF iNEWS Only OFF ON OFF OFF For example, for an iNEWS-only deployment without video playback, you would enable iNEWS and disable MCPS Settings and Interplay Production. Note what each selection controls: • MCPS Settings: Toggles the MCPS group in the System Settings layout. This group provides access to the Load Balancer, Playback Services and Player settings details pages. • Interplay Production: Toggles the Interplay Production settings group. • iNEWS: Toggles the iNEWS settings group. • Media Distribute: Toggles the Interplay Media Distribute layout. 3. Use the Up and Down arrow keys to move between the options, Left and Right arrow keys to move between OK and Cancel, SPACEBAR to toggle the asterisks, and press Enter to confirm. • Asterisk = enabled • No Asterisk = disabled Now when you launch MediaCentral, the UI will be correctly configured for your deployment. Logging into MediaCentral UX MCS servers are configured using the MediaCentral UX System Settings. This configuration is completed through the use of a web browser such as Google Chrome. Note: If you are configuring a cluster, you configure the MediaCentral UX System Settings once on the master node only. Do not configure these settings on slave nodes. The slave nodes obtain settings from the master node through the clustering mechanisms. Complete all remaining sections of this chapter on the Master node only. When you sign in to MediaCentral for the first time (in this procedure) you are prompted to sign in to an iNEWS server, an Interplay Production system, or both. 1. Launch a web browser supported by MediaCentral. Supported browsers include: Google Chrome or Safari (on Mac OS). 2. Enter the URL of the MCS server In the address bar: • https:// where is the host name of the MCS server 89 MCS 2.3 Installation and Configuration Guide The Interplay Central sign-in screen appears. In place of the sign-in screen, you might see a warning indicating the connection is not private. The warning relates to SSL certificates. For the purposes of installing and configuring, ignore the warning: - Click Advanced and then the Proceed to (unsafe) link. In older versions of Chrome (previous to release 37), the following warning is shown instead: In the above case, click Proceed Anyway. Note: For information on configuring a trusted certificate, see the Avid KB: http://avid.force.com/pkb/articles/en_US/how_to/SSL-Certificates-for-server-to-browserconnections. 90 MCS 2.3 Installation and Configuration Guide 3. The first time any user signs in, the Avid Software License Agreement is presented. Click the Accept License Agreement button to proceed. 4. You are asked for login credentials. Depending upon what options were selected in the Interplay Configurator, you may be asked for Interplay and / or iNEWS login information. • User name: Administrator • Default Password: Avid123 If you created iNEWS and Interplay Production users called Administrator with the default MediaCentral Administrator password, select the “Use my MediaCentral Credentials” checkboxes. Otherwise, enter the user names and passwords for the iNEWS system, and the Interplay Production system. Note: If the security settings for one of these systems is inaccurate, you will see a warning message that states that the application is unable to authorize the sign-in name or password. This will be the case for any iNEWS credentials entered, since you have not yet specified the iNEWS server to be used. If you receive a warning, click the link provided and verify your security settings. 91 MCS 2.3 Installation and Configuration Guide 5. If you are using a Chrome browser, the first time you sign in to MediaCentral a dialog box asks if you want to use MOS plug-ins. MOS plug-ins are used in certain iNEWS workflows. Note: Selecting “yes” installs only the container needed for Active X controls. To make use of MOS plug-ins you need to install additional software as described in “Appendix C: Enabling MOS Active-X Plug-Ins” on page 210. Changing the Administrator Password For security reasons, it is strongly suggested that you change the password for the Administrator 1. While logged in as the Administrator, select Users from the Layout selector. 2. Expand the list of Administrators in the User Tree and locate the Administrator user. 3. Double-click the Administrator. Details for the user account will appear on the right. 4. Click the Change Password button in the Details pane, and enter a new password for the Administrator user. Note: MediaCentral v2.1 introduced strong password enforcement. This feature was made optional in v2.2; however the default is to have strong passwords enabled. See the Avid MediaCentral | UX Administration Guide for more information on this feature. 5. Click OK update the password information. A message appears indicating that the password was successfully changed. 92 MCS 2.3 Installation and Configuration Guide Creating a Second Administrator User In the event that you are locked out of MediaCentral for any reason, it is wise to create a second Administrator-level user. 1. While in the Users Layout, highlight the Administrators group in the User Tree. 2. Click the Create User button under the User Tree tab. 3. In the Details pane, assign a User Name. 4. Enter a Password and confirm the password. 5. Deselect the checkbox for “User must change password at next sign-in.” 6. Click the Save button in the bottom-right corner of the window.

A bar displays the progress while the user tree is loading. When the loading is complete, the root of the user tree appears. 10. Select the users or groups you wish to import and click the Import button. The users are imported into MediaCentral. Note: When users are imported into MCS, the user data is stored in the local user database. The fields in this database have a maximum limit of 255 characters. LDAP allows for some fields such as the “Distinguished Name” (DN) to be longer than 255 characters. If you find that some users are not imported into MCS, verify none of the fields associated with the domain user are longer than 255 characters. Creating Local Users and Assigning Roles If desired, create additional non-domain user accounts within MediaCentral UX. This could be useful if you have a guest user or contractor that may only need access to MediaCentral for a short time. You will also want to assign roles to the users you have created either manually or through domain import. See the Avid MediaCentral | UX Administration Guide for more information about user creation and role assignment. 105 MCS 2.3 Installation and Configuration Guide Continuing the Installation Depending upon your workflow, your installation could be complete. Proceed to one of the following sections as applicable: • PART V: CLUSTERING • PART VI: VERIFYING THE INSTALLATION • PART VII: INSTALLING THE CLOSED CAPTIONING SERVICE • PART VIII: INSTALLING THE MAM CONNECTOR • PART IX: MULTI-ZONE CONFIGURATION • Media Distribute Refer to the Media | Distribute Installation and Configuration Guide for detailed installation instructions. • Media Index Refer to the Media | Index Installation and Configuration Guide for detailed installation instructions. Review the Avid MediaCentral | UX Administration Guide and the Avid MediaCentral | UX User’s Guide for additional information on customizing your base installation. 106 MCS 2.3 Installation and Configuration Guide Configuring MCS for Interplay MAM For MCS to play Interplay MAM media, the filesystem containing the MAM proxies must be mounted on the MCS servers. The mounting is done at the operating system level using standard Linux commands for mounting volumes (e.g. mount). To automate the mounting of the MAM filesystem, create an entry in /etc/fstab. Note: Some proprietary storage solutions may require that you install and configure proprietary filesystem drivers or client software. Consult the documentation for the storage solution to be used by the Interplay MAM system. To determine the correct path to be mounted, examine the path associated with the MAM essence pool to which MCS is being given access. This is found in the Interplay MAM Administrator interface under the Essence Management Configuration tab. Look for the “MORPHEUS” entry and tease out the path information. It is likely that MCS has been given access to more than one MAM essence pool. Be sure to mount all the associated filesystems. Note: Configuration must also take place on the Interplay MAM side, to set up permissions for MCS to access MAM storage, to point Interplay MAM to the MCS server or server cluster, etc. For instructions on this aspect of setup and configuration, please refer to the Interplay MAM documentation. Note: This step can be performed at any time during the installation. Configuring the MediaCentral UI By default, the MediaCentral UI contains functionality for all the MCS solutions it supports. Functions that are not required for your installation should be removed. If you are configuring a cluster, this step can be completed on all nodes concurrently. See Updating the MediaCentral UX Configuration on page 88 for details on this process. 107 MCS 2.3 Installation and Configuration Guide Creating the MAM System User When integrating with Interplay MAM, a specialized user needs to be created within MediaCentral. Note: If you are configuring an MCS cluster, complete this step on the Master Node only. 1. With the MCS server up and running, log in to MediaCentral as the Administrator user. See Logging into MediaCentral UX on page 89 for details on this process. 2. Select Users from the Layout selector. 3. Create a special role for the MAM user by clicking on the Create Role button in the Roles pane. 4. Click the Create Role button. 5. In the Details pane, type the properties for the new role: • • • Role name (e.g. MAM) Advance License Do not assign the MAM role any layouts 6. Click Apply to save your changes. The new MAM role is added to the Roles pane. 7. Create the MAM system user by clicking the Create User button. 8. In the Details pane, type the properties for the new user: • • • • User name (e.g. MAMuser) Password Uncheck “User must change password at next sign-in” Check “User cannot change password 9. Drag the MAM role from Roles pane to the Role section of the Details pane for the new user. 10. Click Save to save your changes. The new MAM user is added to the User Tree, as a top-level user. 11. Ensure the System Settings on the Interplay MAM system are configured to make use of the assigned user name and password. Example: See the Avid MediaCentral | UX Administration Guide for more information about user creation and role assignment. 108 MCS 2.3 Installation and Configuration Guide Configuring the MCS Player Configuring the MCS Player setting allows you to monitor connections to the player through the MediaCentral System Settings>ICPS>Load Balancer page. Note: If you are configuring an MCS cluster, complete this step on the Master Node only. 1. While logged in as the Administrator, select System Settings from the Layout selector. 2. In the Settings pane, select ICPS> Player. 3. In the Server>Hostname field, enter the Fully Qualified Domain Name (FQDN) of the MCS server. The FQDN is the preferred value of this field, however the short hostname or IP address are also acceptable values. Example: wavd-mcs01.wavd.com Note: If you are in the process of setting up the first server in a cluster, enter the FQDN of the server you are working on (node1 of the cluster). Later in the process, you will update this field with the virtual cluster hostname. 4. Click Apply to save your changes. Continuing the Installation Depending upon your workflow, your installation could be complete. Proceed to one of the following sections as applicable: • PART V: CLUSTERING • PART VI: VERIFYING THE INSTALLATION • PART VIII: INSTALLING THE MAM CONNECTOR • PART IX: MULTI-ZONE CONFIGURATION 109 MCS 2.3 Installation and Configuration Guide PART V: C LUSTERING 110 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to guide you through the creation and configuration of a multiserver MCS cluster. The following table describes the topics covered in this chapter. Step Task Time Est. 1 Cluster Overview varies Overview information and prerequisite check for building the cluster. 2 Configuring the Player System Setting 5 min Process for updating the MediaCentral Player System Setting. 3 Configuring DRBD 10 min Initiate replication of the MCS PostgreSQL database. 4 Starting the Cluster Services on the Master Node 15 min Begin the cluster configuration on the Master node. 5 Adding Nodes to the Cluster 15min Connect all additional nodes to the cluster. 6 Replicating the File Caches using GlusterFS 1 hr Set up Gluster to mirror the caches, so each server in the cluster can easily use material transcoded by the others. 111 MCS 2.3 Installation and Configuration Guide Cluster Overview A cluster is a group of two or more MCS servers that work together to provide high-availability, load balancing and scale. Each server in a cluster is called a “node”. During the cluster configuration one server is identified as the Master node. If you have multiple MCS servers in a rack, the Master node is usually the top-most server in the rack. The second MCS server in the cluster is called the Slave node. In addition to load balancing and scale, it provides highavailability of some specialized MCS services. In the event of a failover, the Slave node becomes the new Master and owner of the MCS database. Additional nodes do not participate in highavailability; they provide load balancing and system scaling only. Throughout this process the nodes will be identified by the following: Master Node (node1): wavd-mcs01 / 192.168.10.51 Slave Node (node 2): wavd-mcs02 / 192.168.10.52 Load Balancing Nodes (node3, node4): wavd-mcs03 / 192.168.10.53, wavd-mcs04 / 192.168.10.54 The cluster is identified by the clients through a virtual cluster hostname and IP address. This allows the clients to connect to the cluster no matter which server is the current Master. Throughout this process the virtual cluster will be identified by the following: Virtual Cluster Name / IP: wavd-mcs / 192.168.10.50 Prior to proceeding with the cluster process, confirm the following: You have fully configured and tested the Master node. All other nodes should be configured through, but not including, Part IV of this document. Hostnames and IP’s of each cluster node (static IP’s are required for cluster configurations) The primary network interface on each node must have the same name (e.g. eth0, em1, etc). Virtual cluster hostname and a unicast IP address (used for communication between cluster and external systems – such as a MediaCentral client). A multicast IP address (used for internal communication between the cluster nodes). If necessary, a unicast IP can be used. However, specifying a unicast IP requires additional configuration. All hostnames and IP addresses, including the cluster’s virtual name and IP, are resolved normally through DNS. Consult the Pre-Flight Checklist for a complete list if installation prerequisites. http://avid.force.com/pkb/articles/en_US/readme/Avid-MediaCentral-Version-2-3-x-Documentation For detailed information on MCS Clusters, see the MediaCentral Platform Services Concepts and Clustering Guide on the Avid Knowledge Base. 112 MCS 2.3 Installation and Configuration Guide Configuring the Player System Setting When configuring and testing the Master Node, you entered the Fully Qualified Domain Name (FQDN) of the server in the MediaCentral System Settings. Prior to configuring the cluster, you need to alter this setting to reflect the cluster FQDN. 1. Using Chrome or another qualified browser, log into MediaCentral as the Administrator user. 2. Select System Settings from the Layout pull-down menu. 3. In the Settings pane, select ICPS> Player. 4. Server: Enter the Fully Qualified Domain Name (FQDN) of the virtual MCS server. Example: wavd-mcs.wavd.com 5. Click Apply to save the setting. 6. Logout and exit the browser. 113 MCS 2.3 Installation and Configuration Guide Configuring DRBD In a clustered configuration, MCS uses the open source Distributed Replicated Block Device (DRBD) storage system software to replicate its PostgreSQL database between the Master and Slave nodes. Even in a cluster with more than two nodes, DRBD runs on the Master and Slave nodes only. Note: This procedure assumes a 20 GB partition exists on the RAID 1 mirrored system drive (/dev/sda). If you are installing MCS on supported HP or Dell hardware using the MCS Installation USB Drive, the required partition (/dev/sda2) was automatically created for you. If you are installing MCS on a server from another vendor, see Installing MCS on Non-HP / Dell Hardware for Interplay MAM. Explanation (do not type this example) This procedure uses the drbd_setup command: drbd_setup [primary_host=" "] [secondary_host=" "] {[primary_ip=" "] [secondary_ip=" "]} {[primary_disk=" "] [secondary_disk=" "]} where: primary_host: Host name (e.g. wavd-mcs01) of the machine to serve as Master node for DRBD. secondary_host: Host name (e.g. wavd-mcs02) of the Slave node (the machine to serve as fail-over for DRBD). primary_ip: Optional. IP address (e.g. 192.XXX.XXX.XXX) of the Master node. Helpful when host primary_host specified does not resolve. secondary_ip: Optional. IP address (e.g. 192.XXX.XXX.XXX) of the Slave node. Helpful when secondary_host does not resolve. primary_disk: Optional. Name of the disk device reserved for DRBD on the Master node (/dev/sda2 by default). secondary_disk: Optional. Name of the disk device reserved for DRBD on the Slave node (/dev/sda2 by default). Note: The primary_disk and secondary_disk parameters are provided for special cases in which the partitions reserved for DRBD are in a non-standard location. In most cases, the /dev/sda2 values supplied by default will be sufficient. Note: The DRBD setup script is case-sensitive. The host names you enter must exactly match those defined for the master and non-master. 114 MCS 2.3 Installation and Configuration Guide 1. On the Master node, change to the directory containing the drbd_setup script: cd /opt/avid/cluster/bin 2. Run the drbd_setup script: ./drbd_setup primary_host="master hostname" secondary_host="slave hostname" The quotes are required in this command. The hostnames in this command are case sensitive. DRBD requires you to enter the short hostname and not the FQDN. The period-slash “./” in this command tells Linux to look for the script in the current directory. Note: If an error message appears indicating that the IP addresses cannot be identified using the host names, add the “primary_ip” and “secondary_ip” switches to the command: ./drbd_setup primary_host="master hostname" secondary_host="slave hostname" primary_ip="ip of master node" secondary_ip="ip of slave node" You might receive an error message indicating the bus is not running and/or a path does not exist, similar to the following: - error: bus is not running - error: Given --path is not exist: These errors can be ignored. 3. You might receive the following message: Found some data ==> This might destroy existing data! <== Do you want to proceed? [need to type 'yes' to confirm] This indicates the DRBD setup script has found the 20GB partition set aside for it and is about to take ownership of it. 4. Type yes (the whole word) at the prompt to continue with the setup. The system responds, and waits for the other DRBD node, with output similar to the following: Writing meta data... initializing activity log NOT initializing bitmap New drbd meta data block successfully created. success Waiting for secondary node ... 5. On the Slave node, change to the directory containing the drbd_setup script: cd /opt/avid/cluster/bin 115 MCS 2.3 Installation and Configuration Guide 6. On the Slave node, run the same drbd_setup command that you ran on the Master node. The Master node responds with output similar to the following: Secondary node found Node initialized with role: Primary Stopping postgresql-9.1 service: [ OK ] mke2fs 1.41.12 (17-May-2010) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 128000 inodes, 511975 blocks 25598 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=524288000 16 block groups 32768 blocks per group, 32768 fragments per group 8000 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912 Writing inode tables: 0/16 1/16 2/16 3/16 4/16 5/16 6/16 7/16 8/16 9/1610/1611/1612/1613/1614/1615/16 done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 23 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. partition mounted at /mnt/drbd Starting postgresql-9.1 service: [ OK ] Note: A fail message might appear when the drbd_setup script tries to start PostgreSQL. This is normal. Finally, information indicating synchronization is underway appears in the output, similar to the following (on the master node only). The synchronization process can take some time, since DRBD replicates at the block level. Node synchronization started 5% synchronized … 55% synchronized 97% synchronized Node synchronization finished 7. Wait until node synchronization is completed before proceeding to the next step. 116 MCS 2.3 Installation and Configuration Guide Starting the Cluster Services on the Master Node MCS supports both multicast and unicast for intra-cluster communication. This body of this guide provides instructions for configuring a cluster in a multicast environment (standard configuration). However, multicast requires multicast enabled routers. If your network does not support multicasting, see Unicast Support in Clustering for details on altering the configuration. 1. On the Master node only, assign the cluster multicast IP address. This is the IP that the cluster will use for communication between the nodes. a. If your network has no other multicast activity, the default multicast address of 239.192.1.1 is assumed in the following command: /opt/avid/cluster/bin/cluster setup-corosync --corosyncbind-iface=interface --rabbitmq_master="master hostname" b. If your network includes multicast activity (perhaps a second MCS system), specify a custom multicast address with the following command: /opt/avid/cluster/bin/cluster setup-corosync --corosyncbind-iface=interface --corosync-mcast-addr="multicast address" --rabbitmq_master="master hostname" Note: As of MCS v2.0, this command will not accept a multicast address outside of the 239.0.0.0/8 range. If specifying a non-239.x.x.x, you will see an error: “Multicast IP is not in subnetwork 239.0.0.0/8”. Explanation (do not type this example) This procedure uses the cluster setup-corosync command: cluster setup-corosync [corosync-bind-iface = ] {[--corosync-mcast-addr=" "]} {[--rabbitmq_master=" "]} where: --corosync-bind-iface: Identifies the name of the primary network interface. In an HP server, this is generally “eth0”. In a Dell server, this is generally “em1” for 1 Gb connections or “p1p1” / “p2p1” for 10 Gb connections (depending on which slot the card 10 Gb card has been installed). For Interplay MAM configurations with port bonding, this is generally “bond0”. Quotes are not required in this command. --corosync-mcast-addr: In configurations that do not use the default multicast address of 239.192.1.1, this command can be used to specify a custom multicast address. Quotes are required in this command. --rabbitmq_master: This specifies the (short) hostname of the Master node in the cluster (e.g. wavd-mcs01). This should be the same as the DRBD Master node specified in the drbd_setup process. Quotes are required in this command. 117 MCS 2.3 Installation and Configuration Guide Messages appear echoing the Corosync network binding process; followed by messages indicating that services are being stopped. At the end of the process, you are informed that the Corosync cluster engine has successfully started [OK]. The following is sample output: bind_iface=eth0 bind_network=192.168.10.51 mcast_addr=239.192.1.1 Avid Service: edit fl_xmd: no process killed . .. ... Starting Corosync Cluster Engine (corosync): [ OK ] Starting Pacemaker Cluster Manager: [ OK ] You may notice the following text appear during this process: Clustering node rabbit@nodename with rabbit@nodename... Error: cannot_cluster_node_with_itself Starting node rabbit@nodename.... …done Failed to join cluster, exiting!!. This message can be ignored as it simply indicates that this is the first node in the rabbit cluster. 2. On the Master node only, assign the cluster’s virtual unicast IP address. This is the IP that the cluster will use for communication with clients and external systems. /opt/avid/cluster/bin/cluster setup-cluster --cluster_ip="cluster IP address" --pingable_ip="router IP address" -cluster_ip_iface="eth0" --admin_email="comma separated e-mail list" --drbd_exclude="comma separated list of non-DRBD nodes" Explanation (do not type this example) This procedure uses the cluster setup-cluster command: cluster setup-cluster {[--cluster_ip=" "]} {[--pingable_ip=" "]} {[--cluster_ip_iface=" "]} {[--admin_email=" "}] {[--drbd_exclude=" "}] where: --cluster_ip: Identifies the unicast virtual IP address assigned to the cluster. --pingable_ip: This is an IP address that will always be available on the network - for example, the IP address of your default gateway (e.g. 192.168.10.1). -- cluster_ip_iface: Identifies the name of the primary network interface. In an HP server, this is generally “eth0”. In a Dell server, this is generally “em1” for 1 Gb connections or “p1p1” / “p2p1” for 10 Gb connections (depending on which slot the card 10 Gb card has been installed). For Interplay MAM configurations with port bonding, this is generally “bond0”. 118 MCS 2.3 Installation and Configuration Guide --admin_email: This is a comma separated list of e-mail addresses to which cluster status notifications are automatically sent. This command is not optional. If you do not want to receive e-mail notifications, enter a bogus email address. Note: At least one cluster administrator email address is mandatory (though not validated by the system). To change the email address later, see “Changing the Cluster Administrator Email Address” on page 202. --drbd_exclude: This is a comma separated list of the non-DRBD nodes in the cluster (e.g. wavd-mcs03, wavd-mcs04). This parameter prevents the non-DRBD nodes from running PostgreSQL. The comma-separated list of non-DRBD nodes must not contain any spaces between each entry, only a comma. Note: Quotes are required in each of the above commands. Error messages appear indicating missing resources and attributes. For example: ERROR: resource does not exist Error: performing operation: The object/attribute does not exist These can be ignored. Additional warning, error and info messages may also appear, similar to the following: WARNING: 125: AvidConnectivityMon: specified timeout 20s for start is smaller than the advised 60 ERROR: 125: rsc-options: attribute admin-email does not exist INFO: 125: commit forced These can be ignored. 3. Restart the following services so they register correctly on the newly created instance of the message bus: service avid-acs-messenger restart service avid-aaf-gen restart 4. Now that the clustering services are up and running on the master node, start the cluster monitoring tool: crm_mon This utility provides a “live view” of the cluster which can be useful as you add additional nodes to the cluster. Typing “crm_mon –f” will give you additional information about fail counts. Press CTRL-C to exit crm_mon. Note: If you are using a SSH tool such as PuTTY, open a second session to the Master cluster node and run the “crm_mon” monitoring tool in a dedicated window. 119 MCS 2.3 Installation and Configuration Guide Adding Nodes to the Cluster With the clustering services up and running on the Master node – the fully configured MCS server – add the other servers to the cluster. If your network does not support multicast activity, see Unicast Support in Clustering for details on altering the configuration. 1. On each of the non-master nodes in the cluster, complete one of the following: Note: See the previous section for more information on each of the following commands. a. If your network has no other multicast activity, the default multicast address of 239.192.1.1 is assumed in the following command: /opt/avid/cluster/bin/cluster setup-corosync --corosyncbind-iface=interface --rabbitmq_master="master hostname" b. If your network includes multicast activity (perhaps a second MCS system), specify a custom multicast address with the following command: /opt/avid/cluster/bin/cluster setup-corosync --corosyncbind-iface=interface --corosync-mcast-addr="multicast address" --rabbitmq_master="master hostname" As before, messages appear echoing the Corosync network binding process. The Avid UMS service is temporarily shut down. A message appears indicating the Corosync cluster engine has successfully started. The following is sample output: bind_iface=eth0 bind_network=192.168.10.51 mcast_addr=239.192.1.1 Shutting down UMS [ OK ] 2012-11-19 15:48:57.891 -0500 - info: Done. System is up-to-date. generic – stop [ OK ] boot – stop [ OK ] Starting Corosync Cluster Engine (corosync): [ OK ] 2. Restart the following services so they register correctly on the newly created instance of the message bus: service avid-acs-messenger restart service avid-aaf-gen restart Note: After this point, if you reconfigure any System Settings through the MediaCentral UI, the new settings are retained by the Master node only. Non-master nodes must be updated manually. On each non-master node, log in as root and run the following command: service avid-all reconfigure. 120 MCS 2.3 Installation and Configuration Guide Replicating the File Caches using GlusterFS When a playback request is sent to an MCS server, the media is obtained from the ISIS (or Standard FS storage) and is quickly transcoded into an alternate delivery format. The transcoded media is stored in the system’s “/cache” folder. In the case of a cluster, the transcoding is performed on the cluster node that received the playback request. To expedite playback of the same media for future playback requests (where the request may be handled by a different node), the contents of the “/cache” folder is automatically replicated to all cluster nodes. This is completed using Gluster, an open source software solution for creating shared filesystems. Note: Cluster and Gluster are independent from each other. Multiple MCS servers require a Cluster but may not require Gluster. See the MediaCentral Platform Services Concepts and Clustering Guide for more information on Gluster configurations. Installing GlusterFS In this step, you install the GlusterFS RPMs and create the folders where the caches will be located. This section is completed on all cluster nodes. 1. Ensure that you have obtained and copied the Gluster software. If you have not already completed this task, see Obtaining the Software for instructions. 2. Create a “gluster364” folder within the “installers” folder: mkdir /media/installers/gluster364 3. Copy the GlusterFS software packages to the “gluster364” folder. Ensure that the GlusterFS packages are the only items in this folder. If needed, see Copying Software to the MCS Server for more information. 4. Navigate to the directory containing the GlusterFS packages: cd /media/installers/gluster364 5. Install the Gluster packages using the Linux rpm command. rpm -Uvh * Note: Earlier versions of this guide required you to install all packages individually and in a certain order. This streamlined process installs all packages with a single command while maintaining the correct installation order. Ensure that only the GlusterFS .rpm files are contained in this folder. 6. Start the Gluster daemon, glusterd: service glusterd start 7. Create the RHEL physical directories that Gluster will use to build its GlusterFS filesystem: mkdir -p /cache/gluster/gluster_data_download mkdir -p /cache/gluster/gluster_data_fl_cache mkdir –p /cache/gluster/gluster_data_multicam 121 MCS 2.3 Installation and Configuration Guide Creating the Trusted Storage Pool With Gluster installed and running on each MCS server in the cluster, you will create the trusted storage pool. This section is completed on the Master node only. 1. Verify that you can ping the other servers in the cluster by their hostname: ping –c 4 “ping” is the command. “-c 4” is the count of how many times the ping command is issued. If you do not specify a count, ping will continue forever. In that event, press CTRL-C to stop the ping. 2. Repeat the above command to ping each cluster node. 3. Add the Slave node to the trusted storage pool: gluster peer probe This command adds to the trusted storage pool. For each successful “join”, the system responds as follows: peer probe: success Note: Only probe the other servers in the cluster. You do not need to “self-probe” the server you are issuing commands from. 4. Repeat the above command to add any additional cluster nodes. 5. Once you have probed each cluster node, verify peer status. gluster peer status The system responds by indicating the number of peers, their host names and connection status, plus other information. Example: Number of Peers: 1 Hostname: wavd-mcs02 Uuid: 220976c3-dc58-4cdc-bda3-7b2213d659fc State: Peer in Cluster (Connected) 122 MCS 2.3 Installation and Configuration Guide Configuring the GlusterFS Volumes Gluster uses its own filesystem, GlusterFS, which includes its own notion of volumes. GlusterFS volumes consist of underlying directories from the trusted storage pools. When you create a GlusterFS volume, you also configure its behavior. In MCS we make use of Gluster’s ability to automatically distribute and replicate data (mirror) across the trusted storage. Explanation (do not type this example) In this procedure, you create GlusterFS volumes for the physical cache folders already created. You created the following directories when you installed gluster. /cache/gluster/gluster_data_download /cache/gluster/gluster_data_fl_cache /cache/gluster/gluster_data_multicam This is done using the gluster volume create command, specifying the name of the GlusterFS volume and the underlying directory assets it consists of: gluster volume create gluster-cache replica transport tcp :/gluster_mirror_data/ :/gluster_mirror_data/ continuing, in the same line, for each host name, up to: :/gluster_mirror_data/ Where is the total number of nodes used. And through are the machine names (host names) of the nodes in the cluster. Example (do not type this example) To illustrate the command, consider an MCS server cluster consisting of four servers, wavd-mcs01, wavd-mcs02, wavd-mcs03 and wavd-mcs04. Further, suppose you want to replicate a directory called /cache. To create a GlusterFS volume called gluster-cache consisting of the /cache directories from each server in the cluster, you would issue the following command: gluster volume create gluster-cache replica 4 transport tcp wavd-mcs01:/cache wavd-mcs02:/cache wavd-mcs03:/cache wavd-mcs04:/cache In this step, you will create GlusterFS volumes associated with those physical cache folders. This section is completed on the Master node only. 123 MCS 2.3 Installation and Configuration Guide 1. Create a GlusterFS volume called gl-cache-dl consisting of the /cache/gluster/gluster_data_download folders: gluster volume create gl-cache-dl replica N transport tcp hostname1:/cache/gluster/gluster_data_download hostname2:/cache/gluster/gluster_data_download …continuing, in the same line, for each host name, up to: :/cache/gluster/gluster_data_download Where N is the total number of nodes used. And through are the machine names (host names) of the nodes in the cluster. 2. Create a GlusterFS volume called gl-cache-fl consisting of the /cache/gluster/gluster_data_fl_cache folders: gluster volume create gl-cache-fl replica N transport tcp hostname1:/cache/gluster/gluster_data_fl_cache hostname2:/cache/gluster/gluster_data_fl_cache …continuing, in the same line, for each host name, up to: :/cache/gluster/gluster_data_fl_cache Where N is the total number of nodes used. And through are the machine names (host names) of the nodes in the cluster. 3. Create a GlusterFS volume called gl-cache-mcam consisting of the /cache/gluster/gluster_data_multicam folders: gluster volume create gl-cache-mcam replica N transport tcp hostname1:/cache/gluster/gluster_data_multicam hostname2:/cache/gluster/gluster_data_multicam …continuing, in the same line, for each host name, up to: :/cache/gluster/gluster_data_multicam Where N is the total number of nodes used. And through are the machine names (host names) of the nodes in the cluster. 4. Start the GlusterFS volumes. gluster volume start gl-cache-dl gluster volume start gl-cache-fl gluster volume start gl-cache-mcam 124 MCS 2.3 Installation and Configuration Guide Setting Gluster Volume Ownership The following two directories must be owned by user maxmin and have group id set to maxmin: cache/gluster/gluster_data_download cache/gluster/gluster_data_fl_cache The directories above are associated with RHEL directories (/cache/fl_cache and /cache/download) used to store files for http-based streaming, such as media converted to FLV for file-based playback. They are also used to store media converted to Mpeg2TS for playback on iOS devices. The download directory contains links to simplify iOS playback. Restarting the Gluster daemon (glusterd) results in user ID and group ownership of the Gluster volumes being changed from maxmin to root, which breaks playback on iOS devices. Thus if a cluster node is rebooted, playback issues can arise. To prevent issues for an existing cluster, configure the two Gluster cache volumes to use the same UID and GID as the maxmin user, as described in the following procedure. This section is completed on all cluster nodes (slave first, master second, load balancing at any time): 1. Stop Pacemaker: service pacemaker stop 2. Stop Corosync: service corosync stop 3. Obtain the user ID of the user maxmin (this might be different on each machine): id -u maxmin 4. Change the user ownership of the gluster volume to maxmin using the user ID: gluster volume set gl-cache-dl storage.owner-uid gluster volume set gl-cache-fl storage.owner-uid In the above commands, do not type the angle brackets. Enter the number obtained in the previous step. Note: Do not alter the gl-cache-mcam (multicam) volume. It uses the default root ownership. 5. Obtain the group ID of the user maxmin (this might be different on each machine): id -g maxmin 6. Change the group ownership of the gluster volume to maxmin using the group ID: gluster volume set gl-cache-dl storage.owner-gid gluster volume set gl-cache-fl storage.owner-gid Note: Do not alter the gl-cache-mcam (multicam) volume. It uses the default root ownership. 125 MCS 2.3 Installation and Configuration Guide 7. Verify the success of the ownership changes: ls –la /cache/gluster Should return: drwxrwsrwx 3 maxmin maxmin 4096 Jan 12 09:51 gluster_data_download drwxrwsrwx 5 maxmin maxmin 4096 Jan 12 09:51 gluster_data_fl_cache drwxr-xr-x 3 root root 4096 Feb 5 08:33 gluster_data_multicam 8. Restart the GlusterFS service: service glusterd restart 9. Verify the ownership changes are sticky: ls –la /cache/gluster Should return same as before: drwxrwsrwx 3 maxmin maxmin 4096 Jan 12 09:51 gluster_data_download drwxrwsrwx 5 maxmin maxmin 4096 Jan 12 09:51 gluster_data_fl_cache drwxr-xr-x 3 root root 4096 Feb 5 08:33 gluster_data_multicam 10. Change ownership of any files residing in gluster_data_download and gluster_data_fl_cache: chown –R maxmin:maxmin /cache/gluster/gluster_data_download chown –R maxmin:maxmin /cache/gluster/gluster_data_fl_cache This is only absolutely necessary on systems that have already been running, where the Gluster daemon reset ownership to root. It should not be necessary on a fresh install. 11. Start Corosync: service corosync start 12. Start Pacemaker: service pacemaker start 126 MCS 2.3 Installation and Configuration Guide Making the RHEL Cache Directories With the GlusterFS volumes now created and Gluster service running, configure the local cache on each server in the cluster. This section is completed on all cluster nodes. 1. Create the following cache folders: mkdir mkdir mkdir mkdir mkdir /cache/download /cache/fl_cache /cache/mob-fetch /cache/render /cache/spooler Note: You created /cache/download and /cache/fl_cache earlier when setting up the RAID (see Partitioning the RAID on page 79). Moreover, if you are creating a cluster for a system that has already been set up and run, the above folders already exist. For example, if you are currently operating on the fully functional master node where you played back a media asset, some folders were created automatically. Ignore any “cannot create directory: file exists” warnings. 2. Change permissions on the following directories: chmod 0777 /cache/spooler chmod 0777 /cache/mob-fetch 3. Verify the success of all the changes: ls -la /cache Output similar to the following ought to be presented: drwxrwxrwx drwxr-xr-x drwxrwxrwx drwxrwxrwx drwxrwxrwx drwxrwxrwx drwxrwxrwx 9 33 2 5 55 2 9 maxmin root root root root root root maxmin root root root root root root 4096 4096 4096 4096 4096 4096 4096 Nov Nov Nov Nov Nov Nov Nov 4 4 4 4 4 4 4 10:13 13:34 20:04 20:03 13:50 10:04 14:05 . .. download fl_cache mob-fetch render spooler Note that in the output above the dot (“.”) directory represents the current directory, that is, /cache. 4. Navigate to the directory used by Linux to organize scripts run by the RHEL init program: cd /etc/rc.d 127 MCS 2.3 Installation and Configuration Guide 5. Open the local run command (rc.local) file for editing: vi rc.local The rc.local file contains commands to be run at the end of the boot cycle, but before Linux displays the command prompt. 6. Add the following lines: /bin/mount /cache/download /bin/mount /cache/fl_cache /bin/mount /cache/render /sbin/service avid-all restart The above lines mount the cache at the end of the boot cycle, when the network services are up. Restarting the avid-all service ensures the backend services have access to the newly mounted caches. 7. Save and exit the vi session. Press and type: :wq Changing Ownership and Mounting the GlusterFS Volumes With the GlusterFS volumes now created and Gluster service running, configure the local cache on each server in the cluster. It is important to change the ownership of two cache directories so that files written to them inherit the group affiliation. This section is completed on all cluster nodes. 1. Give the maxmin:maxmin user access to the following two folders (original data folders, not the cache folders created in the procedure above): chown maxmin:maxmin /cache/gluster/gluster_data_download chown maxmin:maxmin /cache/gluster/gluster_data_fl_cache Note: If you are creating a cluster for a system that has already been set up and run, the ownership has already been changed. 2. Set the group ID bit for the following two directories. This ensures new files written to the directories are owned by the group of the parent directory — maxmin, in this case — rather than by the process writing the files: chmod 2777 /cache/gluster/gluster_data_download chmod 2777 /cache/gluster/gluster_data_fl_cache Note: Setting the setgid special permission bit ensures files (and subdirectories) newly created in the directory inherit the group affiliation of the directory (maxmin), rather than inheriting it from the user/shell doing the writing. The setgid special permission — the “2” in the above chmod command — is especially important for deployments where the iOS application is used. 128 MCS 2.3 Installation and Configuration Guide 3. Verify the success of the operations: ls -la /cache/gluster Updated information is displayed, which ought to be similar to the following: drwxrwsrwx drwxrwsrwx 2 maxmin maxmin 4096 Nov 4 10:15 gluster_data_download 2 maxmin maxmin 4096 Nov 4 10:15 gluster_data_fl_cache The “s” in the group position indicates a special permission has been applied. 4. Mount the folders using the Linux mount command, specifying the type as glusterfs: mount -t glusterfs mount -t glusterfs mount -t glusterfs :/gl-cache-dl /cache/download :/gl-cache-fl /cache/fl_cache :/gl-cache-mcam /cache/render Where is the name of the server you are working on (e.g. wavd-mcs01). 5. Verify that caches have been mounted correctly: df –h The following information is displayed about the caches: size, used, available, user % and mount point (mounted on). In the following sample output, only the relevant lines are shown. Filesystem wavd-mcs01:/gl-cache-dl wavd-mcs01:/gl-cache-fl wavd-mcs01:/gl-cache-mcam Size 2.1T 2.1T 2.1T Used Avail Use% Mounted on 947M 2.0T 1% /cache/download 947M 2.0T 1% /cache/fl_cache 947M 2.0T 1% /cache/render 6. Navigate to the directory containing the filesystem table: cd /etc 7. Open the filesystem table file, fstab, for editing: vi fstab 8. Navigate to the end of the file and add the following lines (A to append): :/gl-cache-dl /cache/download :/gl-cache-fl /cache/fl_cache :/gl-cache-mcam /cache/render glusterfs glusterfs glusterfs defaults,noauto 0 0 defaults,noauto 0 0 defaults,noauto 0 0 Where is the name of the server you are working on (e.g. wavd-mcs01). These lines automate the mounting of the GlusterFS volumes to the folders used by MCS for caching (/cache/download, /cache/fl_cache and /cache/render). 9. Save and exit the vi session. Press and type: :wq 129 MCS 2.3 Installation and Configuration Guide Testing the Cache It is a good idea to test that Gluster is replicating the caches correctly. Test the cache setup by writing a file to one of the GlusterFS cache folders (e.g. /cache/download) on one server and verify it appears on the other servers. For example, the following Linux commands create two files: 1) toto.txt in /cache/download and 2) sample.txt in /cache/render: touch touch /cache/download/toto.txt /cache/render/sample.txt Ensuring Gluster is On at Boot Verify that the Gluster service starts on boot. This section is completed on all cluster nodes. 1. Check the Gluster service configuration: chkconfig --list glusterd This command returns the current Gluster service configuration. It likely looks like this: glusterd 0:off 1:off 2:off 3:off 4:off 5:off 6:off But it should look like this: glusterd 0:off 1:off 2:on 3:on 4:on 5:on 6:off 2. If all 6 run levels are off, type the following chkconfig glusterd on Verify that run levels 2-5 are now on by repeating the command in the previous step. 130 MCS 2.3 Installation and Configuration Guide PART VI: V ERIFYING THE I NSTALLATION 131 MCS 2.3 Installation and Configuration Guide Chapter Overview This chapter focuses on testing and verification of the completed installation. The following table describes the topics covered in this chapter: Step Task Time Est. 1 Testing the Basics varies Covers a range of tests to verify your completed installation. 2 Testing the Cluster Email Service 5 min Verifies that e-mails sent by the cluster will be delivered. 3 Testing Cluster Failover varies For configurations with a cluster, verifying failover is a crucial aspect of the installation and testing process. 4 Verifying ACS Bus Functionality 5 min Verifies that the ACS bus and dependent services are communicating normally. 5 Verifying the Status of RabbitMQ 5 min Verifies the status of the RabbitMQ messaging bus. 6 Validating the FQDN for External Access 5 min Verifies that the MCS server(s) are accessible over the network. 7 Backing up the MCS System Settings and the MCS Database 10 min Provides a process to backup and restore the MCS settings. 132 MCS 2.3 Installation and Configuration Guide Testing the Basics Because MCS provides workflows for many types of environments, testing steps may vary. Test the items that are applicable to your situation: Testing MCS for MediaCentral and Media Composer Cloud: • Can web-based clients log into MediaCentral? Can they play media? • Can mobile clients log into MediaCentral? Can they play media? • Can Media Composer Cloud clients log into MediaCentral. Can they play media? • Can you access and search the Interplay Production database? • Can you access and search the iNEWS database? • Can you create a sequence and Send To Playback? Note: Send To Playback is an excellent test as it simultaneously verifies connection to ISIS, Interplay Production, MediaCentral Distribution Service, Interplay Production Services Engine, Interplay Transcode and potentially Interplay STP Encode and Interplay Transfer Engine. • Can you Delivery media to a remote workgroup? Can you “Deliver To Me”? • Can Media Composer Cloud clients upload/download media? • Does the Messaging Pane delivery messages between MediaCentral Users? Does it deliver messages between MediaCentral and Media Composer? • Do Media Index searches return expected results? • For Multi-Zone configurations, can you log in to MediaCentral from a Slave zone? This tests the accessibility of the user database on the Master Zone. Testing MCS for Interplay MAM: • Proxy playback in the MAM Desktop • Proxy playback in the MAM Cataloger Application • MAM VideoAnalysis (video analysis of Proxy / Low-res material) • MAM Connector: Proxy playback of MAM assets in MediaCentral UX 133 MCS 2.3 Installation and Configuration Guide Testing the Cluster Email Service The cluster automatically sends email notifications to the administrator email address. This requires that the Linux postfix email service is running on the master node (and slave node, for failovers). In this section you verify that the postfix service is operating as expected. To test the cluster email service: 1. Verify the email service is running: service postfix status 2. The system should respond with the following: master (pid XXXX) is running... 3. If it is not running: a. Check the postfix service run-level configuration: chkconfig –-list postfix The configuration returned should look like this (run levels 2–5 on): postfix 0:off 1:off 2:on 3:on 4:on 5:on 6:off b. To enable run levels 2–5, type the following: chkconfig postfix on c. Start the service: service postfix start 4. Compose and send Linux mail command: mail –v The system responds by opening an email shell and prompting you for a subject line: Subject: 5. Enter a subject line and press Return: The system responds by moving the cursor into the body of the email. Type a line or two of text, as desired. Note: If the Backspace key types “^H” rather than deleting, exit the email shell by typing Ctrl-C (twice). Next, type the following at the Linux command line, and try again (do not type the quotation marks: “stty erase ^H”. 6. Type Ctrl-D to exit the email shell and send the email. The system responds with the following: Mail Delivery Status Report will be mailed to . 7. Check the in-box of the addressee for the email. 134 MCS 2.3 Installation and Configuration Guide Testing Cluster Failover If your configuration consists of a cluster, verifying the system’s ability to failover from the Master node to the Slave node (and back again) is very important. The cluster monitoring tool, “crm_mon”, provides a “live” view of the cluster and its associated resources. The tool can be launched in one of two ways: - crm_mon - crm_mon -f Specifying the “-f” asks the tool to display the status of the cluster with fail counts. Each time that a service fails, a node failure count is retained by the system. Except for the AvidAll service, the default threshold for failures of each service is two (2). Before testing the cluster, you will want to clear the fail counts. If you do not, the cluster will failover automatically, and perhaps unexpectedly, when the threshold is reached. To test cluster failover: 1. From a Windows machine, use an SSH utility such as PuTTY to open a remote session to any node in the cluster. Log in as the root user. 2. Launch the cluster monitoring tool, specifying the fail-count option: crm_mon -f This returns the status of all cluster-related services on all nodes, with output similar to the following example using two nodes (e.g. wavd-mcs01 & wavd-mcs02).

Additional services may appear in the monitoring utility depending upon your installation. Note: The prefix lsb shown in the cluster resource monitor indicates the named service conforms to the Linux Standard Base project, meaning these services support standard Linux commands for scripts (e.g. start, stop, restart). 3. Check the tool for failure counts. If failures exist, they will be displayed per node in the “Migration summary” area at the bottom of the window. Example: Migration summary: * Node wavd-mcs01: AvidIPC: migration-threshold=2 fail-count=1 AvidAll:0: migration-threshold=1000000 fail-count=58 * Node wavd-mcs02: AvidAll:2: migration-threshold=1000000 fail-count=77 Failed actions: AvidAll_monitor_25000 on wavd-mcs01 'not running' (7): call=574, status=complete, last-rc-change='Wed Jun 25 13:13:15 2014, queued=0ms, exec=0ms Note: Make sure your SSH window is large enough (vertically) to see the failure counts. 4. If failures exist, they need to be cleared before testing the failover: crm resource cleanup [ ] • • is the resource name of interest: AvidIPC, AvidUMS, AvidACS, etc. (optional) is the node of interest. Omitting the node cleans up the resource on all nodes. Note: If you receive an “object/attribute does not exist” error message, it indicates the resource is active on more than one node. Repeat the command using the group name for the resource (the “everywhere” form). For example, for the AvidAll resource, use AvidAllEverywhere. For AvidConnectivityMon, use AvidConnectivityMonEverywhere. 136 MCS 2.3 Installation and Configuration Guide Note: You can address the services contained in the postgres resource group (postgres_fs, AvidClusterIP and pgsqlDB) individually, or as a group. For example, to reset the fail count for AvidALL resource, issue the following command: crm resource cleanup AvidAllEverywhere Once all failures have been cleared, the Migration summary should look like the following: Migration summary: * Node wavd-mcs01: * Node wavd-mcs02: 5. Once the tool is free of failures, identify and make note of the Master node. 6. From a Windows machine, use an SSH utility such as PuTTY to open a second remote session to another node in the cluster. Make sure to specify a different node than the one opened in the previous SSH session. Log in as the root user. 7. Put the Master node into standby: crm node standby Replace with the hostname of the Master node (e.g. wavd-mcs01). 8. Observe the failover in the crm_mon utility within the other terminal session. The former Master node will be put into standby. The former Slave node will become the new master and services will begin to come online under that new Master node. Note: During the failover process, any active MediaCentral clients will receive a message indicating the need to log back in. Playback might be briefly affected. 9. If failure counts were added to the monitoring tool, clear them with the crm resource cleanup command. 10. Perform some basic testing of the system such as logging into MediaCentral, verifying access to the associated databases (Interplay, iNEWS), verify playback, etc. 11. Bring the standby node back online: crm node online Replace with the hostname of the offline node (e.g. wavd-mcs01). Observe in the crm_mon window as the offline node is brought back up and rejoins the cluster. This node will now take on the role of the Slave node. 12. If failure counts were added to the monitoring tool, clear them with the crm resource cleanup command. 13. Repeat the process to test failover in the opposite direction. Remember to clear any failure counts at the end of the process and verify basic functionality. 137 MCS 2.3 Installation and Configuration Guide Verifying ACS Bus Functionality The Avid Common Services bus (“the bus”) provides essential bus services needed for the overall platform to work. Numerous services depend upon it, and will not start — or will throw serious errors — if the bus is not running. You can easily verify ACS bus functionality using the acs-query command. On a master node, this tests the ACS bus directly. Although the ACS bus operates on the master and slave nodes only, by running acs-query on a non-master node you can validate network and node-to-node bus connectivity. To verify the ACS bus is functioning correctly: Query the ACS bus database using the acs-query command with using the --path option: acs-query --path=serviceType Output similar to the following ought to be presented: "avid.acs.registy" The above output indicates RabbitMQ, MongoDB and PostgreSQL are all running and reachable by the ACS bus (since no errors are present). It also indicates the “avid.acs.registry” bus service is available. Verifying the Status of RabbitMQ RabbitMQ is a messaging bus used by the top-level MCS services on each node to communicate with each other. It maintains its own cluster functionality independent of the Corosync cluster, but is often co-located on the same Master and Slave nodes. To verify that RabbitMQ is functioning properly: Request the status of the messaging bus using the rabbitmqctl command: rabbitmqctl cluster_status Example output for a two node cluster: [root@wavd-mcs01 ~]# rabbitmqctl cluster_status Cluster status of node 'rabbit@wavd-mcs01' ... [{nodes,[{disc,['rabbit@wavd-mcs01','rabbit@wavd-mcs02']}]}, {running_nodes,['rabbit@wavd-mcs01','rabbit@wavd-mcs02']}, {cluster_name,<<"rabbit@wavd-mcs01.wavd.com">>}, {partitions,[]}] ...done. If you do not see similar results or need additional information on RabbitMQ, including troubleshooting assistance, see: http://avid.force.com/pkb/articles/en_US/troubleshooting/RabbitMQ-cluster-troubleshooting More information on Corosync and RabbitMQ clustering can be found in the MediaCentral Platform Services Concepts and Clustering Guide. 138 MCS 2.3 Installation and Configuration Guide Validating the FQDN for External Access It is vital that the fully qualified domain name (FQDN) for the MCS server(s) is resolvable by the domain name server (DNS) tasked with doing so. This is particularly important when MediaCentral will be accessed from the MediaCentral mobile application (iPad, iPhone or Android device) or when connecting from outside the corporate firewall through Network Address Translation (NAT). In such cases, review the FQDN returned by the XLB load balancer. Ensure that the network administrator has assigned the FQDN a unique public IP address. Note: Currently, connecting to MediaCentral through NAT is supported only for single-server configurations, not clusters. To validate the FQDN of the MCS Servers: 1. Launch a web browser on your client(s) of interest. This could be: - iPad, iPhone or Android device - On a client outside of the corporate firewall through a VPN or NAT connection - On a client within the corporate firewall 2. Enter the following URL into the address bar: http:// /api/xlb/nodes/less/?service=xmd Where is the fully qualified domain name of the MCS server. In a cluster configuration, enter the FQDN of the first node in the cluster. For example: http://wavd-mcs01.wavd.com/api/xlb/nodes/less/?service=xmd The system returns a string similar to the following (line breaks added for clarity): {"status":"ok","data": {"xlb_service_ip":"10.XXX.XXX.XX", "xlb_service_port":5000, "xlb_node_ip":"10.XXX.XXX.XX/32", "xlb_node_name":"wavd-mcs", "xlb_node_full_name":"wavd-mcs01.subdomain.domain.net"}} Note: An example of a failed connection from an iOS device appears as follows: “Safari cannot open the page because the server cannot be found.” Note the following data of interest: Item Description xlb_node_ip The IP address of the node assigned to you for the current session. xlb_node_name The host name of the assigned node. xlb_node_full_name The FQDN of the assigned node. If connecting to MediaCentral from outside the corporate firewall through NAT, this domain name must resolve to an external (public) IP address. 139 MCS 2.3 Installation and Configuration Guide 3. Verify the output of the command: - In a single server configuration, the “xlb_node_full_name” should match the FQDN name entered in the Server field of the MediaCentral System Setting (System Settings>ICPS>Player>Server). - In a cluster configuration, the domain extension (e.g. wavd.com) displayed in “xlb_node_full_name” should match the domain extension used in the Server field of the MediaCentral System Setting (System Settings>ICPS>Player>Server). Note: In this case you are only matchingt he domain extension because the Server field in the MediaCentral System Settings specified the cluster name and not an individual node. If the output does not match, you may be able to log into MediaCentral on a remote client, but playback may not function. If MediaCentral will be accessed from outside the corporate firewall through NAT, ensure that this server is accessible. In particular, ensure the FQDN returned by the query is associated with a public address. 4. If you have a cluster, repeat the process to verify each individual cluster node. 5. If you have a cluster, repeat this command using the cluster’s FQDN (e.g. wavdmcs.wavd.com). The “xlb_node_full_name” will not return the cluster FQDN, but will instead return one of the cluster’s individual node names. The returned node name is based on whichever node is most available to respond at that time. Note: Refreshing the webpage may return a different node name. This is normal. Troubleshooting: If you are not getting the results you expect, work with your onsite IT Department to verify that your DNS includes forward and reverse entries for each MCS server and an entry for the virtual cluster hostname and IP. Make sure there are no duplicate entries that contain incorrect information (e.g. an invalid IP address). If you are still unsuccessful and you are not using NAT, an alternative option exists. MCS v2.0.2 added a feature for altering the “application.properties” file to instruct the MCS servers to return an IP address during the load-balancing handshake instead of a hostname. Note: This process is not supported for single-server systems using NAT. 1. Log in to the master node as the ‘root’ user. 2. Navigate to the following directory: cd /opt/avid/etc/avid/avid-interplay-central/config 3. This directory contains an “application.properties.example” file. Use the following command to rename this file to exclude the “.example” extension: mv application.properties.example application.properties 4. Edit the file using a text editor (such as vi): vi application.properties 140 MCS 2.3 Installation and Configuration Guide 5. Add the following text to the end of the file: system.com.avid.central.services.morpheus.media.UseIpForPreferredHost=true 6. Save and exit the vi session. Press and type: :wq 7. Repeat steps 1 – 6 on the slave node. 8. Once complete, the AvidIPC resource must be restarted. Issue the following command on any node in the cluster: crm resource restart AvidIPC Note: Restarting the AvidIPC resource will disconnect any users currently working on the system. 9. Once this process is complete, repeat the process for validating the FQDN of the MCS Servers. Backing up the MCS System Settings and the MCS Database With the MediaCentral or Interplay MAM server or server cluster set up and running, consider this an excellent moment to back up the system settings. In the event you need to re-image the server, or upgrade MCS, having a backup of the settings is invaluable. The system-backup script provided on the MCS Installation USB Drive backs up important files and directories, including NIC card settings, DNS settings, and so on. In addition, the script calls the avid-db command, which dumps and backs up the contents of the MCS database. The MCS database contains ACS (Avid Common Services, “the bus”), UMS (User Management Services) and MCPS (MediaCentral Playback Services) data. It collects all this information and backs it up to the USB drive itself. Note: In a cluster, the MCS database is replicated across the master and slave node, but it is only mounted on the master. Thus, the MCS database is only available for dumping and backup on the master node. If you are backing up multiple nodes in a cluster, rename the backup file for each node before proceeding to the next node. If you do not rename the backup file obtained from the master node, it will be overwritten by the backup from a non-master node and the contents of the MCS database will be lost (including user information). 141 MCS 2.3 Installation and Configuration Guide The following table lists the files and directories backed up and restored by the system-backup script. Directory/File Description /etc/sysconfig/* Network settings /etc/fstab (restored in /root) Filesystem settings /etc/resolv.conf DNS config file /etc/ntp.conf Network Time Protocol config file /etc/cron.d/ntpd Instructions for the Linux cron utility. /etc/snmp/snmpd.conf Simple Network Management Protocol (network monitor) /usr/maxt/maxedit/etc/* Maxedit settings (used by MCPS) /etc/udev/rules.d/70-persistent-net.rules NIC card settings /usr/maxt/maxedit/share/MPEGPresets/MPEG2TS. mpegpreset Defines encoding for iOS playback /etc/localtime Time zone info /etc/sudoers List of users with sudo privileges /opt/avid/etc/avid/avid-interplaycentral/ssl/jetty.keystore Jetty keystore and SSL certificates and usage passwords. /opt/avid/etc/avid/avid-interplaycentral/config/application.properties Pacemaker configuration (restored as /root/pcmk.conf) Pacemaker configuration /etc/corosync/corosync.conf Corosync config file /etc/drbd.d/r0.res DRBD config file MCS database MCS database, including user information. RHEL user names and passwords. Not backed up. Note: RHEL user names and passwords (such as the root user) are not backed up or restored by the system-backup script. After an upgrade, for example, logging in as “root” requires the default password. For the default root user password, contact your Avid representative. 142 MCS 2.3 Installation and Configuration Guide To back up the system settings and MCS database: 1. Mount the original MCS Installation USB drive that contains the system-backup script. For detailed instructions, see Copying Software Using a USB Drive on page 177. 2. Change to the mount point. For example: cd /media/usb 3. Back up the MCS settings and database using the backup script. ./system-backup.sh –b A backup file is written to the USB drive: /media/usb/sys-backup/ics_setup_files.tar.gz Since the system-backup script also calls the avid-db command, a backup of the MCS database is also written to the following directory (on the MCS server): /var/lib/avid/db/dumps The backup file on the server has a name has the following form: ALL-YYYYMMDD_HHMMSSZ.sql.gz.cr Note: Note the time stamp appended to the file name uses the Universal Time Code (UTC), not the local time. The following message indicates success: Backup setup successful! 4. Rename the backup file on the USB drive using the Linux mv command. For example: mv sys-backup sys-backup- The above command renames the directory containing the backup file just created. The backup file itself (ics_setup_files.tar.gz) remains unchanged inside the directory. Note: Renaming the backup file is particularly important if you are backing up multiple nodes in a cluster. Only the master node backup contains a complete set of backup information. If you do not rename the master node backup file, it will be overwritten by the backup from a non-master node. 5. Unmount the USB drive. For detailed instructions, see Copying Software Using a USB Drive on page 177. 6. If you have a cluster, repeat the process on each node. 143 MCS 2.3 Installation and Configuration Guide To restore the system settings and MCS database: In the event that you need to restore system settings to the MCS servers, the following process is provided. This step does not need to be completed when testing the system. 1. Mount the original MCS Installation USB drive that contains the system-backup script. For detailed instructions, see Copying Software Using a USB Drive on page 177. 1. Change to the mount point. For example: cd /media/usb 2. If you renamed the backup file, restore it to the original name. mv sys-backup- sys-backup 3. Restore the MCS settings and database using the backup script. ./system-backup.sh –r You are asked to confirm the restoration of the MCS database: Would you like to restore the database now? (y/n) 4. Type “y” (without the quotes) to confirm the action. You are asked to confirm the shutting down of the Avid services: All Avid services will be shut down before performing a database restore operation. Would you like to continue? [yes/no] 5. Type “yes” (spelled out in full, without the quotes) to confirm the action. Note: Be careful when typing your response to this question. Typing anything other than “yes” results in the script exiting without restoring the MCS database. Other items are restored, but not the MCS database. Services are shut down, the MCS database is restored, and services are restarted. The MCS database service is stopped, and you are prompted to restore the database. The following message indicates success: Restoration done! Your old fstab settings were saved in /root/fstab Please remove the USB key and reboot the server. Note: The filesystem table (fstab) file contains information to automate mounting volumes at boot time. It is not restored automatically. 6. Once the settings are restored, unmount and remove the USB drive. For detailed instructions, see Copying Software Using a USB Drive on page 177. 7. If you have a cluster, repeat the process on each node. 144 MCS 2.3 Installation and Configuration Guide PART VII: I NSTALLING THE C LOSED C APTIONING S ERVICE 145 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to guide you through the installation of the Closed Captioning (CC) Service introduced with MCS v2.3. The following table describes the topics covered in this chapter. Step Task Time Est. 1 Preparing the Software Package 5 min Process for copying and unzipping the CC installer. 2 Installing the Closed Captioning Service on a Single Server 5 min Process for installing the CC Service on a single MCS server. 3 Installing the Closed Captioning Service in a Cluster 15 min Process for installing the CC Service on an MCS cluster. The Closed Captioning Service adds new functionality to MediaCentral UX in the form of a Closed Captioning pane. Broadcasters in the United States and Canada face increased pressure to include closed captioning information in their content due to government regulations. Through this pane, editors can review, edit, and repackage closed captioning data contained in Sequences. Closed captioning data can also be imported from file and exported to file from within MediaCentral UX. Note: If the Closed Captioning service is not installed, the Closed Captioning pane will still be visible to users on all MCS 2.3 and higher systems. If the pane is selected without the installation of the service, the user will be informed the CC service needs to be installed. The process for upgrading an existing installation and performing a new installation of the Closed Captioning Service are the same. The upgrade process simply overwrites the appropriate files. Note: The Closed Captioning Service installation process disconnects any user currently logged in to MediaCentral UX. Ensure that all users save their sessions and log off during the installation or upgrade procedures. 146 MCS 2.3 Installation and Configuration Guide Preparing the Software Package If you have a cluster configuration, complete steps below on all cluster nodes. 1. Ensure that you have obtained and copied the Closed Captioning Service software to the MCS server(s). If you have not completed these tasks, see Obtaining the Software and Copying Software to the MCS Server for instructions. 2. Navigate to the directory where the CC Service installer has been copied. Example: cd /media/installers 3. If necessary, unzip the CC Service installer: unzip MediaCentral_ClosedCaptioning_Service_ _Linux.zip 4. If necessary, unpack the package containing the CC Service installations files: tar -xzvf MediaCentral_ClosedCaptioning_Service_ .tar.gz 5. Navigate to the newly created directory. cd MediaCentral_ClosedCaptioning_Service_ _ _Linux Installing the Closed Captioning Service on a Single Server 1. If you have not already done so, navigate to the directory containing the CC Service installation script “install.sh.” cd / 2. Run the CC Service installation script: ./install.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. The end of the CCS installation process should indicate a successful installation: Complete! Restarting avid-interplay-central on standalone node avid-ccc is not running [ OK avid-ccc [1] starting... [ OK avid-ccc [2] starting... [ OK avid-ccc [3] starting... [ OK avid-ccc [4] starting... [ OK avid-ccc [5] starting... [ OK Avid Interplay Central process has been started. Wait for Interplay Central web interface... Avid Interplay Central has been started successfully (31 seconds) ] ] ] ] ] ] 3. Verify the installation using rpm command: rpm -qa | grep avid-ccc The output should include the following lines: avid-ccc-anc- .x86_64 avid-ccc-cluster-config- .x86_64 avid-ccc- .x86_64 147 MCS 2.3 Installation and Configuration Guide Installing the Closed Captioning Service in a Cluster In a cluster deployment, the Closed Captioning Service is installed on all cluster nodes. A new AvidCCC resource is added to the cluster during installation. This resource is active on the master node and migrates to the slave node during a failover. The cluster upgrade involves the following steps: Preparing the Software Package Verifying Prerequisites Identifying the Master, Slave and Load-Balancing Nodes Taking the Cluster Offline Installing the Closed Captioning Service Software Bringing the Cluster Online Checking on the Cluster Status Verifying Prerequisites Prior to installing the Closed Captioning Service, verify the following: MCS is installed and configured on all servers in the cluster. All cluster resources should be online and free of errors. Use “crm_mon –f” to verify the cluster status. Identifying the Master, Slave and Load-Balancing Nodes There are three types of nodes in a cluster: master, slave, and load-balancing. The master “owns” multiple resources such as the cluster IP address. The slave assumes the role of master in the event of a failover. Additional nodes play a load-balancing role, but can never take on the role of master. To identify the master, slave, and load-balancing nodes: 1. Verify the current role of each node by logging in to any machine in the cluster as the root user and typing: crm_mon 2. To identify the master and slave nodes, look for the line containing “Master/Slave Set”. For example: Master/Slave Set: ms_drbd_postgres [drbd_postgres] Masters: [ wavd-mcs01 ] Slaves: [ wavd-mcs02 ] In this example, the master node is wavd-mcs01 and the slave node is wavd-mcs02. 148 MCS 2.3 Installation and Configuration Guide 3. To identify the load-balancing nodes, look for the line containing “Clone Set”: Clone Set: AvidAllEverywhere [AvidAll] Started: [ wavd-mcs01 wavd-mcs02 wavd-mcs03] In this example, the load-balancing node is wavd-mcs03. 4. Exit crm_mon by pressing CTRL-C on the keyboard. Taking the Cluster Offline Prior to installing the Closed Captioning Service, all nodes must be taken offline. To avoid accidental cluster failover, make sure to follow the order represented below. To take the cluster offline: 1. Begin taking the cluster off-line by putting the load-balancing nodes into standby mode: crm node standby 2. Next, put the slave node into standby mode: crm node standby 3. Finally, put the master node into standby mode: crm node standby Installing the Closed Captioning Service Software Complete the following process on all nodes in any order. However, be sure to bring the nodes back online in the correct order, as indicated in the instructions below. 1. If you have not already done so, navigate to the directory containing the CC Service installation script “install.sh”. cd / 2. Run the CC Service installation script: ./install.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. The end of the CCS installation process should indicate a successful installation: Complete! Cluster detected avid-ccc is not running avid-ccc is not running [INFO] chkconfig avid-ccc off Cleaning up AvidCCC on wavd-mcs01 Cleaning up AvidCCC on wavd-mcs02 Cleaning up AvidCCC on wavd-mcs03 Waiting for 3 replies from the CRMd.. OK [ [ OK OK ] ] Note: When installing the service on additional nodes, you will see one additional informational message: [INFO] Already configured, service has been stopped and disabled 149 MCS 2.3 Installation and Configuration Guide 3. Verify the success of the installation using rpm command: rpm -qa | grep avid-ccc The output should include the following lines: avid-ccc-anc- .x86_64 avid-ccc-cluster-config- .x86_64 avid-ccc- .x86_64 Bringing the Cluster Online With the Closed Captioning Service installed on all nodes, bring the cluster back online.

If there are fail counts listed, run the cluster resource manager cleanup command to reset them: crm resource cleanup [ ] is the resource name of interest: AvidCCC, AvidIPC, pgsqlDB (or another) (optional) is the node of interest. Note: If you receive an “object/attribute does not exist” error message, it indicates the resource is active on more than one node. Repeat the command using the group name for the resource (the “everywhere” form). For example, for the AvidAll resource, use AvidAllEverywhere. For AvidConnectivityMon, use AvidConnectivityMonEverywhere. Note: You can address the services contained in the postgres resource group (postgres_fs, AvidClusterIP and pgsqlDB) individually, or as a group. 150 MCS 2.3 Installation and Configuration Guide For example, to reset the fail count for AvidALL resource, issue the following command: crm resource cleanup AvidAllEverywhere Uninstalling the Closed Captioning Service In the event that you need to disable the Closed Captioning functionality, use the following process to uninstall the CC Service. This process will disconnect any users currently working on the system. Make sure all users save their work prior to completing this process. Uninstalling the CC Service on a Single Server 1. Navigate to the directory containing the CC Service installation files: cd / 2. Run the CC Service uninstall script: ./uninstall.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. The CC Service is uninstalled and the avid-interplay-central service is restarted. Uninstalling the CC Service on a Cluster 1. Verify the current Master, Slave and load balancing nodes. For details, see Identifying the Master, Slave and Load-Balancing Nodes on page 148. 2. Take the cluster offline. For details, see Taking the Cluster Offline on page 149. 3. On each node, navigate to the directory containing the CC Service installation files: cd / 4. Run the CC Service uninstall script: ./uninstall.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. 5. Repeat steps 3 and 4 on all cluster nodes. 6.

Verify the status of the cluster: crm_mon -f • Verify the master, slave, and load-balancing nodes are online. • Verify that the AvidCCC resource has been removed. • Verify that the AvidIPC resource is online on the master node. 151 MCS 2.3 Installation and Configuration Guide • Verify the fail counts for the following resources (at a minimum): AvidIPC, AvidUMS, AvidACS, pgsqlDB. • Verify the cluster status. 8. If there are fail counts listed, run the cluster resource manager cleanup command to reset them: crm resource cleanup [ ] is the resource name of interest: AvidIPC, pgsqlDB (or another) (optional) is the node of interest. Note: If you receive an “object/attribute does not exist” error message, it indicates the resource is active on more than one node. Repeat the command using the group name for the resource (the “everywhere” form). For example, for the AvidAll resource, use AvidAllEverywhere. For AvidConnectivityMon, use AvidConnectivityMonEverywhere. Note: You can address the services contained in the postgres resource group (postgres_fs, AvidClusterIP and pgsqlDB) individually, or as a group. For example, to reset the fail count for AvidALL resource, issue the following command: crm resource cleanup AvidAllEverywhere 152 MCS 2.3 Installation and Configuration Guide PART VIII: I NSTALLING THE MAM C ONNECTOR 153 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to guide you through the installation of the MAM Connector software. The following table describes the topics covered in this chapter. Step Task Time Est. 1 Preparing the Software Package 5 min Process for copying and unzipping the MAM Connector software. 2 Installing the MAM Connector on a Single Server 5 min Process for installing the MAM Connector on a single MCS server. 3 Installing the MAM Connector in a Cluster 15 min Process for installing the MAM Connector on an MCS cluster. 4 Uninstalling the MAM Connector varies In the event that you no longer require Interplay MAM workflows, the MAM Connector software can be easily removed. 5 Configuring the MAM Connector 5 min Once the MAM Connector has been installed, the MediaCentral System Settings must be configured. The MAM Connector enables Interplay MAM workflows in MediaCentral UX. The supported configuration for the MAM Connector requires you to install the connector on the MCS server, which is part of your MediaCentral configuration. The MCS server must be fully installed and configured prior to installing the MAM Connector. For MAM Connector compatibility with MCS please refer to the Avid MediaCentral Platform Services ReadMe. Note: The MAM connector installation process disconnects any user currently logged in to MediaCentral UX. Ensure that all users save their sessions and log off during the installation or upgrade procedures. 154 MCS 2.3 Installation and Configuration Guide Preparing the Software Package If you have a cluster configuration, complete steps below on the Master and Slave nodes only. 1. Ensure that you have obtained and copied the MAM Connector software to the MCS server(s). If you have not completed these tasks, see Obtaining the Software and Copying Software to the MCS Server for instructions. For the precise installation package name, see the Avid MediaCentral Platform Services ReadMe. The package is available from your Avid representative. 2. Navigate to the directory where the MAM Connector installer has been copied. Example: cd /media/installers 3. If necessary, unzip the MAM Connector: unzip MediaCentral_MAM_Connector_ _Linux.zip 4. If necessary, unpack the package containing the MAM Connector installations files: tar -xzvf MediaCentral_MAM_Connector_ _ .tar.gz 5. Navigate to the newly created directory. cd MediaCentral_MAM_Connector_ _ _Linux/ Installing the MAM Connector on a Single Server 1. If you have not already done so, navigate to the directory containing the MAM Connector installation script “install.sh”. cd / 2. Run the MAM Connector installation script: ./install.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. 3. Verify the success of the installation using rpm command: rpm -qa | grep mam The output should include the following line: avid-interplay-central-mam- . .noarch.rpm 4. Restart the avid-interplay-central service: service avid-interplay-central restart 155 MCS 2.3 Installation and Configuration Guide Installing the MAM Connector in a Cluster In a cluster deployment, the MAM connector is installed on the Master and Slave nodes. It is not installed on load-balancing nodes. Before You Begin Verify the following: MCS is installed and configured on all servers in the cluster All servers are set up and configured correctly for the cluster Failover processes work correctly Take the Cluster Offline Pacemaker tracks failure counts for various services in a cluster, and a failover from master to slave will automatically take place when a service’s threshold is reached. To prevent unintended failovers during installation of the MAM connector, bring the cluster offline first. 1. Verify the current Master, Slave and load balancing nodes. For details, see Identifying the Master, Slave and Load-Balancing Nodes on page 198. 2. Begin bringing the cluster off-line by putting the load-balancing nodes into standby mode: crm node standby 3. Next, put the Slave node into standby mode: crm node standby 4. Finally, put the Master node into standby mode: crm node standby Install the MAM Connector Software With all the cluster nodes offline, you are ready to install the MAM Connector software. Complete the following process on the Master node first. Once complete; repeat the process on the Slave node. 1. If you have not already done so, navigate to the directory containing the MAM Connector installation script “install.sh”. cd / 2. Run the MAM Connector installation script: ./install.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. 156 MCS 2.3 Installation and Configuration Guide 3. Verify the success of the installation using rpm command: rpm -qa | grep mam The output should include the following line: avid-interplay-central-mam- . .noarch.rpm 4. Restart the MediaCentral service: crm resource restart AvidIPC Bring the Cluster Back Online With the installation of the MAM Connector complete on both the Master and Slave nodes, bring the cluster back online. 1. First, bring the Master node online: crm node online Bringing the master node back online starts the Avid Interplay Central service (which was stopped when you put the node into standby). 2. Next, bring the Slave node back online: crm node online 3. Finally, bring the load-balancing nodes back online: crm node online 4. Verify the cluster status and cluster failover status crm_mon -f • Verify the Master, Slave, and load-balancing nodes have rejoined the cluster, as expected. • Verify the fail counts for the following resources (at a minimum): AvidIPC, AvidUMS, AvidACS, pgsqlDB. • Verify the cluster status. 5. If there are fail counts listed, run the cluster resource manager cleanup command to reset them: crm resource cleanup [ ] is the resource name of interest: AvidIPC, AvidUMS, AvidACS, pgsqlDB (or another) (optional) is the node of interest. Note: If you receive an “object/attribute does not exist” error message, it indicates the resource is active on more than one node. Repeat the command using the group name for the resource (the “everywhere” form). For example, for the AvidAll resource, use AvidAllEverywhere. For AvidConnectivityMon, use AvidConnectivityMonEverywhere. 157 MCS 2.3 Installation and Configuration Guide Note: You can address the services contained in the postgres resource group (postgres_fs, AvidClusterIP and pgsqlDB) individually, or as a group. For example, to reset the fail count for AvidALL resource, issue the following command: crm resource cleanup AvidAllEverywhere Uninstalling the MAM Connector In the event that you need to disable MAM functionality, use the following process to uninstall the MAM Connector. 1. If you are in a cluster configuration, see the process above for taking the cluster offline. 2. Navigate to the directory containing the MAM Connector installation script “install.sh”. cd / 3. Run the MAM Connector installation script: ./uninstall.sh The period-slash “./” in this command tells Linux to look for the script in the current directory. 4. Restart the MediaCentral service. For a single MCS server: service avid-interplay-central restart For a cluster configuration, run the following command on the Master node first. Once the service has been restarted, repeat on the Slave node. crm resource restart AvidIPC 5. If you are in a cluster configuration, see the process above for bringing the cluster back online. 158 MCS 2.3 Installation and Configuration Guide Configuring the MAM Connector Once the MAM Connector has been installed, additional System Settings must be configured within MediaCentral. 1. Log into MediaCentral. For details on this process, see Logging into MediaCentral UX on page 89. 2. While logged in as the Administrator, select System Settings from the Layout selector. 3. In the Settings pane, select Interplay | MAM. 4. Configure the settings to connect to your Interplay MAM system. For detailed information on the configuration of these settings, see the Avid MediaCentral | UX Administration Guide. 159 MCS 2.3 Installation and Configuration Guide PART IX: M ULTI -Z ONE C ONFIGURATION 160 MCS 2.3 Installation and Configuration Guide Chapter Overview The purpose of this chapter is to provide instructions on setting up a multi-zone environment. Configuration of a multi-zone workflow can be completed during the initial system installation or added to systems in an established environment. The procedures in this section cover single MCS nodes and MCS clusters that are already established. The following table describes the topics covered in this chapter: Step Task Time Est. 1 Multi-Zone Overview 5 min Provides an introduction to the Multi-Zone concept. 2 Creating and Installing the RSA Keys 5 min The multi-zone services must have access to remote servers directly, without the need to log in. Installing RSA keys creates a network of trust within the zone. 3 Creating the Master Zone and Initiating Multi-Zone 10 min Once the MCS nodes in the master zone and slave zone(s) are up and running, the multi-zone environment can be initialized. 4 Adding Slave Zone(s) to the Multi-Zone Environment 5 min With the master zone established, slave zone(s) can be added to the configuration. 5 Validating Multi-Zone Functionality 5 min Creating a user with a different role in each zone verifies that the multizone environment is working as expected. 6 Troubleshooting the Multi-Zone Setup varies This section offers solutions to typical problems encountered during setup. 7 Dismantling a Multi-Zone Environment 5 min Instructions for de-registering the multi-zone environment. 161 MCS 2.3 Installation and Configuration Guide Multi-Zone Overview By default, each MediaCentral system operates independently, within a single “zone”, with the following configuration: • One MediaCentral server or MediaCentral cluster • One Interplay Production engine and/or iNEWS database • ISIS storage system(s) A multi-zone environment comprises two or more single-zone systems joined together. The master zone maintains a read/write copy of the User Management System (UMS) database. Each slave zone has a read-only copy. All log-in activity in the slave zones is channeled through the master zone. In the event of a network disruption, the slave zones continue to operate in read-only mode until connectivity to the master zone is re-established. The benefits of a multi-zone environment include: • Multi-zone user management: Centralized user management across all zones. • Multi-zone central index search: Search across multiple databases in different zones • Multi-zone media asset delivery: Transfer material you found on a remote zone to your local zone. For example, in a single zone environment a user can search for assets in their own zone. In a multi-zone environment, a user in one zone can find media assets in remote zones, transfer them to their local zone, for use in their local work. Similarly, in a single zone environment, users log in to the locally configured MediaCentral system. If they log in to another MediaCentral system, they must have login credentials on that system too. In a multi-zone environment, one master server runs the user management service (UMS). All users, whatever their zone, log in through that system. Thus, each user requires only one set of login credentials. Making Changes to a Multi-Zone Configuration If changes are made to the multi-zone configuration after the initial setup, the MCS messenger service must be restarted on all nodes. Examples of such changes include: altering information contained in the initial multi-zone configuration process; adding or removing a zone. To restart the messenger service, do the following: Log in to each node of the cluster and type the following command: service avid-acs-messenger restart 162 MCS 2.3 Installation and Configuration Guide Creating and Installing the RSA Keys The multi-zone services must gain access to remote servers directly and without the need to provide log-in information. This is accomplished by generating RSA key(s) on the Master Zone and installing the key(s) on the Slave Zone(s). Generate the RSA keys in the master zone on the following nodes: Master node Slave node Install the generated RSA keys in the slave zone on the following nodes: Master node Slave zone To Generate and Install RSA Keys: 1. Log in (at the Linux prompt) to the master node in the master zone as the root user. 2. Generate the public/private RSA key pair using the RHEL ssh-keygen utility: ssh-keygen • Accept the default file and location • Leave the passphrase blank The system responds by outputting information similar to the following: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 55:66:25:00:f7:15:d5:cd:30:89:6f:0d:e2:c3:d4:4f root@wavd-mcs01.wavd.com The key's randomart image is: +---[ RSA 2048]---+ | o.B=+++Bo| | . o = .o.+.E| | o + + | | . . + .| | S . | | o . | | o o | | .o | +-----------------+ 3. Use the RHEL ssh-copy-id utility to add the public key to the list of authorized keys on the master node in the slave zone. ssh-copy-id root@ The system may respond with message similar to the following: The authenticity of host ' (XXX.XX.XX.XXX)' can't be established. Now multi-zone processes can gain access to the remote server automatically (without the need to provide root user credentials). 163 MCS 2.3 Installation and Configuration Guide 4. Copy the public key from the master node in the master zone to the slave node in the slave zone. 5. Repeat the procedure for the slave node in the master zone. Creating the Master Zone and Initiating Multi-Zone 1. Log in as the Administrator user to the MediaCentral UX instance located in the master zone, and select System Settings from the Layout selector. 2. In the Settings pane, click Zones. The Details pane appears on the right side of the screen. This pane displays the currently active zone(s). For now, only the “default” zone exists. Note that if the local zone is a cluster this is indicated in the UI: 164 MCS 2.3 Installation and Configuration Guide 3. Click the Activate Multi-Zone button. In the confirmation dialog that appears, click Proceed. A Zone Details dialog appears. 4. In the Zone Details dialog that appears, enter the following information: • Root Username and Root Password: The root user credentials for the master zone MCS server. • Zone Name: Name of the master zone (e.g. Master_Zone). • UMS Password: Administrator password for the master zone UMS database (e.g. Avid123). 5. Click Register. A dialog appears showing progress of the operations related to zone creation. Once registration of the master zone is complete, a dialog appears indicating success of the operations. 165 MCS 2.3 Installation and Configuration Guide 6. Click OK to close the dialog and complete the process. MediaCentral is automatically restarted. 7. Once restarted, log back in to MediaCentral UX. The Zones Details area now shows the newly created zone (e.g. Master_Zone): Adding Slave Zone(s) to the Multi-Zone Environment 1. Log in to MediaCentral UX in the master zone as the Administrator user. 2. Select System Settings from the Layout selector and Zones in the Settings pane. 3. Click the Add Slave Zone button. In the confirmation dialog that appears, click Proceed. The Zone Details dialog appears. 166 MCS 2.3 Installation and Configuration Guide 4. In the Zone Details dialog, enter the following information. Database Replication: • Master Zone Network: Specify the IP range for this network (e.g. 23, 24, 25) • Slave Zone Address: Specify the IP address of the slave zone. This is either the IP address of a single server or the IP address of a multi-server cluster. • Root Username and Root Password: Specify the username (root) and password for the slave zone. Zone Registration: • Zone Name: Name of the slave zone (e.g. Slave_Zone). This name will appear in the “Node URL” column in System Settings>Zones. • UMS Password: Administrator password for the slave zone UMS database (e.g. Avid123). 5. Click Register. A dialog appears showing progress of the operations related to slave zone registration. Once the slave zone registration is complete, a dialog appears indicating success of the operations. 6. Click OK to close the dialog and complete the process. Note: Any users logged into the slave zone will be disconnected at this time as services are restarted on the slave zone. 167 MCS 2.3 Installation and Configuration Guide 7. The Zones Details page is refreshed with the new slave zone. Note that the master zone is now identified with the letter “M” and the current zone is bolded. The “current zone” is the zone for the machine where you are currently logged in. 8. Repeat the process to add other slave zones, as desired. 9. Once all slave zones have been added, the avid-acs-ctrl-core service must be restarted on all zones, in any order. a. If your zone consists of a single server, restart the service: service avid-acs-ctrl-core restart b. If your zone consists of a cluster configuration, restart the cluster resource: crm resource restart AvidACS Validating Multi-Zone Functionality In this step you verify multi-zone UMS functionality by adding creating a user with different roles in each zone. To validate the multi-zone functionality: 1. Log in to MediaCentral UX as an administrator-level user in either the master zone or one of the slave zones. 2. Select Users from the Layout selector. 3. Observe that the Users layout now has an additional tab named MediaCentral Zones, where all the linked zones are displayed. 4. To validate that a user added to one zone can log in from another, begin by clicking the Create User button. In the Details pane, type the properties for the new user, at the very least: • User name (e.g. multzone_test) • Password • To simplify the test, uncheck “User must change password at next sign-in” 168 MCS 2.3 Installation and Configuration Guide 5. Drag a role for the user from the Roles pane to the Role section of the Details pane for the new user. Notice that you can assign the multi-zone user a different role in each zone. For example, the user can be an administrator in one zone, and a media logger in another. 6. Click Save to save your changes. The new user is added to the User Tree, and the Details pane is populated with the layouts available to the user in each zone. 7. Finally, log in to MediaCentral UX in the other zone using the newly created multi-zone user. • If you log in to a slave zone, note the user credentials are being validated in the master zone. • Notice the available layouts are those you assigned for the user upon creation. Troubleshooting the Multi-Zone Setup This section contains troubleshooting tips. Failed to Resolve Zone URL When registering the slave zone the following message indicates the zone is unreachable. Verify that the zone is online and the URL you entered is correct. The master zone URL is passed into the zone configuration processes automatically, based on the current URL as shown in the browser. If you receive the following error, it may indicate the browser is using a form that is unreachable to the backend services (e.g. a hostname). Re-enter the address as an IP address and try again. 169 MCS 2.3 Installation and Configuration Guide Bus Error If a “failed to query bus service” error appears, check that the ACS bus is running in a command shell. Errors in Zone Configuration An exclamation point next to a zone indicates incorrect configuration. The following table presents typical configuration error messages: Message Explanation The zone does not exist in the UMS. Zone is present in the BUS, but not in the UMS. The zone exists in UMS but is not linked. Zone is present in the UMS, but not in the BUS. Some links are missing The zone is missing one or more links to other zones. Errors During Setup If any stage of the setup fails, all the subsequent steps are skipped. In this case, the problem most likely cannot be fixed through the UI, and must be resolved at the command-line. 170 MCS 2.3 Installation and Configuration Guide Dismantling a Multi-Zone Environment When a multi-zone environment is no longer required, it can be dismantled. Dismantling a multizone environment removes all roles for multi-zone users (login credentials remain). If you later use the same user names on independent systems, you need to manually re-assign the roles on each system. To dismantle the multi-zone: 1. Log in to MediaCentral UX in the master zone as the Administrator user. 2. Select System Settings from the Layout selector and Zones in the Settings pane. 3. For each slave zone, select the zone and click the Remove Zone button. The Zone Details dialog appears for the slave zone. 4. In the Zone Details dialog, enter the following information: Master Zone Access: • Root Username and Root Password: The root user credentials for the master zone MCS server. Database Replication: • Node URL: This field is completed for you. This is the IP address of the MediaCentral instance/cluster in the slave zone. • Root Username and Root Password: This is the root user of the slave zone. Zone Registration: • Zone Name: This field is completed for you. This is the name of the slave zone (e.g. Slave_Zone). • UMS Password: Administrator password for the slave zone UMS database (e.g. Avid123). 171 MCS 2.3 Installation and Configuration Guide 5. Click the Unregister button. A dialog appears showing progress of the operations related to slave zone deregistration. 6. Repeat for any other slave zones you wish to add. Note: Any users logged into the slave zone will be disconnected at this time as services are restarted on the slave zone. 7. Once deregistration of the slave zone(s) is complete, select the master zone and click the Remove Zone button. The Zone Details dialog appears for the master zone. 8. Enter the master zone UMS administrator password (e.g. Avid123), then click the Unregister button. A dialog appears showing progress of the operations related to the de-registration. Note: Any users logged into the master zone will be disconnected at this time as services are restarted on the master zone. 172 MCS 2.3 Installation and Configuration Guide A PPENDICES 173 MCS 2.3 Installation and Configuration Guide Appendix A: Overview The purpose of this Appendix is to provide additional information and detail on topics included in the main body of the Installation Guide. The following table describes the topics covered in this Appendix. Topic Enabling the Player Demonstration Web Page Copying Software to the MCS Server Installing MCS on Non-HP / Dell Hardware for Interplay MAM Working with the Dell RAID Controller HP DL360p Gen8 Card Placement Contents of the MCS Installation Package Enabling Trusted Certificates Determining the Installed MCS Version Using SNMP Monitoring on the MCPS Server Log Cycling Retrieving MCS Logs Verifying Cache Directory Permissions Monitoring the AAF Generator Service Monitoring Services and Resources Backing up and Restoring the MCS Database Verifying the ISIS Mount Reconfiguring the ISIS Connection(s) Unicast Support in Clustering Reconfiguring MediaCentral Settings in a Cluster Shutting Down or Rebooting a MediaCentral Cluster Identifying the Master, Slave and Load-Balancing Nodes Monitoring MCS High-Availability Monitoring Load Balancing Changing the Cluster Administrator Email Address Taking a Cluster Node Off-Line Temporarily Permanently Removing a Node from a Cluster Adding a New Node to a Cluster Port Requirements 174 MCS 2.3 Installation and Configuration Guide Enabling the Player Demonstration Web Page The player demonstration web page (http:// /player/index.html) is a powerful tool for verification and troubleshooting. However, since it is accessible by way of an unrestricted URL, it is not installed by default (as of ICS 1.6). Note: The player demonstration web page is accessible by way of an unrestricted URL. This may be considered a security concern at customer sites. Moving or renaming its index.html file will prevent loading of the page. When not in use, move the player demonstration index.html file to a folder not accessible through http, such as the root user home directory (/root). The root user home directory is visible only to the root user. This is not to be confused with the root directory (/), which is visible to all users. To install/uninstall the player demonstration web page: 1. Log in to the master node as root. For help identifying the master node, see Identifying the Master, Slave and Load-Balancing Nodes on page 198. 2. Determine the name of the maxcut-devel RPM file containing the player demonstration web page: ls /opt/avid/Packages/ 3. Manually install the maxcut-devel RPM: rpm -ivh /opt/avid/Packages/maxcut-devel- .x86_64.rpm Recall that tapping the tab key invokes the Linux autocomplete functionality and ensures accuracy when typing long file names. Some feedback appears indicating the success of the installation. 4. To verify the package has been installed: rpm -qa | grep max 5. Log in to the slave node as root and repeat the process. 6. To launch the player demo web page by opening a browser and navigating to the following URL: http:// /player/index.html Where is the host name or FQDN of the node where you installed the player demonstration page. For a cluster, enter the virtual host name of the cluster instead. 7. To erase/remove the package (should you wish to uninstall): rpm –e maxcut-devel To move the player demonstration web page to a secure location: mv /var/www/html/player/index.html /root 175 MCS 2.3 Installation and Configuration Guide Copying Software to the MCS Server At various times during the upgrade, you will need to copy software to the MCS server. This task can be performed using one of two methods: Using a Windows system and a SFTP tool such as WinSCP Connecting a USB drive directly to the server While the SFTP method may be preferred for ease of access, the USB method may be required for some operations such as backing-up MCS files during a system upgrade. Copying Software Using WinSCP 1. Download and install the WinSCP software on a Windows system that has network access to the MCS server. The WinSCP software can be found at: http://winscp.net. 2. Launch WinSCP. 3. Enter the Host name (or IP address) of your server, User name (root), and Password. 4. Click Login. 5. The following warning message is displayed: “Continue connecting and add host key to the cache?” Click Yes. The WinSCP interface is displayed. The left pane represents your source Windows system. The right pane represents your MCS server. 6. Navigate to the location of the downloaded MCS installation files in the left pane. 7. Navigate to the /media folder on the MCS server in the right pane. 8. Right-click in the right pane and select New>Directory. 9. In the “New folder name” field, type installers and click OK. 10. Double-click on the new installers folder in the right pane. 11. Drag and drop the files or folders you wish to copy from the left pane to the right. Depending on your WinSCP settings, you might see a dialog box asking if you want to copy the files to the remote directory. Click Copy. 12. After all desired files or folders have been copied, close WinSCP. 176 MCS 2.3 Installation and Configuration Guide Copying Software Using a USB Drive For simply mounting and unmounting a USB drive, follow the process below and eliminate steps 7 and 8. 1. Insert the USB drive into the MCS server. 2. Verify the name of the device: dmesg Information for the USB drive will appear near the end of the output, near the list of SCSI devices. The name of the USB drive is found inside square brackets (for example, sdc). This is the name you use to mount the drive. 3. If needed, create a mount point for the USB drive: mkdir /media/usb 4. Mount the USB drive at the mount point you just created: mount /dev/sdc1 /media/usb Note the name of the USB drive, sdc (in this case) takes a 1 (one) in the mount command. This simply indicates a partition exists on the drive. When the USB drive was formatted, the partition was created. The USB drive is now mounted and available for use. 5. Verify the USB drive has been mounted: df -h Information is displayed about all mounted filesystems and devices, and should include information about the USB drive, similar to the following (other output has been omitted, for clarity): Filesystem Size Used Avail Use% Mounted on /dev/sdc1 7.5G 5.3G 2.2G 71% /media/usb 6. To change to the mount point: cd media/usb 7. If needed, create a directory for the installer packages: mkdir /media/installers 8. Copy files to the MCS server: For a single file: cp filename /media/installers For a folder: cp -R foldername /media/installers 9. Once you have finished copying all necessary files, unmount the USB drive. cd Note: In Linux the “cd” command without any arguments takes you directly to the user’s home directory. If you are logged in as root, it takes you to the /root directory. RHEL will not unmount the USB drive if it is the current active directory. 177 MCS 2.3 Installation and Configuration Guide umount /media/usb If you receive an error message that the USB device is busy, it typically indicates the Linux ISO on the USB drive was auto-mounted. Verify what is mounted using the df -h command or the mount command, or both. Then dismount the Linux ISO first, followed by the USB device: umount /sysinstall umount /media/usb Remove the USB drive from the server. Caution: Once you have copied the necessary software, make sure you unmount and remove the USB drive from the server. If you re-boot with the server with the USB drive still in place, RHEL will be re-installed and all your work will be lost. 178 MCS 2.3 Installation and Configuration Guide Installing MCS on Non-HP / Dell Hardware for Interplay MAM MCS supports MediaCentral and MediaCentral Cloud on HP and Dell hardware only. Therefore, this section does not pertain to those deployments. Installing MCS on non-HP or Dell hardware is only supported for Interplay MAM deployments. For the most part the steps provided in the main body of this guide for installing and configuring MCS on HP and Dell servers are easily generalized to other hardware. The primary difference is the use of a RHEL “kickstart” file. A kickstart file (ks.cfg) is a Linux convenience that speeds up installation by automatically answering some questions for hardware that is known in advance. The express installation of RHEL and MCS using a USB drive should not be followed on installations not using HP or Dell hardware. RHEL and MCS are installed in separate steps because there is no guarantee that the supplied kickstart file will work on other hardware. However, you can examine its contents and mimic them during a manual installation, or create a kickstart file for your own hardware. As previously stated, the kickstart file is a convenience and the creation of a kickstart file is not required. As of the ICS 1.4 release, three partitions are created on the (mirrored) system drive: The first is the boot partition (/boot). The second is the DRBD (Distributed Replicated Block Device) storage system partition. In a clustered configuration, MCS uses DRBD to replicate its PostgreSQL database. The third is the system partition (/). On HP and Dell hardware, the kickstart file on the MCS Installation USB Drive creates the second partition on the OS drive automatically. On other servers this partition would need to be created manually. After the second partition has been created the steps for setting up DRBD are the same as the HP / Dell process. Note: The DRBD partition on the system drive is required only for cluster deployments. However, it is recommended you create it even for a single MCS server deployment, to keep open the possibility of clustering. This process will require a RHEL DVD or dvd.iso. Log in to your Red Hat Network account and download the DVD image (.iso) file or purchase a DVD. Either format can be used for the MCS installation. Note: At the time of this document’s publication, the RHEL 6.5 ISOs were available by choosing Red Hat Enterprise Linux Server from the Red Hat Product Downloads page. Specify Red Hat Enterprise Linux Server (product variant), 6.5 (version) and x86_64 (architecture). Download the Binary DVD (rhel-server-6.5-x86_64-dvd.iso). 179 MCS 2.3 Installation and Configuration Guide Non-HP / Dell Installation Notes The following notes pertain to the main installation steps for non-HP hardware: 1. Set Up the Server Hardware a. Create a RAID 1 (mirror) for the system disk using the hardware BIOS utilities. b. If possible, set the system clock before installing RHEL. Otherwise, set the clock at the appropriate stage in the RHEL installation process. 2. Install RHEL manually. a. Select BASIC SERVER during the RHEL installation process. b. When prompted to create storage, create two partitions on the OS drive. One partition is for RHEL. The other one is used by DRBD. The DRBD partition should be 20GB in size. Note: Some MCS software components depend on the language for RHEL being set to English. Please select English as the language of installation. Do not change the input language afterwards. 3. Mount the RHEL Installer You will need to mount the physical DVD or DVD.iso to the /sysinstall directory. This is where the MCS install script looks for it. If you have physical RHEL DVD media: mount /dev/sdx /sysinstall In the above command, substitute the optical drive device name for sdx (e.g. sr0) Note: RHEL will automatically create an alias for the optical drive on /CDROM. Thus the following mount command can also be used: mount /CDROM /sysinstall If you have a RHEL .iso file: a. Create a directory on the server where you can copy the .iso. Example: mkdir /media/installers Note: If needed, see Copying Software to the MCS Server for instructions for mounting a USB drive. b. Copy the .iso to the newly created folder. cp /path/rhel-server-6.5-x86_64-dvd.iso /media/installers c. Mount the .iso mount –t iso9660 –o loop /media/installers/rhel-server6.5-x86_64-dvd.iso /sysinstall In the above command, “/media/installers” is used as an example. Substitute “/media/installers” with the directory you created for the .iso. 180 MCS 2.3 Installation and Configuration Guide 4. Install MCS. a. Unpack the MCS installer file: tar –zxovf MediCentral_Services_ .tar.gz b. Change directories to the MediaCentral_Services_ folder and run the installation script: ./install.sh 5. Once the installation is complete, follow the instructions in the body of this guide to Set up the cluster (optional), configure MCS for MAM (if applicable), etc., as instructed in the main body of this guide. 181 MCS 2.3 Installation and Configuration Guide Working with the Dell RAID Controller This section provides information on working with the Dell R620 / R630 RAID controller. The installation process assumes that the server shipped with preconfigured RAID 1 and RAID 5 arrays. If that is not the case, this information can be used to create the RAID sets. Creating the RAIDs 1. From the Virtual Disk Management menu, select Create Virtual Disk. If you just deleted the disk, this item is grayed-out. Go up one level in the menu system, and then return to the Virtual Disk Management page. 2. From the Create Virtual Disk page select Select Physical Disks. 3. Put check marks in the appropriate Physical Disk boxes. a. For the RAID 1 (system disk) this should be 00:01:00 and 00:01:01 b. For the RAID 5 (optional cache disk) this should be 00:01:02 through 00:01:07. 4. Select Apply Changes. A confirmation screen indicates success. 5. From the Create Virtual Disk Page, select Create Virtual Disk. You may need to scroll down the page to see the link. 6. From the Warning page, confirm you selection and select Yes. A confirmation screen indicates success. 7. Return to the Virtual Disk Management page and select View Disk Group Properties to view your changes. a. You should see a Virtual Disk 0 (the RAID 1) and a Virtual Disk 1 (the RAID 5). 8. Return to the Integrated RAID Controller Configuration Utility page. 9. From the Integrated RAID Controller Configuration Utility menu choose Controller Management. 10. From the Controller Management menu choose Change Controller Properties. 11. Verify that the Virtual Disk 0 (the RAID 1) is selected in Set Bootable Device. If not, select it and apply your changes. Once you install RHEL and MCS, you want the server to boot from the RAID 1. 12. Exit the RAID configuration utility and return to the System Setup menu. 182 MCS 2.3 Installation and Configuration Guide Deleting the RAIDs If necessary, it is possible to delete the RAID sets from within the RAID controller. 1. From the Virtual Disk Management menu select Select Virtual Disk Operations. 2. Select the virtual disk of interest (the RAID 1 or RAID 5) from the drop-down menu 3. Select Delete Virtual Disk. 4. Confirm your action. The menu indicates the success of the operation. HP DL360p Gen8 Card Placement Connecting to non-ISIS Proxy Storage Interplay MAM deployments where browse proxies reside on non-ISIS storage do not require additional NIC cards. They make use of the Ethernet ports built in to the HP server. Visually verify that one of the built-in ports is connected to the network. For a 10GigE connection to non-ISIS storage, use a 10GigE NIC of your choosing. Note: If MAM browse proxies reside on an ISIS, the connection to the ISIS must be over a Zone 1, Zone 2, or Zone 3 (recommended) connection, using a GigE or 10GigE network interface. HP DL360 Gen8 backplane (showing built-in Ethernet ports): Built-in Ethernet Ports Note: This applies to Interplay MAM deployments only. 183 MCS 2.3 Installation and Configuration Guide Connecting to ISIS Proxy Storage The HP DL360 G8 has a full height PCI slot in the upper left corner. Use this slot for either the Myricom 10GigE or the HP NC365T 4-port GigE NIC. The “built-in” Ethernet ports can also be used, if the server is provisioned with the HP 366FLR 4-port GigE NIC.

The ZIP file contains the following: Item Description MediaCentral_Services _ _Linux.tar.gz The MCS Server Installation package. This compressed tar file contains numerous files, including the following useful shell script: ics_version.sh It outputs version/build information for the following processes: • UMS - User Management Service • ICPS - MediaCentral Playback Services • ICPS Manager - MediaCentral Playback Services Manager (playerto-server connection manager) • ACS - Avid Common Services bus (“the bus”) • System ID: An 11-digit number used in support calls that you enter when configuring MediaCentral • ICS Installer - MediaCentral installer The MediaCentral version information is also available in the user interface in the Home -> About box. Once MCS is installed, a symlink is created and you can simply type the following to execute the script: ics_version install.sh The installation script, for upgrades and installations. iso2usb.exe iso2usb.patch iso2usb_LICENSE.html iso2usb_README.rtf ks.cfg ks_upgrade.cfg Used in creating the MCS installation MCS Installation USB Drive. system-backup.sh Prepares for an upgrade by backing up important data, including system settings, network settings, the Jetty keystore and application.properties file, and the UMS database. The Avid-supplied kickstart files for fresh installations and for upgrade installations. 185 MCS 2.3 Installation and Configuration Guide Enabling Trusted Certificates For security, MediaCentral uses the Secure Sockets Layer (SSL) for its server-to-browser connections. This is indicated by https:// in the browser address bar, rather than the usual http://. (Some browsers also show a locked padlock icon for an SSL connection.) SSL enables the secure transmission of information between web servers and web browsers. For more information on configuring SSL certificates, see the Avid Knowledge Base: http://avid.force.com/pkb/articles/en_US/how_to/SSL-Certificates-for-server-to-browser-connections Determining the Installed MCS Version The version and build numbers of the MCS installation can be verified with the following command: ics_version Service version numbers are returned as follows: UMS Version: 2.3.x.x ICPS Version: 2.3.x.x ICPS manager Version: 2.3.x.x ACS Version: 2.3.x.x System ID: "xxxxxxxxxxx" ICS installer: 2.3 (Build xx) Created on Note: The System ID is an 11-digit number you entered when configuring MediaCentral. Note: For precise version numbers for this release, see the Avid MediaCentral Platform Services ReadMe. Using SNMP Monitoring on the MCPS Server The Avid System Monitor application and MCS server can be configured to collect information from the MCS server. This allows you to monitor the status of mandatory MCS services and display graphs for activities such as CPU usage, network usage, and system memory usage. The following items are graphed over time in the Avid System Monitor web page interface: • Average CPU load • Number of CPU interrupts per second • System uptime • Swap space (disk space reserved for memory when RAM is fully loaded) • System memory usage • CPU usage Contact your Avid representative for information about Avid System Monitor. A qualified Avid support representative can upgrade an Avid System Monitor system to work with MCS. 186 MCS 2.3 Installation and Configuration Guide Log Cycling Like other Linux logs, the MCS server logs are stored under the /var/log directory, in /var/log/avid. Logs are automatically rotated on a daily basis as specified in /etc/logrotate.conf. Retrieving MCS Logs As you use MediaCentral you may encounter issues for which you wish to gather additional information. The simplest way to retrieve logs residing on a Linux machine is using an application that supports SCP/SFTP such as WinSCP (Windows) or muCommander (MacOS). To retrieve MCS logs using an SCP/SFTP client: 1. Launch the SCP/SFTP client (WinSCP shown) and enter the session information. • Hostname: The host name of the MCS server you want to gather logs from. • User name: root • Password: _ Note: Please contact your Avid representative for the default root password. 2. Once connected, navigate to the directory where the logs are stored: /var/log/avid 3. Use the SCP/SFTP client’s built-in functionality to retrieve the logs. Some logs can be quite large and may take longer to transfer. If you encounter any issues on your MCS system, contact Avid Customer Care for assistance. 187 MCS 2.3 Installation and Configuration Guide Verifying Cache Directory Permissions As part of the installation (or upgrading) process, you created a number of cache directories, changing ownership and setting their permissions. In this section, you verify the permissions are set correctly. Note: This procedure is only necessary for a cluster deployment. Do not use this procedure for a single node deployment. Some directories may not be present, as they are created automatically in a running system. Adjust the steps accordingly. To verify cache directory permissions: 1. Verify the ownership and permissions for of all cache directories: ls -la /cache Output similar to the following ought to be presented: drwxrwxrwx drwxr-xr-x drwxrwsrwx drwxrwsrwx drwxrwxrwx drwxrwxrwx drwxrwxrwx 9 33 2 5 55 2 9 maxmin root maxmin maxmin root root root maxmin root maxmin maxmin root root root 4096 4096 4096 4096 4096 4096 4096 Nov Nov Nov Nov Nov Nov Nov 4 4 4 4 4 4 4 10:13 13:34 20:04 20:03 13:50 10:04 14:05 . .. download fl_cache mob-fetch render spooler Note that in the output above the dot (“.”) directory represents the current directory, that is, /cache. Note that some directories might not exist yet, as explained in the following table: Directory Description /cache/fl_cache Automatically created and assigned maxmin ownership by MCS processes only after specific media types have been accessed. /cache/download As above. /cache/render Automatically created by MCS processes with first multicam playback. For a complete description of all cache directories, see the MediaCentral Platform Services Concepts and Clustering Guide. 2. The following directories must be owned by user maxmin: /cache /cache/download /cache/fl_cache 3. The following directories must have the SGID special bit set: /cache/download /cache/fl_cache 4. If the ownership and permissions are not set correctly, refer to the instructions in “Making the RHEL Cache Directories” on page 127. 188 MCS 2.3 Installation and Configuration Guide Monitoring the AAF Generator Service The AAF Generator service (avid-aaf-gen) is responsible for saving sequences. To reduce the possibility of bottlenecks when many users attempt to save sequences at the same time, multiple instances of the service run simultaneously (by default, five). As a result, MediaCentral has the ability to save multiple sequences concurrently, significantly reducing overall wait-times under heavy load. In a cluster deployment, this service is installed and running on all nodes. However, it is only involved in saving sequences on the node where the IPC core service (avid-interplay-central) is currently running. The service is not managed by Pacemaker. It is therefore important to regularly verify its status. If one or more instances of it have failed, restart the service. An instance can fail, for example, if an invalid AAF is used within a sequence. If all instances fail, responsibility for saving transfers to the MediaCentral core service (avid-interplay-central), and bottlenecks can arise. Logs are stored in /var/log/avid/avid-aaf-gen/log_xxx. To verify the status and/or stop the AAF Generator service: 1. Log in to both the master and slave nodes as root. Though the AAF Generator service is active in saving sequences only on the master node, you should verify its status on the slave node too, to prepare for any failover. 2. Verify the status of the AAF Generator service: service avid-aaf-gen status The system outputs the status of each instance, similar to the following: avid-aaf-gen_1 avid-aaf-gen_2 avid-aaf-gen_3 avid-aaf-gen_4 avid-aaf-gen_5 process process process process process is is is is is running running running running running [ [ [ [ [ OK OK OK OK OK ] ] ] ] ] An error would look like this: avid-aaf-gen_1 process is not running [WARNING] 3. In the event of an error, restart the service as follows: service avid-aaf-gen restart Output similar to the following indicates the service has restarted correctly: Starting Starting Starting Starting Starting process process process process process avid-aaf-gen_1 avid-aaf-gen_2 avid-aaf-gen_3 avid-aaf-gen_4 avid-aaf-gen_5 - Stat: Stat: Stat: Stat: Stat: 0 0 0 0 0 [ [ [ [ [ OK OK OK OK OK ] ] ] ] ] 189 MCS 2.3 Installation and Configuration Guide 4. If you need to stop the service this must be done in two steps. First, configure 0 instances of the service (there are 5 by default): echo 0 > /opt/avid/avid-aaf-gen/DEFAULT_NUM_PROCESSES 5. With zero instances configured, stop the service: service avid-aaf-gen-stop To restart the service, reset the number of instances to the default (5) then restart it in the usual way. Monitoring Services and Resources Resources are collections of services grouped together for oversight by Pacemaker. Pacemaker sees and manages resources, not individual services. The state of services can be verified by typing the following command at the command line: service status If the service is not active, it can be restarted by using the following command: service restart The state of a cluster resource can be verified by typing the following command: crm resource status 190 MCS 2.3 Installation and Configuration Guide Backing up and Restoring the MCS Database You may recall that the system-backup script, discussed in the Backing up the MCS System Settings and the MCS Database section of this document, calls the avid-db command as part of its system setting backup process. The MCS database is automatically backed up by the same avid-db utiliy on a daily basis. If desired the utility can run manually to back up and restore the database (plus perform other operations) at any time. The avid-db command has the following format: /opt/avid/bin/avid-db [ ... ] For example, to back up the contents of the MCS database to /opt/avid/share/avid/db/dumps: /opt/avid/bin/avid-db -–dump-base=/opt/avid/share/avid/db/dumps dumpall For a list of all the parameters and arguments, issue the following: /opt/avid/bin/avid-db help Note: Restoring the MCS database in cluster has special requirements. Due to the automatic restarting of halted services in a cluster, do not use the avid-db restore command by itself. Follow the procedure as outlined below. To restore the MCS database in a cluster: 1. Log in to the master and slave nodes as root. For help identifying the node, see Identifying the Master, Slave and Load-Balancing Nodes on page 198. 2. Stop pacemaker on both nodes: service pacemaker stop 3. Start DRBD on both nodes: service drbd start 4. Make the master node the DRBD primary (on the master node): drbdadm primary r0 5. Mount the DRBD drive on the master node: mount /dev/drbd1 /mnt/drbd 6. Start the PostgreSQL database on the master node: service postgresql-9.1 start 7. Restore the MCS database on the master node: /opt/avid/bin/avid-db --drop-db="no" restoreall Once the MCS database has been restored, begin handing control back to pacemaker in the steps below. 191 MCS 2.3 Installation and Configuration Guide 8. Stop PostgreSQL on the master node: service postgresql-9.1 stop 9. Unmount the DRBD drive on the master node: umount /mnt/drbd 10. Stop DRBD on both nodes: service drbd stop 11. Restart Pacemaker (which restarts all needed services) on both nodes, master node first, slave node second: service pacemaker start 192 MCS 2.3 Installation and Configuration Guide Verifying the ISIS Mount The validity of the ISIS mount is initially authenticated during the configuration procedure. In that procedure, the Status of the ISIS connection changes from “Disconnected” to “Connected”. However, it is possible to verify the ISIS mounts using various command line tools which can be useful for troubleshooting. Examples of such commands are: • service avid-isis status • mount -t fuse.avidfos • df -h To verify the ISIS mount(s): 1. Verify the status of the avid-isis service: service avid-isis status The system responds with output similar to the following: AVID Service: isis fuse_avidfos (pid 2302) is running...[ OK ] 2. Use the Linux mount command to display all mounted filesystems of type fuse.avidfos (the ISIS filesystem): mount -t fuse.avidfos The system responds with output showing the ISIS mounts, similar to the following: wavd-isis on /mnt/ICS_Avid_Isis/wavd-isis type fuse.avidfos (rw,nosuid,nodev,allow_other,default_permissions) The output above indicates an ISIS called wavd-isis mounted at /isis/wavd-isis. “Fuse” is the RHEL filesystem type reserved for third-party filesystems. 3. The Linux df command displays disk usage information for all the mounted filesystems: df -h The system responds with output similar to the following: Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_icps-lv_cache 527G 6.3G 494G 2% / tmpfs 24G 0 24G 0% /dev/shm /dev/sda1 485M 33M 428M 8% /boot wavd-isis 15T 5.7T 8.9T 40% /mnt/ICS_Avid_Isis/wavd-isis /dev/sdb1 7.3G 5.5G 1.9G 75% /media/usb 4. Finally, explore the mounted ISIS and its workspaces by navigating it as you would any Linux filesystem. For example, for the sample output shown above, to view the workspaces available to the MCPS player, list the contents of the mounted ISIS: ls /mnt/ICS_Avid_Isis/wavd-isis 193 MCS 2.3 Installation and Configuration Guide Reconfiguring the ISIS Connection(s) When you set up MCS for the first time you configure a network interface to be used for playback of video assets. For a MediaCentral UX and/or Media Composer UX deployment, for example, you configure a GigE or 10GigE connection to the ISIS. If at a later date you decide to change the network interface, this section provides the instructions. To reconfigure the ISIS Connection(s): 1. Install the new card. See Network Interface Cards and Network Connections on page 13. 2. Verify the NIC interface names using the RHEL Network Configuration tool. See Identifying NIC Interfaces and Connecting the Network Cable on page 66. 3. If running an HP server, swap the NIC interface names so the new card owns port eth0 by editing the 70-persistent-net.rules file. See (HP Only) Swapping NIC Interface Names on page 67. 4. If running an HP server, remove the MAC address hardware references for the swapped ports from the corresponding ifcfg-ethX files and reboot. See (HP Only) Removing the MAC Address Hardware References on page 69. 5. Log in to MediaCentral UX with administrator privileges and update the ISIS connection in the Playback Service System Settings to match the new connection speed. For example, change it from “1 Gb Connection” to “10 Gb Connection”. See Playback Service Settings on page 96. 194 MCS 2.3 Installation and Configuration Guide Unicast Support in Clustering MCS clustering supports both unicast and multicast communication protocols. The default configuration, as set up by the cluster installation script (and covered in the body of this guide) uses multicast. In facilities where the routers do not support multicast (i.e. are not multicast enabled), configuring the cluster for unicast communication is an alternative. This process can also be used for new installations and for systems that already have a functional cluster configured for multicast and wish to convert to unicast communication. Note: If you are converting an existing multicast cluster to unicast communication, skip Step 1 of the following process. Configuring a cluster for unicast requires altering the contents of the corosync configuration (corosync.conf) file. The following is an example of the default corosync configuration file using multicast: totem { version: 2 secauth: off threads: 0 interface { ringnumber: 0 bindnetaddr: 192.168.10.0 mcastaddr: 239.192.1.1 mcastport: 5405 } } The following is an example of an altered corosync configuration file using unicast: totem { version: 2 secauth: off threads: 0 interface { member { memberaddr: 192.168.10.51 } member { memberaddr: 192.168.10.52 } ringnumber: 0 bindnetaddr: 192.168.10.0 mcastport: 5405 } transport: udpu } Note the following changes in the altered file: • A “member{}” section for each node in the cluster has been added. • “mcastaddr: 239.192.1.1” has been removed. • A “transport: udpu” line has been added. 195 MCS 2.3 Installation and Configuration Guide Configuring Unicast Cluster Communication This process assumes that the following steps from the PART V: CLUSTERING section of this guide have already been completed: • Cluster Overview • Configuring the Player System Setting • Configuring DRBD 1. Run the following command on each node in the cluster: /opt/avid/cluster/bin/cluster setup-corosync --corosync-bindiface=interface --rabbitmq_master="master hostname" When using this command, reference the following: • • interface: Identifies the name of the primary network interface. In an HP server, this is generally “eth0”. In a Dell server, this is generally “em1” for 1 Gb connections or “p1p1” / “p2p1” for 10 Gb connections (depending on which slot the card 10 Gb card has been installed). For Interplay MAM configurations with port bonding, this is generally “bond0”. Quotes are not required in this command. master hostname: Specifies the (short) hostname of the Master node in the cluster (e.g. wavd-mcs01). This should be the same as the DRBD Master node specified in the drbd_setup process. Quotes are required in this command Note: The body of this guide instructs you to run this command on the master node only. In this process, you will run the command on all nodes. 2. Stop the cluster services on all load-balancing nodes: service pacemaker stop && service corosync stop 3. Stop the cluster services on the slave node: service pacemaker stop && service corosync stop 4. Once the cluster services have been stopped on the slave node, stop the services on the master node: Note: You can confirm the status of the slave and load-balancing nodes through the Cluster Resource Monitor, crm_mon. All non-master nodes should report as “OFFLINE”. service pacemaker stop && service corosync stop 5. Using the example above as a guide, edit the corosync configuration file: vi /etc/corosync/corosync.conf • Remove mcastaddr from the file (leave mcastport). • Add the new transport (that indicates unicast): udpu. • Create a member{} section for each node in the cluster, following the example, but replacing the values for memberaddr with the IP addresses of your own cluster nodes. 196 MCS 2.3 Installation and Configuration Guide 6. Restart the cluster services on the nodes in the reverse order that you stopped them (master node first, then slave, then load-balancing nodes): service corosync start && service pacemaker start Prior to starting the services on the slave and load-balancing nodes, use the Cluster Resource Monitor, crm_mon, to verify that all resources have started on the master node. 7. Once you have completed the above instructions on each node in the cluster, run the setupcluster command on the DRBD master node only, following the instructions in the body of this guide. The most commonly used form of the setup-cluster command is provided below (for reference): /opt/avid/cluster/bin/cluster setup-cluster --cluster_ip=" " --pingable_ip=" " --cluster_ip_iface=" ” --admin_email=" " --drbd_exclude=" " See “Starting the Cluster Services on the Master Node” for details (and the appropriate form of the setup-cluster command). 8. Restart the following services on each node so that they register correctly on the newly created instance of the message bus: service avid-acs-messenger restart service avid-aaf-gen restart 9. Launch the Cluster Resource Manager to verify that the cluster is aware of all nodes and that all services are running normally. crm_mon -f Reconfiguring MediaCentral Settings in a Cluster If you reconfigure any MediaCentral System Settings (e.g. adding/removing an ISIS system), the new settings are retained by the master node only. Non-master nodes must be updated manually. On each non-master node, log in as root and run the following command: service avid-all reconfigure Shutting Down or Rebooting a MediaCentral Cluster For a detailed process, see the Avid Knowledge Base: http://avid.force.com/pkb/articles/en_US/how_to/Shutdown-or-reboot-procedure-for-aMediaCentral-cluster 197 MCS 2.3 Installation and Configuration Guide Identifying the Master, Slave and Load-Balancing Nodes Recall that there are three types of nodes in a cluster: master, slave, and load-balancing. The master “owns” the cluster’s virtual IP address. The slave assumes the role of master in the event of a failover. Any extra nodes play a load-balancing role, but can never take on the role of master. To identify the master, slave, and load-balancing nodes: 5. Identify the master node of the cluster. Log into any machine in the cluster as root and type: crm_mon 6. In the output of that command, look for the line containing “AvidClusterIP”—this service runs on the master server. For example, if the crm_mon command output contains the line: AvidClusterIP (ocf::heartbeat:IPaddr2): Started wavd-mcs01 …the master server is wavd-mcs01. 7. To identify the slave, look for the line containing “Master/Slave Set”. For example, if the crm_mon command output contains the lines: Master/Slave Set: ms_drbd_postgres [drbd_postgres] Masters: [ wavd-mcs01 ] Slaves: [ wavd-mcs02 ] …the slave server is wavd-mcs02. 8. To identify the load-balancing nodes, look for the line containing “Clone Set”. For example, if the crm_mon command output contains the lines: Clone Set: AvidAllEverywhere [AvidAll] Started: [ wavd-mcs01 wavd-mcs02 wavd-mcs03 ] …the extra server in this case is wavd-mcs03. 198 MCS 2.3 Installation and Configuration Guide Monitoring MCS High-Availability If you have configured a highly-available and load-balanced MCS cluster, see the following commands to monitor the cluster for problems and if necessary, resolve them. If the following procedure does not resolve problems with the MCS cluster, please contact an Avid representative. To monitor the status of the cluster: Enter the following command as root. crm_mon -f This returns the status of services on all nodes. Error messages may appear. A properly running cluster of 2 nodes named wavd-mcs01 and wavd-m02 will return something like the following: Last updated: Wed Jun 25 13:11:10 2014 Last change: Thu Jun 19 11:42:05 2014 via crmd on wavd-mcs01 Current DC: wavd-mcs01 - partition with quorum 2 Nodes configured 18 Resources configured Online: [ wavd-mcs01 wavd-mcs02 ] Clone Set: AvidConnectivityMonEverywhere [AvidConnectivityMon] Started: [ wavd-mcs01 wavd-mcs02 ] AvidClusterMon (lsb:avid-monitor): Started wavd-mcs01 MongoDB (lsb:mongod): Started wavd-mcs01 Redis (lsb:redis): Started wavd-mcs01 Resource Group: postgres postgres_fs (ocf::heartbeat:Filesystem): Started wavd-mcs01 AvidClusterIP (ocf::heartbeat:IPaddr2): Started wavd-mcs01 pgsqlDB (ocf::avid:pgsql_Avid): Started wavd-mcs01 Master/Slave Set: ms_drbd_postgres [drbd_postgres] Masters: [ wavd-mcs01 ] Slaves: [ wavd-mcs02 ] Clone Set: AvidAllEverywhere [AvidAll] Started: [ wavd-mcs01 wavd-mcs02 ] AvidIPC (lsb:avid-interplay-central): Started wavd-mcs01 AvidUMS (lsb:avid-ums): Started wavd-mcs01 AvidUSS (lsb:avid-uss): Started wavd-mcs01 AvidACS (lsb:avid-acs-ctrl-core): Started wavd-mcs01 Clone Set: AvidICPSEverywhere [AvidICPS] Started: [ wavd-mcs01 wavd-mcs02 ] Migration summary: * Node wavd-mcs01: * Node wavd-mcs02: Note the line identifying the master node: • AvidClusterIP This is the node you will put into standby mode to observe failover (wavd-mcs01 in the above example). 199 MCS 2.3 Installation and Configuration Guide Note that the master node always runs the following services: • AvidIPC (avid-interplay-central) • AvidUMS (avid-ums) • AvidUSS (avid-uss) • AvidACS (avid-acs-ctrl-core) In the bullet list above, the actual service name, as it would appear at the Linux command line, is shown in parentheses. Note: The prefix lsb shown in the cluster resource monitor indicates the named service conforms to the Linux Standard Base project, meaning these services support standard Linux commands for scripts (e.g. start, stop, restart). • If you see errors in the crm_mon report about services not running, enter the following (as root): /opt/avid/cluster/bin/cluster rsc-start • If you see fail counts listed (in the Migration Summary area), reset them following the instructions found in the Testing Cluster Failover process. Monitoring Load Balancing Incoming playback requests are routed to the cluster’s virtual IP address, and then distributed evenly throughout the cluster. Load balancing is automatic, and supports many concurrent clients simultaneously. The load balancing daemon/service, xmd, runs multiple instances on each node in the cluster. Note: To monitor load balancing in an Interplay MAM deployment, a server hostname must be entered in the Player section of the MCPS settings. See Configuring MCS for Interplay MAM on page 107. To monitor load-balancing: 1. Sign in to MediaCentral using the default Administrator credentials (case-sensitive): • User name: Administrator 2. Select System Settings from the Layout selector. 3. In the Settings pane, click Load Balancer. The nodes involved in load balancing appear in the details pane. 200 MCS 2.3 Installation and Configuration Guide The following table explains the information: Service Description Node Name Host name of the load-balancing node. Click the plus (+) button to reveal details about a particular node, as explained below. Service The xmd service is the playback service responsible for delivering video from the MCS server to the player embedded in the web browser. User Reserved for future use. Host The IP address of the client machine (and end-user) to which video is being served. Session ID The session ID associated with the playback session. Session Start The time (MM.DD.YYYY HH:SS) at which the player embedded in the browser connected to the MCS server. Session End The time at which the session was terminated. IP The node’s IP address (e.g. XXX.XX.XX.XXX/32) Note that a /32 netmask indicates that point-to-point communication is used by the load balancing service. It does not reflect the facility netmask in use across the facility network. Added The time (MM.DD.YYYY HH) at which the node was added to the load-balancer. 4. The following table explains the possible actions you can take. Action Description Update Updates information (e.g. host, session ID, etc.) for all nodes registered for load balancing. Reset Flushes the database where nodes register for load balancing. Helpful if you have removed a node from the cluster, but it continues to appear in the list. Nodes capable of load balancing will self-register in a short time. delete Explicitly removes the named node from the load balancing database. This does not remove the node from the cluster. 201 MCS 2.3 Installation and Configuration Guide Changing the Cluster Administrator Email Address When you set up the cluster, you provided an administrator email address where the system sends emails related to cluster performance. You can change the email address (or add others) at any time using the Corosync-Pacemaker command-line interface for configuration and management, crm. For more information on the crm tool, type the following at the Linux prompt: man crm To change the cluster administrator email address: Note: Please be careful when editing the cluster configuration settings. Incorrect settings will break the cluster. 1. Load the crm configuration file into the Linux vi editor: crm configure edit Note: Due to a bug in the Cluster Resource Manager, “crm configure edit” must be entered on one line. Do not enter the Cluster Resource Manager in steps (that is crm -> configure -> edit). If you do, the changes are not saved. 2. Scroll to the bottom of the file, or jump to it directly (Shift-g). 3. Locate the line indicating the cluster administrator email address, for example: admin-email="email_A@temp.net" 4. Edit the admin-email string as desired, for example. admin-email="email_A@temp.net,email_B@temp.net" 5. Save and exit the vi session. Press and type: :wq The system responds by writing the updated configuration file to a temporary location and outputting an error message similar to the following: "/tmp/tmpjve4D9" 72L, 3258C written ERROR: rsc-options: attribute admin-email does not exist Do you still want to commit? 6. Type yes to commit your changes. 7. Verify the changes have been made by displaying the Cluster Resource Manager configuration information: crm configure show Look for the “admin-email” entry, near the bottom of the file. 8. Press Q to exit. 9. The new email address(es) are now active. 202 MCS 2.3 Installation and Configuration Guide Taking a Cluster Node Off-Line Temporarily If you need to take a node offline make sure to let your users know that playback may stop. In the best case, the client will automatically re-connect to one of the remaining available nodes, though it may take several seconds. In the worst case, the end-user be required to log in to MediaCentral again, in which case playback will be stopped. To take a cluster node off-line temporarily, log in as root on any node and issue the following command: crm node standby In the above command, replace with the name of the node to be brought off-line. Permanently Removing a Node from a Cluster Permanently removing a node from a cluster takes the following main steps: 1. Bring the cluster into maintenance mode 2. Unmount the GlusterFS volumes 3. Recreate the GlusterFS volumes, without the eliminated node 4. Reconfigure the cluster, and bring the cluster back up. Note: Even after performing the above steps, a “node offline” message may remain in the cluster monitoring tool (crm_mon). To eliminate the “ghost” node, delete node from the cluster using the following command: crm node delete 203 MCS 2.3 Installation and Configuration Guide Adding a New Node to a Cluster To add a node to an existing cluster, the cluster must be dismantled and rebuilt. The process consists of the following main steps: 1. 2. 3. 4. 5. Preparing the new node Bringing the cluster into maintenance mode Unmounting the GlusterFS volumes Recreating the GlusterFS volumes, including the new node Reconfiguring the cluster, including the new node and bring the cluster back up To prepare the new node: To prepare the new node, complete Parts I – III of this document. To bring the cluster into maintenance node: Put each node in the cluster into standby mode (maintenance mode) using the crm utility: crm node standby In the above command, replace < node name> with the name of each node, in turn. To unmount the GlusterFS volumes: In this step you dismantle GlusterFS (the Gluster filesystem). This must be done so Gluster will recognize the new node, later. If you leave traces of the old GlusterFS behind, gluster will refuse to integrate the new node. 1. On each server in the cluster, unmount the GlusterFS volumes from the Linux filesystem: umount /cache/download umount /cache/fl_cache 2. One any server in the cluster, stop the GlusterFS volumes: gluster volume stop gl-cache-dl gluster volume stop gl-cache-fl 3. One any server in the cluster, delete the GlusterFS volumes: gluster volume delete gl-cache-dl gluster volume delete gl-cache-fl 4. On each server in the cluster, remove the Linux extended attributes for the /cache directories: setfattr setfattr setfattr setfattr -x -x -x -x trusted.glusterfs.volume-id /cache/gluster/gluster_data_download trusted.glusterfs.volume-id /cache/gluster/gluster_data_fl_cache trusted.gfid /cache/gluster/gluster_data_download trusted.gfid /cache/gluster/gluster_data_fl_cache 5. Remove the hidden files used by Gluster: rm -rf /cache/gluster/gluster_data_download/.glusterfs rm -rf /cache/gluster/gluster_data_fl_cache/.glusterfs 204 MCS 2.3 Installation and Configuration Guide To re-create the GlusterFS filesystem and include the new node: In this step you set up Gluster from scratch, this time including the new node. For the most part, you can follow the instructions in Replicating the File Caches using GlusterFS on page 121 as they are written. Note the following points: 1. Install Gluster and create cache directories as instructed on the new server only. The other nodes already have Gluster and the cache directories. 2. Create the trusted storage pool as instructed. 3. Configure and start the GlusterFS volumes as instructed. 4. Mount the GlusterFS volumes in Linux as instructed. You will receive appropriate error messages for some steps, where the work has already been done on all but the new node (such as creating /cache subdirectories). Similarly, the filesystem table (/etc/fstab) does not need to be altered for the old nodes, just the new one. 5. Test the cache as instructed. 6. Ensure Gluster is on at boot for the new node. It is already set to be on at boot on the old nodes. To bring the cluster back up with the new node: In this step, you run the setup-cluster script on an existing master or slave node, as you did when originally setting up the cluster, excluding the new node from DRBD. Next, you join the new node to the cluster. 1. On either the master or slave node, run the setup-cluster script. Be sure to exclude the new node (and all other load-balancing-only nodes) from DRBD. 2. On the new node, run the setup-corosync script. Observe as the new node joins the cluster. 3. Bring the other nodes out of maintenance (standby) mode: crm node online Note the following points: • Do not set up DRBD again. It is already set up on the master-slave pair, and does not run on any other nodes. • The node where you run the setup-cluster script becomes the master, but it must be run on either the master or slave node from the old cluster. 205 MCS 2.3 Installation and Configuration Guide Port Requirements The following table lists the MCS port requirements for the client-side applications (the browserbased MediaCentral application and mobile applications). Ports 80 and 443 are required for the HTTP(S) traffic. In addition, the Adobe Flash Player (running inside the browser) requires ports 843 and 5000. For more information see the MCS Security Architecture and Analysis document. Component Port Protocol and Direction Usage MediaCentral Web application 80 TCP inbound MediaCentral Playback Services (MCPS) HTTP calls (file streaming from MCPS) 443 Secure TCP Inbound MediaCentral HTTPS calls (communication with MediaCentral server) 843 TCP Inbound Serving Flash Player socket policy files 5000 TCP Inbound Playback service (loading assets, serving JPEG images, and audio, etc.).

Service Name Port MediaCentral 80, 443 MCPS 843 (Flash), 80, 5000, 26000 MCS 8000 (optional Admin UI), 8183 (bus cluster info) ISIS 5000 – 5399 (UPD and TCP) RabbitMQ 5672 (AMQP), 15672 (Management UI/API) MongoDB 27017 PostgreSQL 5432 System 22, ICMP, 111, 24007, 24008, 24009-(24009 + number of bricks across all volumes for Gluster). If you will be using NFS, open additional ports 38465(38465 + number of Gluster servers). Some MAM configuration might require additional NFS ports (111, 2049 tcp & udp) or CIFS (137,138 udp and 137,139 tcp). Other filesystems will have to be checked individually (Isilon, Harmonic Omneon, etc.). 206 MCS 2.3 Installation and Configuration Guide Appendix B: Configuring Port Bonding for Interplay MAM In MAM deployments of MCS, port bonding improves playback performance when multiple clients are making requests of the MCS server simultaneously. With port bonding, more concurrent playback requests can be sustained by a single server, especially for file-based playback. Port bonding is only possible for Interplay MAM deployments. It does not apply to MediaCentral and/or Media Composer Cloud deployments. Verifying the Ethernet Ports In a port bonding configuration, two or more ports are grouped together. Before bonding the ports, identify the ports you wish to allocate using the RHEL set-up menus. To verify the Ethernet ports for port bonding: 1. Enter the RHEL set-up menus by typing setup at the command prompt: setup The setup screen appears. 2. From the Choose a Tool menu, select the Network Configuration option. Press Enter. 3. Choose the Device Configuration option. Press Enter. A list of network interface ports appears. 4. Identify the names of the ports you plan to bond together. Example: eth0 & eth1 5. Exit the set-up menus without making any changes by pressing Cancel and Quit. Configuring the Ports Port bonding requires that you modify the contents of the interface configuration files for each bonded ports and the creation of a new configuration file for the bonded interface. To configure port bonding for Interplay MAM: 1. Navigate to the directory containing the interface configuration files. cd /etc/sysconfig/network-scripts 2. List the directory contents to view the files. ls 3. Using the vi editor, open the interface configuration file for the first interface to be included in the port bond. Depending upon your server type, this could be ifcfg-eth0, ifcfg-em1, or other. In this process an HP “eth0” interface will be used as an example. vi ifcfg-eth0 207 MCS 2.3 Installation and Configuration Guide 4. When you open it for editing, the file should look something like this: DEVICE=eth0 NM_CONTROLLED=yes ONBOOT=yes DHCP_HOSTNAME=$HOSTNAME BOOTPROTO=static TYPE=Ethernet USERCTL=no PEERDNS=yes IPV6INIT=no • DEVICE=eth0 specifies the name of the physical Ethernet interface device. This line will be different for each device. It must correspond to the name of the file itself (e.g. ifcfg-eth0). • ONBOOT=yes must be set to “yes” so Linux brings up the port at boot time. 5. Add port bonding configuration information for the device by inserting the following line (shown in bold): DEVICE=eth0 NM_CONTROLLED=yes ONBOOT=yes MASTER=bond0 DHCP_HOSTNAME=$HOSTNAME BOOTPROTO=static TYPE=Ethernet USERCTL=no PEERDNS=yes IPV6INIT=no • MASTER=bond0 specifies the name of the port bonding interface. This must be the same in each network script file in the port bonded group. 6. Save and exit the vi session. Press and type: :wq 7. Perform the above steps for each interface to be included in the port bond (e.g. eth0, eth1, eth2, etc.) 8. Create a new port bonding network script file in the same directory. Use vi to create the file: vi ifcfg-bond0 Where “ifcfg-bond0” is the name of the port-bonding group. 208 MCS 2.3 Installation and Configuration Guide 9. Add the following lines to the newly created file: DEVICE=bond0 ONBOOT=yes BOOTPROTO=static USERCTL=no BONDING_OPTS="mode=0" IPADDR= NETMASK= GATEWAY= • DEVICE=bond0 specifies the name of the port bonding group interface. It must correspond to the name of the file itself. • BOOTPROTO=static lets you assign IP address of the device explicitly (recommended), or allow a local DHCP server to assign of the IP address device dynamically. Can be static (recommended) or dhcp (system assigned). • BONDING_OPTS="mode=0" specifies round-robin). • IPADDR and NETMASK entries are required if you are assigning a static IP address. • GATEWAY is required if you are routing outside of your primary subnet. specifies the type of port bonding (mode=0 10. Save and exit the vi session. Press and type: :wq 11. Restart the network service (as root): /etc/init.d/network restart 209 MCS 2.3 Installation and Configuration Guide Appendix C: Enabling MOS Active-X Plug-Ins This section includes steps to enable MOS Active-X Plug-Ins for: Chrome Internet Explorer (legacy) Note: As of MediaCentral v2.3, Internet Explorer is no longer a supported browser. This applies to all versions of Internet Explorer. Note: Active X plug-ins are not supported in the Safari browser. Enabling MediaCentral MOS Plug-Ins in Chrome MediaCentral provides support for MOS Active-X plug-ins. For example, Deko Select is a plug-in for a newsroom computer system’s interface that allows a user, such as a reporter, to drag and drop graphic templates directly into the story, as well as alter replaceable text or graphics in the selected template. You can also use the Avid Deko Select plug-in to add graphics to the video for a story sequence. Other plug-ins are available through third-party manufacturers. These plug-ins are specific to iNEWS workflows, and they are available only in Rundown and Story layouts. Note: The MCS installation program installs only the container needed for Active X controls. You need to install additional software as described in the following sections. Setting Up Your Browser The Chrome browser requires an extension that lets you use MOS plug-ins. The first time you sign in to MediaCentral, a dialog box asks if you want to use MOS plug-ins. • If you click yes, an installer is downloaded from the MediaCentral Services server. Allow pop-ups from the MediaCentral Services server if you are informed that a pop-up was blocked, and then refresh the page. Double-click the .exe file to install the program. After installation is complete, close Chrome and then reopen it for the extension to be accessible by MediaCentral. Recent Chrome versions disable third-party plug-ins. Make sure that Chrome Tools > Extensions displays Enabled next to the Avid ActiveX extension. • If you click no, and later want to use plug-ins, enable MOS as described below. The next time you sign in or refresh the application, a blank window opens and the installer is downloaded. Click the .exe file to install the extension. Note: See the Avid MediaCentral Platform Services v2.3 ReadMe for additional information regarding support of Active-X plugins in Chrome. Enabling MOS To use the plug-ins for a user you need to enable MOS in MediaCentral. Select Home > User Settings > MOS and then select “MOS enabled.” 210 MCS 2.3 Installation and Configuration Guide Installing Plug-Ins For procedures on how to install plug-ins, see the documentation for the plug-in. After installation and configuration, plug-ins are listed at the bottom of the Panes menu. If you do not see the plugin, review the following information on the Avid Knowledge Base: http://avid.force.com/pkb/articles/en_US/troubleshooting/Avid-Interplay-Central-Avid-MOSPlugin-is-disabled-by-Chrome Uninstalling the Chrome Extension If you need to uninstall the Chrome Extension, use the Windows Control Panel. Do not use the Chrome Extensions page. 1. Click Start and select Control Panel. 2. Click Programs and Features. 3. Right-click Avid MediaCentral MOS plugin and select Uninstall. Click Yes and follow the prompts. For more information about MOS plug-ins, see the Avid MediaCentral User’s Guide or the Avid MediaCentral Help. Enabling MediaCentral MOS Plug-Ins in Internet Explorer The instructions in this appendix were produced for Internet Explorer 9.0.8112.16421 using Google Chrome Frame 65.169.107 on Windows 7 x86_64 SP1. Updates to any of these applications may change the steps below, including the order in which you perform them. Once you complete the procedure, the Avid ActiveX container is available in IE9. When a MOSenabled user logs in, a list of their installed ActiveX plug-ins appears at the bottom of the Panes menu. Opening a plug-in will create a new tab. (Press F5 if the tab is empty when loaded.) The tab can be dragged out of Internet Explorer, permitting drag and drop into the IPC page. To enable MediaCentral MOS plug-ins in IE: 1. Launch Internet Explorer and enter the URL of the MCS server (or cluster) in the address bar (e.g. https:// ). Bypass the certificate warning, if one is present. The MediaCentral sign-in page informs you that the Google Chrome Frame is required. 211 MCS 2.3 Installation and Configuration Guide 2. Install Google Chrome Frame using the link on the sign in page. Note: Google Chrome Frame must be installed as user with Administrator rights. The Avid ActiveX container also requires administrator elevation. 3. A dialog should appear indicating the ChromeFrame BHO add-on from Google Inc is ready for use. Select Enable in that dialog. 4. Navigate once again to MCS server or cluster (e.g. https:// ) and log in as a user for whom MOS plug-ins are enabled. Note: To enable MOS for the logged in user, in MediaCentral, select Home -> User Settings -> MOS and then select “MOS enabled” 5. Download and run setup.exe as prompted. If your receive a "This webpage is not available" message, refresh with F5, and then say Yes to proceed. Follow the instructions appearing in the Avid MediaCentral MOS plugin installation wizard, and accept the defaults to install the extension. 6. Close and re-open Internet Explorer. Navigate to MediaCentral and log in as the same user. Do not download setup.exe again. Sign out of MediaCentral and close IE. This step forces Chrome Frame to register the Avid extension. 7. In Windows Explorer, navigate to the following directory: C:\Users\ \AppData\Local\Google\Chrome Frame\User Data\iexplorer\Default 8. Open the “Preferences” file in Notepad. 9. Locate the “known_disabled” key and delete the line. "known_disabled": [ "lmcebpepkojaapaoliodbjagahkpedph" ], 10. Search for the term "ActiveX" to find the "Avid MOS ActiveX Chrome Extension" object, and modify the “state” value from 0 to 1. "state": 1, 11. Save and close the Preferences file. 12. Once again, Launch IE, navigate to the MCS server or cluster (e.g. https:// ), and log in as the user for whom MOS plug-ins are enabled. Installed ActiveX plug-ins are now visible in MediaCentral, on the Panes menu. 212 MCS 2.3 Installation and Configuration Guide Sample ActiveX Object in the Preferences File For reference, the full ActiveX object after completion of the procedure is included below.

The files to edit are: • SYSTEM.CLIENT.VERSIONS • SYSTEM.CLIENT.WINDOWS Note: Additional files must be edited to ensure proper licensing for iNEWS integration with the MediaCentral mobile application. For more information, see Appendix E: The Avid MediaCentral UX Mobile Application on page 218. Verifying MediaCentral Licenses on iNEWS Before MediaCentral connects to iNEWS, verify that iNEWS is configured with the proper number of MediaCentral devices authorized to connect to the system based on the purchased licenses. iNEWS licensing limits can be identified from the iNEWS console using the following command: t NRCS-A$ status license A message similar to the following will appear on your screen: A is ONLINE and has been CONFIGURED. ID is INWS. System is AB. Master is A. Disk status is OK. The database is OPEN. Site Key............. : 009999 CPUs................. : 3 Workstation addresses : 3000 Workstation resources : 1000 COM resources........ : 5 Web Access resources. : 2 Web Client resources. : 10 Web API resources.... : 5 Wire Server resources : 8 Instinct resources... : 10 Mobile devices allowed: 2000 Community Sessions... : allowed. 214 MCS 2.3 Installation and Configuration Guide The three lines to pay attention to are: • Workstation addresses—indicates how many IP and/or MAC addresses can be specified in the SYSTEM.CLIENT.WINDOWS story. This story may be deleted from the iNEWS database if Workstation addresses shows a “site” license and IP-specific restriction is not wanted. • Workstation resources—the number of clients that can simultaneously connect to iNEWS, including iNEWS workstations, MediaCentral workstations, Apple iPad tablets, and Apple iPhone devices. • Mobile devices allowed—the number of mobile devices that can simultaneously connect to iNEWS. Note: Any time the iNEWS newsroom computer system is configured, your licensing information is checked. An error message appears in iNEWS if the configuration file defines more devices than are licensed. Editing SYSTEM.CLIENT.VERSIONS Some steps in the following procedure are conducted at the iNEWS console in superuser mode. For more information, see “The iNEWS Console” chapter in the “iNEWS Setup and Configuration Guide”. Note: For the correct iNEWS client version, see the Avid MediaCentral Platform Services ReadMe. To edit the SYSTEM.CLIENT.VERSIONS story in iNEWS: 1. Sign in to an iNEWS workstation as a system administrator, or any user account with write access to the System directory. 2. Navigate to SYSTEM.CLIENT.VERSIONS and open the first story in that queue. 3. On a new line, add the version of the iNEWS Client module that will run on the MediaCentral server. Note: To obtain the correct version of the iNEWS Client module, see the Avid MediaCentral Platform Services ReadMe. 4. Save the story. 5. Reconfigure the system. From the iNEWS console: a. Select the master computer, which is typically server A. b. Enter superuser mode, using the correct password. The dollar sign ($) at the end of the console’s server prompt will change to a pound sign (#). c. Take the system offline by typing: NRCS-A# offline 215 MCS 2.3 Installation and Configuration Guide d. Reconfigure the system by typing: NRCS-A# configure -n The above command must be run on the master computer. e. When the prompt reappears, bring the system back online by typing: NRCS-A# online f. Press Ctrl+D to leave superuser mode. The pound sign (#) at the end of the console’s server prompt will change back to a dollar sign ($). Editing SYSTEM.CLIENT.WINDOWS The following procedure only applies to sites that are not using a “site” license as Workstation addresses in iNEWS. You can review your site license information from the iNEWS console. For more information, see Verifying MediaCentral Licenses on iNEWS above. Some steps in the following procedure are conducted at the iNEWS console in superuser mode. For more information, see “The iNEWS Console” chapter in the “iNEWS Setup and Configuration Guide”. To edit the SYSTEM.CLIENT.WINDOWS story in iNEWS: 1. Sign in to an iNEWS workstation as a system administrator, or any user account with write access to the System directory. 2. Navigate to SYSTEM.CLIENT.WINDOWS and open the first story in that queue. 3. Add the IP address of the MediaCentral middleware server to a new line. Use a semicolon to add helpful commentary for future reference to the end of the line. For instance, type: 125.1.100.5 ;MediaCentral middleware server If there are multiple middleware (Web application) servers, you will need to add the IP address for each one on individual lines in the story. Note: You do not need to add to SYSTEM.CLIENT.WINDOWS the IP addresses of any MediaCentral client computers or devices. 4. Save the story. 5. Reconfigure the system. From the iNEWS console: a. Select the master computer, which is typically server A. 216 MCS 2.3 Installation and Configuration Guide b. Enter superuser mode, using the correct password. The dollar sign ($) at the end of the console’s server prompt will change to a pound sign (#). c. Take the system offline by typing: NRCS-A# offline d. Reconfigure the system by typing: NRCS-A# configure -n The above command must be run on the master computer. e. When the prompt reappears, bring the system back online by typing: NRCS-A# online f. Press Ctrl+D to leave superuser mode. The pound sign (#) at the end of the console’s server prompt will change back to a dollar sign ($). 217 MCS 2.3 Installation and Configuration Guide Appendix E: The Avid MediaCentral UX Mobile Application The Avid MediaCentral UX mobile application is a native user interface designed to run on the Apple iPad, iPhone and various Android-based devices. It enables direct, secure access to your station’s iNEWS newsroom computer system. You can use the Avid Central mobile application to view and approve news stories, navigate the news directory, play video sequences associated with stories and view a show’s scripts in presenter mode (iPad only) while signed in to your station’s iNEWS newsroom computer system. The MediaCentral mobile application can connect to your environment in one of two ways: • Wi-Fi • Carrier-specific cellular service— for example, 3G or 4G Note: The application automatically selects the first available connection from the list of options according to the priority shown in the list. Before You Begin Before connecting the MediaCentral mobile application to an iNEWS newsroom computer system, verify the following tasks have been completed: If you have a cluster configuration and intend to playback media on the mobile device, ensure that Gluster has been installed. This is a requirement for streaming to mobile devices. See: Replicating the File Caches using GlusterFS on page 121. Verify that the Hostname in the MediaCentral “ICPS> Player” System Settings has been configured with the system’s Fully Qualified Domain Name (FQDN). See Player Settings on page 99. Confirm that the mobile device can access MediaCentral via its Fully Qualified Domain Name (FQDN). See: Validating the FQDN for External Access on page 139. If this process does not return expected results, contact your local IT team to assist. Confirm that iNEWS is properly configured for licensed integration with the Avid Central mobile application. See: Appendix D: Configuring iNEWS for Integration with MediaCentral on page 214. Verify that Wi-Fi and/or or 3G/4G streams have been enabled on your MCS system. See: Enable / Disable 3G and Edge Streams on page 84. 218 MCS 2.3 Installation and Configuration Guide iNEWS Configuration for Mobile Integration Before connecting to an iNEWS system from a device running the Avid Central mobile application, some iNEWS system files might require adjustment. Editing the files enables the iNEWS servers to recognize the Avid Central mobile application as a licensed device. Complete the following two procedures to verify iNEWS configuration: • Editing SYSTEM.CLIENT.VERSIONS • Editing the iNEWS Configuration File Editing SYSTEM.CLIENT.VERSIONS You use the iNEWS console in superuser mode, for some steps in the following procedure. For more information, see the “iNEWS Setup and Configuration Guide”. 1. Sign in to an iNEWS workstation as a system administrator, or any user account with write access to the System directory. 2. Navigate to SYSTEM.CLIENT.VERSIONS and open the first story in that queue. 3. Confirm that the iNEWS Client module version appears as a line in the story. Note: To obtain the correct version of the iNEWS Client module, see the Avid MediaCentral Platform Services ReadMe. 4. If the version is correct, then close the story. You do not need to complete the rest of the steps in this procedure. 5. If the version is not correct or does not appear, on a new line, add the version of the iNEWS client module that will run on the MediaCentral server. 6. Save the story. 7. Reconfigure the system. From the iNEWS console: a. Select the master computer, which is typically server “A”. b. Enter superuser mode, using the correct password. The dollar sign ($) at the end of the console’s server prompt will change to a pound sign (#). c. Take the system offline by typing: NRCS-A# offline d. Reconfigure the system by typing: NRCS-A# configure e. When the prompt reappears, bring the system back online by typing: NRCS-A# online f. Press Ctrl+D to leave superuser mode. The pound sign (#) at the end of the console’s server prompt will change back to a dollar sign ($). 219 MCS 2.3 Installation and Configuration Guide Editing the iNEWS Configuration File The configuration file (/site/config) lists all devices, servers, and resources configured to run on your iNEWS newsroom computer system and how they are connected. If a mobile device does not appear in the configuration file, you cannot use it with the iNEWS newsroom computer system. The Avid Central mobile application uses the same G (inws) sessions in the configuration file as other MediaCentral Web clients or as iNEWS workstations. You need to confirm that there are enough sessions configured to handle simultaneous connections from these types of devices available to users at your site. Note: You need to edit the configuration file only if there are not enough sessions. If you need to edit the configuration file, see “The iNEWS Console” and “System Configuration” chapters in the “iNEWS Setup and Configuration Guide”. Also, some steps require use of ed, the line editor. If you do not know how to use the line editor to modify lines in the file, see “The Line Editor, ed” in the “iNEWS Setup and Configuration Guide”. To edit /site/config for the Avid Central mobile application: 1. Select all servers. Caution: Whenever you make changes to any iNEWS site file, such as the configuration file, you must select all servers in your system at the console. Unlike database stories, site files are not automatically mirrored from one computer’s disk to another. 2. Type the following and press Enter: ed /site/config The editor displays a numerical value indicating the file size expressed as the number of characters, including spaces and returns. The configuration file has two major sections: the host section and the device section. For the Avid Central mobile integration, both must be edited. 3. In the host section, add a resource list entry, using the following format. reslist ; For example: reslist 2001:2005 ;iNEWS and IPC sessions Note: For dual or triple server systems, the configuration file has multiple host sections to define which server handles which devices under various circumstances. You should add resource list entries to each host section. 220 MCS 2.3 Installation and Configuration Guide 4. In the INWS sessions section, add a resource line for the devices, using the following format: inws - gnews ; For example: inws 2001:2005 - gnews – 5. Type w to write (save) your changes to disk. Caution: Do not use an uppercase W in this step. Uppercase W appends the file you edit to the existing file. The resulting file might be unreadable and lead to problems with running your iNEWS system. 6. Type q to quit the line editor. 7. (Optional) Use the configure command to test your configuration changes, using the following syntax: configure /site/config For example: configure /site/config ab a When the prompt reappears, the configuration file has been checked. If the system detects any errors, it displays appropriate “bad configuration” messages. 8. Reconfigure the system. From the iNEWS console: a. Select the master computer, which is typically server A. b. Enter superuser mode, using the correct password. The dollar sign ($) at the end of the console’s server prompt changes to a pound sign (#). c. Take the system offline by typing: NRCS-A# offline d. Reconfigure the system by typing: NRCS-A# configure e. When the prompt reappears, bring the system back online by typing: NRCS-A# online f. Press Ctrl+D to leave superuser mode. The pound sign (#) at the end of the console’s server prompt changes back to a dollar sign ($). 221 MCS 2.3 Installation and Configuration Guide Installing Avid Central on an iOS Device The following procedure assumes licensing, setup, and configuration of the MediaCentral and iNEWS servers have already been completed.
