This guide is primarily geared toward commercial type NonStop NS-series servers (see Differences Between Integrity NonStop NS-Series Systems on page 2-2 for highlevel architectural and hardware differences between the various commercial models). While basic monitoring principles, such as Using OSM to Monitor the System on page 3-7, apply to Telco as well as commercial systems, refer to the NonStop NS-Series Carrier Grade Server Manual for hardware details and service procedures specific to Telco systems. Note. NS-series refers to the hardware that makes up the server. H-series refers to the software that runs on the server. The term, NonStop server, refers to both NonStop S-series servers and Integrity NonStop NS-series servers. Use this guide along with the Guardian User’s Guide and the written policies and procedures of your company regarding: • • • • General operations Security System backups Starting and stopping applications Who Should Use This Guide This guide is written for operators who perform system hardware operations.

For manuals not available in the H-series collection, please refer to the G-series collection on NTL. For comprehensive information about performing operations tasks for an Integrity NonStop NS-series server, you need both this guide and the Guardian User’s Guide. The Guardian User’s Guide describes some tasks not covered in this guide, such as supporting users of the system. The Guardian User’s Guide describes routine tasks common to system operations on all NonStop servers. Instructions and examples show how to support users of the system, how to monitor operator messages, how to control the spooler, and how to manage disks and tapes. Numerous tools that support these functions are also documented. Some monitoring procedures in the Guardian User’s Guide have information about using only the Subsystem Control Facility (SCF). That guide does not generally describe any monitoring procedures using the OSM packages. Information about the use of OSM, such as how to migrate from TSM to OSM, how to install and configure OSM server and client components, and how to use the OSM Service Connection, appear in these manuals: • • • OSM Migration and Configuration Guide NonStop System Console Installer Guide OSM Service Connection User’s Guide (available in NTL and as online help within the OSM Service Connection) Servers that are connected in ServerNet clusters require special installation and operating procedures that are not documented in this manual. Such information is instead provided with the appropriate cluster documentation and the ServerNet Cluster Supplement for Integrity NonStop NS-Series Servers. In the 6780 ServerNet cluster environment, installation and operating procedures are documented in these manuals: • ServerNet Cluster 6780 Planning and Installation Guide • ServerNet Cluster 6780 Operations Guide Installation and operating procedures for earlier server clusters (those using 6770 switches) are documented in: • ServerNet Cluster Manual HP Integrity NonStop NS-Series Operations Guide —529869-005 xvii Support and Service Library About This Guide OSM is the required system management tool for servers that use 6780 switches in ServerNet clusters, but OSM also provides system management for earlier versions of ServerNet clusters. For other documentation related to operations tasks, refer to Appendix C, Related Reading.

General Syntax Notation The following list summarizes the notation conventions for syntax presentation in this manual. HP Integrity NonStop NS-Series Operations Guide —529869-005 xviii General Syntax Notation About This Guide UPPERCASE LETTERS. Uppercase letters indicate keywords and reserved words; enter these items exactly as shown. Items not enclosed in brackets are required. For example: MAXATTACH lowercase italic letters. Lowercase italic letters indicate variable items that you supply. Items not enclosed in brackets are required. For example: file-name computer type. Computer type letters within text indicate C and Open System Services (OSS) keywords and reserved words; enter these items exactly as shown. Items not enclosed in brackets are required. For example: myfile.c italic computer type. Italic computer type letters within text indicate C and Open System Services (OSS) variable items that you supply. Items not enclosed in brackets are required. For example: pathname [ ] Brackets. Brackets enclose optional syntax items. For example: TERM [\system-name.]$terminal-name INT[ERRUPTS] A group of items enclosed in brackets is a list from which you can choose one item or none. The items in the list may be arranged either vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of brackets and separated by vertical lines. For example: FC [ num ] [ -num ] [ text ] K [ X | D ] address { } Braces. A group of items enclosed in braces is a list from which you are required to choose one item. The items in the list may be arranged either vertically, with aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example: LISTOPENS PROCESS { $appl-mgr-name } { $process-name } ALLOWSU { ON | OFF } | Vertical Line. A vertical line separates alternatives in a horizontal list that is enclosed in brackets or braces. For example: INSPECT { OFF | ON | SAVEABEND } HP Integrity NonStop NS-Series Operations Guide —529869-005 xix Notation for Messages About This Guide … Ellipsis. An ellipsis immediately following a pair of brackets or braces indicates that you can repeat the enclosed sequence of syntax items any number of times. For example: M address [ , new-value ]… [ - ] {0|1|2|3|4|5|6|7|8|9}… An ellipsis immediately following a single syntax item indicates that you can repeat that syntax item any number of times. For example: "s-char…" Punctuation. Parentheses, commas, semicolons, and other symbols not previously described must be entered as shown. For example: error := NEXTFILENAME ( file-name ) ; LISTOPENS SU $process-name.#su-name Quotation marks around a symbol such as a bracket or brace indicate the symbol is a required character that you must enter as shown. For example: "[" repetition-constant-list "]" Item Spacing. Spaces shown between items are required unless one of the items is a punctuation symbol such as a parenthesis or a comma. For example: CALL STEPMOM ( process-id ) ; If there is no space between two items, spaces are not permitted. In the following example, there are no spaces permitted between the period and any other items: $process-name.#su-name Line Spacing. If the syntax of a command is too long to fit on a single line, each continuation line is indented three spaces and is separated from the preceding line by a blank line. This spacing distinguishes items in a continuation line from items in a vertical list of selections. For example: ALTER [ / OUT file-spec / ] LINE [ , attribute-spec ]… Notation for Messages The following list summarizes the notation conventions for the presentation of displayed messages in this manual. Bold Text. Bold text in an example indicates user input entered at the terminal. For example: ENTER RUN CODE ?123 CODE RECEIVED: 123.00 HP Integrity NonStop NS-Series Operations Guide —529869-005 xx Notation for Messages About This Guide The user must press the Return key after typing the input. Nonitalic text. Nonitalic letters, numbers, and punctuation indicate text that is displayed or returned exactly as shown. For example: Backup Up. lowercase italic letters. Lowercase italic letters indicate variable items whose values are displayed or returned. For example: p-register process-name [ ] Brackets. Brackets enclose items that are sometimes, but not always, displayed. For example: Event number = number [ Subject = first-subject-value ] A group of items enclosed in brackets is a list of all possible items that can be displayed, of which one or none might actually be displayed. The items in the list might be arranged either vertically, with aligned brackets on each side of the list, or horizontally, enclosed in a pair of brackets and separated by vertical lines. For example: proc-name trapped [ in SQL | in SQL file system ] { } Braces. A group of items enclosed in braces is a list of all possible items that can be displayed, of which one is actually displayed. The items in the list might be arranged either vertically, with aligned braces on each side of the list, or horizontally, enclosed in a pair of braces and separated by vertical lines. For example: obj-type obj-name state changed to state, caused by { Object | Operator | Service } process-name State changed from old-objstate to objstate { Operator Request. } { Unknown. } | Vertical Line.

It provides an introduction to the other sections in this guide. Understanding the Operational Environment To understand the operational environment: • • • If you are already familiar with other NonStop systems, see Appendix A, Operational Differences Between Systems Running G-Series and H-Series RVUs. For a brief introduction to the system organization and the location of system components in an Integrity NonStop server, see Section 2, Determining Your System Configuration. For information about various software tools and utilities you can use to perform system operations on an Integrity NonStop server, see Appendix B, Tools and Utilities for Operations. What Are the Operator Tasks? The system operations described in this guide include: • • • • • • • Monitoring the system and performing recovery operations Preparing for and recovering from power failures Stopping and powering off the system Powering on and starting the system Performing preventive maintenance Operating disk drives and tape drives Responding to spooler problems Monitoring the System and Performing Recovery Operations Checking for indications of potential system problems by monitoring the system is part of the normal system operations routine. You perform recovery operations to restore a malfunctioning system component to normal use. Most recovery procedures for Integrity NonStop servers can be performed online. Monitoring the status of all system components and performing recovery operations are described in: • • • • • • • Section 3, Overview of Monitoring and Recovery Section 4, Monitoring EMS Event Messages Section 5, Processes: Monitoring and Recovery Section 6, Communications Subsystems: Monitoring and Recovery Section 7, ServerNet Resources: Monitoring and Recovery Section 8, I/O Adapters and Modules: Monitoring and Recovery Section 9, Processors and Components: Monitoring and Recovery HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -2 Introduction to Integrity NonStop NS-Series Operations • • • • Preparing for and Recovering from Power Failures Section 10, Disk Drives: Monitoring and Recovery Section 11, Tape Drives: Monitoring and Recovery Section 12, Printers and Terminals: Monitoring and Recovery Section 13, Applications: Monitoring and Recovery Recovery operations for a system console are not discussed in this guide. For recovery procedures for a system console and the applications installed on the system console, see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server. Preparing for and Recovering from Power Failures You can minimize unplanned outage time by having procedures to prepare and recover quickly from power failures, as described in Section 14, Power Failures: Preparation and Recovery. Stopping and Powering Off the System HP recommends a specific set of procedures for stopping and powering off an Integrity NonStop server or its components, as described in Section 15, Starting and Stopping the System. Powering On and Starting the System HP recommends a specific set of procedures for powering on and starting an Integrity NonStop server or its components, as described in Section 15, Starting and Stopping the System. Creating Startup and Shutdown Files HP recommends a specific set of procedures for creating startup and shutdown files on an Integrity NonStop server or its components, as described in Section 16, Creating Startup and Shutdown Files. Performing Preventive Maintenance Routine preventive maintenance consists of: • • • • Dusting or cleaning enclosures as needed Cleaning tape drives regularly Evaluating tape condition regularly Cleaning and reverifying tapes as needed Routine hardware maintenance procedures are described in Section 17, Preventive Maintenance. Operating Disk Drives and Tape Drives Refer to the documentation shipped with the drive. HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -3 Introduction to Integrity NonStop NS-Series Operations Responding to Spooler Problems Responding to Spooler Problems Refer to the Spooler Utilities Reference Manual. Updating Firmware Refer to the H06.xx Software Installation and Upgrade Guide Determining the Cause of a Problem: A Systematic Approach Continuous availability of your NonStop system is important to system users, and your problem-solving processes can help make such availability a reality. To determine the cause of a problem on your system, start by trying the easiest, least expensive possibilities. Move to more complex, expensive possibilities only if the easier solutions fail. This subsection presents an approach you can use in your operations environment to: • • • Determine the possible causes of problems Systematically fix or escalate such problems Develop ways of preventing the same problems from recurring The four basic steps in systematic problem solving are: Task Page Task 1: Get the Facts 1-6 Task 2: Find and Eliminate the Cause of the Problem 1-7 Task 3: Escalate the Problem If Necessary 1-8 Task 4: Prevent Future Problems 1-9 A Problem-Solving Worksheet Table 1-1 is a worksheet that you can use to help you through the problem-solving process. Use this worksheet to: • • • • Get the facts about a problem Find and eliminate the cause of the problem Make any appropriate escalation decisions Prevent future problems Make copies of this worksheet and use it to collect and analyze facts regarding a problem you are experiencing. The results might not tell you exactly what is occurring, but they will narrow down the number of possible causes. You are authorized by HP to reproduce this worksheet only for the purpose of operating your system. HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -4 Introduction to Integrity NonStop NS-Series Operations A Problem-Solving Worksheet Table 1-1. Problem-Solving Worksheet Problem Facts Possible Causes What? Where? When? Magnitude? Situation Facts Escalation Decision Plan to Verify/Fix Plan to Prevent and Control Damage HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -5 Introduction to Integrity NonStop NS-Series Operations Task 1: Get the Facts Task 1: Get the Facts The first step in solving any problem is to get the facts. Although it is tempting to speculate about causes, your time is better spent in first understanding the symptoms of the problem. Task 1a: Determine the Facts About the Problem To get a clear, complete description of problem symptoms, ask questions to determine the facts about the problem. For example: Category Questions to Ask What? What are you having trouble with? What specifically is wrong? Where? Where did you first notice the problem? Where has it occurred since you first noticed it? Which applications, components, devices, and people are affected? When? When did the problem occur? What is the frequency of the problem? Has this problem occurred before this time? Magnitude? Is the problem quantifiable in any way? (That is, can it be measured?) For example, how many people are affected? Is this problem getting worse? Task 1b: Determine the Facts About the Situation Collect facts about the situation in which the problem arose. A clear description of the situation that led to the problem could indicate a simple solution. Examples of questions to ask are: • • • • • • Who reported the problem and how can this person be contacted? How critical is the situation? What events led to the problem? Has anything changed recently that might have caused the problem? What event messages have you received? What is the current configuration of the hardware and software products affected? An example of information you might obtain from asking questions: Question Answer What is happening that indicates a problem? A terminal is hung. Where is this problem occurring? In the office of USER.BONNIE. The affected terminal is named $JT1.#C02. When is this problem occurring? At 8:30 this morning and also at the same time two days ago. Both times, this problem occurred after three unsuccessful attempts to log on. What is the magnitude of this problem? Intermittent; the problem seemed to disappear on its own when it first occurred two days ago. HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -6 Introduction to Integrity NonStop NS-Series Operations Task 2: Find and Eliminate the Cause of the Problem Task 2: Find and Eliminate the Cause of the Problem After you collect the facts, you are ready to begin considering the possible causes of a problem. Using these facts and relying on your knowledge and experience, begin to list possible causes of the problem. Task 2a: Identify the Most Likely Cause To evaluate the possible causes of any problem, you must compare each cause with the problem symptoms. The problem-solving worksheet gives you a guide for accomplishing this task. In the following example: • • Possible causes become column headings Entries made in the worksheet’s rows indicate whether the cause in that column could have produced the problem symptoms you listed in that row. ° ° Write yes in the appropriate box if that cause could explain that symptom. Write no in the appropriate box if a possible cause does not explain a fact. The most likely cause is the one that best explains all the facts; that is, the cause that contains the most yes answers. For example, possible causes of a hung terminal problem could be: • • • A terminal hardware problem A stopped or suspended TACL process System security, which locks a user out after three unsuccessful logon attempts This worksheet lists some possible causes of a hung terminal and illustrates further how to evaluate the possible causes: Problem Facts Possible Causes Terminal hardware TACL process Security What? Terminal $JT1.#C02 is hung Yes Yes Yes Where? Office of USER.BONNIE Yes Yes Yes When? 8:30 a.m. today Two days ago at 8:30 a.m. After 3 failed logon attempts Yes Yes No Yes Yes No Yes Yes Yes Magnitude? Intermittent Goes away on its own ? ? Yes Yes Yes Yes HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -7 Introduction to Integrity NonStop NS-Series Operations Task 3: Escalate the Problem If Necessary Task 2b: Fix the Most Probable Cause of the Problem For the example in the worksheet, the most likely cause of the hung terminal is a security problem. Ask yourself what would be the fastest, least expensive, safest, and surest way of verifying that this is the most probable cause of the problem. Once you have determined the most likely cause, try to fix it. Follow through and implement the appropriate solution. If this solution does not fix the problem, continue trying other possible solutions that are reasonable considering time, expense, and safety. Task 3: Escalate the Problem If Necessary If the solutions you tried in the previous tasks do not solve the problem, you might consider escalating the problem to get additional help. Task 3a: Determine Whether You Need to Escalate the Problem After you complete each task in the problem-solving process, you must decide whether you can continue by yourself or if you must ask for help. Ask yourself these questions: • • • • • • Do I have the authority to resolve this problem? Do I have the necessary knowledge? Do I have the skill? Do I have the time? What other people need to become involved, if any? Who needs to be informed about the problem’s status? Task 3b: Provide Documentation If you decide to escalate the problem, you might be required to document the problem by providing: • • • • A problem identification number A problem classification A complete description and history of the problem Diagnostic information such as copies of the event log, results of memory dumps, and so on You might also have procedures at your site for logging problems. If you have a shift log or problem log, make timely entries in the log. HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -8 Introduction to Integrity NonStop NS-Series Operations Task 4: Prevent Future Problems Task 4: Prevent Future Problems Solving problems that occur with your system can be exciting because it is active and stimulating. Preventing problems is often less dramatic. But in the end, prevention is more productive than solving problems. The more work you do to prevent problems before they arise, the fewer problems that will arise at potentially critical times. These questions provide a framework for your problem-prevention efforts: • • • • • • • • Why did this problem occur? What was the root cause? Were there any contributing causes? How serious was the problem? What is the likelihood that it will occur again? Is it possible to eliminate the causes of this problem? Is it possible to reduce the likelihood that this problem will occur in the future? Can automation tools be used to detect and respond to preliminary symptoms of this problem? Can anything be done now to minimize the damage that would result from a reoccurrence of this problem? Can the problem resolution process be improved in any way? Logging On to an Integrity NonStop Server Many operations and troubleshooting tasks are performed by logging on to your Integrity NonStop server from a system console and using the TACL command interpreter or one of the OSM applications. For example, the TACL command interpreter allows you to access SCF, which you use to configure, control, and collect information about objects within subsystems. For examples of OSM tasks and functions, see Overview of OSM Applications on page 1-11. System Consoles A system console is a personal computer approved by HP to run maintenance and diagnostic software for Integrity NonStop servers. New system consoles are preconfigured with the required HP and third-party software. When upgrading to the latest RVU, software upgrades can be installed from the HP NonStop System Console Installer CD. System consoles communicate with Integrity NonStop servers over a dedicated service LAN (local area network). System consoles configured as the primary and backup dialout points are referred to as the primary and backup system consoles, respectively. The OSM Low-Level Link and OSM Notification Director applications reside on the system console, along with other required HP and third-party software. OSM Service Connection and OSM Event Viewer software resides on your server, and connectivity HP Integrity NonStop NS-Series Operations Guide —529869-005 1 -9 Introduction to Integrity NonStop NS-Series Operations Opening a TACL Window is established from the console through Internet Explorer browser sessions. For more information, see Launching OSM Applications on page 1-11. Opening a TACL Window On a system console, you must open a TACL window before you can log on to the TACL command interpreter. For information about logging on to a TACL command interpreter, see the Guardian User’s Guide. You can use any of the following methods to open a TACL window. Opening a TACL Window Directly From OutsideView If you know the IP address of the NonStop server (not that of OSM), use this method: 1. Select Start>Programs>OutsideView32 7.1. 2. From the Session menu, select New. The New Session Properties dialog box appears. 3. From the New Session Properties dialog box, Session tab, click IO Properties. The TCP/IP Properties dialog box appears. 4. In the TCP/IP Properties dialog box: a. In the Host name or IP address and port box, type the IP address, followed by a space and the port number. For example: 172.17.22.187 23 The port number is 23 for a TACL prompt and 301 for a Startup TACL prompt. In general, you should use port number 23 to perform operations tasks. b. Click OK. 5. From the New Session Properties dialog box, click OK. A TACL window appears. 6. Log on to the TACL prompt. Opening a TACL Window From the Low-Level Link You can also open a TACL window from the OSM Low-Level Link application as described in the Troubleshooting section in Opening Startup Event Stream and Startup TACL Windows on page 15-22. For more details on the functions of the TACL command interpreter, see Appendix B, Tools and Utilities for Operations. HP Integrity NonStop NS-Series Operations Guide —529869-005 1-10 Introduction to Integrity NonStop NS-Series Operations Overview of OSM Applications Overview of OSM Applications HP NonStop Open System Management (OSM) applications perform a variety of functions, such as: • • • • The OSM Low-Level Link Application is primarily used for down-system support, such as Two startup event stream windows and two startup TACL windows are automatically launched on the system console configured to receive them. on page 15-6, Recovery Operations for Processors on page 9-9, and configuring IOAM, VIO, and P-switch modules (see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server). The OSM Service Connection is used to monitor, inventory, and perform actions on system and ServerNet Cluster components. See Using OSM to Monitor the System on page 3-7 for an overview of how the OSM Service Connection is used to monitor your system components. The OSM Event Viewer is used for Section 4, Monitoring EMS Event Messages. The OSM Notification Director is used for Monitoring Problem Incident Reports on page 3-12 and dialing out information to your service provider. Launching OSM Applications Several operations tasks in this guide require you to log on to one of the OSM applications. Assuming that all OSM client components have been installed on the system console, launch the desired application as described below, then see the online help (or default home page, for the browser-based OSM applications) for log-on instructions. To launch OSM applications: Start>Programs>HP OSM. Then select the name of the application to launch: • • • • • OSM Service Connection OSM Low-Level Link Application OSM Notification Director>Start/Stop OSM Event Viewer OSM System Inventory Tool The OSM Service Connection and the OSM Event Viewer are browser-based applications. Assuming that the OSM Console Tools component has been installed on the system console, the Start menu shortcuts launch a default web page for these two applications. From that page, you can select the system of your choice from the list of bookmarks displayed in the left column of the page (available bookmarks include those that were user-created during previous sessions and those converted automatically from an existing OSM system list). If no bookmarks are available, the web page also contains instructions on how to access these applications by entering a system URL as an Internet Explorer address. The system console-based OSM Console Tools component is not required to use the OSM Service Connection and the OSM Event HP Integrity NonStop NS-Series Operations Guide —529869-005 1-11 Introduction to Integrity NonStop NS-Series Operations Service Procedures Viewer applications; it merely installs the Start menu shortcuts and default home pages to make accessing these applications easier. You can also simply open a new Internet Explorer browser window and enter the URL of the system you wish to access. For more information on configuring, accessing, or using OSM applications, see: • • • OSM Migration and Configuration Guide OSM Service Connection User’s Guide Online help within the OSM Service Connection, Low-Level Link, Notification Director, and Event Viewer applications Service Procedures OSM offers a variety of guided procedures, interactive actions, and documented service procedures to automate or assist with system serviceability. They are launched by actions within the OSM Service Connection, and include online help. For a list (and help files) for service procedures, both those incorporated into OSM and others that are not part of OSM, refer to the Support and Service Library. Support and Service Library These NTL Support and Service library categories provide procedures, part numbers, troubleshooting tips, and tools for servicing NonStop S-series and Integrity NonStop NS-series systems: • • • • • Hardware Service and Maintenance Publications Service Information Service Procedures Tools and Download Files Troubleshooting Tips Within these categories, where applicable, content might be further categorized according to server or enclosure type.

For detailed information on system hardware organization, refer to the NonStop NSxxxx Planning Guide for your Integrity NonStop NS16000, NS14000, or NS1000 server. HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -1 Determining Your System Configuration Modular Hardware Components Modular Hardware Components Hardware for Integrity NonStop systems is implemented in modules or enclosures that are installed in modular cabinets. The servers include these hardware components: • • • • • • • • • • • • • Modular Cabinet with Power Distribution Unit (PDU) NonStop Blade Complex NonStop Blade Element Logical Synchronization Unit (LSU) (in Integrity NonStop NS16000 and NS14000 systems only; Integrity NonStop NS1000 systems have no LSUs) Processor Switch, or p-switch (in Integrity NonStop NS16000 systems only; Integrity NonStop NS14000 and NS1000 systems have no processor switches) I/O Adapter Module (IOAM) Enclosure, including subcomponent I/O Adapters: • Fibre Channel ServerNet adapter (FCSA) • Gigabit Ethernet 4-port ServerNet adapter (G4SA) • 4-Port ServerNet Extenders (4PSEs) (Integrity NonStop NS14000 and NS1000 systems only) VIO Enclosure (displayed by OSM as a VIO Module object) — For more information, see Integrity NonStop NS14000 Systems, Integrity NonStop NS1000 Systems, or the Versatile I/O (VIO) Manual. Fibre Channel disk module (FCDM) Maintenance Switch (Ethernet) UPS and ERM NonStop System Console (to manage the system) Cable Management Devices Enterprise Storage System (ESS) Differences Between Integrity NonStop NS-Series Systems NonStop System Architectures Integrity NonStop NS-series systems offer of a variety of architecture and configuration options to suit different customer needs. Integrity NonStop NS16000 and Integrity NonStop NS14000 systems take advantage of NonStop advanced architecture (NSAA). For more information, see the NonStop NS16000 Planning Guide or NonStop NS14000 Planning Guide. Integrity NonStop NS1000 systems employ the NonStop value architecture (NSVA). For more information, see the NonStop NS1000 Planning Guide. Integrity NonStop NS16000 Systems In Integrity NonStop NS16000 systems, IOAM enclosures connect through ServerNet links to the processors via the processor switches. One IOAM enclosure provides ServerNet connectivity for up to 10 ServerNet I/O adapters on each of the two ServerNet fabrics. FCSAs and G4SAs can be installed in an IOAM enclosure for HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -2 Determining Your System Configuration Differences Between Integrity NonStop NS-Series Systems communications to storage devices and subsystems as well as to LANs. Additional IOAM enclosures can be added to increase connectivity and storage resources. Integrity NonStop NS16000 systems connect to NonStop S-series I/O enclosures by using fiber-optic ServerNet links to connect the p-switches of the Integrity NonStop system to IOMF2 CRUs in the I/O enclosures. Integrity NonStop NS14000 Systems In Integrity NonStop NS14000 systems, there are no p-switches. There are now two types of NS14000 systems: • • A NonStop NS14000 system consisting of a single IOAM enclosure, with an I/O adapter module on each ServerNet fabric — processor connections are made through ports on 4-Port ServerNet Extenders (4PSEs), located in slot one and optionally slot 2 of each I/O adapter module, to the processors via the LSUs. The IOAM enclosure provides ServerNet connectivity for up to 8 ServerNet I/O adapters on each of the two ServerNet fabrics (FCSAs and G4SAs can be installed in slots 2 through 5 of the two IOAMs in the IOAM enclosure for communications to storage devices and subsystems as well as to LANs). Integrity NonStop NS14000 systems do not support connections to additional IOAM enclosures or NonStop S-series I/O enclosures. A NonStop NS14000 system consisting of two VIO enclosures, one on each ServerNet fabric — processor connections for processors 0-3 are made through ports 1-4 of the VIO Logic Board in slot 14 of each VIO enclosure, via the LSUs. An optional Optical Extender PIC in slot 2 provides for additional processor connectivity (processors 4-7). VIO enclosures have embedded ports and allow for optional expansion ports to supply the equivalent functionality provided by FCSAs and G4SAs in NS14000 systems with IOAMs. Integrity NonStop NS14000 systems do not support connections to additional IOAM enclosures or NonStop S-series I/O enclosure For more information on Integrity NonStop NS14000 systems, see the Versatile I/O (VIO) Manual, the NonStop NS14000 Planning Guide, or the NonStop NS14000 Hardware Installation Manual. Integrity NonStop NS1000 Systems Integrity NonStop NS1000 systems have no processor switches or LSUs. Like Integrity NonStop NS14000 systems, there are now two types: those consisting of a single IOAM enclosure (two IOAMs) and those consisting of one VIO enclosure for each fabric. ServerNet connectivity for each type is accomplished as described for the Integrity NonStop NS14000 Systems, except for the absence of the LSUs. Integrity NonStop NS1000 systems do not support connections to NonStop S-series I/O enclosures. Besides the architectural differences, Integrity NonStop NS1000 systems also utilize different NonStop Blade Elements than Integrity NonStop NS16000 or NS14000 systems. For more information on Integrity NonStop NS1000 systems, refer to the NonStop NS1000 Planning Guide and the NonStop NS1000 Hardware Installation Manual. HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -3 Determining Your System Configuration Terms Used to Describe System Hardware Components Terms Used to Describe System Hardware Components The terms used to describe system hardware components vary. These terms include: • Device • System resource or object Device A device can be a physical device or a logical device. A physical device is a physical component of a computer system that is used to communicate with the outside world or to acquire or store data. A logical device is a process used to conduct input or output with a physical device. System Resource or Object The term “system resource” is used in OSM documentation to refer to server components that OSM software displays, monitors, and often controls. The term “object” is often used when referring to a specific resource, such as “the Disk object.” All system resources are displayed in hierarchical form in the tree pane of the OSM Service Connection; many are also displayed in Physical or Inventory views of the view pane. The effect of selecting an object in either pane is the same: for example, you can view attributes for the selected system resource in the Attributes tab, view alarms for that resource (if any exist) in the Alarms tab, or right-click on the resource object and select Actions, to display the Actions dialog box (from which you can select and perform actions on the selected system resource). Besides physical hardware components, such as IOAM enclosures, power supplies, ServerNet adapters, and disk and tape drives, system resources also include logical entities that OSM supports, such as logical processors, ServerNet fabrics, and LIFs (logical interfaces). Recording Your System Configuration As a system operator, you need to understand how your system is configured so you can confirm that the hardware and system software are operating normally. If problems do occur, knowing your configuration allows you to pinpoint problems more easily. If your system configuration is corrupted, documentation about your configuration is essential for recovery. You should be familiar with the system organization, system configuration, and naming conventions. Several methods are available for researching and recording your system configuration: • • • Maintaining records in hard-copy format Using the OSM Service Connection to inventory your system In the OSM Service Connection tree pane, select the System object. From the View pane drop-down menu, select Inventory to display a list of the system’s hardware resources. Click Save to save this list to a Microsoft Excel file. Using SCF to list objects and devices and to display subsystem configuration information HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -4 Determining Your System Configuration Using SCF to Determine Your System Configuration For information on forms available that can help you record your system configuration, refer to the NonStop NSxxxx Planning Guide for your Integrity NonStop NS16000, NS14000, or NS1000 server. Using SCF to Determine Your System Configuration SCF is one of the most important tools available to you as a system operator. SCF commands configure and control the objects (lines, controllers, processes, and so on) belonging to each subsystem running on the Integrity NonStop NS-series server. You also use SCF to display information about subsystems and their objects. SCF accepts commands from a workstation, a disk file, or an application process. It sends display output to a workstation, a file, a process, or a printer. Some SCF commands are available only to some subsystems. An overall SCF reference is the SCF Reference Manual for H-Series RVUs. Subsystem-specific information appears in a separate manual for each subsystem. For a partial list of these manuals, refer to Appendix C, Related Reading. More details about the functions of SCF appear in Subsystem Control Facility (SCF) on page B-4. SCF System Naming Conventions SCF object names usually follow a consistent set of naming conventions defined for each installation. HP preconfigures some of the naming conventions to create the logical device names for many SCF objects. System planning and configuration staff at your site likely will change or expand on the preconfigured file-naming conventions that HP provides, typically by establishing naming conventions for configuring such objects as storage devices, communication processes, and adapters. These conventions should simplify your monitoring tasks by making process or object functions intuitively obvious to someone looking at the object name. For example, in your environment, tape drives might be named $TAPEn, where n is a sequential number. The SCF Reference Manual for H-Series RVUs lists naming conventions for SCF objects, as well as HP reserved names that cannot be changed or used for other objects or processes in your environment. SCF Configuration Files Your system is delivered with a standard set of configuration files: • • The $SYSTEM.SYSnn.CONFBASE file contains the minimal configuration required to load the system. The $SYSTEM.ZSYSCONF.CONFIG file contains a standard system configuration created by HP. This basic configuration includes such objects as disk drives, tape HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -5 Determining Your System Configuration Using SCF to Display Subsystem Configuration Information drives, ServerNet adapters, the local area network (LAN) and wide area network (WAN) subsystem manager processes, the OSM server processes, and so on. You typically use this file to load the system. • The $SYSTEM.ZSYSCONF.CONFIG file is also saved on your system as the ZSYSCONF.CONF0000 file. All subsequent changes to the system configuration are made using SCF. The system saves configuration changes on an ongoing basis in the ZSYSCONF.CONFIG file. You have the option to save a stable copy of your configuration at any time in ZSYSCONF.CONFxxyy using the SCF SAVE command. For example: -> SAVE CONFIGURATION 01.02 You can save multiple system configurations by numbering them sequentially based on a meaningful convention that reflects, for example, different hardware configurations. Each time you load the system from CONFBASE or CONFxxyy, the system automatically saves in a file called ZSYSCONF.CONFSAVE a copy of the configuration file used for the system load. For guidelines on how to recover if your system configuration files are corrupted, refer to Troubleshooting and Recovery Operations on page 15-18. For certain SCF subsystems, configuration changes are persistent. The changes persist through processor and system loads unless you load the system with a different configuration file. Examples of these subsystems are the Kernel, ServerNet LAN Systems Access (SLSA), the storage subsystem, and WAN. For other SCF subsystems, the changes are not persistent. You must reimplement them after a system or processor load. Examples of these subsystems are General Device Support (GDS), Open System Services (OSS), and SQL communication subsystem (SCS). Using SCF to Display Subsystem Configuration Information SCF enables you to display, in varying levels of detail, the configuration of objects in each subsystem supported by SCF. For example, you can use the LISTDEV command to list all the devices on your system or to list the objects within a given subsystem. Then you can use the INFO command with a logical device name or device type to obtain information about a specific device or class of devices. Another useful command when displaying information is the ASSUME command. Use the ASSUME command to define a current default object and fully qualified object name. Then you can use INFO to display information just for that object. For example, if you type this command and then enter the INFO command without specifying an object, SCF displays only the information for the workstation called $Ll.#TERM1: > SCF ASSUME WS $L1.#TERM1 HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -6 Determining Your System Configuration Using SCF to Display Subsystem Configuration Information SCF LISTDEV: Listing the Devices on Your System To obtain listings for most devices and processes that have a device type known to SCF, at a TACL prompt type: > SCF LISTDEV In the example shown in Example 2-1, the SCF LISTDEV command lists all the physical and logical devices on the system.

HP Integrity NonStop NS-Series Operations Guide —529869-005 2 -8 Displaying SCF Configuration Information for Subsystems Determining Your System Configuration To display information about a particular device: > SCF LISTDEV TYPE n where n is a number for the device type. For example, if n is 3, the device type is disks. For the \MS9 system, entering LISTDEV TYPE 3 would display information for $DATA6, $DATA5, $DATA4, $DATA3, $DATA2, $DATA1, and $DATA. To display information for a given subsystem: > SCF LISTDEV subsysname where subsysname is the logical name of a subsystem; for example, $ZZKRN for the Kernel subsystem. Displaying SCF Configuration Information for Subsystems The following tables give some of the SCF commands that display configuration information for objects controlled by subsystems that are common to most Integrity NonStop NS-series systems. The examples use the SCF ASSUME command to make a given subsystem the current default object for gathering information. TCP/IP Subsystem These examples are based on a TCP/IP process named $ZTCO. Before using the commands listed in Table 2-2, type this command to make the TCP/IP subsystem the default object: > SCF ASSUME PROCESS $ZTCO Table 2-2.

It describes some common monitoring tasks. It also refers you to other sections or manuals for more information about monitoring specific system components, events, applications, or processes. HP Integrity NonStop NS-Series Operations Guide —529869-005 3 -1 Overview of Monitoring and Recovery Functions of Monitoring Functions of Monitoring You must monitor a system to ensure that it is operating properly and to recognize when corrective action is required. By monitoring a system, you can: • • • • • • • • Verify whether components are currently up or down Be quickly notified of error conditions, state changes, and threshold conditions that have been exceeded or are reaching their limits View a chronological list of events that can help with problem diagnosis and resolution Determine how much of a particular resource is being used; for example, processor capacity, disk or file space, or communications line bandwidth Find performance problems that can affect the users of the system Make better use of existing resources Ensure that products such as HP NonStop SQL/MP, HP NonStop SQL/MX, HP NonStop Transaction Management Facility (TMF), and Pathway are available Prevent many problems and outages from occurring Monitoring Tasks Regardless of the shift you work, certain areas of your hardware and software environment need to be checked on a regular basis. This subsection provides guidelines that will enable you to determine the general areas you should monitor. Working With a Daily Checklist A good method for ensuring that certain areas of your operations environment are monitored is to develop a checklist. Monitor these items on a system frequently. At least daily, monitor: • • • • • • • • OSM Service Connection GUI Event messages Alarms Problem incident reports The status of all system components The status of processes The status of all applications The performance of processors, disks, and communications lines (Monitoring performance is not discussed in this guide.) HP Integrity NonStop NS-Series Operations Guide —529869-005 3 -2 Overview of Monitoring and Recovery Tools for Checking the Status of System Hardware An example of a checklist you might use to standardize your routine daily monitoring tasks is: Task Operator’s name Date & time Notes and questions Check phone messages Check faxes Check e-mail Check shift log Check EMS event messages Check status of terminals Check comm. lines Check TMF status Check Pathway status Check disks Check tape drives Check processors Check printers Check spooler supervisor and collector processes Check ServerNet cluster status Tools for Checking the Status of System Hardware Several tools are available to check the status of system components in an Integrity NonStop NS-series server. The most frequently used tools are the OSM Service Connection and the Subsystem Control Facility (SCF). For information relating to system components in NonStop S-series servers, refer to the appropriate NonStop S-Series documentation. Table 3-1 lists the tools available to monitor system components.

In this way, you can develop a larger picture that encompasses the whole environment, including communications links and other objects and services that might be contributing to the problem or affected by it. To get comprehensive online descriptions of all the available SCF commands, use the SCF HELP command. The following subsections give instructions for using OSM and SCF to monitor and resolve problems. Using OSM to Monitor the System This section deals mostly with the OSM Service Connection, the primary OSM interface for system monitoring and serviceability. See Overview of OSM Applications on page 1-11 for examples of how the other OSM applications are used for monitoring-related functions. Using the OSM Service Connection The OSM Service Connection can be used in a variety of ways to monitor your system, including: • • • Use of colors and symbols to direct you to the source of any problems Attribute values for system resources, displayed in the Attributes tab and in many dialog boxes. Alarms, displayed in the Alarms tab and Alarm Summary dialog box. The following section presents one model for using the OSM Service Connection to monitor your system, along with a few other options. A Top-Down Approach The Management (or main) window of the OSM Service Connection uses a series of colors and symbols to notify you that problems exist within the system. You can tell at a high-level glance when problem conditions exist, then drill-down, or expand the tree pane to find the component reporting the problem. Figure 3-1 illustrates how both the the rectangular system icon (located at the top of the view pane) and the system object in the tree pane indicate problems within the system. The system icon, which is green when OSM is reporting no problems on the system, has turned yellow. The system icon in the tree pane is displaying a yellow arrow to indicate a problem within. HP Integrity NonStop NS-Series Operations Guide —529869-005 3 -7 Overview of Monitoring and Recovery Using the OSM Service Connection Figure 3-1. OSM Management: System Icons Indicate Problems Within VST310.vsd Note. In the OSM Service Connection Management window, the tree pane is located on the far left. In the lower right is the Overview pane. Located between them is the details pane, from which you can choose to view the Attributes or Alarms tab. Directly above the details pane is the view pane, from which you can choose a Physical or Inventory view of your system or ServerNet Cluster. The gray bar directly above the view pane is an OSM-specific toolbar (as opposed to the standard Internet Explorer menu bar at the top of the browser window). Expanding the system object in the tree pane, you can see a yellow arrow on the Group 110 object, indicating that the problem is located somewhere within that group. Expanding the tree pane further, as illustrated in Figure 3-2, yellow arrows on the IOAM Enclosure 110 and IOAM 110.3 objects reveal that the problem exists on a ServerNet adapter in slot 3 of that I/O module. The red bell-shaped icon by that resource object (in the tree pane) indicates that there is an alarm on the object. To obtain information about the alarm: 1. Click to select the object displaying the red triangular and bell-shaped symbols. 2. Select the Alarms tab from the details pane. HP Integrity NonStop NS-Series Operations Guide —529869-005 3 -8 Overview of Monitoring and Recovery Using the OSM Service Connection 3. Click to select the alarm, then right-click and select Details. Figure 3-2. Expanding the Tree Pane to Locate the Source of Problems VST311.vsd Check the Attributes tab (Figure 3-3) also, as a yellow or red triangular symbol indicates problem attribute values exist. In this case, the degraded Service State attribute was caused by an alarm. However, when a resource displays a yellow or red triangular object but no bell-shaped icon, it has no alarms but is reporting problem or degraded attribute values. HP Integrity NonStop NS-Series Operations Guide —529869-005 3 -9 Overview of Monitoring and Recovery Using the OSM Service Connection Figure 3-3. Attributes Tab VST312.vsd Using System Status Icons to Monitor Multiple Systems When you are monitoring multiple systems, you can create a System Status Icon for each system, allowing you to keep a high-level eye on each system while saving screen space. Figure 3-4 shows three separate System Status icons, each created by: 1. Establishing an OSM Service Connection session to the system. 2. From the Summary menu on the OSM toolbar, selecting System Status. You can then minimize, but not close, the OSM Service Connection Management window for each system. If the System Status icon for a system turns from green to yellow, as illustrated in Figure 3-4, open the Management window for that system and locate the problem as described in A Top-Down Approach on page 3-7. Figure 3-4. Using System Status Icons to Monitor Multiple Systems VST313.vsd HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 10 Overview of Monitoring and Recovery Using the OSM Service Connection Using Alarm and Problem Summaries Other options for monitoring your system with the OSM Service Connection include using the Alarm Summary (Figure 3-5) or Problem Summary (Figure 3-6) dialog boxes to quickly view all alarms and problem conditions that exist on your system. Figure 3-5. Alarm Summary Dialog Box VST314.vsd Figure 3-6. Problem Summary Dialog Box VST315.vsd HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 11 Overview of Monitoring and Recovery Recovery Operations for Problems Detected by OSM Suppressing Problems and Alarms In certain cases, you might want to acknowledge or suppress a particular problem, to stop it from propagating a known problem all the way up to the system level. That way, it will be easier to identify other problems that might occur. For more information on OSM problem management features such as deleting or suppressing alarms and suppressing problem attributes, see the OSM Service Connection User’s Guide (also available as online help within the OSM Service Connection). Recovery Operations for Problems Detected by OSM Recovery operations depend on the particular problem, of course. Methods of determining the appropriate recovery action include: • • • • Alarm Details, available for each alarm displayed in OSM, provide suggested repair actions. The value displayed by problem attributes in OSM often provide clues to recovery. EMS events, retrieved and viewed in the OSM Event Viewer, include cause, effect, and recovery information in the event details. Check the section in this guide that covers the system resource—for example, Section 11, Tape Drives: Monitoring and Recovery— for information on using the SCF and other tools to determine the cause of a problem. Then follow the directions in the Recovery Operations subsection in the relevant section. Replacing a system component that has malfunctioned is beyond the scope of this guide. For more information, contact your service provider, or refer to the Support and Service Library on page 1-12. Monitoring Problem Incident Reports The OSM Notification Director generates problem incident reports when changes occur that could directly affect the availability of resources on your Integrity NonStop server. The Incident Report List tab on the Notification Director dialog box allows you to view, sort, authorize, and reject incident reports. The Notification Director allows you to forward notifications to your service provider if your system is configured for remote dial-out. Using SCF to Monitor the System Use the Subsystem Control Facility (SCF) to display information and current status for all the devices on your system known to SCF. Some SCF commands are available only to some subsystems. The objects that each command affects and the attributes of those objects are subsystem specific. This subsystem-specific information appears in a separate manual for each subsystem. A partial list of these manuals appears in Appendix C, Related Reading. HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 12 Determining Device States Overview of Monitoring and Recovery Determining Device States This subsection explains how to determine the state of devices on your system. For example, to monitor the current state of all tape devices on your system, at an SCF prompt: -> STATUS TAPE $* Example 3-1 shows the results of the SCF STATUS TAPE $* command: Example 3-1. SCF STATUS TAPE Command 1-> STATUS TAPE $* STORAGE - Status TAPE \COMM.$TAPE0 LDev State Primary Backup PID PID 156 STOPPED 2,268 3,288 STORAGE - Status TAPE \COMM.$DLT20 LDev State Primary Backup PID PID 394 STARTED 2,267 3,295 DeviceStatus NOT READY DeviceStatus NOT READY STORAGE - Status TAPE \COMM.$DLT21 LDev State Primary Backup PID PID 393 STARTED 1,289 0,299 DeviceStatus STORAGE - Status TAPE \COMM.$DLT22 LDev State Primary Backup PID PID 392 STARTED 0,300 1,288 DeviceStatus STORAGE - Status TAPE \COMM.$DLT23 LDev State Primary Backup PID PID 391 STARTED 1,287 0,301 STORAGE - Status TAPE \COMM.$DLT24 LDev State Primary Backup PID PID 390 STARTED 6,265 7,298 STORAGE - Status TAPE \COMM.$DLT25 LDev State Primary Backup PID PID 389 STARTED 4,265 5,285 NOT READY NOT READY DeviceStatus NOT READY DeviceStatus NOT READY DeviceStatus NOT READY Some other examples of the SCF STATUS command are: -> STATUS LINE $LAM3 -> STATUS WS $LAM3.#WS1 -> STATUS WS $LAM3.* -> STATUS WINDOW $LAM3.#WS1.* -> STATUS WINDOW $LAM3.*, SEL STOPPED HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 13 Determining Device States Overview of Monitoring and Recovery The general format of the STATUS display follows. However, the format varies depending on the subsystem. subsystem STATUS object-type object-name Name object-name1 object-name2 State state state PPID nn,nnn nn,nnn BPID nn,nnn nn,nnn attr1 val1 val1 attr2 val2 val2 attr3 … val3 … val3 … where: subsystem The reporting subsystem name object-type The object, or device, type object-name The fully qualified name of the object State One of the valid object states: ABORTING, DEFINED, DIAGNOSING, INITIALIZED, SERVICING, STARTED, STARTING, STOPPED, STOPPING, SUSPENDED, SUSPENDING, and UNKNOWN PPID The primary processor number and process identification number (PIN) of the object BPID The backup processor number and PIN of the object attrn The name of an attribute of the object valn The value of that object attribute SCF Object States Table 3-3 lists and explains the possible object states that the SCF STATUS command can report. Table 3-3. SCF Object States (page 1 of 2) State Substate Explanation ABORTING The object is being aborted. The object is responding to an ABORT command or some type of malfunction. In this state, no new links are allowed, and drastic measures might be underway to reach the STOPPED state. This state is irrevocable. DEFINED One of the generally defined possible conditions of an object with respect to the management of that object. DIAGNOSING The object is in a subsystem-defined test mode entered through the DIAGNOSE command. INITIALIZED The system has created the process, but it is not yet in one of the operational states. HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 14 Determining Device States Overview of Monitoring and Recovery Table 3-3. SCF Object States (page 2 of 2) State Substate Explanation SERVICING SPECIAL The object is being serviced or used by a privileged process and is inaccessible to user processes. TEST The object is reserved for exclusive testing. STARTED The object is logically accessible to user processes. STARTING The object is being initialized and is in transition to the STARTED state. STOPPED CONFIG-ERROR The object is configured improperly. DOWN The object is no longer logically accessible to user processes. HARDDOWN The object is in the hard-down state or is physically inaccessible due to a hardware error. INACCESSIBLE The object is inaccessible to user processes. PREMATURETAKEOVER The backup input/output (I/O) process was asked to take over for the primary I/O process before it had the proper information. RESOURCEUNAVAILABLE The input/output (I/O) process could not obtain a necessary resource. UNKNOWNREASON The input/output (I/O) process is down for an unknown reason. STOPPING The object is in transition to the STOPPED state. No new links are allowed to or from the object. Existing links are in the process of being deleted. SUSPENDED The flow of information to and from the object is restricted. (It is typically prevented.) A subsystem must clearly distinguish between the type of information that is allowed to flow in the SUSPENDED state and that which normally flows in the STARTED or STOPPED state. In the SUSPENDED state, the object must complete any outstanding work defined by the subsystem. SUSPENDING The object is in transition to the SUSPENDED state. The subsystem must clearly define the nature of the restrictions that this state imposes on its objects. UNKNOWN The object’s state cannot be determined because the object is inaccessible. HP Integrity NonStop NS-Series Operations Guide —529869-005 3- 15 Overview of Monitoring and Recovery Automating Routine System Monitoring Automating Routine System Monitoring You can automate many of the monitoring procedures. Automation saves you time and helps you to perform many routine tasks more efficiently. Your operations environment might be using TACL macros, TACL routines, or command files to perform routine system monitoring and other tasks. These items allow you to run many procedures so that you can quickly determine system status, produce reports, or perform other common tasks. The TACL Reference Manual contains an example that you can adapt to automate system monitoring. Example 3-2 contains an example of a command file you can use or adapt to check many of the system elements: 1. To create a command file named SYSCHK that will automate system monitoring, type the text shown in Example 3-2 into an EDIT file. Example 3-2.

What Is the Event Management Service (EMS)? The Event Management Service (EMS) is a collection of processes, tools, and interfaces that support the reporting and retrieval of event information. Information retrieved from EMS can help you to: • • • • • • Monitor your system or network environment Analyze circumstances that led up to a problem Detect failure patterns Adjust for changes in the run-time environment Recognize and handle critical problems Perform many other tasks required to maintain a productive computing operation Tools for Monitoring EMS Event Messages To view EMS event messages for an Integrity NonStop server, use one of these tools: • • • • OSM Event Viewer EMSDIST ViewPoint Web ViewPoint HP Integrity NonStop NS-Series Operations Guide —529869-005 4 -1 OSM Event Viewer Monitoring EMS Event Messages OSM Event Viewer The OSM Event Viewer is a browser-based event viewer. The OSM Event Viewer allows you to retrieve and view events from any EMS formatted log files ($0, $ZLOG, or an alternate collector) for rapid assessment of operating system problems. To access the OSM Event Viewer, refer to Launching OSM Applications on page 1-11. For details on how to use the OSM Event Viewer, refer to the online help. EMSDIST The EMSDIST program is the object program for a printing, forwarding, or consumer distributor, any of which you can start with a TACL RUN command. This guide does not describe using EMSDIST. For more information, see the Guardian User’s Guide. ViewPoint ViewPoint displays event messages about current or past events occurring anywhere in the network on a set of block-mode events screens. The messages can be errors, failures, warnings, and requests for operator actions. The events screens allow operators to monitor significant occurrences or problems in the network as they occur. Critical events or events requiring immediate action are highlighted. Web ViewPoint Web ViewPoint, a browser-based product, accesses the Event Viewer, Object Manager, and Performance Monitor subsystems. Web ViewPoint monitors and displays EMS events; identifies and lists all supported subsystems; manages NonStop server subsystems and user applications in a secure, automated, and customizable way; monitors and graphs performance attributes and trends; investigates and displays most active system processes; and offers simple navigation and a point-and-click command interface.

It gives a brief example of monitoring each type of process and provides information about the commands available for recovery operations. Types of Processes Three types of processes are of major concern to a system operator of an Integrity NonStop NS-series server: • • • System processes I/O processes (IOPs) Generic processes System Processes A system process is a privileged process that is created during system load and exists continuously for a given configuration for as long as the processor remains operable. Examples of system processes include the memory manager, the monitor, and the I/O control processes. HP Integrity NonStop NS-Series Operations Guide —529869-005 5 -1 Processes: Monitoring and Recovery I/O Processes (IOPs) I/O Processes (IOPs) An I/O process (IOP) is a system process that manages communications between a processor and I/O devices. IOPs are often configured as fault-tolerant process pairs, and they typically control one or more I/O devices or communications lines. Each IOP is configured in a maximum of two processors, typically a primary processor and a backup processor. An IOP provides an application program interface (API) that allows access to an I/O interface. A wide area network (WAN) communications line is an example of an I/O interface. IOPs configured using the SCF interface to the WAN subsystem manage the input and output functions for the ServerNet wide area network (SWAN) concentrator. Examples of IOPs include, but are not limited to, line-handler processes for Expand and other communications subsystems. Generic Processes Generic processes are configured by the SCF interface to the Kernel subsystem. They can be configured in one or more processors. Although sometimes called systemmanaged processes, generic processes can be either system processes or usercreated processes. Any process that can be started from a TACL prompt can be configured as a generic process. Generic processes can be configured to have persistence; that is, to automatically restart if stopped abnormally. Examples of generic processes: • • The $ZZKRN Kernel subsystem manager process Other generic processes controlled by $ZZKRN; for example: ° ° ° ° ° The $ZZSTO storage subsystem manager process ° The $FCSMON fibre channel storage monitor The $ZZWAN wide area network (WAN) subsystem manager process QIO processes OSM server processes The $ZZLAN ServerNet LAN Systems Access (SLSA) subsystem manager process For more information, refer to the SCF Reference Manual for the Kernel Subsystem. HP Integrity NonStop NS-Series Operations Guide —529869-005 5 -2 Monitoring Processes Processes: Monitoring and Recovery Monitoring Processes This subsection briefly provides examples of some of the tools available to monitor processes. For some processes, such as IOPs, monitoring is more fully discussed in other manuals. In general, use this method to monitor processes: 1. Develop a list of processes that are crucial to the operation of your system. 2. Determine how each of these processes is configured. 3. Use the appropriate tool to monitor the process. Monitoring System Processes Check that the system processes are up and running in the processors as you intended.

Monitoring Generic Processes Because generic processes are configured using the SCF interface to the Kernel subsystem, you specify the $ZZKRN Kernel subsystem manager process when monitoring a generic process. These SCF commands are available for monitoring $ZZKRN and other generic processes: INFO Displays configuration information for the specified objects NAMES Displays a list of subordinate object types and names for the specified objects STATUS Displays current status information about the specified objects Monitoring the Status of $ZZKRN To monitor the status of the $ZZKRN Kernel subsystem manager process, at a TACL prompt: > SCF STATUS SUBSYS $ZZKRN This example shows the output produced by this command: 1 -> STATUS SUBSYS $ZZKRN NONSTOP KERNEL - Status SUBSYS \COMM.$ZZKRN Name State \COMM.$ZZKRN STARTED Processes (conf/strd) ( 25/22 ) Monitoring the Status of All Generic Processes To monitor the status of all generic processes controlled by $ZZKRN, at a TACL prompt: > SCF STATUS PROCESS $ZZKRN.#* HP Integrity NonStop NS-Series Operations Guide —529869-005 5 -4 Monitoring Generic Processes Processes: Monitoring and Recovery This example shows the output produced by this command: 1-> STATUS PROCESS $ZZKRN.#* NONSTOP KERNEL - Status PROCESS \DRP25.$ZZKRN.#CLCI-TACL Symbolic Name Name State CLCI-TACL MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON MSGMON OSM-APPSRVR OSM-CIMOM OSM-CONFLH-RD OSM-OEV QATRAK QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON QIOMON RTACL SCP SP-EVENT TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP TFDSHLP $CLCI $ZIM00 $ZIM01 $ZIM02 $ZIM03 $ZIM04 $ZIM05 $ZIM06 $ZIM07 $ZIM08 $ZIM09 $ZIM10 $ZIM11 $ZIM12 $ZIM13 $ZIM14 $ZIM15 $ZOSM $ZCMOM $ZOLHI $ZOEV $TRAK $ZM00 $ZM01 $ZM02 $ZM03 $ZM04 $ZM05 $ZM06 $ZM07 $ZM08 $ZM09 $ZM10 $ZM11 $ZM12 $ZM13 $ZM14 $ZM15 $RTACL $ZNET $ZSPE $ZTH00 $ZTH01 $ZTH02 $ZTH03 $ZTH04 $ZTH05 $ZTH06 $ZTH07 $ZTH08 $ZTH09 $ZTH10 $ZTH11 $ZTH12 STOPPED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STOPPED STOPPED STOPPED STOPPED STOPPED STARTED STARTED STOPPED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STOPPED STOPPED STOPPED STOPPED STOPPED STOPPED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STOPPED STOPPED Sub Primary PID None 0 ,306 1 ,291 2 ,285 3 ,280 4 ,280 5 ,280 6 ,280 7 ,280 8 ,280 9 ,280 10,280 None None None None None 2 ,292 2 ,294 None 2 ,290 0 ,17 0 ,290 1 ,280 2 ,280 3 ,279 4 ,279 5 ,279 6 ,279 7 ,279 8 ,279 9 ,279 10,279 None None None None None None 0 ,14 0 ,309 0 ,310 1 ,292 2 ,286 3 ,281 4 ,281 5 ,281 6 ,281 7 ,281 8 ,281 9 ,281 10,281 None None Backup PID None None None None None None None None None None None None None None None None None None 3 ,288 None None None None None None None None None None None None None None None None None None None None 1 ,13 None None None None None None None None None None None None None None Owner ID 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 HP Integrity NonStop NS-Series Operations Guide —529869-005 5 -5 Recovery Operations for Processes Processes: Monitoring and Recovery TFDSHLP TFDSHLP TFDSHLP ZEXP ZHOME ZLOG ZZKRN ZZLAN ZZSCL ZZSMN ZZSTO ZZWAN $ZTH13 $ZTH14 $ZTH15 $ZEXP $ZHOME $ZLOG $ZZKRN $ZZLAN $ZZSCL $ZZSMN $ZZSTO $ZZWAN STOPPED STOPPED STOPPED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED STARTED None None None 0 ,13 0 ,289 0 ,308 0 ,293 0 ,292 1 ,290 1 ,289 0 ,291 2 ,296 None None None 1 ,15 1 ,295 1 ,329 1 ,319 1 ,297 2 ,279 2 ,282 1 ,320 3 ,289 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 255,255 In nearly all circumstances, items that are essential to system operations that must be running at all times restart automatically if they are stopped for any reason while the NonStop Kernel operating system is running. Some OSM processes stop after executing a macro that runs during system load or during the reload of processor 0 or 1. Those processes include $ZOLHI. Optionally, you can also configure other processes such as the Expand subsystem manager process, $ZEXP, and the Safeguard monitor process, $ZSMP, as generic processes. Recovery Operations for Processes For recovery operations on generic processes, use the SCF interface to the Kernel subsystem and specify the PROCESS object. These SCF commands are available for controlling generic processes: ABORT Terminates operation of a generic process. This command is not supported for the subsystem manager processes. START Initiates the operation of a generic process. Generic processes that are configured to be persistent usually do not require operator intervention for recovery. In most circumstances, persistent generic processes restart automatically. For recovery operations on IOPs, refer to the WAN Subsystem Configuration and Management Manual, the SWAN Concentrator and WAN Subsystem Troubleshooting Guide, and the Expand Configuration and Management Manual. For recovery operations on system processes, refer to the Guardian User’s Guide.

Communications Subsystems The software that provides users of Integrity NonStop systems with access to a set of communications services is called a communications subsystem. Because connectivity is an important part of online transaction processing (OLTP), HP offers a variety of communications products that support a wide range of applications. Communication between specific devices or networks is typically achieved using several communications products or subsystems. These products are related as components in a layered structure. To accomplish the required connection, higher-level components—for example, NonStop TCP/IP processes—use the services of lowerlevel components such as the ServerNet LAN Systems Access (SLSA) subsystem. The same higher-level component can often use any of several lower-level components; thus, the Expand subsystem—which consists of multiple processes on a node—can use the NonStop TCP/IP subsystem, the X.25 Access Method (X.25 AM), HP Integrity NonStop NS-Series Operations Guide —529869-005 6 -1 Communications Subsystems: Monitoring and Recovery Local Area Networks (LANs) and Wide Area Networks (WANs) or other communication interface options to provide data transmissions over local area networks (LANs) or wide area networks (WANs), respectively. Similarly, multiple higher-level components can use the services of a single lower-level component. Local Area Networks (LANs) and Wide Area Networks (WANs) Two important communications interfaces for LANs and WANs on Integrity NonStop servers are the SLSA subsystem and the WAN subsystem. The SLSA subsystem supports parallel LAN I/O operations, allowing Integrity NonStop NS-series servers to communicate across the ServerNet fabrics and access Ethernet devices through various LAN protocols. SLSA also communicates with the appropriate adapter type over the ServerNet fabrics. Adapters supported on Integrity NonStop systems include: • • Gigabit Ethernet 4-port adapter (G4SA) Fibre Channel ServerNet adapter (FCSA) (for the Storage subsystem) I/O adapter module (IOAM) enclosures enable I/O operations to take place between Integrity NonStop servers and some Fibre Channel storage devices. See the Modular I/O Installation and Configuration Guide for more information. Adapters supported on NonStop S-series servers that can be accessed through Expand over IP, include: • • • • • • • ATM 3 ServerNet adapter (ATM3SA) Ethernet 4 ServerNet adapter (E4SA) Fast Ethernet ServerNet adapter (FESA) Gigabit Ethernet ServerNet adapter (GESA) Gigabit Ethernet 4-Port ServerNet adapter (G4SA) Multifunction I/O board (MFIOB) in the processor multifunction (PMF) customerreplaceable unit (CRU) and I/O multifunction (IOMF) CRU Token-Ring ServerNet adapter (TRSA) For further information, refer to the Introduction to Networking for NonStop NS-Series Servers. In addition to the adapters, the SLSA subsystem supports these objects: • • • • • Processes Monitors ServerNet addressable controllers (SACs) Logical interfaces (LIFs) Filters HP Integrity NonStop NS-Series Operations Guide —529869-005 6 -2 Communications Subsystems: Monitoring and Recovery • Local Area Networks (LANs) and Wide Area Networks (WANs) Physical interfaces (PIFs) Processes that use the SLSA subsystem to send and receive data on a LAN attached to an Integrity NonStop server are called LAN service providers. Two service providers—the NonStop TCP/IP and NonStop TCP/IPv6 subsystems and the Port Access Method (PAM)—are currently supported. They provide access for these subsystems: LAN Service Provider Subsystems Supported NonStop TCP/IP subsystem, NonStop TCP/IPv6 subsystem The Expand subsystem, which provides Expand-overIP connections. Port Access Method (PAM) Ethernet and token-ring LANs. The OSI/AS, OSI/TS, SNAX/XF, and SNAX/APN subsystems communicate with SLSA through the PAM subsystem. Processes, user applications, and subsystems that use the SLSA subsystem and related LAN providers to connect to an FCSA or G4SA attached to an Integrity NonStop NS-series server are called LAN clients. For example, the WAN subsystem is a client of the SLSA subsystem because the SLSA subsystem provides the WAN subsystem access to the ServerNet wide area network (SWAN) concentrator through the LAN. The WAN subsystem is used to control access to the SWAN concentrator. Depending on your configuration, it can be used to configure and manage both WAN and LAN connectivity for these communication subsystem objects: Object Connectivity By AM3270 Line-handler processes Asynchronous Terminal Process 6100 (ATP6100) Line-handler processes Communications Process subsystem (CP6100) Line-handler processes EnvoyACP/XF Line-handler processes Envoy subsystem Line-handler processes Expand Subsystem network control process and line-handler processes ServerNet cluster (Expand-overServerNet) Line-handler processes SNAX/APN Subsystem service manager process and line-handler processes SNAX/XF Subsystem service manager process and line-handler processes TR3271 Line-handler processes X25AM Line-handler processes You can define these communications subsystem objects as WAN subsystem devices. HP Integrity NonStop NS-Series Operations Guide —529869-005 6 -3 Communications Subsystems: Monitoring and Recovery Monitoring Communications Subsystems and Their Objects Monitoring Communications Subsystems and Their Objects Monitoring and recovery operations for communications subsystems can be complex. An error in any of the components—service providers, clients, objects, adapters, processes, and so on—can generate multiple error messages from many interdependent subsystems and processes. Analyzing and solving an error that originates in an object controlled by a LAN or a WAN often requires that you methodically gather status information about the affected services and then eliminate objects that are working normally. Detailed monitoring and recovery techniques for devices and processes related to communications subsystems are discussed in detail in the manuals for each subsystem. For more information, refer to Related Reading on page 6-13. This guide provides some basic commands you can use to identify and resolve common problems. Your most powerful tool for monitoring and collecting information about subsystem objects is the SCF facility. You can use SCF commands to get information and status for subsystem objects by name, device type, or device subtype. Subdevices are defined if a subsystem potentially operates on numerous, separately addressable objects, such as stations on a multipoint line; the line is a device, and the stations are subdevices. For a list of subsystems with their device type numbers and device subtypes, see Using SCF to Determine Your System Configuration on page 2-5. Monitoring the SLSA Subsystem This subsection describes how to obtain the status of adapters, SACs, LIFs, and PIFs. For more information on the SLSA subsystem, refer to the LAN Configuration and Management Manual. Monitoring the Status of an Adapter and Its Components 1.

The line continues normal operation while being traced, but it passes all its message traffic to a trace procedure. Tracing enables you to see the history of a communications line, including its internal processing. You can display trace files by using the commands available in the PTrace program. For information about PTrace, refer to the PTrace Reference Manual. For information about configuring a trace by using the SCF TRACE command, refer to the configuration and management manual for the communications subsystem you want to trace. HP Integrity NonStop NS-Series Operations Guide —529869-005 6- 12 Communications Subsystems: Monitoring and Recovery Recovery Operations for Communications Subsystems Recovery Operations for Communications Subsystems Some general troubleshooting guidelines are: • • Examine the contents of the event message log for the subsystem. For example, the WAN subsystem or Kernel subsystem might have issued an event message that provides information about the process failure. Event messages returned by the WAN subsystem and SWAN concentrator are described in the WANMGR and TRAPMUX sections of the Operator Messages Manual, respectively. HP provides a comprehensive library of troubleshooting guides for the communications subsystems. Attempt to analyze the problems and restart the process or object using the commands described in the appropriate manual listed in Related Reading on page 6-13. If you are unable to start a required process or object, contact your service provider. Related Reading For more information about monitoring and performing recovery operations for communications subsystems, see the manuals listed in Table 6-1. The appropriate manual to use depends on how your system is configured. For example, if a process is configured using the SCF interface to the WAN subsystem and then reconfigured with the SCF interface to another subsystem, only the SCF interface to the other subsystem would provide current information about the configuration. The SCF interface to the WAN subsystem would provide only information about the configuration before it changed. Table 6-1.

Notes. Integrity NonStop NS16000 systems support connectivity to NonStop S-series I/O enclosures, Integrity NonStop NS14000 and NS1000 systems do not. For more information, see Differences Between Integrity NonStop NS-Series Systems on page 2-2. An Integrity NonStop NS16000 system can be part of the same ServerNet cluster as NonStop S-series systems, an Integrity NonStop NS14000 system cannot be. For more information, see the ServerNet Cluster Supplement for Integrity NonStop NS-Series Servers. Integrity NonStop NS1000 systems do not support ServerNet clusters. All Integrity NonStop system I/O is performed through the ServerNet system area network (SAN). LSU logic boards connect the SAN to the replicated four-way microprocessors on Integrity NonStop systems (except for Integrity NonStop NS1000 systems, which have no LSUs; see System I/O ServerNet Connections on page 7-4). ServerNet Communications Network The ServerNet communications network is a high-speed network within an Integrity NonStop system that connects processors to each other and to peripheral controllers. This network offers the connectivity of a standard network, but it does not depend on shared resources such as interprocessor buses or I/O channels. Instead, the ServerNet communications network uses the ServerNet architecture, which is wormhole-routed, full-duplex, packet-switched, and point-to-point. This network offers low latency, low software overhead, high bandwidth, and parallel operation. In the ServerNet architecture, each processor maintains two independent paths to other processors, I/O devices, and ServerNet adapters. These dual paths can be used HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -1 ServerNet Resources: Monitoring and Recovery ServerNet Communications Network simultaneously to improve performance, and to ensure that no single failure disrupts communications among the remaining system components. A ServerNet adapter provides the interface between a ServerNet fabric and the Fibre Channel and Ethernet links. A ServerNet adapter contains a ServerNet bus interface (SBI) and one or more ServerNet addressable controllers (SACs). Integrity NonStop NS16000 ServerNet Connectivity An Integrity NonStop NS16000 system uses the ServerNet fabric for interconnections between the LSUs, p-switches, and IOAMs, enabling an Integrity NonStop system to be connected to legacy NonStop S-series enclosures. Figure 7-1 shows a logical representation of a complete system with the X and Y ServerNet fabrics. Figure 7-1. Integrity NonStop NS16000 System HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -2 ServerNet Communications Network ServerNet Resources: Monitoring and Recovery Integrity NonStop NS14000 ServerNet Connectivity ServerNet connections between I/O devices and processors depend on whether the Integrity NonStop NS14000 system has an IOAM enclosure or VIO enclosures. Figure 7-2 shows an NS14000 system with an IOAM enclosure. For more information on Integrity NonStop NS14000 systems with VIO enclosures, see Integrity NonStop NS14000 Systems on page 2-3, the NonStop NS14000 Planning Guide, or the Versatile I/O (VIO) Manual.

For more information on Integrity NonStop NS1000 systems, see the NonStop NS1000 Planning Guide, NonStop NS1000 Hardware Installation Manual, or the Versatile I/O (VIO) Manual. System I/O ServerNet Connections For Integrity NonStop NS16000 systems, ServerNet connections to the system I/O devices (storage disk and tape drive as well as Ethernet communication to networks) radiate out from the p-switches for both the X and Y ServerNet fabrics. ServerNet cables connected to the p-switch PICs in slots 10 through 13 come from the LSUs and processors. Cables connected to the PICs in slots 4 though 9 connect to one or more IOAM enclosures or to NonStop S-series I/O enclosures equipped with IOMF2 CRUs. Figure 7-3 shows the connections to the PICs in a fully populated p-switch. For Integrity NonStop NS14000 systems, see Integrity NonStop NS14000 ServerNet Connectivity on page 7-3. Like NS14000 systems, Integrity NonStop NS1000 systems use 4PSEs to provide ServerNet connections between I/O devices and processors. However, there are no LSUs; the 4PSEs connect directly to the Blade Elements. For more information, see the NonStop NS1000 Hardware Installation Manual. Figure 7-3. I/O Connections to the PICS in a P-Switch Monitoring the Status of the ServerNet Fabrics The ServerNet fabrics provide the communication paths used for interprocessor messages, for communication between processors and I/O devices, and (in the case of HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -4 ServerNet Resources: Monitoring and Recovery Monitoring the ServerNet Fabrics Using OSM ServerNet clusters) for communication between systems.The ServerNet fabrics consist of two entirely separate communication paths—the X fabric and the Y fabric. Note. If the system is a member of a ServerNet cluster, ServerNet connections to other members are accomplished by extending the ServerNet fabrics outside the system. Such external connections make up the external ServerNet fabrics. The ServerNet Cluster Manual provides additional information about monitoring the external ServerNet fabrics. To monitor the status of the ServerNet fabrics: • Use the OSM Service Connection to check the communication between processor enclosures, I/O enclosures, and systems. • Use the Subsystem Control Facility (SCF) to check the status of interprocessor communication on the X and Y fabrics. Monitoring the ServerNet Fabrics Using OSM To check the ServerNet fabrics: 1. Log on to the OSM Service Connection. 2. Expand the tree pane to locate and select the internal or external ServerNet fabric objects: a. The X and Y internal ServerNet fabric objects are located under the System and Fabric Group objects. b. The X and Y external ServerNet fabric objects are located under the ServerNet Cluster object (if your system is part of a ServerNet cluster). 3. Check the fabric objects for: a. If a fabric object icon is covered by a red or yellow triangular symbol, check the Attributes tab in the details pane for degraded attribute values. The Service State attribute is only displayed in the Attributes tab if it has a value of other than OK. If a degraded Service State is indicated, there will be an associated alarm to provide more information about the cause of the problem. b. If a bell-shaped symbol is displayed next to a fabric icon in the tree pane, select the Alarms tab from the details pane. To get more information on an individual alarm, click to select the alarm, then right-click and select Details. c. If a fabric object icon is covered by a yellow arrow, there is a problem on a subcomponent of that fabric. Expand the fabric object to locate the subcomponent object reporting the alarm or problem attribute. For Integrity NonStop NS16000 systems, under each internal fabric object, you’ll find its associated processor switch (p-switch) module and subcomponents. For Integrity NonStop NS14000 and NS1000 systems, there are no p-switches. Instead, ServerNet connectivity is provided through 4PSEs located in the IOAMs. For more information on monitoring and recovery for external fabrics, see the appropriate ServerNet cluster manual for your particular ServerNet cluster configuration and hardware. HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -5 Monitoring the ServerNet Fabrics Using SCF ServerNet Resources: Monitoring and Recovery Monitoring the ServerNet Fabrics Using SCF The SCF STATUS SERVERNET command displays a matrix for the ServerNet X fabric and a matrix for the ServerNet Y fabric. Each matrix shows the status of the paths between all pairs of processors. Use the SCF STATUS SERVERNET command to display current information about the ServerNet fabric.

Processors 2 through 15 do not exist on this system. As a result: ° The status from processors 0 and 1 to processors 2 through 15 is displayed as unavailable (UNA) in both fabrics. ° The status from processors 2 through 15 is displayed as down. HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -6 ServerNet Resources: Monitoring and Recovery Monitoring the ServerNet Fabrics Using SCF Normal ServerNet Fabric States Normal states for a path on the ServerNet fabrics can be one of: • UP The path from the processor in the FROM row to the processor in the TO column is up. The status for all ServerNet connections between existing processors in a system should be UP. • <-DOWN (for an entire row) The processor in the FROM row is down or nonexistent. If the processor in the FROM row does not exist on your system, this status is normal. Otherwise, refer to Identifying ServerNet Fabric Problems on page 7-7. • UNA (unavailable) The processor in the TO column is down or nonexistent. Therefore, the path from the processor in the FROM row to the processor in the TO column is down. If the processor in the TO column does not exist on your system, this status is normal. Otherwise, refer to Identifying ServerNet Fabric Problems on page 7-7. Identifying ServerNet Fabric Problems Depending on how your system is configured, these states for a path on the ServerNet fabrics might indicate a problem: • DIS (disabled) The ServerNet fabric is down at the TO location. As a result, the path from the processor in the FROM row to the processor in the TO column is down for receiving; that is, the processor in the TO column cannot receive from any other processor or from I/O devices. DIS overrides both UP and DN. • DN (down) The path from the processor in the FROM row to the processor in the TO column is down because the path is failing. The processor in the FROM row cannot send to the processor in the TO column. • <- DOWN (for an entire row) The processor in the FROM row is down or nonexistent. For a processor that does exist on your system, this status is abnormal. • ERROR nnn (for an entire row) The processor in the FROM row unexpectedly returned a file-system error to that ServerNet fabric. • UNA (unavailable) The path from the processor in the FROM row to the processor in the TO column is down because the processor in the TO column is down. For a processor that does exist on your system, this status is abnormal. UNA overrides all other states. HP Integrity NonStop NS-Series Operations Guide —529869-005 7 -7 ServerNet Resources: Monitoring and Recovery Related Reading Recovery Operations for the ServerNet Fabrics For most recovery operations, refer to the SCF Reference Manual for the Kernel Subsystem. Recovery Operations for a Down Disk Due to a Fabric Failure When a path to a disk drive goes down due to a ServerNet fabric failure (either the ServerNet X or Y fabric is down), the storage subsystem automatically switches the paths of the disk drive if possible, so that the disk drive remains operational. This switching might result in a disk drive being placed in the STOPPED state with a substate of HARDDOWN. You must restart any disk path that was using the fabric that went down. Otherwise the storage subsystem never attempts to use that path, which creates a potential single point of failure. For more information, refer to Recovery Operations for a Down Disk or Down Disk Path on page 10-14. Recovery Operations for a Down Path Between Processors When the status is either DIS (disabled) or DN (down), you can restart all paths between processors on the X fabric or Y fabric: > SCF START SERVERNET $ZSNET.{X|Y}.* Refer to the SCF Reference Manual for the Kernel Subsystem. Recovery Operations for a Down Processor If the status for an existing processor is <- DOWN or UNA, refer to Recovery Operations for a Processor Halt on page 9-9 for more information about recovery operations. Recovery Operations for a File-System Error For information about file-system errors, refer to the Guardian Procedure Errors and Messages Manual.

Information on ServerNet/DAs, the IOMF2 enclosure, and the I/O adapter module (IOAM) is available in NonStop S-series documentation. For information about the disk drives or tape drives supported on a ServerNet/DA for your H-series RVU, refer to the H-Series Highlights and Migration Planning Guide. Note. Starting with H06.08, new Integrity NonStop NS14000 and NS1000 servers are shipped with VIO enclosures instead of an IOAM enclosure. VIO enclosures provide the same functionality as IOAM enclosures. The monitoring and recovery principles described in this chapter are essentially the same for VIO enclosures; however, the components and OSM object names vary. For more information on VIO enclosures, see: • • • • Versatile I/O (VIO) Manual NonStop NS14000 (or NS1000) Planning Guide NonStop NS14000 (or NS1000) Hardware Installation Manual OSM Service Connection User’s Guide HP Integrity NonStop NS-Series Operations Guide —529869-005 8 -1 I/O Adapters and Modules: Monitoring and Recovery I/O Adapters and Modules I/O Adapters and Modules Beginning with Integrity NonStop systems, interprocessor communications and I/O use dual ServerNet fabrics as a common interconnect means. Input/output components usually connect to the ServerNet fabrics through ServerNet adapters that are in an I/O adapter module (IOAM) enclosure. These adapters provide the system I/O to Fibre Channel storage devices and gigabyte Ethernet communications networks. Connections to the ServerNet fabric through a NonStop S-series I/O enclosure equipped with IOMF2s provide additional ServerNet interfacing for the Integrity NonStop I/O peripherals. Even though the hardware architecture differs from one series of NonStop servers to another, the Integrity NonStop system can be networked with other NonStop systems using the same message system and the same network software. Fibre Channel ServerNet Adapter (FCSA The FCSA provides Fibre Channel connectivity to certain external devices such as disk drives contained in a disk drive enclosure that supports fibre channel disks and an Enterprise Storage System (ESS). Any connection between an Integrity NonStop system and a disk drive enclosure containing M8xxx fibre channel disks requires the services of two processes: the Fibre Channel Storage (FCS) Manager, which is part of the Storage Manager ($ZZSTO), and the FCS Monitor $FCSMON), a persistent generic process that runs in all processors. An FCS Monitor process must be running in all processors. Each of the two SACs on an FCSA can support as many as four disk drive enclosures, for a total of eight per FCSA. The FCS Manager process assigns a SAC on an FCSA to a particular instance of the FCS Monitor. Up to 10 FCSAs can be housed in an I/O adapter module (IOAM), which is mounted in an IOAM enclosure (except in Integrity NonStop NS14000 and NS1000 systems, where slot 1 is reserved for a 4-Port ServerNet Extender (4PSE)). The form factor and connection technology of IOAM enclosures differ from the standard I/O enclosures that provide direct ServerNet access to external I/O devices. A pair of ServerNet switch boards, also located in the IOAM enclosure, provide connectivity between the processors and the FCSAs. All IOAM hardware can be monitored by OSM. For information about the disk drives or tape drives supported through FCSAs for your H-series RVU, refer to the H06.nn Release Version Update. Gigabit Ethernet 4-Port Adapter (G4SA) The M8800 Gigabit Ethernet 4-port ServerNet adapter (G4SA) provides Gigabit connectivity between Integrity NonStop systems and Ethernet LANs. G4SAs are installed in slots 1 through 5 of an I/O adapter module (IOAM) (except in Integrity NonStop NS14000 and NS1000 systems, where slot 1 is reserved for a 4-Port ServerNet Extender (4PSE)). There are two IOAMs in an IOAM enclosure, so a total of 10 G4SAs can be installed in an enclosure. Although the G4SA supersedes the HP Integrity NonStop NS-Series Operations Guide —529869-005 8 -2 I/O Adapters and Modules: Monitoring and Recovery 4-Port ServerNet Extender (4PSE) Ethernet 4 ServerNet adapter (E4SA), Fast Ethernet ServerNet adapter (FESA), and the Gigabit Ethernet ServerNet adapter (GESA), it cannot be installed in a NonStop S-series enclosure. A G4SA has three primary system connections: • • • Data transfer interface (ServerNet) Maintenance entity (ME) interface Power interface The data transfer interface consists of ports to the ServerNet X and Y fabrics. The ports connect to the ServerNet addressable controller (SAC) on the adapter. If one ServerNet fabric fails, the G4SA can still be accessed using the remaining fabric. The Maintenance Entity (ME) interface contains the circuitry required to meet the maintenance system requirements of an active-logic adapter. The G4SA receives power through a shielded, high-density, metric connector module. The connector module provides attachments to the two ServerNet fabrics. G4SAs are configured and managed through the Subsystem Control Facility (SCF) interface to the ServerNet LAN Systems Access (SLSA) subsystem. The SLSA subsystem is preinstalled and preconfigured and is started during the system-load sequence. For information about the SLSA subsystem, refer to the LAN Configuration and Management Manual. 4-Port ServerNet Extender (4PSE) A component in Integrity NonStop NS14000 and NS1000 systems only, 4PSEs provide ServerNet connectivity between processors and the IOAM enclosure (functionality provided by p-switches in an Integrity NonStop NS16000 system). 4PSEs are located in slot one (and optionally slot 2) of each IOAM. They are connected to the processors through LSUs in Integrity NonStop NS14000 systems, directly to the processors (with no LSUs) in Integrity NonStop NS1000 systems. FCSAs and G4SAs can be installed in slots 2 through 5 of the two IOAMs in the IOAM enclosure for communications to storage devices and subsystems as well as to LANs. See Monitoring the 4PSEs on page 8-7. Monitoring I/O Adapters and Modules Use the Subsystem Control Facility (SCF) or the OSM Service Connection to monitor the FCSAs, G4SAs, and ServerNet/DAs.

HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -1 Processors and Components: Monitoring and Recovery Overview of the NonStop Blade Complex Overview of the NonStop Blade Complex Note. This section does not apply to Integrity NonStop NS1000 systems, which use the NSVA rather than NSAA architecture (see NonStop System Architectures on page 2-2). For more information on Integrity NonStop NS1000 systems, see Differences Between Integrity NonStop NS-Series Systems on page 2-2, the NonStop NS1000 Planning Guide, or the NonStop NS1000 Hardware Installation Manual. The basic building block of the modular NonStop advanced architecture (NSAA) compute engine is the NonStop Blade Complex, which consists of two or three processor modules called NonStop Blade Elements. Each Blade Element houses two or four microprocessors called processor elements (PEs). A logical processor consists of one processor element from each Blade Element. Although a logical processor physically consists of multiple processor elements, it is convenient to think of a logical processor as a single entity within the system. Each logical processor has its own memory, its own copy of the operating system, and processes a single instruction stream. NSAA logical processors are usually referred to simply as “processors.” All input and output to and from each NonStop Blade Element goes through a logical synchronization unit (LSU). The LSU interfaces with the ServerNet fabrics and contains logic that compares all output operations of a logical processor, ensuring that all NonStop Blade Elements agree on the result before the data is passed to the ServerNet fabrics. A processor with two NonStop Blade Elements comprise the dual modular redundant (DMR) NonStop Blade Complex, which is also referred to as a duplex system. This duplex system provides data integrity and system availability that is comparable to NonStop S-series systems, but at considerably faster processing speeds. Three NonStop Blade Elements plus their associated LSUs make up the triple modular redundant (TMR) NonStop Blade Complex, which is referred to as a triplex system. The triplex system provides the same processing speeds as the duplex system while also enabling hardware fault recovery that is transparent to all but the lowest level of the NonStop operating system (OS). In the event of a processor fault in either a duplex or triplex system, the failed component within a NonStop Blade Element (processor element, power supply, and so forth) can be replaced while the system continues to run. A single Integrity NonStop system can have up to four NonStop Blade Complexes for a total of 16 processors. Processors communicate with each other and with the system I/O over dual ServerNet fabrics. A ServerNet fabric is a complex web of links that provide a large number of possible paths from one point to another. Two communications fabrics, the X and Y ServerNet fabrics, provide redundant, fault-tolerant communications pathways. If a hardware fault occurs on one of the ServerNet fabrics, communications continues on the other with hardware fault recovery transparent to all but the lowest level of the OS. Figure 9-1 is an overview of the modular NSAA and shows one NonStop Blade Complex with four processors, the I/O hardware and the ServerNet fabrics. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -2 Processors and Components: Monitoring and Recovery Overview of the NonStop Blade Complex Figure 9-1.

P-switches connect input/output components to the NS-series processors. I/O components usually tap into the ServerNet fabrics through ServerNet adapters in IOAMs (represented by Modular I/O blocks in the diagram). These adapters provide the system I/O to fibre channel storage devices and gigabyte Ethernet communications networks. However, P-switches also provide connectivity for legacy I/O through I/O enclosures equipped with IOMF2s (represented by S-Series I/O blocks in the diagram). Integrity NonStop NS14000 systems do not have p-switches and cannot be connected to legacy NonStop S-series I/O enclosures. For more information, see Integrity NonStop NS14000 ServerNet Connectivity on page 7-3). HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -3 Processors and Components: Monitoring and Recovery Monitoring and Maintaining Processors In summary, these terms describe the NSAA processor: Term Description Blade Complex Consists of two Blade Elements (in a duplex system) or three Blade Elements (in a triplex system) and up to four logical processors and their associated LSUs. An Integrity NonStop system includes up to four Blade Complexes. Blade Element Consists of a chassis, processor board containing two or four PEs (one representing each logical processor in the Blade Complex), memory, I/O interface board, midplane, optics adapters, fans, and power supplies. Blade Elements are mounted in a 19-inch computer equipment rack. Processor element (PE) A single Itanium microprocessor with its associated memory. A PE is capable of executing an individual instruction stream and I/O communication through fiber-optic links. Logical processor One PE from each Blade Element executing a single instruction stream. A duplex system has two PEs forming a logical processor. A triplex system has three PEs. Monitoring and Maintaining Processors To monitor processors, use OSM, the ViewSys product, and other tools. Monitoring and maintaining processors includes: • • • • • Monitoring Processors Automatically Using TFDS on page 9-4 Monitoring Processor Status Using the OSM Low-Level Link on page 9-5 Monitoring Processor Status Using the OSM Service Connection on page 9-5 Monitoring Processor Performance Using ViewSys on page 9-7 Monitoring EMS Event Messages on page 4-1 Monitoring Processors Automatically Using TFDS HP Tandem Failure Data System (TFDS) should be used to proactively monitor processors and manage processor halts. Configured and running before a halt occurs, TFDS can help determine the type of recovery operation needed and: • • • • If TFDS determines that the entire processor should be dumped be reloading, it automatically dumps, then reloads the processor. If TFDS determines that only the processor element (PE) for one Blade Element needs to be dumped, it reloads the processor, excluding that Blade Element, dumps the Blade Element, then reintegrates it back into the running processor. Collects the files necessary to analyze the problem. Sends halt information message to the EMS collector. If configured in OSM, a dial-out message is sent to HP Global Support to notify them of the halt. For more information on configuring and using TFDS, see the Tandem Failure Data System (TFDS) Manual. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -4 Processors and Components: Monitoring and Recovery Monitoring Processor Status Using the OSM LowLevel Link Monitoring Processor Status Using the OSM Low-Level Link From the OSM Low-Level Link, use the Processor Status dialog box to determine if the processors are running: 1. Log on to the OSM Low-Level Link. 2. On the toolbar, click the Processor Status button. 3. The status for all processors should be “Executing NonStop OS.” (See Figure 9-2.) If not, refer to Identifying Processor Problems on page 9-7. Figure 9-2. Processor Status Display Monitoring Processor Status Using the OSM Service Connection For Integrity NonStop NS-series systems, the OSM Service Connection displays processor-related components under Processor Complex objects in the tree pane. There can be up to four Processor Complex objects per NS-series system, for a total of 16 processors. When you expand a Processor Complex object (see Figure 9-3), you should see two or three Blade Element objects and either two or four Logical Processor objects. Under the each Blade Element object, a Blade Element Firmware object displays the firmware version information for that Blade Element. Under each Logical Processor object, a Processor Components object represents (provides attributes and actions for) the processor’s associated logical synchronization unit (LSU) and processor elements (PEs). From the processor perspective, each PE is identified as A, B, or C (to identify the Blade Element it is associated with); whereas, from the Blade Element perspective, each PE is identified as 0, 1, 2, or 3 (to identify the Logical Processor it is associated with).

OSM Representation of Processor Complex To check processor-related components using the OSM Service Connection: 1. Expand the tree pane to check all Processor Complex objects. 2. If a Processor Complex object icon contains a yellow arrow (as illustrated in Figure 9-3), expand that complex to check its subcomponents. • • If any processor subcomponent is displaying a red or yellow triangular symbol over its object icon, check the Attributes tab for degraded attribute values. If a bell-shaped alarm icon appears next to the subcomponent’s object icon, check the Alarms tab. To get details on an alarm, select, then right-click on the alarm and select Details. If a problem exists on a logical processor, the Halt Flag attribute has a value of true, and a Halt Code attribute value is displayed, refer to the Processor Halt Codes Manual. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -6 Processors and Components: Monitoring and Recovery Monitoring Processor Performance Using ViewSys Monitoring Processor Performance Using ViewSys Use the ViewSys product to view system resources online and to see information on system performance. ViewSys provides information about processor activity. Using ViewSys, you can list the processors on your system and determine their status. For more information, refer to ViewSys on page B-6. To use ViewSys to obtain information about processor activity, at a TACL prompt: > VIEWSYS A series of bar graphs that summarize processor performance statistics appears on your terminal. Note. The Measure utility also collects and displays statistics about system performance and the performance of processors and other system components. Operations management personnel often use this utility to help fine-tune and balance a system. For instructions on using this utility, refer to the Measure User’s Guide and the Measure Reference Manual. After the first ViewSys screen appears, press F1 to view processor busy statistics: EXIT - F16 | Alt-F6 VIEWSYS HELP - BREAK | ctrl-Scroll Lock system: \SAGE process: $VIEW pid1: 07,70 pid2: terminal: $TERM1 delay: 3.00 seconds mode: CURRENT last sample: July 2, 1993 11:06:54.07 CPU BUSY 0---1---2---3---4---5---6---7---8---9---100% BUSY cpu 00 32 cpu 01 51 cpu 02 42 cpu 03 72 cpu 04 10 cpu 05 89 cpu 06 8 cpu 07 29 cpu 08 23 To exit ViewSys, press F16. Identifying Processor Problems Processor problems include system hangs, processor halts, OSM alarms. Processor or System Hangs A processor hang occurs when system components wait for an event that is not going to happen. An unexpected event such as a deadlock (two or more processors waiting for each other) might have occurred. In some cases, the entire system might hang, or be unresponsive. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -7 Processors and Components: Monitoring and Recovery Processor Halts Processor Halts When certain errors occur (such as when data integrity is at risk), the operating system cannot correct the problem and must halt all application and system processes running in the associated processor. The remaining running processors in the system each send a message, reporting the halted processor as down. The other processors in the system, including the backup to the halted processor, are not affected by the errors that caused the processor to halt unless they are freeze-enabled. Two types of processor halts display a processor halt code in the Processor Status dialog box: • A halt instruction results in a processor halt. When the operating system detects a millicode or software error that it cannot correct, it can execute a halt instruction to suspend all application and system processes running in the associated processor. The status of the halted processor becomes: Halt code = %nnnnnn Unlike a freeze instruction, a halt instruction affects only one processor. • A processor can be halted by a freeze instruction. A freeze-enabled processor can be frozen by another frozen processor. When a freeze instruction is executed, any processors that are freeze-enabled also freeze immediately. When the operating system detects a software error that it cannot correct, it can execute a freeze instruction to suspend all application and system processes running in the associated processor. The status of the frozen processor becomes: Freeze code = %nnnnnn If system freeze is enabled, the status for all other freeze-enabled processors becomes: Frozen by other processor The Processor Halt Codes Manual documents processor halt codes. Note. Do not freeze-enable a processor unless instructed to do so by your service provider. OSM Alarms and Attribute Values When the OSM Service Connection displays processor-related alarms or problem attributes, the alarm and attribute details often indicate the appropriate recovery action. Recovery actions might call for: • • Trying the Recovery Operations for Processors on page 9-9. Contacting your service provider. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -8 Processors and Components: Monitoring and Recovery Recovery Operations for Processors Recovery Operations for Processors The architecture of Integrity NonStop NS-series servers offers recovery options not available in NonStop S-series. Because a logical processor has a physical processor element (PE) in each of up to three NonStop Blade Elements, in some cases, you no longer have to choose between taking the time to dump entire processors and skipping the dump to reload the system as quickly as possible. In those cases, you can reload a halted processor immediately, while excluding the PE for one Blade Element, then dump that excluded PE before reintegrating the Blade Element into the running processor. Note. The parts of this section that do not apply to Integrity NonStop NS1000 systems include all references to processor elements (PEs) the RELOAD command OMITBLADE option. For more information on Integrity NonStop NS1000 systems, see Differences Between Integrity NonStop NS-Series Systems on page 2-2, the NonStop NS1000 Planning Guide, or the NonStop NS1000 Hardware Installation Manual.

Configured and running before a halt occurs, TFDS can help determine and perform the type of recovery operation needed (see Monitoring Processors Automatically Using TFDS on page 9-4). For information on configuring and using TFDS, see the Tandem Failure Data System (TFDS) Manual. If all processors have halted (the system is down), TFDS cannot perform an automatic dump or reload. You must load the system, as described in Performing a System Load From a Specific Processor on page 15-11. You can omit one Blade Element from the load operation, to dump after the system is running. You can also dump the remaining processors as needed—dump the entire processor before reloading, or reload and omit Blade Element to dump later. For more information, see Dumping a Processor to Disk on page 9-15. HP Integrity NonStop NS-Series Operations Guide —529869-005 9 -9 Processors and Components: Monitoring and Recovery Halting One or More Processors The best manual recovery operation for your processor halt scenario depends on the type of halt. You should record the halt information (as described in Identifying Processor Problems on page 9-7), and contact your service provider to help you determine the appropriate course of action. This section describes the various options for Dumping a Processor to Disk and Reloading a Single Processor on a Running Server that you might be directed to use. Halting One or More Processors To place a selected processor or processors in a halt state and set the status and registers of the processor or processors to an initial state: 1. Log on to the OSM Low-Level Link. 2. On the toolbar, click Processor Status button. 3. In the Processor Status dialog box, select the processor to be halted or select all the processors to halt all of them. 4. Select Processor Actions>Halt. 5. Click Perform action. 6. A message box appears and asks whether you are sure you want to perform a halt on the selected processor or processors. Click OK. Reloading a Single Processor on a Running Server Sometimes one or more processors in a running server are not operating. For information on how to determine whether a processor is operating, see Monitoring Processor Performance Using ViewSys on page 9-7. Unlike NonStop S-series, you don’t always have to wait until you dump the processor before reloading it. This section describes how, when appropriate, to exclude the processor element (PE) from one NonStop Blade Element during the reload operation, so you can get the rest of the processor running, take the dump, then reintegrate the PE back into the running processor. After you have determined that a processor is not operating, check that the processor is halted. If it needs to be halted, see Halting One or More Processors on page 9-10). Collect information about the reason for the halt (as described in Identifying Processor Problems on page 9-7) to send to your service provider along with the dump file. In the Low-Level Link Processor Status dialog box, write down the halt code and status message for the processor. Your options for reloading a processor on a running server are: • • Using TACL RELOAD to Perform Reload on page 9-11 Using the OSM Service Connection to Perform Reload on page 9-13 Following the reload, if TFDS is not configured to take the dump automatically, you can perform a dump of the omitted PE while normal operations resume on the reloaded PEs within that logical processor. See the Dumping a Processor to Disk on page 9-15. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 10 Processors and Components: Monitoring and Recovery Reloading a Single Processor on a Running Server Using TACL RELOAD to Perform Reload Run the RELOAD utility to reload the remaining processors after the first processor in a system has been brought up, or to recover a processor that has failed. The H-series RELOAD utility allows you to omit (or exclude) a Blade Element from the reload operation. This allows you get the processor running for the PEs on the other Blade Elements, take a dump of the PE on the omitted Blade Element, and then reintegrate it back into the running processor. The OMITBLADE parameter allows you to specify the Blade Element (A, B, or C) to be excluded from the reload or, used without specifying a particular Blade Element, OMITBLADE selects a Blade Element to be excluded. 1. Select File>Start Terminal Emulator. 2. From the menu, select For Startup TACL. Two OutsideView windows appear. 3. In the Enter Telnet IP Address box, type the IP address that is currently configured for your primary service connection. If the processor for the primary service connection IP address is down, type the IP address that is currently configured for your backup service connection. 4. Click OK. The OutsideView window is active, and the TACL1> prompt appears. 5. Enter the super ID (255,255) and press Enter. 6. Type the password and press Enter. A $SYSTEM STARTUP 1> prompt appears (the prompt depends on your defaults). 7. Use the RELOAD command as appropriate for your scenario. Note. If you plan to dump the PE for one Blade Element after reloading, use RELOAD with the OMITBLADE parameter. If you don’t know which Blade Element to specify, use OMITBLADE without specifying A, B, or C. RELOAD will choose an appropriate Blade Element, and reply with the letter of the Blade Element that was omitted. Use this to specify the Blade Element in the RCVDUMP command. RELOAD [ / run-option [ , run-option ] ... / ] cpu-set [; cpu-set ] ... run-option is any of the options described in the RUN[D|V] Command, in the HP NonStop TACL Reference Manual. cpu-set is a set of processors (and options) to be reloaded. Specify cpu-set as: { cpu-range } [, option, option, ... ] { ( cpu-range, cpu-range, ...) } { * } cpu-range HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 11 Processors and Components: Monitoring and Recovery Reloading a Single Processor on a Running Server is one of these: cpu cpu-cpu cpu is the processor number, an integer from 0 through 15. cpu-cpu is two processor numbers separated by a hyphen, specifying a range of processors. In a range specification, the first processor number must be less than the second. option is one of these: NOSWITCH [PRIME|NOPRIME] fabric OMITBLADE [A|B|C] $volume [.sysnn.osdir] NOSWITCH specifies that, when a processor is reloaded, there is no default autoswitch of controller ownership to the configured primary processor. [PRIME|NOPRIME] Sets up the logical processor for the reload operation. NOPRIME is the default. fabric specifies whether the X fabric or Y fabric is used for the transfer of the operating system image to the processor during the RELOAD operation. 0 = X fabric 1 = Y fabric The default option is the X fabric. OMITBLADE [A|B|C] The PE on the selected Blade Element will not be reloaded when other PEs in that logical processor are reloaded. If you do not provide an argument (A or B or C) the system will choose a Blade Element to omit. $volume [.sysnn.osdir] specifies a volume other than $SYSTEM where the operating system image (sysnn.osdir) to be used for reloading the processor is located. Depending on your requirements, this specification could take the form of $volume or $volume.sysnn.osdir or sysnn.osdir or osdir. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 12 Processors and Components: Monitoring and Recovery Reloading a Single Processor on a Running Server * specifies that all failed processors should be reloaded. 8. Check the OutsideView window for status messages, which will report successes or errors during the load. Monitor the state of the processor you are loading until it is executing the NonStop Kernel operating system. 9. If the load fails, check the parameters and reload the processor. If the load fails again, contact your service provider. Using the OSM Service Connection to Perform Reload The OSM Service Connection provides a Reload action on the Logical Processor object. You can perform the action on a single or multiple processors. The OSM action lets you reload an entire processor or omit a Blade Element from the reload action so you can dump the PE for that Blade Element before reintegrating it into the running processor. • To reload a single processor: 1. Select the Logical Processor object for the processor you want to reload. 2. Right-click and select Actions. 3. Select Reload, click Perform action. 4. Click OK to the dismiss the confirmation dialog box. 5. In the Logical Processor Reload Parameters dialog box, select the appropriate options. See OSM online help for information about the options. 6. Click OK. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 13 Processors and Components: Monitoring and Recovery • Recovery Operations for a System Hang To reload a multiple processors, use the Multi-Resource Actions dialog box (available from the Display menu of the OSM Service Connection). 1. In the Multi-Resource Actions dialog box, select Logical Processor from the Resource Types list. All Logical Processors in the system will be displayed in the right-hand pane. 2. Select Reload from the Action list under Selection Criteria. 3. From the list of Logical Processors, select the ones you want to reload and click Add to move them to the lower list (you can select and add one at a time, or Ctrl-click to select more than one). 4. Once all the processors you want to reload (and only those you want to reload) are in the lower list, click Perform Action. 5. Click OK to the dismiss the confirmation dialog box. 6. In the Logical Processor Reload Parameters dialog box (same dialog box pictured in procedure for reloading a single processor), select the appropriate options. See OSM online help for information about the options. 7. Click OK. Recovery Operations for a System Hang If a system hang occurs on an NS-series server, you no longer have to choose between taking the time to dump the system or quickly loading the system without the benefit of getting the dump information. You can now load processor 0 or 1 while excluding one processor element (PE) in that processor. This allows you to reload the rest of the processors, get the system running as soon as possible, then take a dump of the PE that was excluded from the load operation to send to your service provider for analysis of the problem. After a system hang has occurred, under the direction of your service provider, recovery operations might include: 1. Enabling System Freeze (see Enabling/Disabling Processor and System Freeze on page 9-15). 2. Freezing the System and Freeze-Enabled Processors on page 9-15. 3. Start the system by loading Processor 0 or 1, as described in Performing a System Load From a Specific Processor on page 15-11. You can omit one Blade Element from the load operation, to dump after the system is running. You can also dump the remaining processors as needed—dump the entire processor before reloading, or reload and omit Blade Element to dump later. For more information, see Dumping a Processor to Disk on page 9-15. 4. Disabling System Freeze (see Enabling/Disabling Processor and System Freeze on page 9-15). HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 14 Processors and Components: Monitoring and Recovery Enabling/Disabling Processor and System Freeze Enabling/Disabling Processor and System Freeze Caution. Enabling Processor Freeze and System Freeze should only be done by, or under the direction of, your service provider. When System Freeze is enabled and one freeze-enabled processor halts, all other freeze-enabled processors in the system also halt. When enabled, ServerNet disruptions such as cable replacement or CRU/FRU insertion can generate a system freeze. If System Freeze is enabled, disable it before performing a service operation. The system and processors are freeze-disabled by default. You can check the current state through the following attributes: • • System Freeze—In the OSM Low-Level Link, under the System object, the System Freeze attribute indicates whether System Freeze is currently Enabled or Disabled. Processor Freeze—Check either: ° In the OSM Low-Level Link, under each Processor object, the Processor Freeze attribute indicates whether Processor Freeze is currently Enabled or Disabled for that processor. ° In the OSM Service Connection, under each Logical Processor object, the Processor Freeze State attribute indicates whether Processor Freeze is currently Enabled or Disabled for that processor. To enable or disable System Freeze, use Enable System Freeze action, located under the System object in the OSM Low-Level Link. After a System Freeze action is performed, the System Freeze attribute is automatically set back to Disabled. To enable or disable Processor Freeze, you can use either the OSM Low-Level Link or the OSM Service Connection: • • In the OSM Low-Level Link, use the Enable Freeze or Disable Freeze actions, located under the Processor object. In the OSM Service Connection, use the Enable Processor Freeze or Disable Processor Freeze actions, located under the Logical Processor object. Freezing the System and Freeze-Enabled Processors In the OSM Low-Level Link, under the System object, perform the System Freeze action. This action halts all freeze-enabled processors in the system. Confirm that the action success Processor Freeze State for each processor is now Enabled. In addition to the attribute values described earlier, in the LLL Processor Status dialog box, each processor should now display an “F” appears next to its name Dumping a Processor to Disk Dump options for NonStop NS-series servers are different than for NonStop S-series servers. While dumping to tape is not option for NS-series, there are many new options for dumping an entire processor or just the processor element (PE) needed. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 15 Processors and Components: Monitoring and Recovery Dumping a Processor to Disk For automatic dumping and reloading of halted processors, use the HP Tandem Failure Data System (TFDS). To dump automatically, TFDS must be configured on the system before the halt occurs. However, you can also bring up TFDS following a halt and use the TFDSCOM command ANALYZE CPU to obtain information about the failure. If you did not have TFDS configured to take the processor dump, you can use the RCVDUMP utility to take the dump. • If your service provider determines that a processor halt is divergence-related, you might be directed to dump the entire processor before reloading it. In this case, use the RCVDUMP command, as follows: ° ° Use BLADE ALL parameter option. Do not specify ONLINE or PARALLEL parameters. See Using RCVDUMP to Dump a Processor to Disk on page 9-17. • If your service provider determines that a processor halt is not divergence-related, you might be directed to reload the processor while excluding the PE for one Blade Element, which is then dumped before being reintegrated. In this case, perform the reload (see Reloading a Single Processor on a Running Server on page 9-10), then use the RCVDUMP command as follows: ° If more than one Blade Element is in the Stopped state, use the BLADE parameter and specify the bladeId (A, B, or C) of the PE to be dumped. (If only one Blade Element is in the Stopped state, it is not necessary to use the BLADE parameter.) ° Specify the PARALLEL parameter. See Using RCVDUMP to Dump a Processor to Disk on page 9-17. • • If a dump is to be taken following a system load, as described in Performing a System Load From a Specific Processor on page 15-11, options for taking dumps include: ° After the processor (0 or 1) has been loaded with a Blade Element omitted, use RCVDUMP with the PARALLEL option. ° You can dump any of the remaining processors either by dumping the entire processor before reloading them (use RCVDUMP without specifying the ONLINE or PARALLEL options), or reload with a Blade Element omitted, then dump that Blade Element using RCVDUMP with the PARALLEL option. If you are directed to dump a single PE that is running, use the RCVDUMP command, as follows: ° ° Specify the ONLINE parameter. Do not specify the Blade ID (RCVDUMP will choose the first running PE). See Using RCVDUMP to Dump a Processor to Disk on page 9-17. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 16 Processors and Components: Monitoring and Recovery Dumping a Processor to Disk Before You Begin • • • You must have a second processor connected to a terminal or workstation with a running command interpreter. The processor in which the TACL command interpreter is running performs the dump. If dumpfile already exists, it must be empty. (Its end-of-file pointer, or EOF, must be zero.) You must not prime or reset the processor before performing a processor dump. To prepare for a disk dump: 1. Verify that a disk is available with enough space to store the dump. A processor dump requires 256 extents. Each extent should equal slightly more than 1/256 the size of the processor memory. For example, for a processor with 256 megabytes of main memory, you need 256 extents of at least 512 pages each. 2. To empty an existing dumpfile: > FUP PURGEDATA dumpfile A processor dump can be made to one, two, or three files, with file names ending with an A, B, or C to designate which Blade Element the processor element was dumped from. Using RCVDUMP to Dump a Processor to Disk The RCVDUMP command has several new parameters for Integrity NonStop systems. See Dumping a Processor to Disk on page 9-15 for how they might be used for some possible dump scenarios. The parallel parameter enables you to dump and reload individual physical processors without affecting the continuing operation of the other processor elements in that logical processor grouping. To dump a processor to disk on a running system: 1. Log on to a TACL session as the super ID (255,255). 2. At a TACL prompt, run the RCVDUMP utility, choosing the parameters and options appropriate for your scenario: RCVDUMP filename, cpuNum [, BLADE bladeId] [, START startAddress][, END endAddress] [, ONLINE | PARALLEL] filename is the name of the disk file to which the dump is to be written. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 17 Processors and Components: Monitoring and Recovery Dumping a Processor to Disk cpuNum is the number of the logical processor from which a processor element is to be dumped. Specify cpuNum as an integer in the range from 0 through 15. BLADE bladeId is the identification of the Blade Element from which the processor element is to be dumped. Valid values are A or B or C or ALL. Note that ALL may not be used with the parallel method of dumping. START n... is the byte address where the dump will start. The default value is 0. END n... is the byte address where the dump will stop. Using a value of -1 is the same as specifying the end of memory. The default value is -1. ONLINE If this option is specified, a dump can be taken of a processor while it is running. You may use either PARALLEL or ONLINE but not both. PARALLEL If this option is specified, a dump may be taken of a single processor element while the other PEs in that logical processor are reloaded and continue normal operations. You may use either PARALLEL or ONLINE but not both. For more information, see the HP NonStop TACL Reference Manual. 3. Monitor the dump to make sure that it finishes successfully: a. Wait for this message to appear: CPU n has been dumped to dumpfile b. Check the size of dumpfile to verify that the end-of-file pointer (EOF) is not equal to zero. > FUP INFO dumpfile When a processor is dumped to disk, the RCVDUMP utility begins copying the dump in a compressed format from the specified processor into a disk file called dumpfile. If dumpfile does not exist, the RCVDUMP utility creates it. As the dump proceeds, the status of the processor being dumped changes in the Processor Status dialog box to indicate that a dump is in progress. When the dump is finished, the status of the selected processor in the Processor Status dialog box changes to indicate the completion of the dump. Blade Element Reintegration Whether TFDS or RCVDUMP was used to dump the PE for an individual Blade Element, reintegration should take place automatically upon completion of the dump. HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 18 Processors and Components: Monitoring and Recovery Backing Up a Processor Dump to Tape The OSM Service Connection has a Reintegrate PE action, located under the Processor Components object, in case the automatic reintegration fails. Troubleshooting and Recovery Operations for Disk Dumps If a message indicates that the dump was not successful, repeat Dumping a Processor to Disk on page 9-13 using the other ServerNet fabric. If a halt code for the selected processor appears in the Processor Status dialog box of the OSM Low-Level Link, look it up in the Processor Halt Codes Manual for further information about the cause of failure and the appropriate recovery procedure. Backing Up a Processor Dump to Tape Back up a processor dump to tape from the compressed disk file generated by the TACL RECEIVEDUMP command (or the RCVDUMP utility): 1. Follow the instructions in Dumping a Processor to Disk on page 9-15. 2. Use the BACKUP utility to copy the processor dump to tape, as described in Section 10, Disk Drives: Monitoring and Recovery. 3. See Submitting Information to Your Service Provider on page 9-19. Replacing Processor Memory Processor memory is field-replaceable for all Integrity NonStop systems. Call your service provider. If memory units cannot be replaced, the memory board must be replaced. If the Service State attribute of a Blade Element object is not OK (see Monitoring Processor Performance Using ViewSys on page 9-7), the memory board might need to be replaced. Contact your service provider. Replacing the Processor Board and Processor Entity Processor boards and entities are field-replaceable for all Integrity NonStop systems. Call your service provider. Submitting Information to Your Service Provider To help with the analysis of a processor dump, submit a backup tape of other system configuration and operations files and some additional information. • • • Submitting Tapes of Processor Dumps on page 9-20 Submitting Tapes of Configuration and Operations Files on page 9-20 Additional Information Required by Your Service Provider on page 9-21 HP Integrity NonStop NS-Series Operations Guide —529869-005 9- 19 Processors and Components: Monitoring and Recovery Submitting Information to Your Service Provider Submitting Tapes of Processor Dumps Use a separate tape for each processor dump. For each tape you submit, record: • • The notation BACKUP to indicate a disk dump that has been backed up to tape. The file names of the files on tape (if the BACKUP, LISTALL command has been used) Submitting Tapes of Configuration and Operations Files To ensure that a processor dump is usable by your service provider, place the files listed in Table 9-1 on one backup tape using the BACKUP utility. Contact your service provider for information about any other files they might need. Table 9-1. Other Files to Submit to Your Service Provider File Description $SYSTEM.ZSYSCONF.

Disk free space is fragmented. If the disk is full, an application might go down. One disk in a mirrored pair is down. The storage subsystem generates an event message but the application continues to run. An unmirrored disk is down, or both disks in a mirrored pair are down. Users report access problems, applications go down, and the storage subsystem generates event messages. Performance problems occur due to path switches or a cache size that is too small. Users report poor application performance. Defective tracks or sectors exist. Output from SCF INFO DISK, BAD command indicates unspared defective sectors. Disk errors exceed a certain limit. Intm-errors-exceeded message Slow I/O operations exceed a certain limit. Slow-IOs-threshold-exceeded message Internal SCSI Disk Drives The most common disk drive problems on a NonStop S-series server include: • • • • Space problems such as full disks or free-space fragmentation Stopped disks Performance problems Defective tracks or sectors M8xxx Fibre Channel Disk Drives The most common disk problems on an Integrity NonStop NS-series server are intmerrors-exceeded and slow-IOs-threshold-exceeded errors on the Fibre Channel loop. Such errors are often normal. However, if they cause problems on a Fibre Channel loop, power the affected disk down and up again. This procedure can solve the problem temporarily. Unless you are a qualified service provider, you cannot perform any physical actions on disk drives. However, operators can use OSM and SCF commands.

Corrupt $SYSTEM disk Failed disk drives If both halves of your mirrored system volume become corrupted, use an alternate system disk if one is available. For how to create an alternate system disk, see the Integrity NonStop NS-Series Planning Guide. • • • • For internal SCSI disk drives: if there is no alternate system disk and you cannot load from the CONFBASE file, you might be able to perform a tape load from a system image tape (SIT) to restore the system image files to the $SYSTEM disk (SYSnn and CSSnn subvolumes). Then load that image into processor 0 or 1. A tape load reinitializes the disk directory. The disk directory is overlaid with the directory from the tape. All files on that disk are destroyed. Perform a tape load only with the advice of the Global Customer Support Center or your service provider. For M8xxx disk drives: you cannot perform a tape load from a SIT. Internal SCSI disks: the Support and Service Library on page 1-12 describes replacing disk drives. M8xxx fibre channel disks: these disks are FRUs and can be serviced or replaced only by HP-trained service personnel.

Overview of Tape Drives A new generation of multimode fibre channel (MMF) peripherals is supported on Integrity NonStop systems. Tape drives with an MMF interface are connected directly to a fibre port on an FCSA in an IOAME or VIO enclosure. Some high voltage differential (HVD) SCSI drives are also supported in the NS optical environment. These drives are connected using an M8201 fibre channel to SCSI router. The M8201 converts the FCSA MMF connection into two SCSI buses. Currently, only optical port 0 is used on the M8201. The SCSI drives are connected using 68-pin to 68-pin HVD SCSI cables. These cables have a high density connector for the M8201. Most drives supported on NonStop S-series can be connected to an Integrity NonStop NS16000 server through an IOMF2 in an IOMF enclosure. The drives can be interfaced in the same manner that is supported in S-series, either through an SNDA or a SCSI port on an IOMF2 board. OSM provides different views for drives that are connected through an FCSA versus an IOMF2. See Monitoring Tape Drives on page 11-2. HP Integrity NonStop NS-Series Operations Guide —529869-005 11-1 Tape Drives: Monitoring and Recovery Monitoring Tape Drives For further information, refer to the document on Integrity NonStop NS-Series Supported Hardware and the NonStop NS16000 Hardware Installation Manual. Monitoring Tape Drives This section describes the various methods of tape drives, which include: • • • OSM Service Connection SCF Use MEDIACOM to monitor the use of tape drives and to write tape labels. Monitoring Tape Drive Status With OSM To check the status of all tape drives on your system: 1. Log on to the OSM Service Connection. 2. In the tree pane, expand the system object and check the Tape Collection object. A yellow arrow displayed over the Tape Collection object (see Figure 11-1) indicates that a problem exists with one or more of the tape drives connected to the system. 3. Expand the Tape Collection object and select the tape drive displaying a red or yellow triangular symbol over the tape drive object or bell-shaped symbol next to the object. For an example of an FCSA-connected tape drive, see Figure 11-1; for an IOMF2-connected tape drive, see Figure 11-2. • • If a red or yellow triangular symbol is displayed over the tape drive object, check the Attributes tab for the specific attribute reporting a degraded value. If a bell-shaped symbol is displayed next to the object, select the Alarms tab, click to select the alarm, then right-click and select Details to get more information about the alarm. HP Integrity NonStop NS-Series Operations Guide —529869-005 11- 2 Tape Drives: Monitoring and Recovery Monitoring Tape Drive Status With OSM Figure 11-1. OSM: Monitoring Tape Drives Connected to an FCSA VST316.vsd 4. If an alarm or degraded conditions exist, the tape drive probably requires either: • Operator intervention. For more information, see Recovery Operations for Tape Drives on page 11-8. • Service or replacement. Contact your service provider and refer to the Support and Service Library on page 1-12 for the replacement procedure. An alternative (to the method described above) for monitoring tape drives in OSM is to use the Multi-Resource Actions dialog box (available from the Display menu). In this dialog box, select the Tape Drive object to see a list of all tape drives on the system, along with their attribute values. From this list, you can: • Sort by column headings • View Alarms (for tape drives displaying a bell-shaped alarm icon) by right-clicking on the tape drive and selecting Alarms. • Perform actions on one or more tape drives (as described in Recovery Operations Using the OSM Service Connection on page 11-8) HP Integrity NonStop NS-Series Operations Guide —529869-005 11- 3 Tape Drives: Monitoring and Recovery Monitoring Tape Drive Status With OSM Figure 11-2. OSM: Monitoring Tape Drives Connected to an IOMF2 VST317.vsd Note. All tape drives connected to a system appear under the Tape Collection object. When a IOMF2-connected tape drive uses storage routers, those objects appear under that tape drive object in the OSM tree pane hierarchy; however, fibre channel routers appear under the Monitored Service LAN Devices object (after being configured in OSM). HP Integrity NonStop NS-Series Operations Guide —529869-005 11- 4 Monitoring Tape Drive Status With SCF Tape Drives: Monitoring and Recovery Monitoring Tape Drive Status With SCF To check the status of all tape drives on your system with SCF: > SCF STATUS TAPE $* A listing similar to this one is sent to your home terminal: STORAGE - Status TAPE \MINDEN.$XTAPE LDev State Primary Backup PID PID 93 STOPPED 1,287 0,279 STORAGE - Status TAPE \MINDEN.$TAPE0 LDev State Primary Backup PID PID 99 STARTED 1,289 0,278 DeviceStatus NOT READY DeviceStatus NOT READY The data shown in the report means: LDev The logical device number State The current SCF state of the tape path SubState The current SCF substate of the tape path Primary PID The primary processor number and process identification number (PIN) of the specified device Backup PID The backup processor number and PIN of the specified device DeviceStatus The status of the device path For more information: • • SCF Object States on page 3-14 describes the possible SCF states of tape drives and other devices.

Example To obtain status information about the tape drive $TAPE0 by using SCF: > SCF STATUS TAPE $TAPE0 A listing such as this one is sent to your home terminal: STORAGE - Status TAPE \MINDEN.$TAPE0 LDev State Primary Backup PID PID 99 STARTED 1,289 0,278 DeviceStatus NOT READY HP Integrity NonStop NS-Series Operations Guide —529869-005 11- 5 Monitoring Tape Drive Status With MEDIACOM Tape Drives: Monitoring and Recovery Monitoring Tape Drive Status With MEDIACOM The MEDIACOM command STATUS TAPEDRIVE displays the current status of a tape drive. Among other things, this command tells you whether a tape is mounted on the drive, the name of the DEFINE associated with the tape, and which volume catalog and pool owns it. Note. Manual unloading of a tape is not detected by a tape drive, so information from STATUS TAPEDRIVE can be out of date. For example, STATUS TAPEDRIVE could report that a drive currently has a tape mounted when the tape was removed from the drive by the operator before the command executed. To check the status of all tape drives on your system with MEDIACOM: > MEDIACOM STATUS TAPEDRIVE A listing similar to this one is sent to your home terminal: MEDIACOM - T6028D42 (18DEC98) Creating default server. Drive Tape Tape Drive Status Name -------------------$XTAPE DOWN $TAPE0 FREE 2 tape drives returned. Tape Status ------ Label Type -------- Open Mode ------ Process Name --------------------- The DSM/Tape Catalog Operator Interface (MEDIACOM) Manual explains the fields in this output.

HP Integrity NonStop NS-Series Operations Guide —529869-005 11- 7 Tape Drives: Monitoring and Recovery Recovery Operations for Tape Drives Recovery Operations for Tape Drives You can perform recovery operations on tape drives using either the SCF interface to the storage subsystem or the OSM Service Connection. Recovery Operations Using the OSM Service Connection If the recovery operation calls for an OSM Service Connection action, you can perform an action on one or more tape drive objects. Performing an OSM Action on a Tape Drive 1. From the OSM Service Connection tree pane (the left-hand pane shown in Figure 11-1 on page 11-3): a. Expand the System and Tape Collection objects to locate the tape drive in need of attention or service. b. Right-click the tape drive object and select Actions from the menu. 2. In the Actions dialog box: a. Choose the desired action from the list of available actions. b. Click Perform action. c. Check the Action Status window to confirm successful completion of the action, or click Details for more information if the action fails. Also, check the Alarms or Attributes tab to make sure the alarm has been cleared or the degraded attribute value has returned to normal. Using the example in Figure 11-1, you might use the Start action to bring up the selected (highlighted) tape drive. If successful, the Device State should change from Hard Down to Started, and the yellow symbol in both the tree pane and Attributes tab should disappear. In many cases, there are OSM and SCF equivalents. For example, you can select the OSM Start action or the corresponding SCF START command. Performing an OSM Action on a Multiple Tape Drives 1. From the Display menu, select Multi-Resource Actions. 2. In the Multi-Resource Actions dialog box, select the Tape Drive object to display a list of all tape drives on the system. 3.

For other applications, such as SQL/MP or SQL/MX, see the appropriate documentation. Monitoring TMF This subsection explains how to check the status of TMF and the data volumes it protects. As a system operator, you might check TMF status in your routine system monitoring. You use the TMFCOM command interface to manage and operate TMF. HP Integrity NonStop NS-Series Operations Guide —529869-005 13- 1 Applications: Monitoring and Recovery Monitoring the Status of TMF Monitoring the Status of TMF To monitor TMF using TMFCOM: 1. At a TACL prompt: > TMFCOM 2. At the TMFCOM prompt: ~ STATUS TMF Note. The STATUS TMF command presents status information about the audit dump, audit trail, and catalog processes. Thus, in addition to the general TMF information, the STATUS TMF command combines information from the STATUS AUDITDUMP, STATUS AUDITTRAIL, and STATUS BEGINTRANS commands. However, information from the other STATUS commands (STATUS DATAVOLS, STATUS OPERATIONS, STATUS SERVER, and STATUS TRANSACTION) does not appear in the STATUS TMF display. A TMFCOM report summarizing the current activity of the TMF subsystem, audit trails, and the audit dump and catalog processes is displayed. For example: TMF Status: System: \SAGE, Time: 6-Jul-1994 11:08:06 State: Started Transaction Rate: 0.10 TPS AuditTrail Status: Master: Active audit trail capacity used: 55% First pinned file: $MAT1.ZTMFAT.AA000044 Reason: Active transaction(s). Current file: $MAT1.ZTMFAT.AA000045 AuditDump Status: Master: State: enabled, Status: active, Process $X545, File: $MAT2.ZTMFAT.AA000042 BeginTrans Status: Enabled Catalog Status: Status: Up For an explanation of the TMF state in this display, see TMF States on page 13-3. Monitoring Data Volumes To display information about the data volumes for which the TMF subsystem generates audit records on behalf of transactions performed on those volumes, at a TMFCOM prompt, type: ~ STATUS DATAVOLS To control which volumes are displayed, use the STATE, AUDITTRAIL, and RECOVERYMODE parameters. The normal operating state for a data volume is STARTED, which indicates that the volume is ready to process TMF transactions. Audited requests are allowed for data volumes in this state only where transaction processing is enabled within the subsystem. HP Integrity NonStop NS-Series Operations Guide —529869-005 13- 2 TMF States Applications: Monitoring and Recovery For example, to check the status of all data volumes, at a TMFCOM prompt, type: ~ STATUS DATAVOLS TMFCOM responds with output similar to: Audit Recovery Volume Trail Mode State --------------------------------------------------$DATA1 MAT Online Started $DATA2 MAT Online Started $DATA3 MAT Online Recovering $DATA4 MAT Archive Recovering $DATA5 AUX01 Online Started $DATA6 AUX01 Online Started $DATA6 AUX01 Archive Recovering TMF States The TMF subsystem can be in any of the states listed in Table 13-1.

System Response to Power Failures NonStop NS-Series Cabinets (Modular Cabinets) NonStop NS-series servers are designed to operate in a computer-room environment containing a site UPS. Without a UPS, a system will stop uncontrollably when the power is lost. An optional UPS module can be installed in a modular cabinet to provide power if no site UPS is available. If AC power to a NonStop NS-series server is lost, the system will shut down after a preset time as long as UPS power is available. If the system shuts down, it will be necessary to restart the system manually when AC power is restored. If modular cabinets lose power without a UPS, recovery of lost data will be difficult and files might be corrupted. Regardless of system power-fail scenario, if site air conditioning fails and the computer-room temperature rises, the system might shut itself down uncontrollably as each processor reaches its critical temperature. Refer to the NonStop NS-Series Site Preparation Guide. NonStop S-Series I/O Enclosures NonStop S-series I/O enclosures have internal batteries and do not require a UPS. NonStop S-series enclosures must shut down before their battery power is lost. For information about power fail for I/O enclosures, refer to the NonStop NS-Series Planning Guide. External Devices External (peripheral), devices, such as tape drives, external disk drives, LAN routers, and SWAN concentrators, are not backed up by internal batteries. External devices behave differently than a system during power failure according to the UPS support provided: No UPS Peripheral devices will fail immediately if not supported by a UPS. With a Site UPS A site UPS should support external devices until its capacity to supply power is exhausted. With an Internal UPS An optional internal UPS will not support external devices during power failure. HP Integrity NonStop NS-Series Operations Guide —529869-005 14- 2 Power Failures: Preparation and Recovery ESS Cabinets During a power failure, a ServerNet/DA remains operational during the power-fail delay time, but the external modular disk and tape subsystems attached to it do not. This type of situation could result in data-integrity problems if the system software continues processing data from an external disk drive or tape drive during a short power outage. If a power failure occurs and the processors resume operations but one or more external devices fail, data integrity problems can occur. The application programs must be resilient to such device failures. ESS Cabinets ESS cabinets require a site UPS. ESS cabinets are not powered off programatically with a power failure because they may be attached to other systems. Air Conditioning Unless the site UPS provides for maintaining air conditioning, it is possible that the temperature could rise in the computer room complicating the ability of a system to survive overheating before shutting itself down. For information about site overheating problems, refer to the NonStop NS Series Site Preparation Guide. Preparing for Power Failure To prepare for power failures, set ride-through time, configure OSM power fail support, and regularly monitor power supplies and batteries. Set Ride-Through Time Ensure that the system is set for the proper ride-through time. The default powerfail delay time for NS-series systems that are configured with rack-mounted UPSs is 30 seconds. Contact HP Expert Services for the optimum ride-through time for your system. The ride-through time is set using the SCF commands to alter the POWERFAIL_DELAY_TIME parameter. Refer to the SCF Reference Manual for the Kernel Subsystem. Configure OSM Power Fail Support You must also configure OSM power fail support by performing a Configure Power Source as UPS action for at least one processor switch power supply unit (for Integrity NonStop NS16000 systems) or one IOAM or VIO power supply unit (for Integrity NonStop NS14000 or NS1000 systems). Configuring at least one power supply as being powered by UPS in the event of a power outage causes OSM to monitor a power outage and, if the AC power is not restored before the specified ride-through time period expires, OSM initiates an orderly system shutdown. For more information, see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server or the OSM Service Connection User’s Guide. HP Integrity NonStop NS-Series Operations Guide —529869-005 14- 3 Power Failures: Preparation and Recovery Monitor Power Supplies Monitor Power Supplies Monitor power-generating equipment and run regular checks on any backup generators to make sure that you can handle extended power outages. Monitor Batteries • • • Monitoring site UPS batteries is the responsibility of the customer. OSM does not interface with a site UPS or batteries. Monitoring batteries in an internal UPS and ERM is performed using OSM. Monitor batteries in I/O enclosures using OSM. For more information on battery attributes and actions, see the OSM Service Connection online help. Maintain Batteries Make sure that all installed batteries and spare batteries are always fully charged. Correct any problems that are causing the batteries to become drained. In general, batteries are constantly charging when AC power is available to a system. When recovering from a power failure event, it will take time for the batteries to be fully charged. For different kinds of batteries: • • • Maintenance and charging of site UPS batteries is the responsibility of the customer. Information about maintenance and charging of batteries in an optional internal UPS and ERM is located in documentation that comes with the products. Information about maintenance and charging of batteries in I/O enclosures is located in the Support and Service Library for NonStop S-series servers. Spare batteries for I/O enclosures require charging every six months. Power Failure Recovery After a power failure, if AC power is restored to a NonStop NS-series server while the batteries are still holding up the system, it will not be necessary to restart the system. Resume operations. Depending on the configuration of UPS resources, power failure can last long enough to leave the system with some processors down because the batteries were drained to the point where the processors can no longer operate. In conjunction with an internal UPS, a homogeneous power off can be configured to avoid this condition. If the power failure lasts long enough to drain the batteries completely, the system Power/Fail should stop the system. When power is restored, the operator must then restart the system. HP Integrity NonStop NS-Series Operations Guide —529869-005 14- 4 Power Failures: Preparation and Recovery Procedure to Recover From a Power Failure Procedure to Recover From a Power Failure After power is restored: 1. Power on the system using OSM LLL described in Powering On a System on page 15-2. 2. Log on to the OSM Service Connection and check the status of all system components to make sure they are started. 3. Use SCF commands to check the status of external devices and, if necessary, to restart any external devices to bring them back online. Setting System Time Setting the system time is not normally required following a power failure. System time is maintained by a time-of-day battery in the p-switch, IOAM, or VIO logic board that is not affected by a power outage. If required, however, you can set the system time, either programmatically or by using the TACL command interpreter. Refer to the Guardian Procedure Calls Reference Manual or the TACL Reference Manual.

However, some procedures or recovery actions require you to start the system (perform a system load) or stop or power off the system. • Stop and then power off a system before: ° ° • An extended planned power outage for your building or computer room. Performing some major maintenance or repair operations as noted in the documentation. Stop or restart a system (without powering off) when: ° ° ° Installing an updated RVU or some software product revisions (SPRs). Performing some recovery operations as noted in the documentation. Restarting the system after the entire system has been shut down with the operating system images and files on disk still intact. Powering On a System Powering on a system delivers AC power to the system cabinets. Fans on the processor switches, processor Blade Elements, IOAM or VIO enclosures, and disk drive enclosures start turning, and air begins to circulate through the components. After the fans start to operate, most other system components begin to power on. Status light-emitting diodes (LEDs) on the system components light during a series of power-on self-tests (POSTs). Any of the LEDs can become lit briefly during the POSTs. After all the POSTs finish successfully, which might take up to 10 minutes, only the green power-on LED on each component in the system enclosures should remain lit. For more information about the LEDs, refer to Using the Status LEDs to Monitor the System on page 3-20. The method you use to power on the system depends on whether the system is in a low power state or completely powered off: • • Powering On the System From a Low Power State on page 15-3 Powering On the System From a No Power State on page 15-3 HP Integrity NonStop NS-Series Operations Guide —529869-005 15- 2 Starting and Stopping the System Powering On the System From a Low Power State Powering On the System From a Low Power State 1. Log on to the OSM Low-Level Link. 2. From the tree pane, right click the system and select actions. 3. Select Power On System. 4. If your maintenance LAN is not configured with the dynamic name service (DNS) or does not have reverse look-up, you must perform a hard reset of the maintenance entities (MEs) in each p-switch or IOAM enclosure, or the integrated maintenance entities (IMEs) in each VIO enclosure*: a. From the Log On to HP OSM Low-Level Link dialog box, select Logon with Host Name or IP Address. b. Enter the IP address of: • • • a maintenance entity (ME) in a p-switch an ME in an IOAM enclosure an IME in a VIO enclosure c. Expand the tree pane to locate the ME or IME. d. Right-click that ME or IME object and select Actions. e. Select Hard Reset. f. Click Perform Action. g. A message appears: Hard Reset action will make the current session lost. After OSM Low-Level Link completes Hard Reset action, it will log you off. Do you really want to reset the ME? h. Click OK. i. Close the Low-Level Link. j. Repeat these steps for the other ME(s) or IME. * For Integrity NonStop NS14000 and NS1000 systems, there are no p-switches. Instead, there are either two MEs in the IOAM enclosure or an IME in each of the two VIO enclosures. Powering On the System From a No Power State To power on the system when you first receive your system, you refer to the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server. To power on the system subsequently: 1. Before you power on any system enclosures, power on the external system devices and any other devices you want started when the system starts. External system devices include tape devices, Enterprise Storage Systems (ESSs), printers, and terminals. HP Integrity NonStop NS-Series Operations Guide —529869-005 15- 3 Starting and Stopping the System Powering On the System From a No Power State Refer to the documentation that accompanies the device for instructions on powering on. For example: • • You must power on Fibre Channel to SCSI Converter devices connected to your system before you power on the tape devices attached to it. The converter must be powered on first to be able to discover the tape devices as they are powered on. Maintenance switches installed outside of a modular cabinet must be powered on according to the instructions provided with the switch. 2. Locate the circuit breaker that controls the power cords connected to the system cabinets. In most case, each modular cabinet in a system powers on as soon as soon as the power is applied. In addition, these components power on when the Integrity NonStop NS-server is powered on: • • NonStop I/O enclosures connected to the system Maintenance switches installed in a modular cabinet power 3. To physically monitor power-on activity: a. Check fan activity for the processor switches, processor Blade Elements, IOAM or VIO enclosures, and disk drive enclosures. Check that the fans are turning and that you can feel air circulate through the components. b. After the POSTs finish, check that only green power-on LEDs are lit in the system components before you start the server. For more information about status LEDs, see Using the Status LEDs to Monitor the System on page 3-20. 4. After the POSTs finish, check the AC power cords. Perform this test only if you have connected redundant power cords to separate circuits: a. If you have a UPS installed, switch off the UPS outputs. b. If you do not have a UPS installed: 1. Locate the circuit breaker that controls half the power cords. 2. Switch this breaker off. c. Check that all components are still operating. Note. The maintenance switch does not have redundant power. d. Switch this breaker back on. e. Locate the other circuit breaker that controls the other half of the power cords. f. Switch this breaker off. g. Check that all components are still operating. h. Switch this breaker back on.

If any components fail during any of the power shutdowns, see Components Fail When Testing the Power on page 15-19. j. If you have a UPS installed, switch off the UPS outputs. 5. If you have a UPS installed, check that the UPS is fully charged. Then, test the UPS by turning off both circuit breakers. 6. Log on to the OSM Low-Level Link. 7. Select System Discovery. 8. Double-click the System. 9. Double-click each Group 40n; for example, Group 400. 10. Check that the logical processors are displayed. 11. Double-click each Group 1nn; for example, Group 100. 12. For each Group 1nn, check that module 2 and module 3 are displayed. 13. If any of these components are not yet displayed, wait before you start the system. 14. After the system is powered on, you must wait 5 minutes before starting the system. 15. You can now start your system as described in Starting a System on page 15-5. Starting a System Use the OSM Low-Level Link to start a system. Starting a system includes a system load from disk into the memory of one processor; followed by the reload of the remaining processors. Loading the System Perform a system load to load the NonStop operating system. Alerts • • All processors in the system must be in a halted state before you perform a system load. To perform processor dumps during a system load, see the considerations in System Load to a Specific Processor on page 15-6. Normal System Load Normally, you initiate the system load as described in Performing a System Load on page 15-9. When you choose this method: HP Integrity NonStop NS-Series Operations Guide —529869-005 15- 5 Starting and Stopping the System • • • • Loading the System Processor 0 or 1 is loaded. See System Load Paths for a Normal System Load on page 15-7. The remaining processors are primed for reload. Two startup event stream windows and two startup TACL windows are automatically launched on the system console configured to receive them. The CIIN function is enabled by default. See CIIN File on page 16-5. System Load to a Specific Processor Alternately, you can perform a system load from a specified processor. When you load the system from a specified logical processor: • • • • The other logical processors are not primed automatically. Because the processors not being loaded are not primed, you can perform processor dumps, if necessary. If you need to dump processors, refer to Section 9, Processors and Components: Monitoring and Recovery. ° Do not prime or reset all the processor elements in a logical processor until after the memory dump. ° Disable the CIIN file to prevent any processors configured to reload in that file from being reloaded. The startup event stream windows and Startup TACL windows are not launched automatically when the CIIN file is disabled. See CIIN File on page 16-5. The Processor Element Dump Setting option becomes available in the System Load dialog box. For more information about this option, see Section 9, Processors and Components: Monitoring and Recovery. You must initiate the load action as described in Performing a System Load From a Specific Processor on page 15-11. System Load Disks An Integrity NonStop NS-series system can contain multiple system disk pairs in different locations. Use the System Load dialog box to select which system disk to load from. You select the system disk from the Configuration drop-down menu. The system load disk you choose must be in the configured location, properly configured as a system disk, and contain the software configuration that you want to load. The system disk that you load from starts as $SYSTEM. Any alternate system disks start using their alternate name. After you select a system load disk, the Disk Type box indicates whether you’ve selected a Fibre Channel (FCDM) or SCSI disk. The Path window is populated with information about four load paths. You can double-click on a row to make changes. However, the changes do not persist after the dialog box is closed. HP Integrity NonStop NS-Series Operations Guide —529869-005 15- 6 Loading the System Starting and Stopping the System You can choose these system load disks: • An FCDM-Load attempts to load the system from a system disk in the disk drive enclosure connected to IOAM enclosure group 110: IOAM FCSA Disk Drive Enclosure Path Group Module Slot SAC Shelf Bay Primary 110 2 1 1 1 1 Backup 110 3 1 1 1 1 Mirror 110 3 1 2 1 1 Mirror Backup 110 2 1 2 1 1 Note. For Integrity NonStop NS14000 and NS1000 servers, Fibre Channel disks are connected to IOAMs or VIO enclosures located in group 100. For more information, see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS14000 or NS1000 server, or the Versatile I/O (VIO) Manual. • • • A SCSI-Load attempts to load the system from a disk in group, module, slot 11.1.11 of a NonStop S-series I/O enclosure. A load from $SYSTEM attempts to load the system from a disk in group, module, slot 11.1.11 of a NonStop S-series I/O enclosure, by default. You can configure additional alternate system disks to load from. To create an alternate system disk, see the NonStop NSxxxx Hardware Installation Manual for your Integrity NonStop NS16000, NS14000, or NS1000 server. Then use OSM to make the disk available in the Configuration Drop-down menu in the System Load dialog box. System Load Paths for a Normal System Load 16 paths are available for loading. Table 15-1 describes each load path in order of use. The system load task attempts to use each path until the system load is successful or all possible paths have been tried. If the system load fails along all paths, refer to Troubleshooting and Recovery Operations on page 15-18. Table 15-1.

For the system disk volume you select to load the system, CONFIG represents the system configuration database that is currently running or was last running. If you cannot load the system using Current (CONFIG), you might need to use these files to recover: • • Saved Version (CONFxxyy) is a saved system configuration file. Use this file to recover from a configuration change that causes a problem. If you cannot load the system using the CONFIG file, you can use a saved version in the form xx.yy, if one is available. For example, the CONF0205 file would be specified as 02.05. Use this method to recover from a configuration change that caused a problem (such as a system freeze). When the system starts and displays a TACL prompt, you can log on and start the rest of the system applications. Base (CONFBASE) is the most basic configuration required for system startup. Although you will probably never need to load the system from the CONFBASE file, you might need to use this file if you cannot load the system using any other method. For more information about when to use CONFSAVE or CONFBASE, see Recovering From a System Load Failure on page 15-20 HP Integrity NonStop NS-Series Operations Guide —529869-005 15- 8 Starting and Stopping the System Starting Other System Components Starting Other System Components HP recommends that you bring your system up in stages, verifying each stage, to facilitate recovery if any step fails. When the system starts, many individual devices, processes, applications, and communications lines start automatically, but others might need to be started using start up files. Follow your site’s procedures for starting your applications. • • Many processes are configured by default to be started automatically by the $ZPM persistence monitor. These processes include the Kernel subsystem, SLSA subsystem, storage subsystem, and WAN subsystem. The manager processes for these subsystem start disks, SWAN concentrators, some LAN devices, and many processes. You can use SCF to configure other processes, typically monitor or manager processes, to start automatically as generic processes when the system starts. For example, you can use the SCF interface to the Kernel subsystem to add these processes to the system configuration database: ° ° $ZEXP, the Expand manager process $ZPMON, the OSS monitor process For more information about configuring generic processes to start automatically, refer to the documentation in Related Reading on page 15-24. • You can include commands in startup command files that you invoke from a TACL prompt or another startup file. For some techniques to make startup command files run as efficiently as possible, refer to Writing Efficient Startup and Shutdown Command Files on page 16-9. Performing a System Load To perform a normal system load: 1. Verify that all processors are halted as described in Stopping the System on page 15-16. All processors in the system must be halted before you initiate a system load. 2. Log on to the OSM Low-Level Link. 3. From the OSM Low-Level Link toolbar, click Start system. 4. If you initiate a system load while processors are running, a message appears asking whether you want to proceed. If you click Yes, all the processors are halted, then the system load begins.

Reloading Processors After the system load, use one of these procedures to reload the remaining processors in the system: • • Reloading Processors Using the RELOAD Command on page 15-12 Reloading Processors Using OSM on page 15-12 To reload a halted processor and perform memory dumps, use the reload procedures in Section 9, Processors and Components: Monitoring and Recovery. Reloading Processors Using the RELOAD Command 1. From a TACL prompt, log on to the system as a super user ID (255,255). 2. Reload the remaining processors. For example: > RELOAD (01 - 15), PRIME 3. Check that the reload initiated successfully. This message appears in the TACL window: PROCESSOR RELOAD: nn For more information about using the RELOAD command, refer to the TACL Reference Manual. Reloading Processors Using OSM The OSM Service Connection provides a Reload action on the Logical Processor object. You can perform the action on a single or multiple processors. The OSM action lets you reload an entire processor or omit a Blade Element from the reload action so you can dump the PE for that Blade Element before reintegrating it into the running processor. To reload a single processor, see Section 9, Processors and Components: Monitoring and Recovery. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -12 Starting and Stopping the System Reloading Processors To reload a multiple processors, use the Multi-Resource Actions dialog box (available from the Display menu of the OSM Service Connection): 1. In the Multi-Resource Actions dialog box, select Logical Processor from the Resource Types list. All Logical Processors in the system will be displayed in the right-hand pane. 2. Select Reload from the Action list under Selection Criteria. 3. From the list of Logical Processors, select all the processors and click Add to move them to the lower list (you can select and add one at a time, or Ctrl-click to select more than one). 4. Once all the processors you want to reload are in the lower list, click Perform Action. 5. Click OK to the dismiss the confirmation dialog box. 6. In the Logical Processor Reload Parameters dialog box (See Figure 15-2 on page 15-13), select the appropriate options. See OSM online help for information about the options. 7. Click OK. 8. Check that the reload initiated successfully. From the Low-Level Link, the Processor Status dialog box shows the status for the processor as “Executing NonStop OS.” Figure 15-2. Logical Processor Reload Parameters HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -13 Starting and Stopping the System Minimizing the Frequency of Planned Outages Minimizing the Frequency of Planned Outages To minimize the frequency of planned outages: • • Anticipate and plan for change Perform changes online Anticipating and Planning for Change Anticipating and planning for change is a key requirement for maintaining an enterprise-level, 24 x 7 operation. To avoid taking a NonStop NS-series system down unnecessarily: • • • Evaluate system performance and growth—Track system usage and anticipate system capacity and performance requirements as new applications are introduced. Provide adequate computer room resources—Avoid unnecessary downtime by ensuring you have enough physical space and power and cooling capacity to handle future growth. Configure the system with change in mind—Configure the system in a way that easily accommodates future growth. One way to do this is to select limits that allow for growth. For example, by configuring enough objects to provide for the anticipated growth of your online transaction processing environment, you can increase the maximum number of objects controlled by PATHMON objects without a system shutdown. Stopping Application, Devices, and Processes Whenever possible, schedule system shutdowns in advance so that system users are prepared. Then, stop applications, devices, and processes in an orderly fashion. To include shutdown commands in a shutdown file, see Stopping the System on page 15-16. Unless you stop a system in a careful and systematic manner, you can introduce abnormalities in the system state. Such abnormalities can affect disk file directories and can cause the processors to hang in an endless loop when you attempt to load your system. You must be aware of which processes must not or cannot be stopped. For example, some TCP processes must not be stopped. System processes must not be stopped. Generic processes configured to be persistent cannot be stopped. Note the effect on the system when you stop these applications: • Stopping Pathway applications begins shutdown of all TCP objects (shutting down TERM objects and then themselves) in parallel. New work is disallowed. The PATHMON process logs the start and completion of SHUTDOWN2. It does not log status messages during shutdown. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -14 Starting and Stopping the System • Stopping Application, Devices, and Processes Stopping DSM/SCM stops the CNFGINFO server process, the Pathway environment for DSM/SCM, the alternate EMS collector $ZPHI, and TCP/IP processes for DSM/SCM, as this example shows: STOP CNFGINFO server process $ZPHC STOP DSM/SCM Pathway system $YPHI PATHCOM $YPHI;SHUTDOWN !,WAIT $Z02H: TCP TCP-H, STOPPED $Z02H: TCP TCP-T, STOPPED STOP DSM/SCM Alternate EMS Collector $ZPHI • • Following the SPOOLER DRAIN command, the collectors allow current jobs to finish but reject new opens with a file-system error 66 (device downed). When you drain the spooler, each collector stops when it has no more open jobs. Each print process finishes printing any active jobs and then stops. After all collectors and print processes have stopped, the supervisor stops. The spooler enters the dormant state, ready to be warm started. Following the SCF CONTROL, DISK REFRESH command, all other disk I/O is suspended. The amount of time a refresh operation takes to finish depends on the amount of disk cache containing dirty pages in use at the time, and writing to disk can take several minutes. Stop processes and applications in this order: 1. After you send a message alerting users of the shutdown, stop all user applications. 2. If your system is equipped with Pathway, stop Pathway applications. At the Pathway prompt: = SHUTDOWN2, MODE ORDERLY 3. Stop Distributed Systems Management/Software Configuration Manager (DSM/SCM) if it is running. At a TACL prompt: a. Type this VOLUME command: > VOLUME $DSMSCM.ZDSMSCM b. Stop DSM/SCM: > RUN STOPSCM 4. Stop communications lines, such as Expand lines. 5. Identify and stop any remaining processes that should be stopped individually: a. Use the TACL PPD and STATUS commands to help you identify running processes. b. Use the TACL STOP command to stop running processes. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -15 Starting and Stopping the System Stopping the System 6. Drain the spooler. The SPOOLCOM SPOOLER DRAIN command stops the spooler in an orderly manner. It is the only recommended way to stop the spooler. At a TACL prompt: > SPOOLCOM supervisor-name, SPOOLER, DRAIN 7. Stop the TMF subsystem. At the TACL prompt: > TMFCOM STOP TMF 8. Refresh the disks to put them in an orderly state before shutdown. Use the SCF CONTROL DISK, REFRESH command: > SCF CONTROL DISK $*,REFRESH 9. If the system is a member of a ServerNet cluster, HP recommends that you first remove the system from the cluster. To remove the system from the cluster, refer to the ServerNet Cluster 6780 Operations Guide (for 6780 switches) or the ServerNet Cluster Manual (for 6770 switches). Stopping the System Stopping a system halts each processor (terminating all processes running in each processor) on the system in an orderly fashion. Alerts Before stopping a system: • • Stop applications, devices, and processes in an orderly fashion. See Stopping the System on page 15-16. To maximize application availability, make stopping the system a planned event whenever possible. Halting All Processors Using OSM To place processors in a halt state and set the status and registers of the processors to an initial state: 1. Prepare the system by shutting down applications and performing all tasks in Stopping the System on page 15-16. 2. Log on to the OSM Low-Level Link. 3. On the toolbar, click Processor Status. 4. In the Processor Status dialog box, select all processors to be halted. To select multiple processors, use the Shift key, but the processors must be in numerical order. For example, you can select processors 2, 3, and 4, but not 2 and 4. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -16 Starting and Stopping the System Powering Off a System 5. From the Processors Actions menu, select Halt. 6. Click Perform action. 7. A message box asks whether you are sure you want to perform a halt on the selected processors. Click OK. Powering Off a System Use OMS or SCF to place most system components in a low-power state before you remove power to all system components. Any attached I/O enclosures power off completely. The Disk Drive enclosures are not placed in a low power state after the power off action or command. To power off a system: 1. Stop applications. See Stopping Application, Devices, and Processes on page 15-14. 2. Use either of these methods to place most system components in a low-power state: ° ° System Power-Off Using OSM on page 15-17 System Power-Off Using SCF on page 15-17 3. Shut off AC power to all peripheral devices. 4. Locate the circuit breaker that controls the power cords. 5. Switch the breakers off. System Power-Off Using OSM 1. Log on to the OSM Service Connection. 2. Right-click the System object. 3. Select actions. 4. From the drop-down menu, select System Power Off. System Power-Off Using SCF To power off the system using SCF, log on to an available TACL command interpreter as the super ID (255,255) and issue the SCF power-off command: > SCF CONTROL SUBSYS $ZZKRN, SHUTDOWN HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -17 Starting and Stopping the System Emergency Power-Off Procedure Emergency Power-Off Procedure If possible, HP recommends that the system be in a low power state before you remove power to the system. However, in emergency situations, you might need to quickly remove AC power from a system. Sites equipped with an emergency power-off (EPO) switch can use it to remove AC power from your entire system. For more information on the EPO system, see the NonStop NS-Series Planning Guide. For sites that are not equipped with an EPO switch, switch off the circuit breakers to the power cords connected to the cabinets and peripherals. For more information, refer to Section 14, Power Failures: Preparation and Recovery. Troubleshooting and Recovery Operations Refer to the appropriate subsection for recovery information: • • • • • Recovering From a System Load Failure on page 15-20 Getting a Corrupt System Configuration File Analyzed on page 15-21 Recovering From a Reload Failure on page 15-21 Exiting the OSM Low-Level Link on page 15-22 Opening Startup Event Stream and Startup TACL Windows on page 15-22 If any of these problems occur when you power on a system, see the appropriate subsection for recovery information: • • • • • Fans Are Not Turning on page 15-18 System Does Not Appear to Be Powered On on page 15-19 Green LED Is Not Lit After POSTs Finish on page 15-19 Amber LED on a Component Remains Lit After the POST Finishes on page 15-19 Components Fail When Testing the Power on page 15-19 Fans Are Not Turning If the fans do not start turning a few seconds after you power on the server, check that the AC power cords and component power cords are properly connected. If the green LED lights are lit, but the fans are not turning, you must power off the system immediately. See in Powering Off a System on page 15-17. Contact your service provider. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -18 Starting and Stopping the System System Does Not Appear to Be Powered On System Does Not Appear to Be Powered On If AC power is being supplied to the server and the fans are turning but the server still does not appear to be powered, the server might be running internal tests. Wait several minutes (at least 10 minutes for large configurations). If the server is still not powered on after this time and you cannot determine the cause of the problem: • • Check your site’s circuit breakers. Plug in another device into the PDU that powers the LSU to check the power for that PDU. Green LED Is Not Lit After POSTs Finish It can take several minutes for the green LEDs on all system components to light: 1. Wait for the POSTs to finish. It might take as long as 10 minutes for all system components. 2. If the green LEDs still do not light: a. Check that AC power cords and component power cords are properly connected. b. If one green LED still does not light, a system component might have failed its POST. 3. If you cannot determine the cause of the problem, contact your service provider. Amber LED on a Component Remains Lit After the POST Finishes A fault might have been detected, or the component might not have been successfully initialized and configured. Contact your service provider. Components Fail When Testing the Power If a component fails when testing the power, the possible causes are listed in descending order of probability: • The component is plugged in improperly. Check the connection between each component power cord and PDU, and check the AC power receptacle to which the server power cord is connected. If necessary, unplug and plug each cord in again to ensure that it is seated properly. • • • • A power cord is defective. A component power supply is defective. A fuse is defective. The UPS, if installed, is not fully charged. HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -19 Starting and Stopping the System Recovering From a System Load Failure Recovering From a System Load Failure If a system load is not successful or if the system halts: 1. Check for messages in the System Load dialog box of the OSM Low-Level Link. 2. Check the Processor Status dialog box of the OSM Low-Level Link for halt codes. Look up the halt codes in the Processor Halt Codes Manual for further information about the cause of failure and the appropriate recovery procedure. 3. Check the startup event message window for any event messages. Record the event messages, and refer to the appropriate documentation for recovery information. Refer to the Operator Messages Manual for further information about the cause, effect, and recovery procedure for an event. 4. Check that the disk you selected to load from is in the specified location. 5. Check that the disk is properly configured as a system disk. 6. Correct the problems, and try loading the system again. If you cannot correct the problem, contact your service provider. 7. If you continue to have problems, load the system from each disk path for both the primary and mirror $SYSTEM drives. 8. If you cannot load the system using the current configuration file, load the system using a saved version of the system configuration file. See Configuration File on page 15-8. 9. If you still cannot load the system or if a CONFxxyy is not available, load the system from an alternate system disk if one is available. 10. If you cannot load the system from an alternate system disk, contact your service provider. You might be able to load the system from the CONFBASE configuration file and restore a previously backed-up configuration file. If you use this option, many additional steps are required to restore your system to normal working order. a. Load the system as described in Starting a System on page 15-5. In the Configuration File box, select Base (CONBASE) as the configuration file. b. Reload the remaining processors. See Reloading Processors on page 15-12. c. From the Startup TACL window, configure a tape drive. d. Restore a previously backed-up configuration file. e. Load the system as described in Starting a System on page 15-5 from the current configuration file (CONFIG). Check that the CIIN file is enabled. 11. After you load a system from a saved version (CONFxxyy) of the system configuration database file or the CONFBASE, verify that no pending changes to system attributes appear. From a TACL prompt: INFO SUBSYS $ZZKRN HP Integrity NonStop NS-Series Operations Guide —529869-005 15 -20 Starting and Stopping the System Getting a Corrupt System Configuration File Analyzed Pending changes can appear (but are misleading) if the earlier configuration has different system name, number, or time attributes than the configuration you replaced. For example, if you load the \EAST system from the CONFBASE file (which specifies \NONAME as the system name), an INFO SUBSYS $ZZKRN command displays \EAST as the current system and \NONAME as a pending change. Enter an ALTER SUBSYS command to change the system name to \EAST and cause the pending change to disappear. It is not displayed when you enter INFO. Getting a Corrupt System Configuration File Analyzed If the current system configuration file is corrupt, send it to your service provider for an analysis: 1. Return to a saved, stable configuration file. See Configuration File on page 15-8. 2. After the system is up and stable, copy to a backup tape the corrupt CONFSAVE file. For example: > BACKUP $TAPE, $SYSTEM.ZSYSCONF.CONFSAVE, LISTALL You must backup the CONFSAVE file before you perform the next system load. Another system load operation overwrites the CONFSAVE file you want analyzed. 3. Submit the tape to your service provider for analysis, along with a copy of any SCF command file or SCF log file of the commands that were part of the process that created the corrupt configuration. Recovering From a Reload Failure If a reload is not successful: 1. Check the Processor Status dialog box of the OSM Low-Level Link for halt codes. Look up the halt codes in the Processor Halt Codes Manual for further information about the cause of failure and the appropriate recovery procedure. 2. Check the System Load dialog box of the OSM Service Connection for messages. 3. Check for any event messages. Look up event messages in the EMS logs ($0 and $ZLOG) and refer to the OSM Event Viewer or the Operator Messages Manual for further information about the cause, effect, and recovery for any event message. 4. Perform a processor dump, if needed, as described in Dumping a Processor to Disk on page 9-15. 5. Try a soft reset of the processor. 6. Reload the processor or processors as described in Section 9, Processors and Components: Monitoring and Recovery. If you cannot to correct the problem, contact your service provider. 7. If you still cannot reload the processor or processors, try a hard reset of the processor.

Functions performed by MCS include configuring the Spooler, Pathway, and Expand lines, and creating startup and shutdown files. This section is about creating startup and shutdown files without the use of MCS. For more information about MCS, see the Integrity NonStop NS-Series Hardware Installation Manual. Startup You can use startup command files to automate the starting of devices and processes on the system, which minimizes the possibility of operator errors caused by forgotten or mistyped commands. The system is shipped with a basic startup file named CIIN, located on the $SYSTEM.SYS00 subvolume. The CIIN file must be specified in a particular way. See CIIN File on page 16-5 for more information. After the commands in the CIIN file are executed, other startup files can be invoked either automatically, from another startup file, or manually in commands entered by the operator. The startup file sequence usually starts the spooler and other system software first and then starts applications. HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 2 Shutdown Creating Startup and Shutdown Files Shutdown Automating system shutdown with a collection of shutdown files helps the operator bring the system to an orderly halt. The shutdown file sequence reverses the order of commands in the startup file sequence: applications are shut down first, followed by the spooler and other system software.

It is represented by the processes $YMIOP.#CLCI and $YMIOP.#CNSL, and the home terminal is represented by the $ZHOME process pair. $YMIOP.#CLCI $YMIOP.#CLCI is the primary interactive terminal for the operator interface to the system. This process: • • Runs on the system console Is preconfigured on your system during system generation TACL processes are started on $YMIOP.#CLCI by commands in the CIIN file. If a read operation is pending, such as a TACL prompt on $YMIOP.#CLCI, write operations are blocked, causing the process attempting the write operation to wait indefinitely. $YMIOP.#CNSL $YMIOP.#CNSL is a write-only device for logging. This process: • Runs on the system console HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 3 Creating Startup and Shutdown Files • $ZHOME Is preconfigured on your system during system generation $ZHOME The $ZHOME process is a process pair that provides a reliable home terminal to which processes can perform write operations. The $ZHOME process can be used by processes that must write to the system console but do not require a response. $ZHOME is preconfigured on your system by the CONFBASE file. $ZHOME is a generic process that is part of the SCF Kernel subsystem. Note the following about the configuration of $ZHOME: • • • The $ZHOME process is configured with $YMIOP.#CLCI as its HOMETERM, INFILE, and OUTFILE. Because $ZHOME acts as a reliable home terminal designed to interact with the system console, $YMIOP.#CLCI, HP recommends that you do not change its configuration. Most important: ° Do not specify $ZHOME for the INFILE, OUTFILE, or HOMETERM for the $ZHOME process. ° Never specify $ZHOME for the INFILE for a process. The $ZHOME process returns the FEINVALOP error (file-system error 2) in response to any read operation. Generic processes started by the $ZPM persistence manager inherit $YMIOP.#CLCI as the HOMETERM, INFILE, and OUTFILE unless these attributes are changed in the configuration record for the generic process. HP recommends that you configure most NonStop Kernel and system-level generic processes to use $ZHOME for the HOMETERM and OUTFILE. $ZHOME Alternative Instead of $ZHOME, you might want to use the optional NonStop Virtual Hometerm Subsystem (VHS) product if both of the following conditions are true: • • The processes you are configuring cannot handle error responses returned if $YMIOP.#CNSL or $YMIOP.#CLCI is not available. The process must perform read operations to the device. Example Command Files This section describes and shows examples of command files that can be used to start up and shut down the server: • Examples and sample programs are for illustration only and might not be suited for your particular purpose. HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 4 Creating Startup and Shutdown Files CIIN File HP does not warrant, guarantee, or make any representations regarding the use or the results of the use of any examples or sample programs in any documentation. You must verify the applicability of any example or sample program before placing the software into production use. • These examples are for a system whose configuration has been changed from the factory-installed configuration. Your system’s initial configuration will differ from these examples. The startup files in this section assume that the objects they start have already been added to the system configuration database. • • The IP addresses used in this section are examples only. If you use the example files described in this section on your system, you must change the IP addresses in these examples to IP addresses that are appropriate for your LAN environment. The configuration track-ID for the SWAN concentrator used in the example files, X001XX, is also an example. If you use the example files described in this section on your system, you must change the configuration track-ID used in these examples to the actual configuration track-ID assigned to your SWAN concentrator. CIIN File The CIIN file is a TACL command (OBEY) file that contains a limited set of commands that usually: • Start a TACL process pair on the system console for the system console TACL window ($YMIOP.#CLCI) When the startup TACL executes the commands in the CIIN file and terminates, the $YMIOP.#CLCI process pair lets you log on to the system and complete the system startup. Note. Before these TACL processes start, open the appropriate terminal emulator windows with the OSM Low-Level Link. You must open these windows before performing a system load. OSM software lets you define primary and backup IP addresses for TACL windows. For more information about configuring OSM software, see the OSM User’s Guide. • Load all processors that are not currently running Alternatively, the CIIN file can reload a minimal set of processors, such as processor 1, to bring up a minimal system. You can then test for successful startup of a minimal system environment before you bring up the remainder of the system. Normally, the initial TACL process invokes the CIIN file automatically after the first processor is loaded if all these conditions are true: HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 5 Creating Startup and Shutdown Files • • • Establishing a CIIN File The CONFTEXT configuration file located in the $SYSTEM.SYSnn subvolume has an INITIAL_COMMAND_FILE entry for the CIIN file. The CIIN file is available in the specified location. The CIIN option is not disabled in the System Load dialog box. Note. By default, the CIIN file contains commands needed to start the (permanent) TACL process pair and to reload all the processors in the system. Do not place commands to prime the processors in the CIIN file. Establishing a CIIN File The CIIN file is configured at the factory as $DSMSCM.SYS.CIIN. You do not need to establish this file. DSM/SCM automatically copies the CIIN file from the initial location into each SYSnn you create. Note. The CIIN file must be owned by a member of the super-group (255,n). HP recommends that you specify “N” for the read access portion of the file security attribute (RWEP) to allow the file to be read by any user on the network. For example, you might secure this file “NCCC.” The name of the CIIN file is specified in the INITIAL_COMMAND_FILE entry of the CONFTEXT configuration file. A system generation program (run from the DSM/SCM application) copies the file specified in the CONFTEXT file onto the SYSnn subvolume on the disk and renames the file CIIN. If no file is specified in CONFEXT, the operating system does not look for the startup file SYSnn.CIIN at system startup, even if you enable that file. You cannot simply copy a startup file to the SYSnn subvolume and name it CIIN. Modifying a CIIN File After the CIIN file is established on $SYSTEM.SYSnn (as part of running DSM/SCM), you can modify the contents of SYSnn.CIIN with a text editor such as TEDIT. You need not run DSM/SCM again to make these changes effective. HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 6 If a CIIN File Is Not Specified or Enabled in OSM Creating Startup and Shutdown Files If a CIIN File Is Not Specified or Enabled in OSM The results of the startup TACL process varies depending on whether a CIIN file is specified in the CONFTEXT file and whether the CIIN option is enabled. CONFTEXT CIIN Entry and CIIN File CIIN Option 1. CONFTEXT has CIIN entry, and file is available in specified location. Enabled CIIN is executed by initial (startup) TACL process. Upon completion, this TACL process terminates. You must log on to a different TACL process (the TACL process on $YMIOP.#CLCI started by the CIIN file) to complete the system startup process. 2. CONFTEXT has CIIN entry, and file is available in specified location, but file is empty or aborts because of syntax errors before another TACL process is started. Enabled CIIN is executed by initial (startup) TACL process. Upon completion, this TACL process terminates, leaving no TACL process available. You must reload the system with the CIIN option disabled in the System Startup dialog box invoked from the OSM Low-Level Link; then log on and correct the CIIN file. Then, either enable the CIIN option, using the System Startup dialog box, and reload; or complete the system startup process manually. 3. CONFTEXT has CIIN entry, but file is not available in specified location. Enabled Initial TACL process is started and left in logged-off state. You must log on to complete the system startup process. 4. CONFTEXT has CIIN entry. Disabled Initial TACL process is started and left in logged-off state. You must log on to complete the system startup process. 5. CONFTEXT has no CIIN entry. Enabled or disabled Initial TACL process is started and left logged on to the super ID (255,255). You must initiate the remainder of the system startup process manually and then log off. Results Caution. Situation 5 presents a security issue: the initial TACL process is left logged on to the super ID (255,255). You must either immediately continue with the system startup process (as described in the Results column), log on to another user ID, or log off.

Command files for startup or shutdown contain a series of commands that automatically execute when the file is executed. To automate and reduce the time required to start and stop your applications, devices, and processes: • • Include commands in one or more command files that you invoke from either a TACL prompt or another file. Write efficient startup and shutdown command files. ° ° ° Use command file syntax that executes quickly. ° Investigate and use product-specific techniques for fast startup and shutdown. Avoid manual intervention to ensure that command files execute quickly Use parallel processing to distribute startup and shutdown processes across multiple processors. Command File Syntax The syntax in command files affects the time it takes for them to execute. To ensure that your command files execute quickly: • Avoid using wild-card characters in command files A wild card is a character—typically an asterisk (*) or a question mark (?)—used to match any character or series of characters. When you use wild-card characters in your command files, execution time is increased because the system must look up names in a table. By using explicit names instead of wild-card characters, you shorten execution time and allow for commands to execute in parallel. This PATHCOM START command uses a wild-card character to start all of the TERM objects defined in the PATHMON configuration file: = START TERM * This PATHCOM START command uses explicit names to start all of the TERM objects defined in the PATHMON configuration file: = START TERM (TERM1, TERM2, TERM3, TERM4, TERM5, TERM6) Note. When using explicit names, you must revise your command files whenever a configuration change occurs. Therefore, you should balance the time it takes to update configuration files against the savings in startup or shutdown time. • Use single-line commands instead of multiple-line commands. Multiple-line commands in a command file increase execution time. HP Integrity NonStop NS-Series Operations Guide —529869-005 16- 9 Creating Startup and Shutdown Files Avoid Manual Intervention Avoid Manual Intervention Write startup and shutdown files so that they execute correctly without requiring manual intervention. Any time an operator must intervene, startup and shutdown time increase and the possibility of human error increases. Use Parallel Processing Parallel processing decreases the time required to start up or shut down your system or application because startup and shutdown processes are distributed throughout the processors in your system. For example, this SCF command file uses parallel processing in four processors to start several communications lines. The files START0, START1, START2, and START3 contain the actual commands that start the communications lines. This command file uses a special technique intended to ensure that each process gets started even if a given processor is out of service. The technique is to start each process in two processors. If the first processor is down, the command file continues to the next processor. If the first processor is up, and the process is started, the command file still continues to the next processor but fails because the process name ($Sn) is in use by the process that was successfully started. As a result, a specified process is started in whichever processor is running. Of course, if neither processor is up, the attempt to start the process fails.

If there are too many processes to start in processors 0 and 1, queuing and memory-contention problems can result. HP Integrity NonStop NS-Series Operations Guide —529869-005 16 -10 Creating Startup and Shutdown Files Investigate Product-Specific Techniques Investigate Product-Specific Techniques Some products provide commands that reduce the time required to start up or shut down their services. Familiarize yourself with the products and applications that run on your system to identify time-saving techniques for speeding startup and shutdown operations. Refer to the relevant documentation for each product. For example, the HP NonStop TS/MP product provides the COOL START option and the SHUTDOWN2 command to shorten startup and shutdown times, respectively. Using the COOL START option, rather than COLD START, to restart an existing transaction-processing system is much faster. The SHUTDOWN2 command is faster and more reliable than the SHUTDOWN command. Both of these techniques are described in the TS/MP System Management Manual. How Process Persistence Affects Configuration and Startup When the system is started, all processes that are configured to be persistent are started automatically by the persistence manager ($ZPM) or by the subsystem manager, which is started by $ZPM. For example, when the system is started, the WAN subsystem manager automatically starts all WAN I/O processes (IOPs) that were started before the system was shut down. However, communications lines and paths must be started manually by the operator. To make important system processes start automatically at system load and be persistent (that is, restart automatically if stopped abnormally), you should create them as generic processes in the system configuration database. See the Integrity NonStop NS-Series Hardware Installation Manual. For more information about persistence and the $ZPM persistence manager, see the SCF Reference Manual for the Kernel Subsystem. Tips for Startup Files HP recommends that you specify “N” for the read access portion of the file security attribute (RWEP) for your startup files to allow the files to be read by any user on the network. For example, you might secure these files “NCCC.” The sequence in which you invoke startup files can be important. Some processes require other processes to be running before they can be started. Be sure to indicate the order in which your startup files are to be run. Because the TCP/IP configurations are not stored in the configuration database, they are not preserved after system loads. Therefore, TCP/IP stacks must be configured as well as started each time the system is started. This is only true for conventional TCP/IP. HP Integrity NonStop NS-Series Operations Guide —529869-005 16 -11 Creating Startup and Shutdown Files Startup File Examples Startup File Examples You can implement the system startup sequence with a collection of startup files, each with a specific purpose. HP recommends that you invoke the startup files in this order: 1. Startup file for the system, to be invoked after the CIIN file is invoked 2. Startup files for the system software 3. Startup files for the subsystems 4. Startup files for the communications lines 5. Startup files for the applications See Section 15, Starting and Stopping the System for detailed instructions on the startup procedure. For information about automating disk processes upon startup, see the Integrity NonStop NS-Series Planning Guide. Note. Examples and sample programs are for illustration only and might not be suited for your particular purpose. HP does not warrant, guarantee, or make any representations regarding the use or the results of the use of any examples or sample programs in any documentation. You must verify the applicability of any example or sample program before placing the software into production use. For more information, see Example Command Files on page 16-4. System Startup File The following example shows a partial command file that starts up the system software and invokes other startup files. After the commands in the CIIN file have been executed and the initial system startup sequence is complete, the local operator invokes this file by entering the following TACL command: > OBEY $SYSTEM.STARTUP.STRTSYS Comment -- This is $SYSTEM.STARTUP.STRTSYS comment -- Start the server for labeled tape processing.

Monitoring Physical Facilities This subsection explains how to check the physical environment of your computer facility. You might be asked to monitor these aspects of your physical facility: • • • • Air temperature and humidity Physical security Order and cleanliness Fire-protection systems Checking Air Temperature and Humidity Check that the temperature and humidity are at the correct level established by management personnel. Monitor any sensors that control temperature and humidity. Your computer environment should have information posted that lists the names and telephone numbers of individuals that operators can call when a malfunction occurs with the heating, air conditioning, and humidity systems. HP Integrity NonStop NS-Series Operations Guide —529869-005 17- 1 Preventive Maintenance Checking Physical Security Checking Physical Security Your company’s security policy will guide you in the kind of security monitoring you perform. You might be asked to check doors and windows at the beginning and end of your shift and report the presence of unauthorized persons. In some facilities, operations staff might be responsible for monitoring and maintaining electronic security systems. Maintaining Order and Cleanliness Clutter and debris can cause accidents and fires. Dust, smoke, and spilled liquids can damage system hardware components. Depending on your company’s policies, you might be asked to keep the computer room clean; inspect air filters; keep printer dust under control through periodic vacuuming; and enforce a ban on smoking, eating, and drinking in the computer room. Checking Fire-Protection Systems You might also be asked to check the fire alarms and fire extinguisher systems in your facility. Cleaning System Components This subsection contains basic information about cleaning enclosures, printers, and tape drives. Many companies have service-level agreements with HP that include regular preventive maintenance (PM) of their hardware components. If a Field Service Organization (FSO) representative handles cleaning and other preventive maintenance for your company, you need not be concerned with the cleaning tasks mentioned here. Cleaning an Enclosure Cleaning an enclosure is an infrequent task that you perform as required by conditions at your site. Many installations require only occasional dusting. To dust an enclosure, use a lint-free, antistatic dust cloth. Caution. Do not use solvents or spray products on any part of an enclosure. If you need to clean an enclosure, use a cotton cloth and a cleaning product formulated for computer equipment. Or use a damp cotton cloth and a mild, nonabrasive soap. Cleaning and Maintaining Printers Inspect all printers and replace the ribbons on line printers as needed. Replace the toner cartridges of laser printers that are shared by the user community when print quality lessens. To remove paper dust that can affect printer operation, vacuum printers periodically. HP Integrity NonStop NS-Series Operations Guide —529869-005 17- 2 Preventive Maintenance Cleaning Tape Drives Cleaning Tape Drives Clean tape drive heads and sensors frequently. For detailed information on cleaning tape drives, refer to the documentation shipped with your tape drive. How often you clean a tape drive or the tape path depends on use, operating environment, and tape quality. Cleaning supplies are available from HP. Use these materials: • • • Cleaning solvent: HP supports the use of only isopropyl alcohol (91 percent or greater) as a tape-path cleaning solvent. Isopropyl alcohol cuts oil and grease, evaporates quickly, leaves no residue, and does not damage the tape path. Nonabrasive, lint-free cloths and swabs. A cleaning cartridge, which provides a safe, convenient way to clean some types of tape drives. For ordering information, see the operator’s guide shipped with the tape subsystem. Caution. These precautions are extremely important to prevent damage: • • • • • • Do not use cleaner solutions that contain lubricants. Lubricants deposit a film on the tape head and impair performance. Do not use aerosol cleaners, even if they contain isopropyl alcohol. The spray is difficult to control and often contains metallic particles that damage the tape head. Do not use soap and water on a tape path. Soap leaves a thick film, and water can damage electronic parts. Do not use facial tissues. Facial tissues leave highly abrasive lint on the tape path. Do not dip your cloths and swabs into the solvent can. These items contaminate the solvent. Discard the cloths and swabs after use. Even if they appear clean, cloths and swabs are contaminated by use. Dispose of these materials in an approved container. Handling and Storing Cartridge Tapes Cartridge tapes are nested in a cartridge by a spring-loaded mechanism that exposes the tape only when the cartridge tape is loaded into the tape drive. The drive mechanism uses a leader block to wind the tape through the tape path to load data. Exposing the tape or handling the cartridge tapes improperly can result in loss of data. When handling and storing cartridge tapes: • • • Protect cartridge tapes from shock or vibration. Do not expose cartridge tapes to high temperatures by leaving them in a car or in direct sunlight. Do not store cartridge tapes near magnetic fields such as those generated by power cables or computer monitors. HP Integrity NonStop NS-Series Operations Guide —529869-005 17- 3 Preventive Maintenance • • • Handling and Storing Cartridge Tapes Do not remove the leader block, pull out the tape, or press the reel lock. If the leader block is detached from the tape, contact the tape supplier for a leader block repair kit. When transporting cartridge tapes, do not stack the cartridges more than six high. Pack them carefully with the reel sides upright. The leader block edges can crack if they engage with each other. To store or transport tape cartridges in an ACL cartridge magazine, follow the same guidelines as you would for storing or transporting individual cartridge tapes. HP Integrity NonStop NS-Series Operations Guide —529869-005 17- 4 A Operational Differences Between Systems Running G-Series and H-Series RVUs Users familiar with systems running G-series RVUs will find several major differences in the operational environment of systems running H-series RVUs. Although many of the operations to be performed remain the same, the tools you use to execute these operations might differ significantly. For H-series RVUs, these changes have been made: • • • • • • • • • • • TSM is not supported in H-series. You must use OSM. Also, OSM’s graphical representation of modular systems has a different look in H-series. In power failures, there is no memory hold-up for H-series. Ride-through is available only if the customer has a site uninterruptible power supply (UPS) or an in-cabinet UPS for all the affected cabinets. TAPEBOOT is not supported in H-series. In H-series, native compilers and linkers have new names. Therefore, automated scripts might require changing. Subvol for public libraries is SYSnn in G-series. In H-series, it is ZDLLnnn and requires changing scripts. REPLACEBOOT only applies to TNS and TNS/R. It does not apply to TNS/E. On G-series servers, the OSS shell command ls displays the contents of directories without visually distinguishing between subdirectories and files. On Hseries servers, ls displays the contents of directories with a visual distinction between subdirectories and files -- subdirectory names are suffixed with a slash (/). This difference affects any OSS shell script that relied upon processing the output of the ls command. For H-series, DSM/SCM installation default is Manage OSS Files. For G-series, the default is not to manage OSS files. KMSF swap files have a larger memory size. It is now four times memory size per processor. Changes to automated debugging and dump mechanisms are required in H-series because of the new debuggers and debugger commands. The H-series OSS environment does not support TNS execution. OSS programs must be migrated to TNS/E native mode to run on an H-series system.

The use of some of these tools and utilities is discussed throughout this guide. For a list of other documentation that provides detailed information about these tools and utilities, refer to Appendix C, Related Reading. HP Integrity NonStop NS-Series Operations Guide —529869-005 B- 1 Tools and Utilities for Operations BACKCOPY BACKCOPY Use the BACKCOPY utility to create one or two duplicate tapes for archive storage, distribution, or disaster recovery. You can also create one or two labeled (or unlabeled) tape sets from a labeled or unlabeled tape set. The BACKCOPY utility duplicates tapes that are made from a BACKUP utility file-mode operation, but it cannot duplicate tapes that are made from a BACKUP utility volume-mode operation. BACKUP Use the BACKUP utility to copy files from disk to magnetic tape. Disk Compression Program (DCOM) The Disk Compression Program (DCOM) moves disk-file extents to yield more usable space on a disk. Use the DCOM utility to analyze the current space allocation on a disk, relocate file extents on a disk, and reduce the number of free-space extents. You can also combine free space into larger extents so that files can be allocated with larger extents, which decreases the incidence of file-system error 43 (unable to obtain disk space for file extent). Disk Space Analysis Program (DSAP) The Disk Space Analysis Program (DSAP) analyzes how disk space is used on a specified volume. The DSAP utility copies the disk directory and free-space table to the current work file. By specifying options, you can manipulate this data to produce several different reports about the use of the disk space for that volume. The freespace table is limited only by your primary (main) and secondary (contiguous disk space) memory requirements. EMSDIST The EMSDIST program is the object program for a printing, forwarding, or consumer distributor, any of which you can start with a TACL RUN command. Event Management Service Analyzer (EMSA) Use the Event Management Service Analyzer (EMSA) to extract specific types of event messages from EMS log files and to create an Enscribe database that you can query to analyze problem trends. HP Integrity NonStop NS-Series Operations Guide —529869-005 B- 2 Tools and Utilities for Operations File Utility Program (FUP) File Utility Program (FUP) The File Utility Program (FUP) is a component of the standard software package for the NonStop Kernel operating system. FUP software is designed to help you manage disk files, nondisk devices (printers, terminals, and tape drives), and processes (running programs) on the Integrity NonStop system. You can use FUP to create, display, and duplicate files; load data into files; alter file characteristics; and purge files. Measure Use the Measure program to collect and display system performance statistics about processors, processes, communication and network lines, files, disks, and terminals. Operations management personnel often use Measure to help fine-tune and balance a system. MEDIACOM MEDIACOM is the operator interface to the Distributed Systems Management/Tape Catalog (DSM/TC). It allows you to perform routine tape and tape-drive management operations. NonStop NET/MASTER NonStop NET/MASTER is used to integrate system and network management services. It serves as an alternative to the ViewPoint console application. NSKCOM and the Kernel-Managed Swap Facility (KMSF) NSKCOM is the command interface to the Kernel-Managed Swap Facility (KMSF). NSKCOM allows you to configure and manage permanently allocated swap files. OSM Package The HP Open System Management (OSM) product is the system management tool for Integrity NonStop systems. OSM offers a browser-based interface that improves scalability and performance and overcomes other limitations that existed in TSM. The OSM Low-Level Link has a new System Load dialog specifically for Integrity NonStop servers. TSM does not supported Integrity NonStop NS-series servers; OSM is required. For more information on the OSM package, including a description of the individual applications and how they differ from their TSM counterparts, see the OSM Migration and Configuration Guide and the OSM Service Connection User's Guide. HP Integrity NonStop NS-Series Operations Guide —529869-005 B- 3 Tools and Utilities for Operations PATHCOM PATHCOM PATHCOM is the interactive interface to the PATHMON process, through which users enter commands to configure and manage Pathway applications. PEEK Use the PEEK program to gather statistical information about processor activity, system storage pools, paging activity, message information, send instructions, and interrupt conditions. RESTORE Use the RESTORE utility to copy files from magnetic tape to disk. SPOOLCOM SPOOLCOM allows you to perform these tasks related to printing: • • • • Display the status of collectors, devices, print jobs, print processes, routing structures, and the spooler itself Change the location, state, or any attribute of your job Delete your print job from the spooler subsystem Restart a device that has gone offline with a device error Subsystem Control Facility (SCF) SCF configures and manages several subsystems that control system processes and hardware, including communications paths, disks, tapes, terminals, printers, and communications lines. You can run SCF from any workstation or terminal on the system after you are logged on. Use SCF to: • • • • • • • • Configure and add an object Remove an object Begin or restore access to an object Stop access to an object Show static configuration information for an object Show dynamic information for an object Automate subsystem startup and shutdown procedures Power off the system HP Integrity NonStop NS-Series Operations Guide —529869-005 B- 4 Tools and Utilities for Operations HP Tandem Advanced Command Language (TACL) HP Tandem Advanced Command Language (TACL) The TACL product is the command interface to the NonStop Kernel operating system. In addition to providing full command-interpreter facilities, you can program the TACL interface to help you manage your system in these ways: • • • Automate subsystem startup and shutdown procedures. For example, you can use TACL statements to initialize Pathway, the TMF subsystem, the TRANSFER system, and other subsystems. Run utilities and issue commands with either a fixed set of commands or a flexible set that you can tailor at run time. Create a customized environment that simplifies commonly performed tasks for users. TMFCOM TMFCOM allows you to enter commands that initiate communication with TMF, request various TMF operations, and terminate communication with TMF. Web ViewPoint Use Web ViewPoint, a browser-based product, to access the Event Viewer, Object Manager, and Performance Monitor subsystems. Web ViewPoint monitors and displays EMS events; identifies and lists all supported subsystems; manages NonStop server subsystems and user applications in a secure, automated, and customizable way; monitors and graphs performance attributes and trends; investigates and displays most active system processes; and offers simple navigation and a point-and-click command interface. ViewPoint Use ViewPoint to display event messages about current or past events occurring anywhere in the network on a set of block-mode events screens. The messages can be errors, failures, warnings, and requests for operator actions. The events screens allow operators to monitor significant occurrences or problems in the network as they occur. Critical events or events requiring immediate action are highlighted. HP Integrity NonStop NS-Series Operations Guide —529869-005 B- 5 Tools and Utilities for Operations ViewSys ViewSys ViewSys is a system resource monitor that displays processor performance statistics and resource consumption for a set polling period. It updates the numbers automatically at the end of each polling period, which allows you to evaluate the effects of changes as those changes are made. ViewSys indicates the current allocation of a given resource and the percentage of that resource used. Thus, possible resource contention problems can be detected before they become serious. Viewing the resource allocations across processors on a running system allows you to balance the application load more evenly. It can help you decide when to move user processes to processors and disk files that are less busy or when to relocate partitions to disk volumes that are less busy.

HP Integrity NonStop NS-Series Operations Guide —529869-005 D- 1 Overview of Numbering Systems Converting Numbers Overview of Numbering Systems Internally, a computer stores data as a series of off and on values represented symbolically by the binary digits, or bits, 0 and 1, respectively. Because numbers represented as strings of binary 0s and 1s are difficult to read, binary numbers are generally converted into octal, decimal, or hexadecimal form. Table D-1 describes the binary, octal, decimal, and hexadecimal number systems. Table D-1. Descriptions of Number Systems Number System Base Description Binary 2 Binary numbers are made up of the digits 0 and 1. Octal 8 Octal numbers are made up of the digits 0, 1, 2, 3, 4, 5, 6, and 7. Decimal 10 Decimal numbers are made up of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 Hexadecimal 16 Hexadecimal numbers are made up of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 and the letters A, B, C, D, E, and F. In manuals for the NonStop server, a percent sign precedes a number that is not in decimal form: • • • The % notation precedes an octal number. The %B notation precedes a binary number. The %H notation precedes a hexadecimal number. On some system displays, hexadecimal numbers are preceded by the notation 0X instead of %H.
