

If the LEDs are not all lit, you may have a failed hard drive. See "Software-RAID NAS System Hard-Drive Failures."



Software-RAID NAS System Hard-Drive Failures



Your software-RAID NAS system has a mirror of the operating system on hard drives, which allows you to recover in most cases. Depending on which drive

fails, use one of the procedures in Table6-1 to recover from a hard-drive failure.



Table 6-1. Software-RAID NAS System Hard-Drive Recovery Procedures



Software-RAID NAS System Software Failures



To recover from software failures when the main operating system files are missing or corrupt, manually boot from the recovery operating system mirror hard

drives 2 and 3. For instructions, see "Booting From the Software-RAID NAS System Recovery Operating System Mirror Hard Drives."



Replacing Software-RAID NAS System Hard Drives



This section provides the procedures for replacing hard drive 0, 1, 2, or 3, re-establishing the recovery operating system partitions, and booting from the

recovery operating system mirror hard drives.



Replacing Hard Drives

1. Remove the front bezel.

2. Remove the failed hard drive from the NAS system.



See your Installation and Troubleshooting Guide for information about removing and replacing drives.

3. If you are replacing hard drive 0 and the system is not powered on, move the hard drive in slot 1 to slot 0, and then insert the new hard drive into slot

1 and go to step5. Otherwise, proceed to step4.



This procedure allows the system to boot during step6.

4. Insert a new hard drive in the same location.

5. Replace the front bezel.

Hard Drive That Failed

Necessary Action

Replacing a single failed hard drive

Replace the failed hard drive. See "Replacing Software-RAID NAS System Hard Drives."

System."

6. Turn on the system, if it is not turned on already.



Recovering From a Software-RAID Operating System Failure



If the operating system fails, you can attempt to recover data by booting from the recovery mirror hard drives, and then reinstall the operating system using

the procedure in "Reinstalling the Operating System." This procedure requires that certain system files on the primary operating system volume (C:) are

accessible by the recovery operating system during boot and during the backup procedure. Ensure that all drives are installed prior to starting the recovery

procedure.



Booting From the Software-RAID NAS System Recovery Operating System Mirror Hard Drives



You might need the software-RAID NAS system to boot from the recovery operating system mirror so that you can perform a file restore on the main operating

system mirror or access the data on the data partition and back it up to tape.



To boot from the recovery drive, perform the following steps:

1. Shut down the NAS system.

2. Remove the front bezel.

3. Swap hard drives 0 and 2 with each other.



See your Installation and Troubleshooting Guide for information about swapping drives.

4. Swap hard drives 1 and 3 with each other.

5. Replace the bezel.

6. Turn on the NAS system.



The NAS system boots from the operating system on hard drives 0 and 1.



7. Log in to the NAS Manager.



See "Logging Into the NAS Manager" in "NAS Manager."

8. Back up your data and then reinstall the operating system.



See "Reinstalling the Operating System."



Hardware-RAID Recovery and Restoration Procedures



NOTE: The NAS system takes approximately 5 minutes to boot completely.

NOTE: The NAS system automatically starts rebuilding the operating system volume. The rebuild procedure may take several hours.

NOTE: If the volume does not start building, you do not have a drive that is the same size or larger than the failed drive, you did not have the

drive in the system when the system booted, or you were not using a RAID 1 volume. Use Array Manager to repair or reconfigure your volumes.

See "Disk and Volume Management."

NOTICE: The reinstallation procedure resets your NAS system to the Dell default settings and deletes all data on the NAS system. Before performing

this procedure, attempt to boot from the operating system image on the mirrored hard drives. See "Booting From the Software-RAID NAS System

Recovery Operating System Mirror Hard Drives." Booting from the recovery operating system mirror enables you to perform a file restore on the main

operating system mirror or access the data on the data partition and back it up to tape.

NOTE: The recovery operating system mirror is intended as a temporary way to back up data. After performing the backup, reinstall the operating

system using the procedures in "Reinstalling the Operating System."

NOTE: Because the system boots using the recovery image operating system with the Dell default settings, any configuration information is lost.

See "Configuring Your NAS System for the First Time" in "Initial Configuration."



This section provides instructions on how to recover the hardware-RAID NAS system if the operating system or a hard drive fails. Additionally, this section

provides information for possible solutions that do not require restoring the operating system or hard drives.



Because your NAS system is designed to have redundancy, it can recover from certain hardware and software failures. In some situations, it can recover

automatically, and in others, you must have administrator privileges and manually intervene to recover the NAS system.



Use the following methods in the order listed to restore your hardware-RAID NAS system:

1. Check all of the items in "Troubleshooting Hardware-RAID NAS Systems."

2. Check the procedures in "Hardware-RAID NAS System Hard-Drive Failures."



Troubleshooting Hardware-RAID NAS Systems



This section provides checks and solutions to try before you reinstall your operating system or replace a hard drive. Some of the checks require you to observe

the LEDs on the front and back of the NAS system. For more information about the LEDs, see your Installation and Troubleshooting Guide.

lDoes the power LED show that the NAS system is turned on?



Ensure that the power cable is connected to the NAS system and a power source and that the NAS system is turned on.

lAre the link LEDs on the back of the NAS system and any network switches to which it may be connected illuminated?



Ensure that the Ethernet cable is securely connected to the NAS system and a functioning Ethernet jack.

lAre you using a standard Ethernet cable to connect to the network?



Do not use a crossover cable.

lHave you allowed enough time for the NAS system to boot?



The NAS system typically takes several minutes to boot.

lDoes the NAS system boot completely?



Connect a keyboard, mouse, and monitor to the NAS system, and observe the boot process.

lAre the LEDs for all four hard drives on the NAS system lit?



If the LEDs are not all lit, you may have a failed hard drive. See "Hardware-RAID NAS System Hard-Drive Failures."



Hardware-RAID NAS System Hard-Drive Failures



Your hardware-RAID NAS system uses RAID 5 parity-redundancy functions to recover the operating system and data in most cases. Depending on how many

drives fail, use one of the procedures in Table6-2 to recover from a hard-drive failure.



Table 6-2. Hardware-RAID NAS System Hard-Drive Recovery Procedures

NOTICE: Do not use the following procedures to recover and restore a software-RAID or external- storage NAS system. If your NAS system uses

software RAID, see "Software-RAID Recovery and Restoration Procedures." If your NAS system uses an external storage configuration, see "External

Storage Configuration Recovery and Restoration Procedures." For instructions on how to determine the configuration of your NAS system, see

"Determining a NAS System's Configuration" in "NAS Manager."

Hard Drive That Failed

Necessary Action

Hard drive 0, 1, 2, or 3

Replace the failed hard drive. See "Replacing One Hardware-RAID NAS System Hard Drive."

Two or more hard drives fail

Replace the failed hard drives. See "Replacing Two or More Hardware-RAID NAS System Hard Drives."



Hardware-RAID NAS System Software Failures



Reinstalling the operating system on a hardware-RAID NAS system does not delete the data volume; therefore, a data recovery volume, which is available on

a software-RAID NAS system, is not necessary. RAID 5 redundancy protection is provided by its ability to recover data through parity matching. Therefore, if

the operating system files are missing or corrupt, the operating system must be reinstalled. See "Recovering From a Hardware-RAID Operating System

Failure."



Replacing Hardware-RAID NAS System Hard Drives



This section provides procedures for replacing hard drives 0, 1, 2, or 3. If a single hard-drive failed, see "Replacing One Hardware-RAID NAS System Hard

Issue

Possible Cause

Resolution

I just created a new volume on my

system but cannot see the volume on

Windows Explorer through Remote

Desktop.

Remote Desktop cannot update to

show a new volume during the session

in which it was created.

Log off Remote Desktop. When you reconnect to Remote Desktop, the

volume should be visible.

I see the following error message in

the event log:

WMI ADAP was unable to load the

winspool.drv performance library due

to an unknown problem within the

library: 0x0

This is an issue with the WDAP

Performance library and is documented

on Microsoft's website.

Connect to the system via Remote Desktop, and then open a local

command prompt. Type the following command: WINMGMT/CLEARADAP.

When the prompt returns, type WINMGMT/RESYNCPERF winmgmt service

PID.

I have just enabled FTP services on my

NAS system, but I am unable to upload

files using FTP even though I am the

administrator.

By default, no user has write

privileges on the default FTP site.

The FTP permissions must be configured using the Microsoft Management

Console (MMC). To access the MMC, log into Remote Desktop. Right click

My Appliance, and select Manage.Double-click internet Information

Services, and then right-click FTP Sites. Set the permissions in the FTP

Sites Properties window.

I have deleted an FTP share and folder

from my NAS system. However, when I

use Remote Desktop to confirm the

removal, I can still see the shared folder

in the FTP section of the MMC.

By default, this folder is not deleted by

the NAS Manager.

Manually remove this listing from the listed shared folders in the FTP

section of the MMC.

I cannot connect to or ping the NAS

system after turning it on.

The NAS system has not finished

booting.

Wait at least 5 minutes for the NAS system to finish booting.

If your NAS system uses software RAID and you still cannot connect,

attempt the procedures in "Troubleshooting Software-RAID NAS Systems"

in "Recovering and Restoring the System."

If your NAS system uses hardware RAID and you still cannot connect,

attempt the procedures in "Troubleshooting Hardware-RAID NAS

Systems" in "Recovering and Restoring the System."

I cannot connect to the NAS system

using the IPX protocol.

IPX networks require that you assign

an IPX network number to all clients.

By default, the NAS system does not

assign an IPX number to the network.

Change the IPX protocol on the NAS system to manually detect frame

types. See "Configuring the IPX Protocol" in "Advanced Features."

After restoring files from a backup, the

modified dates of folders are

inconsistent.

The modified dates of folders reflect

either the date you performed the

restore or the date the folder was

modified.

Do not take action. This design issue occurs only with folders; the files'

modified dates are consistent.

When connecting to my NAS system

using Remote Desktop, I receive a

message that the Terminal Server has

exceeded the maximum number of

allowed connections.

The NAS system supports only two

current Remote Desktop sessions at a

time.

Log off of the other Remote Desktop sessions.

The system summary and the task

manager show twice as many

processors as are actually installed in

the system.

The NAS system provides a

hyperthreading option, which allows

one physical processor to appear to

the operating system and other

applications as two logical processors.

Do not take action. Your NAS system is operating correctly.

The NIC LED on the front panel of the

NASsystemisnotlit.

A network connection problem exists.

Ensure that a network cable is properly connected to one of the NIC

connectors on the back panel of the NAS system. Do not use a crossover

cable. If the NIC LED is still not lit, see "Troubleshooting an Integrated

NIC" in your system Installation and Troubleshooting Guide.

The monitor screen is blank when

connected to the NAS system.

The video cable may not be connected

securely or the monitor may be faulty.

Inspect the video cable connection and ensure that the cable is

connected properly to the NAS system.

Try to connect to the NAS Manager using a client system. If the client

system is able to connect to the NAS Manager, replace the monitor.

All four hard-drive operation LEDs on

the NAS system are blinking green.

The green flash pattern indicates that

the RAID volumes are being rebuilt.

Wait at least 5 minutes, and then try to reconnect to the NAS system.



Table 10-2.NASManager

The NAS system may not be booting

properly.

You may not be allowing enough time

for the NAS system to boot or a system

alert may be occurring.

The NAS system requires at least 5 minutes to boot.

Connect a monitor to the NAS system or use console redirection to view

the boot routine of the system. If a system alert occurs (system message,

beep code, or amber hard-drive LEDs) during boot, see "Indicators,

Messages, and Codes" in the Installation and Troubleshooting Guide for

information on resolving the problem.

Power-on self test (POST) does not

occur when the system is turned on or

rebooted, but a beep code is heard.

A number of conditions can cause a

beep code during POST.

Write down the number of beeps, and see "Indicators, Messages, and

Codes" in the Installation and Troubleshooting Guide for information on

resolving the problem.

POST does not occur when the NAS

system is turned on or rebooted, and a

beep code does not occur.

The BIOS may need to be updated, or

a memory module or microprocessor

needs to be reseated or replaced.

Without disconnecting the power source, reboot the NAS system by

pressing <Ctrl><Alt><Delete>. You may need to repeat this key

combination several times. If the system now POSTs, upgrade the BIOS to

the latest version.

If the system still does not POST, try booting the system with each

individual memory module. See the Installation and Troubleshooting Guide

for more information. If the system does not boot with a certain memory

module installed, then that module is defective.

If the system does not POST with any of the memory modules, reseat the

processor as explained in the Installation and Troubleshooting Guide. If the

system does not boot, try replacing the processor with a working

processor. If the system does not boot, the system board may be

defective. See "Getting Help" in the system Installation and

Troubleshooting Guide.

I do not know the name of my NAS

system.

The name of the NAS system can be

viewed in My Network Places.

Double-click My Network Places on the desktop of the client system and

look for NAS system name. The default name for the NAS system is

DELLxxxxxxx, where xxxxxx is the system's service tag. For example, if the

service tag is 1234567, the system name is DELL1234567. You can find the

service tag on the top cover of the NAS system.

After using Remote Desktop to connect

to my NAS system, I am unable to type

using my native language.

The NAS system is set to English, the

default language.

Most character sets are installed by default on your system. If your

language character set is not installed, you can install your native

language character set from the Multilingual Support CD that was shipped

with your system. For installation instructions, see "Advanced Features."

The NAS system is attached to a DHCP

network, but I cannot connect to it

through the NAS Manager.

The DHCP server may have issued a

new DHCP address to the NAS system.

If the NAS system has been powered down for a period of time

predetermined by the DHCP server, the NAS system acquires a new DHCP

address from that server. The DHCP server may not have yet replicated

the new address with the NAS system name.

Wait approximately 15 minutes for the address to be replicated and then

try connecting again or try connecting to the NAS system again using the

IP address.

I cannot connect to the NAS system

using a static IP address.

You may be using the wrong address

syntax.

Ensure that you are correctly entering the address in the syntax

described in "Logging Into the NAS Manager" in "NAS Manager."

A NAS system has been moved to a

new network or new subnet and I

cannot connect.

The connection settings may need to

be refreshed.

If the NAS system is using DHCP, open a command line on the system

and use the ipconfig utility to release and renew the IP address.

If DHCP is not being used, verify that all NAS system network interface

settings are correct.

After reinstallation, a message displays

that says An error has occurred

during installation. Please see the

Windows Event Log for details.

Either an error occurred while

installing a component during the

reinstallation or the reinstallation was

interrupted.

See the Windows Application Event Log and the c:\dell\install\error.tag

file to determine which error occurred during the reinstallation, and then

reinstall your system again.

When you try to open the Shares page

using the NAS Manager, the page times

out.

Depending on the configuration of

your client system, the Shares page

may time out when the number of

shares exceed 20,000 shares.

Change the settings of your client system or manage large numbers of

shares through Remote Desktop.

Issue

Possible Cause

Resolution

I am trying to select the Administer

My Appliance link on the opening

page of the NAS Manager, but the

link does not function properly.

The user account that you used to log in to

the domain does not have administrator

privileges. The link does not work for users

without administrator privileges.

Type the address of the NAS Manager in your browser. For SSL

connections, type: https://servername:1279 or

https://IPaddress:1279

I have just deleted a volume, and

now I am unable to view my shares

in the NAS Manager.

If a volume with shares is deleted, then the

NAS Manager cannot display any shares until

the shares that were directed to the deleted

volume are removed.

Use Remote Desktop to remove the shares for the deleted volume. Exit

the NAS Manager, and restart the system. The shares should now be

visible.

I have just added an HTTP share

but cannot see it from the NAS

Manager.

For security purposes, directory browsing is

not enabled by default on an HTTP share

directed to the same folder or volume as

another share.

To enable directory sharing for an HTTP share, from the NAS Manager

Maintenance page, click Remote Desktop, and then modify the Web

sharing properties of the folder.

I have just changed the IP address

of my system, and now I cannot

administer it through the NAS

Manager.

Although the IP address changed, your local

host is still trying to communicate with the

system using the old IP address. It takes

approximately15minutesfortheIPaddress

to automatically update on most networks.

Close Microsoft Internet Explorer. Reconnect using the newly created

IP address. Type: https://IPaddress:1279. It takes approximately 15

minutes for the DNS server to recognize the new IP address.

I can only see the first 100 items in

the NAS Manager Web user

interface.

The NAS Manager will only display 100 items

per page.

To display the next 100 items, click the down-arrow icon at the top of

the list.

In the NAS Manager, if I click OK

and then click Cancel, it doesn't

Clicking Cancel does not dynamically stop

an update to the system after you click OK.

If an operation has been performed in error, the system administrator

must change the setting back manually.

When I select the Check All box

and then deselect one or more

choices on some screens in the NAS

Manager, the Check All box remains

selected.

The Check All box is not automatically

deselected. However, this does not mean

that all items in the list are selected.

This behavior does not affect functionality. The Check All box does not

indicate what has specifically been selected or deselected.

I have changed the password for

the administrator account; however,

several minutes have passed and I

have not been prompted for the

new password.

The NAS Manager does not automatically

refresh the account information for the

administrator while in the NAS Manager.

Instead, it performs the refresh as a timed

function.

The password was successfully changed. If you want to confirm that

the new password is in effect, close the browser, and then reconnect.

The new password should work, but the old one should not.

I am looking for a topic on the

context-sensitive online help in the

NAS Manager, but it says No Topic

Available.

Some sections of the NAS Manager do not

have context-sensitive help.

For information on a specific function, see the Windows Storage Server

2003 Help, which is available by logging into a Remote Desktop Session

and clicking the Start button and selecting Help and Support. You can

also see the appropriate section in this Administrator's Guide.

I tried to clear the FTP log or the

Web (HTTP) Shares log in the

Maintenance section of the NAS

Manager, but I received an error

message and the log was not

cleared.

The logs are currently locked by the NAS

system for the FTP service and to support

the NAS Manager. The logs cannot be

cleared in the NAS Manager.

Connect to the NAS system using Remote Desktop and clear these logs

by using Microsoft Management Console (MMC). You can access MMC by

logging into a Remote Desktop session and then right-clicking My

Appliance and selecting Manage.

While viewing the properties of a

user, I selected the General tab.

The fields for this user are now all

blank.

You were already on the General tab and

the page did not refresh properly.

Select Cancel or click Back on your browser. Reselect the user for

whom you want to view properties.

I added members to a local group

using the NAS Manager, but when I

click OK, the screen only refreshes.

You might have removed and then added

the same member to the local group. This

may cause the screen to refresh instead of

update correctly.

Reselect the Local Groups tab in the NAS Manager primary menu. Add

or remove the appropriate members to or from the local group.

I cannot change the WINS

addresses when I click Network on

the NAS Manager primary menu, click

Network Interfaces, and then click

WINS in the Tasks list.

The NAS Manager grays out the WINS

Servers Configuration page unless you set

the IP Address Configuration page to Use

the following IP settings.

To set the WINS addresses from the NAS Manager, click Network on

the primary menu, click Interfaces, and click IP in the Tasks list. On the

IP Address Configuration page, click the radio button for Use the

following IP settings, and then type the IP address, Subnet mask, and

the default gateway in the appropriate text boxes.

In the column for the percent used

on the Shadow Copies page, the

percentage of space used appears

to be inaccurate.

You need to verify the amount of space

being used by Shadow Copy.

To verify how much space Shadow Copy is using, select a volume, and

then select Properties. This page displays the amount of space used by

Shadow Copy on that volume.

Issue

Possible cause

Resolution

I cannot access the NAS Manager from

my Red Hat®Linux client system.

The NAS Manager is not supported by the Red Hat Linux

operating system and does not work with the NAS Manager.

Use a client system running Windows to connect to

the NAS Manager.

While updating client access to an NFS

share, the No Access option is

displayed, but the Root option is not.

Only the All Machines category options are displayed

during this update.

Add the appropriate client systems, and then

select OK. After you have added the client system,

navigate back to the NFS tab for this share and

select the correct options for the individual Client

Machines.

Every time I try to obtain a directory

listing from an NFS client on the root of a

system volume, I get an error message,

such as Permission Denied.

The problem you are experiencing involves a System

Volume Information directory created by Microsoft Index

Server. The NFS service does not have access to this

directory and returns an error message to the client when

trying to list its properties.

This issue only occurs when sharing the root of a drive

letter.

Ignore this error. The System Volume Information

directory is not used by NFS clients or your system

by default.

When updating the client system's

access to an NFS share, the All

Machines client group is reset from the

No Access access type to Read-Write

access.

The NAS Manager might reset the All Machines client

system's group to Read-Write when the client systems do

not have read-only or read-write access.

Add a client system that has read-write or read-

only access, and then set the All Machines client

system group to No Access.

My NAS system is experiencing low NFS

performance.

NFS write-back cache is disabled.

If your system is not part of a cluster, you can

enable NFS write-back cache to improve

performance. See "Advanced Features" for more

information.

The NFS client system group All

Machines is reset to No Access when

another client system group is set with

the same access permissions and root.

Setting a client group to use the same permissions as All

Machines causes All Machines to be reset to No Access.

Access the NAS system's desktop and modify the

NFS share properties of the folder directly.

I am getting inconsistent map

definitions when I use the NAS Manager

and the MMC to create user name maps.

Modifications to user name maps are cached and may not

take effect immediately.

Use only one tool to administer user name maps.

system using a keyboard, monitor, and mouse. 

Configuring Your NAS System for the First Time 

You can set the NAS system's basic configuration from another system on the network that has a keyboard, monitor, and mouse. This system is referred to as 
the client system. After you set the basic configuration, you can use the NAS Manager from any system on the network to set passwords, local users, shares, 
and so on. See "NAS Manager." 

You can configure your system for the first time in several ways, depending on whether Dynamic Host Configuration Protocol (DHCP) and Domain Name System 
(DNS) are installed on your network: 
lIf DHCP and DNS are implemented on your network, your system automatically configures the network settings. If you are unsure whether your 
network uses DHCP, contact your network administrator. See "Configuring Your NAS System Automatically on a Network (With DHCP/DNS)." 
 
lYou can use a keyboard, monitor, and mouse connected directly to the NAS system. See "Configuring Your System Using a Keyboard, Monitor, and

TheDell™PowerVault™NASManagerisaWeb-based user interface that is the primary tool for configuring NAS systems. This section provides basic

information on using the NAS Manager, including how to log on and navigate the interface, configuring network properties and IP addresses, creating users,

using shares and disk quotas, and managing disks and volumes.



Determining a NAS System's Configuration



Your NAS system is available from Dell in either a software-RAID, a hardware-RAID, or an external storage configuration. The following is an overview of the

types of NAS system configurations:

lIn a software-RAID hard-drive configuration NAS system, the RAID functionality is configured by the Microsoft®Windows®Storage Server 2003

operating system.

lIn a hardware-RAID hard-drive configuration NAS system, the hard drives are controlled by a Cost Effective RAID Controller (CERC)- Serial ATA (SATA)

card installed in a PCI expansion slot inside the NAS system.

lIn an external storage configuration, the internal hard drives are controlled by the operating system and the external hard drives are controlled by a

DellPowerEdge™ExpandableRAIDController(PERC)cardinaPCIexpansionslot.



The RAID hard-drive configuration of the NAS system affects some of the NAS Manager configuration procedures. Therefore, determine the RAID configuration

of your NAS system before continuing with other sections in this guide.



Use one of the following methods to determine the RAID configuration:

lCheck the RAID hard drive configuration on the NAS system System Version screen.

a. Log in to the NAS Manager.



See "Logging Into the NAS Manager."

b. Click Status.

c. Click System Version.



The System Version screen appears and the Disk Configuration row lists the system as either Hardware RAID, Software RAID, or External

Storage.

lIf the system has a CERC-SATA RAID controller card installed in a PCI expansion slot as explained in the Installation and Troubleshooting Guide, the NAS

system has hardware RAID. If the system has a PERC card in a PCI expansion slot, the system has external RAID storage. A software-RAID NAS system

does not have a RAID controller card installed.



NOTE: Although you can change RAID levels on your NAS system, you cannot change the basic configuration of your NAS system. For example, you

cannot change a system from a software RAID configuration to a hardware-RAID configuration.

NOTE: If the system has an external RAID connector, the RAID controller card is a PERC card.



Logging Into the NAS Manager



To use the NAS Manager, you must be logged in as an administrator. You can log in only if the NAS system is on the network or if you are connected directly to

the NAS system with a keyboard, monitor, and mouse.



Logging Into the NAS Manager on the Network



To connect to the NAS Manager using a secure SSL port, perform the following procedure:

1. Open a Web browser from a client system.



The NAS Manager supports client systems running Microsoft®Windows®operatingsystemsandInternetExplorer6.0orlater.

2. Type https://<system_name>:1279 (where <system_name> is the system's name and 1279 is the secure port) in the Address field in the Web

browser, and then press <Enter>.



The default system name is Dellxxxxxxx, where xxxxxxx is the system's service tag number. For example, if your service tag number is 1234567, enter

https://DELL1234567:1279.

3. When the Enter Network Password window displays, type a user name and password and then click OK to log in as the administrator.



You are now logged in to the NAS Manager.



Using Shares



A share is a folder on the NAS system that can be accessed on the network by systems running Windows, Novell®NetWare®, Macintosh, or UNIX®operating

systems.



A NAS system supports the following methods of sharing folders:

lDFS — Distributed File System (DFS) makes files that are distributed across multiple servers appear as if they reside in one place on the network.

lNFS — The Network File System protocol is used by client systems running UNIX.

lIPX — The Internet Packet Exchange protocol is used by client systems running NetWare. This protocol is not installed by default.

lFTP — The File Transfer Protocol is an alternative way of accessing a file share from any operating system. This protocol is disabled by default.

lHTTP — The Hyptertext Transfer Protocol is the protocol for accessing a file share from Web browsers.

lMicrosoft SMB — The Microsoft SMB protocol is used by clients running a Microsoft Windows operating system.

lAppleTalk — The AppleTalk protocol is used by clients running a Macintosh operating system. This protocol is disabled by default.



Adding a Share



This section does not contain information for creating NetWare shares. For information on creating NetWare shares, see "Sharing Netware Volumes" in

"Configuring Systems in a Heterogeneous Environment."



To create a share, you must supply a share name that is different from all other shares on the system. This is the name that the client system uses to access

the share. Some protocols also support the inclusion of a comment or brief description of the share. Additionally, you must enable at least one of the available

protocols.



NOTE: In a domain environment, do not create local users that have the same user name as domain users unless the local user and domain user

have identical passwords.

NOTE: In a domain environment, you cannot create domain groups through the NAS Manager. However, you can add domain users to your local groups.

NOTE: If you are adding a domain group, you must also enter the user name and password that will allow you to add from that domain.

NOTE: You must use the NAS Manager's Remote Desktop to administer NetWare shares. See "Advanced Features" for more information.



To add a share, perform the following steps:

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Shares.

4. In the Tasks list on the Shared Folders page, click New.

5. Type the share name and share path.

6. If you entered a nonexistent folder in the Share path, click Create folder.

7. Check the appropriate box(es) to specify the types of protocols to enable.



If you want to use a protocol that is grayed out, you must first enable it on the NAS system. See "Advanced Features" for information about enabling the

AppleTalk and FTP protocols.

8. If you want to provide access to the share as part of a Distributed File System (DFS) namespace, select Publish to DFS root: \\servername\root.



For more information about DFS and creating DFS roots, see "Using DFS."

9. Use the protocol tabs to configure the specific properties of each type of share.



See the context sensitive online help for more information on the properties for each protocol.

10. Click OK.



Modifying Share Properties

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Shares.

4. In the Shared Folders table, click the share you want to modify.

5. Click Properties.



The Share Properties page is displayed. Use this page to change the properties of the share, such as the protocols it supports.

6. Click OK.



Removing a Share



When you remove a share, the share becomes inaccessible; however, the actual files remain on the NAS system.



To remove a share, perform the following steps:

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Shares.

4. In the Shared Folders table, click the share that you want to delete.

5. Click Delete.



NOTICE: It is recommended that you create your data shares on the data drives. Shares that are created on the operating system drive will be deleted

if you reinstall the operating system.

Removing a Protocol From the Share



Because a share may have more than one protocol assigned, it is possible to remove a protocol from a share without removing the remaining protocols.



To remove one or more specific protocols from a share, perform the following steps:

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Shares.

4. In the Shared Folders table, click the share for which you want to remove a protocol.

5. Click Properties.

6. Uncheck the protocol(s) to remove it from the share.

7. Click OK to confirm the protocol removal, or click Cancel to keep the protocol(s) for the share.



Publishing a Share in DFS



A DFS namespace provides users with a logical grouping of shared resources that is independent of the resources' locations. Users can access resources

without needing to know where the resources reside. In DFS, you can also move a shared folder without affecting users.



To publish a shared folder in DFS, perform the following steps:

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Shares.

4. In the Shared Folders table, click the share that you want to publish in DFS.

5. Click Publish in DFS.

6. In the Publish to DFS root box, type the name of a DFS root.

7. Click OK.



For more information on DFS, see "Using DFS."



Disk Quotas



Disk quotas track and control the use of disk space for volumes. You can configure the volumes on your NAS system to:

lPrevent further use of disk space on a volume by a user and log an event when a user exceeds a specified disk space limit.

lLog an event when a user exceeds a specified disk space warning level.



When you enable disk quotas, you can set both the disk quota limit and the disk quota warning level.

lThe disk quota limit specifies the amount of disk space a user is allocated within a specific volume.

lThe warning level specifies the point at which the event log displays that a user is nearing the quota limit within a specific volume.



Forexample,youcansetauser'sdiskquotalimitto50MBandthediskquotawarninglevelto45MBonavolume.Withthesesettings,theusercanstoreno

more than 50 MB on the volume. If the user stores more than 45 MB on the volume, you can set the disk quota system to log a system event to the event log.



In addition, you can specify a quota limit for users but allow the users to exceed that quota limit. When you enable quotas without limiting disk space, you can

track disk-space use on a per-user basis without denying users access to a volume when they exceed that limit. It is also possible to specify whether the

system logs an event when a user exceeds the quota warning level and quota limit.



Enabling, Disabling, or Setting Disk Quotas on a Volume

1. Log in to the NAS Manager.

2. Click Disks.

3. Click Volumes.

4. On the Volumes page, click the volume to manage.

7. Click the Limit volume usage to check box and enter the volume usage limit.

8. Click OK.



Adding Disk Quota Entries



The Quota Entries page allows you to add, delete, or configure disk quotas for any NAS system user.



When you enable disk quotas for an existing volume, volume usage is automatically tracked for new users from that point forward. However, existing volume

users have no disk quotas applied to them. You can apply disk quotas to existing volume users by adding new quota entries in the Quota Entries window.



To add a new quota entry, perform the following steps:

1. Log in to the NAS Manager.

2. Click Disks.



Shadow Copies



Shadow Copy service allows the creation of point-in-time copies of your NAS system's data volumes. Shadow Copy software can be configured using the NAS

Manager.



Introduction to Shadow Copies



A shadow copy is a point-in-time copy of a shared file or folder. If you change a file on the active file system after making a shadow copy, the shadow copy

contains the old version of the file. If an active file gets corrupted or deleted, you can restore the old version by copying the file from the latest shadow copy or

restoring a directory or file.



Difference File



The Shadow Copies service stores changed data in a difference file. A difference file resides on each volume of your system. You can use the NAS Manager to

change the amount of space that is dedicated to the difference file.



Shadow Copies Considerations



When using shadow copies, note the following:

lWhen the shadow copy difference file reaches the maximum number of shadow copies (64 copies per volume), the system deletes the oldest shadow

copy file.

lShadow copies are read-only. You cannot edit them.

lShadow copies are made of entire volumes. You cannot make shadow copies of individual files or folders.

lNFS clients can access shadow copy data as read-only files.

lIf you add a volume and you plan to defragment that volume, format the source volume where you intend to enable shadow copies with an allocation

unit size of 16 kilobytes (KB) or larger. If you do not format the shadow copies volume, defragmenting the volume can cause previous versions of files to

be deleted.



Storing Shadow Copies



The NAS system can store a maximum of 64 shadow copies per volume; however, if you exceed the maximum, the oldest copy is overwritten. This number of

copies allows you to schedule multiple shadow copies.



Configuring Volume Settings

1. Log in to the NAS Manager.

2. Click Disks.

3. Click Shadow Copies.

4. Select the volume that you want to configure.

5. Click Properties.

6. Set the maximum size for shadow copies by either selecting No limit or selecting Use limit and entering the amount of disk space that can be used for

shadow copies.

NOTE: Shadow copies can be accessed through SMB and NFS shares. Shadow copies cannot be accessed through HTTP, FTP, AppleTalk, or NetWare

shares.

NOTICE: Shadow copies are temporary backups of your data that typically reside on the same volume as your data. If the volume becomes damaged

and you lose your data, the shadow copy is also lost. Therefore, using shadow copies should not replace performing regular backups.

NOTE: If you use NTFS file system file compression on the source volume, you cannot use an allocation unit size larger than 4 KB. Defragmenting

the source volume causes the difference file, which contains all changed data, to grow. If the difference file grows beyond the allocated space, you

might lose previous versions of some files. Having a large NTFS file cluster size decreases the growth of the difference file.

7. Click OK.



Using Shadow Copies



In addition to scheduling shadow copies, you can make new copies on demand, delete existing copies, configure the shadow copies environment, and set

shadow copy retention weights.



6. In the Tasks list, click Properties.

7. Change the settings as desired.

8. Click OK to save the shadow copy settings.



Accessing Shadow Copies



The files and folders within a shadow copy are identical to the permissions on the original files and folders.



Accessing Shadow Copies From Client Systems Running Windows



Clients running Windows operating systems must meet the following requirements, depending on the operating system, to access shadow copies:

lClient systems running Windows Server 2003 already have the software available to access shadow copies.

lClient systems running Windows XP need to install the previous versions pack. This pack is located in the %systemroot%\system32\clients\twclient

directory of your NAS system.

l Client systems running Windows 2000 and Windows NT®need the Shadow Copy Client system software, which is available at microsoft.com.



When the client software is installed, perform the following steps to access shadow copies:

1. Map to a share on the NAS system with the folder file that you want to access

2. Right click the folder or file you want to access and click Properties.

3. Click the Previous Versions or Shadow Copies tab to display previous versions that you can access.

4. Click the desired previous version.

5. Click View to browse the folder.

6. Click Copy to copy the contents to a new location.

7. Click Restore to restore the contents to the original location (If it is a folder, all subdirectories will also be restored).



Accessing Shadow Copies From Client Systems Running UNIX



Client systems running UNIX®do not require additional software to access a shadow copy. When a client system mounts a share with shadow copies,

shadow copies are a pseudodirectory of the share in the format .@GMT-YYYY.MM.DD-HH:MM:SS.



You can browse shadow copy pseudodirectories like any other directory. Permission rules are the same as for client systems running Windows, except that

client systems running UNIX with permissions when the shadow copy was taken will have permissions to access the shadow copy.



Defragmenting a Volume Containing Shadow Copies



Defragmenting the source volume causes the difference file to increase. If the difference file increases beyond the allocated space, you might lose previous

versionsofsomefiles.Evenwitha16KBclustersize,theshadowcopydifferencefilewillincrease.Ifthedifferenceincreasestoomuch(greaterthanthe

maximum set), shadow copies will be deleted.



If you do not have to keep shadow copies, delete them before defragmenting to improve the performance of the defragmentation. See "Deleting a Shadow

Copy."

lHardware RAID — If your NAS system uses hardware RAID, see "Hardware-RAID NAS System Drive Configuration." 
 
lExternal Storage RAID — If your NAS system uses external storage RAID, see "External Storage NAS System Drive Configuration." 
 
 

Software-RAID NAS System Drive Configuration  

The NAS system in a software RAID configuration contains four SATA hard drives. Each drive contains both a copy of the operating system and one or more 
data partitions. See Table3-1 and Figure3-1. Working copies of the Microsoft Windows Storage Server 2003 operating system and boot sectors are installed 
on two hard drives that are in a RAID 1 mirrored configuration. An additional copy of the operating system is placed on the other two drives in RAID 1 
NOTE: For instructions on how to determine if you have a software-RAID or a hardware-RAID NAS system, see "Determining a NAS System's 
Configuration" in "NAS Manager." 

partitions. Data can be stored on all four SATA hard drives in partitions that are configured as RAID 5 by default.



Table 3-1. Software RAID Default Hard-Drive Partitions

Figure 3-1. Software RAID Default Hard-Drive Partitions



Each hard drive has front-panel LEDs that provide information about the drive and RAID volume(s). See "Front-Panel Indicators" in the Installation and

Troubleshooting Guide for the location of the LEDs. Table3-2 provides the front-panel RAID volume LED codes.



Table 3-2. Front-Panel RAID Volume LED Codes



Hardware-RAID NAS System Drive Configuration



A NAS system with hardware RAID configuration contains four SATA hard drives that are connected to a CERC SATA RAID controller. Unlike the software-RAID

NAS system where Windows Storage Server 2003 controls the hard drives, the drives in the hardware-RAID NAS system are controlled by a RAID controller

card installed in a PCI expansion slot. All four CERC-SATA hard drives appear as only two virtual disks to the operating system. See Table3-3 and Figure3-2.

The operating system and boot sectors are installed on one RAID 5 volume that is spanned across the four CERC-SATA hard drives. Data can be stored on the

other RAID 5 volume that is also spanned across the four CERC-SATA hard drives.

External Storage NAS System Drive Configuration



The NAS system in an external storage configuration uses software RAID with two internal SATA hard drives for its operating system. See Table3-5 and

Figure3-3. The working copies of the Windows Storage Server 2003 operating system and boot sectors are installed on the two hard drives in partitions that

are in a RAID 1 mirrored configuration. Data can be stored only on external storage drives attached to the system through a RAID controller.

Creating Virtual Disks



The first step in configuring your system for improved system management is creating virtual disks.



To create a virtual disk, perform the following steps:

1. Right-click an array group.

2. Click Create Virtual Disk to display the Create Virtual Disk Express Mode window.



3. Select the RAID level that you want to use for the virtual disk.

4. Type the name of the disk in Name and click Finish.



The virtual disk is displayed in the Array Manager console.



Deleting Virtual Disks



1. Right-click the virtual disk.

2. Click Delete.



A confirmation dialog box appears.

3. Click OK to continue.



The virtual disk disappears from the right pane.

4. Reboot your system after deleting a virtual disk and before creating new virtual disks.



Reconfiguring and Managing Virtual Disks



This section summarizes how you can change the virtual disk configuration through the NAS Manager.



Reconfiguring a Virtual Disk



Perform the following steps to add array disks to a virtual disk or to change the virtual disk's RAID level.



1. Right-click a virtual disk.

2. Click Reconfigure.



NOTE: Virtual disks created using a supported PERC controller card cannot be created from array disks with an aggregate size greater than 2 terabytes

(TB). This limitation is a standard SCSI limitation. For example, you cannot select more than 30 array disks that contain 73 gigabytes (GB), regardless of

the size of the resulting virtual disk. When you attempt to select more than 30 disks of this size, a message indicates that the 2-TB limit has been

reached and that you should select a smaller number of array disks.

NOTE: Using Express Mode to create a virtual disk selects the maximum number of disks for the selected RAID type. To manually select the

number of disks, use Advanced Mode.

NOTICE: Deleting a virtual disk permanently deletes all information contained on that disk.

NOTICE: You must delete all shares and shadow copies from your volume before deleting it. If a volume is removed before all shares of that volume

have been removed, the NAS Manager might not display the shares correctly.

NOTE: The PERC 4/DC controller does not detect a drive status change until you attempt to read from or write to the drive. For example, when an

unconfigured drive is removed, the controller does not detect the change until a you perform a manual rescan or read/write to the drive.

NOTE: The NAS system supports RAID 1 to RAID 0 and RAID 5 to RAID 0 migrations.



The Virtual Disk Reconfiguration dialog box appears. The available disks are listed in the left pane. You can choose appropriate disks to add by

selecting them and using Add Disk to move them to the right pane.

3. Select the RAID level in the Type drop-down menu.

4. Click OK to continue or Cancel to cancel the operation.

5. To view your progress, click the parent of the virtual disk.



The status of the virtual disk will be Reconstructing, and progress information displays until the Add Member operation is finished. At the end of the

operation, the Type category shows the changed RAID level.



Using Change Policy



To change the cache policies of a virtual disk, perform the following steps:

1. Right-click a virtual disk.

2. Click Change Policy.



The Virtual Disk Change Policy dialog box displays.

3. From the pull-down menu, choose the policies you want.



You can enable or disable the write-cache or enable or disable the read-cache.



4. Click OK to continue or Cancel to quit the operation.



When you are finished, click Properties to verify if the policy changes occurred.



Using Check Consistency



If your disk is in a degraded state, using Check Consistency might restore your disk to Ready status.



To check mirror synchronization and rebuild parity if necessary, perform the following steps:

1. Right-click the virtual disk to be checked.

2. Click Check Consistency.



The Check Consistency operation displays progress information in the right pane.

3. To view progress, click the parent of the virtual disk.



The status of the virtual disk is Resynching, and progress information displays until the operation is finished.



Properties



This command displays a window that shows the properties associated with the virtual disk.



NOTE: You cannot change the Write Cache settings on a Hardware-RAID virtual disk after the arrays have been created.

NOTE: The write-cache is enabled by default. Disabling write-cache may negatively impact your system's performance.

Blink Virtual Disk



This command allows you to locate the array disks included in a virtual disk by blinking the LEDs on the array disks. This command automatically cancels after a

shortdurationsuchas30or60seconds.



Unblink Virtual Disk



This command allows you to cancel the Blink Virtual Disk command before the 30- or 60-second time limit has been reached.



To disable the alarm sound, perform the following steps:

1. Right-click a controller.

2. Click Disable Alarm.



Rebuild Rate



The Rebuild Rate command changes the rebuild rate settings. The rebuild rate is the fraction of the compute cycles dedicated to rebuilding failed drives. A

rebuildrateof100percentmeansthesystemistotallydedicatedtorebuildingthefaileddrive.



During a rebuild, the complete contents of an array disk are reconstructed. A rebuild operation can occur during normal operation; however, it will degrade

performance. You can reduce the rebuild rate to maintain system performance during the rebuild operation; however, a reduced rebuild rate extends the

rebuild time.



NOTICE: The default rebuild rate is 30 percent. System performance might be degraded if you change the rebuild rate to a higher value than the

default.

Properties



The Properties command displays controller attributes.



1. Right-click the appropriate controller.

2. Click Properties.



A Controller Properties dialog box appears displaying Name, Vendor, Status, Type, Firmware Version, and Cache Size of the controller.



Enclosure Management



The PERC 4/DC and 4/SC controllers and Array Manager support storage enclosure management. Array Manager displays the properties of the enclosure's

fans, power supply, and temperature probes. Array Manager also notifies you of enclosure status changes through events that are displayed on the Events

tab and logged in the Windows Event Log.



Enclosure Components in the Tree View



When you expand a storage subsystem in the Array Manager tree view in the left pane, you see the controllers that are attached to the storage subsystem.

You can expand the controller to display the controller's channels. Expanding an enclosure channel displays the enclosure's fans, power supply, and

temperature probes. Each of these objects expands to display the individual fans, power supplies, and temperature probes within the enclosure.



Thermal Shutdown



Enclosure management provides a feature that automatically shuts down the operating system, the server, and the enclosure when the enclosure's

temperature reaches dangerous temperature extremes. The temperature when shutdown occurs is determined by the enclosure temperature probe's

Minimum Error Threshold and the Maximum Error Threshold. These thresholds are default settings that cannot be changed.



Enclosure Fans



The fans that are installed in the enclosure are displayed under Fans in the tree view in the left pane. You can select and expand Fans to display the individual

fans and their status information in the right pane. You can also expand Fans to display the individual fans in the left page.

warning threshold. See the Set Thresholds for Temperature command in "Enclosure Commands" for information on setting the warning threshold.



Right-clicking Temperature Probes in the left pane displays a context menu with a Properties option. You can also expand Temperature Probe to display the

individual temperature probes in the tree view. Right-clicking an individual temperature probe also displays a context menu with a Properties option. This

option enables you to set the minimum and maximum warning threshold for the selected temperature probe.



Enclosure Commands



This section describes the commands associated with the enclosure and its fans, power supplies, and temperature probes. For the commands associated with

the array disks in an enclosure, see "Disk Commands."



Right-clicking an enclosure object in the tree view displays a context menu with the enclosure commands. Right-clicking the enclosure's fans, power supplies,

and temperature probes also displays a context menu for each of these components.



The enclosure's context menu items can vary depending on the model of the enclosure. The enclosure context menu might include any of the following

commands:

lRescan — Checks whether any new array disks and other components such as fans or temperature probes have been added to the enclosure.

lEnable Alarm — Enables an audible alarm that sounds whenever the fault LED lights.

lDisable Alarm — Turns off the audible alarm settings. If the alarm is already sounding, you can turn it off with this command.

lSet Tag Data — Allows you to enter or change asset information for the enclosure.



lEnclosure Properties — Displays enclosure properties.

lSet Thresholds for Temperature — Sets the minimum and maximum values for the temperature warning threshold. This command is located on the

context menu for the individual temperature probes, not on the main context menu.



Disk Management



This section describes conceptual and procedural information about how to implement basic and dynamic disks using Array Manager.



Monitoring Disk Reliability



Array Manager supports Self-Monitoring Analysis and Reporting Technology (SMART) on array disks that are SMART enabled.



SMART performs predictive failure analysis on each hard drive and sends an alert if a hard disk failure is predicted. The RAID controllers check the array disks

for failure predictions. If the RAID controller predicts a failure, it passes the information to the Array Manager. Array Manager immediately displays an alert icon

for the hard drive, raises an alert under the Events tab, and puts an alert message in the Windows Storage Server 2003 Event Log.



Managing Volumes Using Disk Management



This section describes how to use the Windows Disk Management tool to manage basic and dynamic volumes.

NOTE: The Download Firmware command is only available on the PowerVault 220S and PowerVault 221S enclosures.

NOTE: The supported PERC controllers do not report SMART alerts for unassigned or hot-spare hard drives. Also, when you pause controller I/O, the

controller does not send SMART alerts or events.



Accessing the Disk Management Tool

1. Log in to the NAS Manager as an administrator.

2. Click the Disks tab.

3. Click Disks to manage disks.

4. When the Remote Desktop session launches, log in as an administrator.



5. When the Computer Management screen displays, click on Disk Management to manage disks.



Initializing a Disk



When you create a virtual disk and perform a rescan in a hardware-RAID or external storage configuration or when a new disk is discovered on a system with

a software-RAID configuration, the disk appears with a Disk Type of Unsigned Disk. The unsigned disk cannot be used until it is initialized.



To initialize a disk, right-click the unsigned disk. A menu displays showing the Initialize Disk command. (The Initialize Disk command appears only if a disk

does not have a signature on it.) Select this command to write a signature on the disk.



After a signature is written on a disk, the disk displays as a Basic Disk. You can create partitions on the basic disk, or you can upgrade the disk to dynamic to

create volumes on it.



Upgrading a Basic Disk to a Dynamic Disk



Because only dynamic disks can be used for online volume extension, it is recommended that you use the Disk Management tool to upgrade all data disks on

your system to dynamic. The upgrade includes new disks, which are added to the system as basic disks.



To upgrade a basic disk to a dynamic disk, perform the following steps:

1. Right-click the disk you want to upgrade, and then click Convert to Dynamic Disk.

2. When the Convert to Dynamic Diskwindowappears,selectthediskstoupgradeandclickOK.

3. When the Disks to Convert window appears, select the disks that you want to convert to dynamic and click Convert.



Reactivating Dynamic Disks



A dynamic disk might appear as a missing disk when it is corrupted, powered down, or disconnected. You can reactivate a dynamic disk to bring it back online

by performing the following steps:

1. Right-click the disk marked Missing or Offline dynamic disk.

2. Click Reactivate Disk on the menu.



Mark the disk as Online after the disk is reactivated.



NOTE: The NAS Manager default administrator user name is administrator and the default password is

powervault.

NOTICE: In hardware-RAID configurations, the operating system disk must remain a basic disk. However, you can upgrade all data disks to dynamic

during creation by using the Windows Disk Management tool.

NOTICE: In hardware-RAID configurations, the operating system disk must remain a basic disk.

NOTE: After a disk is upgraded to dynamic it cannot be reverted back to basic unless all volumes on that disk are removed. Dell strongly recommends

that you do not revert a disk back to basic after data volumes are present.

Merging Foreign Disks



Dynamic disks with a foreign status are disks that have been moved from another system. You cannot reactivate a foreign disk; you must merge the disk to

the system. To change the status of a foreign disk and enable it to be seen as a part of the current system, use the command Merge Foreign Disk.



Perform the following steps to merge foreign disks:

1. Right-click a foreign disk, and then click Import Foreign Disks.



The Import Foreign Disk Wizard is displayed.

2. Select the foreign disks that you would like to merge to the system.



By default all foreign disks are selected to be merged.

3. Click Next.

4. Click Next again to validate the volume status of each foreign disk.

5. Click Finish.



Volume Overview



A volume is a logical entity that consists of portions of one or more physical disks. A volume can be formatted with a file system and can be accessed by a drive

letter.



Like disks, volumes can be basic or dynamic. Basic volumes refer to all volumes that are not on dynamic disks. Dynamic volumes are logical volumes created

from dynamic disks.



It is recommended that you create all data volumes on dynamic disks. On a hardware-RAID system, only the operating system disk should remain basic.



Checking Partition or Volume Properties

1. Right-click the partition or volume to be checked.

2. Select Properties from the context menu.



The Properties window displays.

3. Check the properties for your volume.



Formatting a Partition or Volume

1. Right-click the volume or partition you want to format, and then click Format.

2. When a message warns that all data on the partition will be lost and asks if you want to format the disk, click Yes.

3. Select NTFS as the file system type.



4. Enter a label for the volume.



The label appears on the Array Manager console. If a name has been selected, this name appears in the Name field. You can change the name by typing

a different name.

5. Enter an allocation size or use the default, which is automatically selected.



NOTE: Your NAS system supports only NTFS partitions. Formatting all partitions as NTFS allows for advanced features only available under that file

system.

6. Select the file system type and formatting options:

lPerform a quick format — This option formats the volume or partition without scanning for bad sectors in the volume or partition. Check this box

to use this format method.



lEnable file and folder compression — This option can be used only if you selected NTFS format. Check this box to use this format method.

7. Click OK to begin formatting.



A progress bar displays in the list view.



Deleting a Partition or Volume



1. Right-click the designated volume, and then click Delete Volume.

2. Click Yes to delete or No to cancel.



The volume is removed immediately if you click Yes.



Working With Dynamic Volumes



Dynamic volumes are volumes created on dynamic disks using the Disk Management tool. This section discusses how to create and extend dynamic volumes.



Creating a Dynamic Volume



1. Access the Disk Management tool.



See "Accessing the Disk Management Tool."

2. In the bottom half of the window, right click on the basic disk that you want to make dynamic and click Convert to Dynamic Disk.

3. In the Convert to Dynamic Disk window, click to select the disk(s) that you want to convert and then click OK.

4. When the Disks to Convert window appears, click Convert.



Extending a Dynamic Simple or Spanned Volume



You can extend a volume only if the following are true:

lThe volume is formatted as NTFS.

lThe volume was originally created on a dynamic disk.

lUnallocated space exists on a dynamic disk onto which the volume will be extended.



NOTE: If you use NTFS file system file compression on the source volume, you cannot use an allocation unit size larger than 4 KB. Defragmenting a

source volume with shadow copies causes the difference file, which contains all changed data, to grow. If the difference file grows beyond the

allocated space, you might lose previous versions of some files. Having a large NTFS file cluster size decreases the growth of the difference file.

NOTE: To decrease the time it takes to format your disk, use the Quick Format option.

NOTICE: You must delete all shares and shadow copies from your volume before deleting it. If a volume is removed before all shares of that volume

have been removed, the NAS Manager might not display shares correctly.

NOTICE: It is recommended to format the source volume where you want to enable Shadow Copies with an allocation unit size of 16 KB or larger if you

plan to defragment the volume. If you do not create this allocation, previous versions of files may be deleted. If you require NTFS compression on the

source volume, however, you cannot create an allocation larger than 4 KB. If you defragment a volume that is very fragmented, you may lose older

versions of files.

NOTE: The maximum supported volume size is 2 TB.

You cannot extend a volume if any of the following are true:

lThe volume is formatted as FAT or FAT32.

lThe volume is using software RAID (striped, mirrored, or RAID 5 volume).

lUnallocated space is not available on a dynamic disk.



You can extend simple and spanned volumes on dynamic disks onto a maximum of 32 dynamic disks. However, after a volume is extended, it cannot be

mirrored or striped using software RAID. Also, no portion of a spanned volume can be deleted without deleting the entire spanned volume.

1. Right-click the simple or spanned volume you want to extend, and then click Extend Volume.



The selected volume appears in the dialog box along with its current size.

2. Enter the amount to extend the volume, and then click OK.

3. Click OK.



The volume now shows the size of the extended volume.



For more information about extending volumes, see the context-sensitive online help.



Enabling and Disabling Hard Disk Write Cache on Software RAID NAS Systems.

1. Log in to the NAS Manager.

2. Click Maintenance→ Remote Desktop, and log in to your NAS system



3. On the system desktop, right click on My Appliance and select Manage.

4. From the Computer Management MMC, select Device Manager from the left frame.

5. In the right panel, expand Disk Drives by clicking +.



A list of the hard drives attached to the integrated SATA controller is displayed.

6. Right click the hard drive for which you wish to enable or disable write cache, and click Properties.

7. On Disk Device Properties, click the Policies tab.

8. Enable or disable write cache on the hard drive by checking or unchecking the box next to Enable Write Caching on Disk.



9. If enabling write cache, select Enable Advanced Performance.



This option causes application requests to bypass disk write caching to be ignored.

10. Click OK to apply changes.



Back to Contents Page



NOTE: The NAS Manager default administrator user name is administrator and the default password is

powervault.

NOTICE: Enabling write cache, which causes data to be cached by the drive before it is written to disk, may lead to data loss if the system loses power.

To prevent data loss, Dell recommends using a UPS with your system if write cache is enabled.



NFS Write Cache



NFS write cache is enabled on Windows Storage Server 2003 Standard Edition.



User Name Mapping



User Name Mapping provides mapping of names between the UNIX®and Windows environments. You can configure User Name Mapping from the MMC

Console or by using the NAS Manager to configure properties for the NFS Sharing Protocol. With User Name Mapping, you can create simple maps between

Windows user accounts and corresponding UNIX accounts. You can also use the Advanced Map feature to map accounts with dissimilar names. Because UNIX

user names are case-sensitive, and Windows operating system names are not, the use of User Name Mapping can greatly simplify maintaining and managing

accounts in the two environments. User Name Mapping uses Network Information Service (NIS) or local Personal Computer Network File System (PCNFS) user

and group files to authenticate users. Also, User Name Mapping supports bidirectional one-to-many mapping, allowing you to map a single UNIX or Windows

operating system account to multiple accounts in the other environment. For example, you can map more than one administrative account in a Windows

operating system to the UNIX root account.



Special Mappings



By default, the root user for the UNIX client is mapped to an unmapped user. This setting is commonly known as "root squashing." When an NFS

authentication request is made for a user name mapped to an unmapped user, the result is an anonymous user ID (UID) and group ID (GID). These IDs are

typically -2 and -1, respectively. Any files created by such a user will show file ownership as an anonymous Windows user.



NOTE: The default administrator user name is administrator and the default password is

powervault.



Configuring User and Group Mappings



To provide security for server files accessed from a UNIX environment, Server for NFS requires the system administrator to map UNIX user and group accounts

to Windows accounts either on the server or in a Windows Domain. Users then have equivalent access rights under UNIX as they have under Microsoft

Windows. Alternatively, Web sites with less stringent security needs can bypass the mapping procedure and treat all UNIX users as anonymous users.



User and Group Mapping lets you create maps between Windows and UNIX user and group accounts even though the user and group names in both

environments may not be identical. You can use simple maps, which map Windows and UNIX accounts with identical names. You can also create advanced

maps to associate Windows and UNIX accounts with different names. You can also use a combination of simple and advanced maps. With User and Group

Mappings, you can obtain UNIX user and group information from one or more NIS servers or from imported passwd and group files.



To create user and group name maps, perform the following steps:

1. Log in to the NAS Manager.

2. From the NAS Manager, click Shares.

3. Click Sharing Protocols.

4. Click NFS Protocol, and then click Properties.

5. Click User and Group Mappings.

6. Use the User and Group Mappings window to define your user and group maps.



To configure the type of server to be used to access UNIX user and group names, perform the following steps:

1. On the User and Group Mappings window, click General.

2. Click Use NIS server, or click Use password and group files to select the server type.

3. Depending on whether you use an NIS server or password and group files, perform one of the following steps:

lFor password and group files, specify the location and filename of the UNIX password file and UNIX group file.



lFor NIS server, type the NIS domain and, optionally, the name of the NIS server.

4. Click OK to apply the configuration.



Simple Maps



If enabled, simple maps create automatic mappings between UNIX users and Microsoft Windows users that share the same user name. In a simple user map,

users in a Windows domain are implicitly mapped one-to-one to UNIX users on the basis of user name. When the Windows domain and the UNIX passwd and

group files or NIS domain are identified, the simple-maps function maps users who have the same name in the Windows and UNIX or NIS domain. If no match

exists for a user name in either place, that user is not mapped.



To define simple maps, perform the following steps:

1. In the User and Group Mappings window, click Simple Mapping.

2. Click Enable Simple Mapping.

3. On the Windows domain list, select the server name, or the domain to which the server belongs.



If you select the server name, only the local users and groups will be mapped.

4. Click OK to create the maps.



NOTE: To prevent root squashing for specific NFS shares, the UNIX root user and group must be mapped to the Windows administrator user and group.

The access type for the NFS share's permissions must also be set to root for each applicable client or client group.

NOTE: Only a user's primary GID is used by Server for NFS for user/group name mapping. Secondary GIDs are ignored. When adding a new user

mapping, always create an associated group mapping for that user's primary GID. Users whose primary GIDs are not also mapped will be associated

with the anonymous group.

NOTE: The UNIX password file and group file formats must conform to the UNIX standard for these files.

Explicit User Maps



User and group mapping also allows an administrator to create cross-platform maps among Microsoft Windows and UNIX users and groups, even when the

user and group names in both environments are not identical. These maps are called explicit mappings.



User and group mapping allows you set up one-to-one or one-to-many mappings among Windows and UNIX users and groups. For example, a Windows user

name could be mapped to a UNIX user name, or a group of Windows users could be mapped to a single UNIX user account. You can also map a group of UNIX

users to a single Windows user account; however, this can present problems that are detailed in the online help for Services for UNIX. Explicit user maps can

also be used when the same person has different user names on Windows and UNIX accounts.



If you are defining explicit maps, you create user and group maps individually. To create explicit maps, perform the following steps:

1. On the User and Group Mappings window, click Explicit User Mapping to create user maps, or click Explicit Group Mapping to create group maps.

2. Specify the Windows Domain. If the server is configured as PCNFS, go to step 4.

3. Click List UNIX Users or List UNIX Groups button to populate the UNIX Users or Unix Group box.

4. Create map entries by selecting a Windows user or group and a UID or GID from the list and clicking Add.

5. Click OK to create the maps.



To delete explicit user maps, perform the following steps:

1. In the User and Group Mappings window menu, select the user or group mapping you want to delete from the Explicitly mapped users or group list

2. Click Remove.

3. Click OK.



Managing NFS Share Access



Access is granted or denied to each NFS share based on the client computer accessing the share. Client access can be granted based on an individual

computer or a client group. A client group contains one or more client host names.



To create an NFS client group, perform the following steps:

1. Log into the NAS Manager.

2. Click Shares, and click Sharing Protocols.

3. Select NFS, and then click Properties.

4. Click Client Groups.

5. In the Tasks list, click New.

6. On the Create New NFS Client Group page, type the group name you want to add in the Group name box.

7. In the Client name or IP address box, type the system name or IP address you want to add to the group.

8. Click Add.

9. Click OK.



To add a client or client group to an NFS share, perform the following steps:

1. Log into the NAS Manager.

2. Click Shares.

3. On the Shares page, Click Shares.

4. Select the share for which you want to add an NFS client or client group.



For information on how to create a share, see "Using Shares" in "NAS Manager."

5. In the Tasks list, click Properties.

NOTE: Only a user's primary GID is used by Server for NFS for user/group name mapping. Secondary GIDs are ignored. When adding a new user

mapping, always create an associated group mapping for that user's primary GID. Users whose primary GIDs are not also mapped will be associated

with the anonymous group.

6. Click the UNIX Sharing tab.

7. Select the machine or group from the list on the left, or type an NFS client computer name or IP address in the box on the right.

8. Select the degree of control the specified client can exercise over files in the share from the Access Permissions list.

9. Select the Allow root access check box to grant root access to the selected group.

10. Click Add.

11. Click OK.



To remove a client or client group from an NFS share, perform the following steps:

1. On the Shares page, click Shares.

2. Select the share for which you want to remove an NFS client or client group.

3. In the Tasks list, click Properties.

4. Click the UNIX Sharing tab.

5. Select the system or client group from the list in the center of the page, and then click Remove.

6. Click OK.



Basic Scenarios



For UNIX and Windows NT®user name mapping, an NIS Server must already exist in the UNIX environment, or UNIX user and group files must exist on the

NAS system. User name mapping associates UNIX users and groups to Windows NT users and groups. You can use two types of maps, simple and explicit.

Simple maps define a one-to-one relationship between the same user names and groups. Explicit maps define a relationship between dissimilar user names

and groups.



Workgroup



In the workgroup scenario, you configure user name mapping locally on the NAS system. All maps are contained on this system, and Windows NT pass-through

authentication is performed locally on the NAS system.



Domain



In the domain scenario, you configure user name mapping locally on the NAS system. All maps are contained on this system, but Windows NT pass-through

authentication for domain users is performed by the domain controllers. This scenario requires that the Services for NFS Authentication component of Microsoft

Services for UNIX 3.0 is installed on all domain controllers.



Filename Character Translation



Although Windows and UNIX file systems do not allow certain characters in filenames, the characters that are prohibited by each operating system are not the

same. For example, a valid Windows filename can not contain a colon (:), but a UNIX filename can. If a UNIX user attempts to create a file in an NFS share and

that file contains an illegal character for Windows in its name, the attempt will fail.



You can use filename character translation to replace characters that are not allowed in a file system by mapping them to characters that are valid. To enable

filename character translation, create a text file that maps Windows to UNIX characters, and then modify the registry entry that specifies the path and name of

the translation file.



The filename character translation text file is a list of mapped characters in a format such as the following:



0xnn : 0xnn [ ; comment ]



where nn is the hexadecimal value of the character

NOTE: SFU 3.0 is an optional component that you must purchase separately from Dell.



The entry for a map from the UNIX character ":" to the Windows character "-" in the filename character translation text is as follows:



0x3a : 0x2d ; Map ':' (0x3a) to '-' (0x2d)



To map the character combination "()" to the character "^", add the following entry:



0x28 0x29 : 0x5e ; Map '()' to '^'



To set up the character translation, perform the following steps:

1. Log in to the NAS Manager.

2. From the NAS Manager, click Maintenance.

3. Click Remote Desktop.

4. Log on as an administrator.



5. Double-click the NAS Utilities icon on the desktop of the NAS system.

6. Double-click Administrative Tools.

7. Double-click Microsoft Services for Network File Systems.

8. Click Server for NFS.

9.  On the right pane, click Server Settings.

10.  Set the desired filename character translation.



Services for Macintosh



Services for Macintosh (SFM) provides the tools needed to integrate Macintosh and Windows networks by leveraging existing Macintosh network resource and

expertise. SFM is disabled by default on the NAS system. See "Enabling the AppleTalk Protocol" for information about enabling SFM.



Enabling the AppleTalk Protocol



The AppleTalk protocol is disabled on the NAS system by default. You must enable the AppleTalk protocol for Macintosh clients to access the NAS system.

4. Click AppleTalk Protocol, and then click Properties.

5. In the AppleTalk Service Properties window, type the log on message that will be displayed when the user logs on, click the Security check box if you

allow workstations to save passwords and select the type of authentication to be used, and specify the number of concurrent sessions that are

allowed.

6. Click OK to complete the configuration.



Adapter Bindings



SFM can bind to only one network adapter. By default, it is bound to the embedded 10/100 network adapter. To change the binding in systems with multiple

network adapters, the AppleTalk protocol properties for the network adapter to be used by AppleTalk must be modified to accept inbound connections.



AppleTalk Protocol Adapter Binding



To modify the AppleTalk protocol adapter binding for systems with multiple network adapters, perform the following steps from the NAS Manager:

1. Log in to the NAS Manager.

2. Click Network.

3. Click Interfaces.

4. Click the radio button next to an enabled adapter to bind the AppleTalk protocol.



5. On the Tasks menu, click AppleTalk.

6. Click the check box next to Enable inbound AppleTalk connections on this adapter.

7. Optionally, if you use AppleTalk zones, select the appropriate zone in the drop-down box.

8. Click OK.



Microsoft UAM Volume



A user authentication module (UAM) is a software program that prompts users for an account name and password before they log in to a server. The

Macintosh Chooser has a standard UAM built in that uses the clear-text password or Apple's RandNum Exchange method of security.



Microsoft Authentication offers an additional level of security because the password is used as a key to encrypt a random number. If the system administrator

has determined that encryption is an important security measure, you may be asked to use Microsoft Authentication in addition to Microsoft UAM

authentication.



Viewing Netware System Properties



To view Netware system properties on Windows Storage Server 2003, perform the following steps:

1. From a Remote Desktop session, click Start, point to Programs→ Administrative Tools, and click Server Manager.

2. In Server Manager, click the FPNW menu, and then click Properties



Configuring the NWLink IPX/SPX Compatible Protocol



To configure this protocol, you need the internal network number, frame type, and network number.



Internal Network Number



Internal network numbers are used for internal routing and are generally needed only for servers. You should not need to change this option on your system.



Frame Type and Network Number



Frame types define the packet formats that are used by different networks. All systems in a network must have the same frame type so that they can

communicate with the rest of the network.



When you are configuring your system, it attempts to automatically detect the frame type for the client. In most cases, this is successful. However, the

automatic detection feature occasionally selects an inappropriate frame type, usually because more than one frame type exists on the network. If this

happens, you should manually set the frame type to match the one specified on the server running NetWare.



NOTE: SFN is not installed by default.

NOTE: The specified volume must have been created earlier.

NOTE: You cannot use the NAS Manager to manage NetWare shares.

NOTE: If more than one frame type exists, select the one that is detected first. For example, if the frame types Ethernet 802.2 and Ethernet 802.3 are

boundtothesamesegment,configureframetypeEthernet802.2.TheorderofdetectionisEthernet802.2,Ethernet802.3,EthernetII,andthen



Configuring the IPX Protocol



By default, the Internet Packet Exchange (IPX) protocol is configured on the NAS system to automatically detect frame types. To use the IPX protocol, you must

change your NAS system's IPX properties to manually detect frame types.



To configure IPX to manually detect frame types, perform the following steps:

1. Log in to the NAS Manager.

2. Click Maintenance, and then click Remote Desktop.

3. Log in to the NAS system as an administrator.



4. Right-click Network Places on the NAS system's desktop, and then click Properties.

5. In the Network Connections window, right-click the network adapter used by the NAS system and select Properties.

6. In the Local Area Connection Properties window, click NWLink/IPX/NetBIOS Compatible Transport Protocol, and click Properties.

7. In the NWLink/IPX/NetBIOS Compatible Transport Protocol window, select Manual Frame type detection.

8. Click Add.

9. In the Manual Frame Detection window, select a frame type, enter a network number for the IPX network, and then click OK.

10. Click OK.

11. Click OK to close the Local Area Connection window.

12. Close the Network and Dial-Up Connections window.



The IPX protocol is now configured on the NAS system to manually detect frame types.



Microsoft Directory Synchronization Services



Microsoft Directory Synchronization Services (MSDSS) allows you to synchronize a wide variety of data stored in the Active Directory service with Novell

Directory Service (NDS) and NetWare 3.x binderies.



MSDSS is a highly flexible service that helps Novell users to perform the following tasks:

lAdopt Windows 2000 Server and the Active Directory service

lReduce directory management through two-way synchronization

lMigrate NDS and bindery information to Windows 2000 Server



MSDSS supports two-way synchronization with NDS and one-way synchronization with NetWare 3.x binderies to provide a complete directory interoperability

solution. MSDSS also supports password synchronization and provides a directory migration service.



MSDSS allows NetWare users to deploy Active Directory without having to replace existing directories or bear the cost of managing two separate directories.

As a result, users have the flexibility to:

lConsolidate directory management when multiple directories are required

lManage accounts from either directory

lUse directory-enabled applications, devices, and services based on the Windows 2000 Active Directory service



MSDSS is easy to use and makes synchronization and Active Directory setup easy through its management interface. It is fully featured to allow users a choice

of management, synchronization, and migration options.



Ethernet SNAP.

NOTE: The default administrative user name is administrator and the default password is powervault.

MSDSS supports all major NetWare platforms and most Novell directories and binderies, and it includes support for IPX/SPX and TCP/IP network protocols.



Windows Server 2003 MSDSS Domain Controller



To implement MSDSS, you must install the Windows Server 2003 operating system and the MSDSS software (available on the Microsoft Services for NetWare

Version 5 or later CD) on at least one system. In Windows Server 2003, when you promote a system running Windows Server 2003 to an Active Directory

server, it becomes a domain controller. You use this domain controller to configure Active Directory, install MSDSS, and then import information from the

existing NetWare environment.



The larger the environment, the more new servers you need. If you are planning to have more than one domain, then you need new hardware for the first

domain controller in each domain.



You must also install Novell Client Access software on the MSDSS server or servers. MSDSS uses Novell Client Access to authenticate and to access NDS. While

accessing NDS, it authenticates, but does not use a license. MSDSS also uses Novell Client Access to map one directory's contents to another, taking into

account the fact that the object classes in Novell's NDS or bindery directories are different from Active Directory object classes. Novell Client Access is also

required to use the File Migration utility to migrate files.



You can install Novell Client Access in four modes: IP only, IPX only, IP and IPX combined, and IP with IPX Compatibility. Most NetWare environments still

use IPX. MSDSS works in all the modes because it uses Novell Client Access to access the lower layers.



If you are migrating NDS, you can import the user and group information from one NDS server to the MSDSS server because you have one user database per

tree. You can then migrate the file system. Remember that each Novell server has its own file system, which is not replicated to other servers (whereas NDS is

replicated to other servers). After the files are migrated, you can uninstall NDS from the server to provide more space for the Windows Server 2003 operating

system.



Outline of the MSDSS Deployment Procedure



The next two sections describe the procedures for implementing MSDSS in a smaller (local area network [LAN] only) or larger (wide area network [WAN])

network. You should adapt the guidelines to suit your environment and goals.



Small Environment



A small company with a LAN-based, simple network is often a likely candidate for a quick migration. After doing all the preparations described in the previous

section, perform the following steps (adjusted, if necessary, to your situation):

1. Back up your NetWare system and user data.

2. Install and configure a Windows domain controller (see the documentation that came with your operating system software).

3. Install the Novell Client for Windows from the Novell website at www.novell.com/download.

4. Replace services or applications that require NDS with software that is compatible with Active Directory. (Remove NDS applications before you begin

using MSDSS, except for ZENworks, which can be replaced by IntelliMirror at any time.)

5. Install MSDSS from the system DomainUtils share.



6. Log in to the NDS tree or bindery server as administrator.

7. Log in to the appropriate Windows domain as a member of the Domain Admins group.

8. On the MSDSS server, open the Help files, and then print out the procedures "To perform a one-time migration" and "To migrate files."

9. Click the Start button, and then point to Programs→ Administrative Tools→ Directory Synchronization to start MSDSS.

10. Follow the instructions as described in the help topic "To perform a one-time migration." The prompts guide you through the following steps:

a. Right-click MSDSS in the console tree, and then click New Session to start the New Session Wizard.

b. Specify whether objects are to be copied from NDS or Bindery.

c. Click Migration.

d. If you plan to migrate files as well as directory objects, click the Migrate Files check box.



NOTE: To access MSDSS software, map a network drive to \\Dell

xxxxxxx

\DomainUtils, where xxxxxxx is the system's service tag number. For

example, if your service tag number is 1234567, type http://DELL1234567.

You must also run the File Migration utility.

e. Specify the path to the Active Directory container in which you want to copy items.

f. Accept the default domain controller in which to store the migration log.

g. Specify the NDS Container or Bindery Container from which to copy items.

h. Provide the name and password of the Novell administrative account.

i. On the Initial Reverse Synchronization page, specify the password options (such as Set passwords to the user name.)



When you are performing a migration, this page does not include the option to actually perform an initial reverse synchronization, but it is the

page where you specify which password option you want to use.

j. Set Synchronization mode to Default object mapping or to Custom object mapping.

k. If you selected Custom object mapping, you are prompted to manually establish one-to- one relationships between pairs of objects.

l. Click Finish.



11. After the user accounts are migrated, you can migrate the file system (migrating the users before the files allows you to migrate file-system

permissions). Follow the instructions in the help topic "To migrate files." The prompts guide you through the following steps:

lTo start the File Migration Utility, click the Start button and point to Programs→ Administrative Tools→ File Migration Utility.



To view mapping relationships, click View Maps.

lTo view mapped access rights for the users, groups, organization units, and organizations to be migrated, click Access Rights.



The NDS Modify option converts, by default, to Read because it does not have an equivalent NFTS right. You might want to click the Write check

box to allow read/write access.

lOn the Step 2 — Security Accounts tab, verify that you are logged on with the correct Active Directory, NDS, or Bindery credentials.

lOn the Step 3 — Source and Target tab under Source (NDS/Bindery), click the volume or directories from which you want to migrate files.

Under Target (Active Directory), click the shares or directories to which you want to migrate files, click the Map button, and then click Next.



If the NDS or Bindery volume you selected in the source tree displays Unavailable, you are not currently logged in to that tree or Bindery server.

lOn the Step 4 — Log File tab, select your logging options, and then click Next.

lOn the Step 5 — Scan tab, click Scan, and then click Next.



The utility scans all source volumes and counts and displays the number of directories and files in each. It ensures that proper access has been

given to each source volume, directory, and file. If any errors occur, the utility displays them under NetWare scan logs and Windows scan logs,

respectively. You can select a number of acceptable errors; if this number is exceeded, the process aborts, allowing you to return to previous

steps to correct the errors.

lOn the Step 6 — Migrate tab, click Migrate.



Manually migrate (or use third-party utilities to migrate) object security permissions and system accounts, printer objects, application objects, and

other objects that MSDSS does not migrate from Bindery or NDS to Active Directory. (MSDSS migrates NetWare user accounts, groups, and

distribution lists for Bindery and NDS, and, for NDS only, MSDSS also migrates NDS organizational units and organizations.)

12. Upgrade your server(s) running NetWare to the Windows 2000 Server or Professional, or Windows Storage Server 2003, operating system.

13. On each Windows desktop in your NetWare network, uninstall Novell Client Access.



You must configure the desktops to join the Windows 2000 domain.

14. Optionally, upgrade NetWare clients (workstations) to the Windows 2000 Professional operating system.

15. Configure all client systems (both Windows and non-Windows), to join the Windows domain.



Be sure that the users know how to handle their password the first time they log in (for possible password options, see "MSDSS Password

Management" in "MSDSS Deployment: Understanding Synchronization and Migration)" at www.microsoft.com.



NOTE: The following step is optional.

Medium-Sized or Large Environment



An organization large enough to have WAN links probably selects to synchronize its networks temporarily while performing a gradual migration over time (up

to3monthsforalargenetwork),oritpreferstousesynchronizationtoestablishamixedNovell/Windowsnetworkonalong-term basis. If you plan a staged

migration, one-way synchronization is often the appropriate method.



After preparing as described above, perform the following steps (adjusted, if necessary, to your situation):

1. Back up your NetWare user and system data.

2. Install and configure a Windows domain controller (see the documentation that came with your operating system software).

3. Install the Novell Client for Windows from the Novell website at www.novell.com/download.

4. Install MSDSS from the NAS system DomainUtils share.



5. Log in to the NDS tree or Bindery server with administrative credentials.

6. Log in to the appropriate Windows domain as a member of the Domain Admins group.

7. On the MSDSS server, open the help files, and then print out the topics "To perform a one- way synchronization" or "To perform a two-way

synchronization."

8. Click the Start button, point to Programs→ Administrative Tools→ Directory Synchronization to start MSDSS, and then allow the prompts to guide

you through the following tasks:

a. Start the New Session Wizard (right-click MSDSS in the console tree).

b. Select Novell Bindery or Novell Directory Services (NDS) for one-way synchronization, or select Novell Directory Services (NDS) for two-

way synchronization.

c. Select One-way synchronization (from Active Directory to NDS or Bindery) or select Two-way synchronization (from Active Directory to

NDS and back).

d. Specify the path to the Active Directory container into which you want to copy items.

e. Accept the default domain controller in which to store the session database.

f. Specify the NDS Container or Bindery Container from which to copy items.

g. Provide the name and password of the Novell administrative account.

h. On the Initial Reverse Synchronization page, select Perform an initial reverse synchronization and specify the password options (such as Set

passwords to the user name).

i. On the Object Mapping Scheme page, click Default (to accept the default mapping for each source and target directory pair) or Custom (for NDS

only), and then click Object Mapping Table (to specify objects for which you want to establish a one-to-one relationship, regardless of the object

location in either directory tree).



MSDSS does not support custom object mapping for Bindery.

j. Also on the Object Mapping Scheme page, click Filters if you want to configure a filter for this synchronization session.

k. On the Session Name page, accept the default session name or specify a new name.

l. Click Finish.

9. If you selected one-way synchronization, perform all user, group, and NDS organizational unit container (OU) object management from Active Directory.

If you established two-waysynchronization,youcanmanageuser,group,andOUobjectsfromeitherActiveDirectoryorNDS.

10. If you plan long-term coexistence between Active Directory and NetWare, you are now finished, unless you want to migrate a subset of users, systems,

and/or files. If you plan to continue by migrating in stages from NetWare to Active Directory, perform the following tasks when convenient:

lInstall and configure File and Print Services for NetWare (to allow NetWare clients access to files and printers on Windows servers) and Gateway

Services for NetWare (to allow Windows clients access files and printers on NetWare servers).

lReplace services or applications that require NDS with commensurate software compatible with Active Directory. Perform large conversions (such

as GroupWise to Exchange) as separate projects.

lMigrate the pilot group of users and their files (Adapt the instructions from the migration steps provided in "Small Environment."). Get the pilot

group's feedback, and then set a schedule to migrate additional groups of users, according to the priorities you have established.

lMigrate the rest of the users as appropriate (For example, if you migrate the set of applications they use, migrate the users as well).



Network Adapter Teaming



Network adapter teaming allows the system to use the combined throughput of multiple network ports in parallel to increase performance or to provide fault

tolerance. Network adapter teaming on your NAS system supports the following modes:

lAdaptive Load Balancing (ALB)

lReceive Load Balance (RLB)

lSwitch Fault Tolerance (SFT)

lAdapter Fault Tolerance (AFT)

lIntel Link Aggregation

lFast EtherChannel (FEC) and Gig EtherChannel (GEC)

lIEEE 802.3ad Static

lIEEE 802.3ad Dynamic



NOTE: Installing and configuring the operating system MUI does not affect the language used by the NAS Manager.

NOTE: The default administrator user name is administrator and the default password is

powervault.

NOTE: The default administrator user name is administrator and the default password is

powervault.

NOTE: When creating or removing network adapter teams, the IP address of the NAS system's LAN connections changes. To prevent disconnection from

the NAS system during team configuration, connect a keyboard, monitor, and mouse to the NAS system when creating or removing teams. See

"Configuring Your System Using a Keyboard, Monitor, and Mouse" in "Initial Configuration" before configuring your teams.

Adaptive Load Balancing



Adaptive Load Balancing (ALB) is a simple and efficient method for increasing the NAS system's network transmission throughput. The ALB software

continuously analyzes transmission loading on each adapter and balances the load across the teamed ports as needed. Adapter teams configured for ALB also

provide the benefits of adapter fault tolerance. To use ALB, the Ethernet ports on the NAS system must be linked to the same Ethernet switch.



Receive Load Balancing



Receive Load Balancing (RLB) is a method for increasing the NAS system's network throughput by allowing reception from multiple addresses. RLB can only be

used in conjunction with ALB, and only the Ethernet ports connected at the fastest speed will be use to load balance incoming TCP/IP traffic. Simultaneous

reception only occurs from multiple clients.



Switch Fault Tolerance



Switch Fault Tolerance (SFT) uses two Ethernet ports connected to two separate switches to provide network availability of a second switch and Ethernet port

if the first Ethernet port, its cabling, or the switch fails.



Adapter Fault Tolerance



Adapter Fault Tolerance (AFT) provides the safety of an additional backup link between the NAS system and the hub or switch. If a hub, switch port, cable, or

Ethernet port fails, you can maintain uninterrupted network performance. AFT is implemented with a primary adapter and a backup, or secondary, adapter. If

the link to the primary adapter fails, the link to the secondary adapter automatically takes over.



Intel Link Aggregation



Link aggregation is a performance technology developed by Intel®and others to increase a system's network throughput. Unlike ALB, link aggregation can be

configured to increase both transmission and reception channels between your system and switch. Link aggregation works only with compatible Intel

switches. To use link aggregation, the Ethernet ports of the NAS system must be linked to the same Intel Ethernet switch.



Fast EtherChannel and Gig EtherChannel



Fast EtherChannel (FEC) and Gig EtherChannel (GEC) use performance technology developed by Cisco Systems to increase a system's network throughput.

Unlike ALB, FEC can be configured to increase both transmission and reception channels between your NAS system and switch. FEC and GEC work only with

compatible Cisco switches. To use FEC or GEC, the Ethernet ports of the NAS system must be linked to the same Cisco compatible switch.



IEEE 802.3ad Static



IEEE 802.3ad is a performance technology standard that increases a system's network throughput. IEEE 802.3ad is similar to the FEC standard developed by

Cisco. However, whereas FEC works only with FEC-compatible Cisco switches, IEEE 802.3ad works with all switches that support IEEE 802.3ad. To use IEEE

802.3ad, the Ethernet ports of the NAS system must be linked to the same IEEE 802.3ad switch.



IEEE 802.3ad Dynamic



IEEE 802.3ad Dynamic is a performance technology standard that increases a system's network throughput. IEEE 802.3ad Dynamic uses active aggregators in

software to determine team membership between the switch and the server software or between switches. IEEE 802.3ad Dynamic mode requires 802.3ad

Dynamic capable switches.

Telnet Server



The Telnet server works optimally for most installations. It accepts logins from a variety of clients, including the Telnet clients shipped with Windows 2000,

WindowsNT®, Windows95,andWindows98,WindowsXP,andWindowsServer2003operatingsystemsaswellasavarietyofcharactermodeterminal

clients from virtually any operating system. In addition, it can be configured to meet specific site requirements such as improving security, simplifying logins,

and supporting stream or console mode.



Authentication



The Telnet server supports Windows NT LAN Manager (NTLM) for authentication of client logins. NTLM allows users to be automatically authenticated to the

Telnet server based on their Windows NT login. This makes using Telnet completely transparent to users, while ensuring that clear text passwords do not

pass over the network. However, NTLM must be supported on the client side of the login as well.



When users are logged in to a system that is using NTLM login, they are restricted to local drives on that system. If they need to map network resources, they

can do so by explicitly mapping with full credentials.



Administration



The Telnet server is administered using the NAS Manager.



FTP



Enabling FTP Protocol

Using Secure Sockets Layer

NOTE: The default administrator user name is administrator and the default password is powervault.



This section explains how secure sockets layer (SSL) are used in the NAS system. It also explains how to use your own certificate, if you have one, and how to

regenerate your certificate.



Introduction to SSL Certificates



Certificates contain information used to establish system identities over a network. This identification process is called authentication. Although authentication

is similar to conventional forms of identification, certificates enable Web servers and users to authenticate each other before establishing a connection to

create more secure communications. Certificates also contain encryption values, or keys, that are used in establishing an SSL connection between the client

and server. Information, such as a credit card number, sent over this connection is encrypted so that it cannot be intercepted and used by unauthorized

parties.



Two types of certificates are used in SSL. Each type has its own format and purpose. Client certificates contain personal information about the clients

requesting access to your site, which allows you to positively identify them before allowing them access to the site. Server certificates contain information

about the server, which allows the client to positively identify the server before sharing sensitive information.



Server Certificates



To activate your Web server's SSL 3.0 security features, you must obtain and install a valid server certificate. Server certificates are digital identifications

containing information about your Web server and the organization sponsoring the server's Web content. A server certificate enables users to authenticate

your server, check the validity of Web content, and establish a secure connection. The server certificate also contains a public key, which is used in creating a

secure connection between the client and server.



The success of a server certificate as a means of identification depends on whether the user trusts the validity of information contained in the certificate. For

example, a user logging on to your company's website might be hesitant to provide credit card information, despite having viewed the contents of your

company's server certificate. This might be especially true if your company is new and not well known.



For this reason, certificates are sometimes issued and endorsed by a mutually trusted, third-party organization, called a certification authority. The certification

authority's primary responsibility is confirming the identity of those seeking a certificate, thus ensuring the validity of the identification information contained in

the certificate.



Alternatively, depending on your organization's relationship with its website users, you can issue your own server certificates. For example, in the case of a

large corporate intranet handling employee payroll and benefits information, corporate management might decide to maintain a certificate server and assume

responsibility for validating identification information and issuing server certificates. For more information, see "Obtaining a Server Certificate From a

Certification Authority."



PowerVault 745N Certificate



By default, your NAS system has a self-generated and self-signed certificate. The configured SSL port is 1279.



Using a Custom Certificate



If a certification authority is present in the network, the administrator can choose to change the default certificate for your NAS system. The administrator must

use the wizards to first request a certificate and then apply it to the NAS system.



Obtaining a Server Certificate From a Certification Authority



Find a certification authority that provides services that meet your business needs, and then request a server certificate.



NOTE: If you are replacing your current server certificate, the Internet Information Server (IIS) continues to use the old certificate until the new request

has been completed.

NOTE: For the latest list of certification authorities supporting IIS, see the Microsoft Security website. In the By Category list, select Certification

Authority Services.



To obtain a server certificate, perform the following steps:

1. Log in to the NAS Manager.

2. Click Maintenance, and then click Remote Desktop.

3. Log in to the NAS system as an administrator.



4. Double-click the NAS Utilities icon on the NAS system's desktop.

5. In the NAS Utilities window, double-click Administrative Tools, and then double-click Internet Information Services.

6. Double-click the local system to expand it, and then double-click Web Sites.

7. Right-click the Administration icon, and then select Properties.

8. In the Administration Properties window, click Directory Security.

9. Click Server Certificate to access the Web Server Certificate Wizard.

10. Use the Web Server Certificate Wizard to create a certificate request.

11. Send the certificate request to the certification authority.



The certification authority processes the request and sends you the certificate.



12. Use the Web Server Certificate Wizard to install your certificate.



For more information about SSL, see the Internet Information Server online help.



Using DFS



DFS creates a logical, hierarchical view of file shares that exist on servers distributed in one or more Windows 2000/Windows Server 2003 domains. DFS can

help you manage file resources on distributed enterprise networks, and it enables users to locate files across the network without needing to know the

physical server on which the data is stored.



Two methods are available to deploy DFS—stand-alone or integrated—into the domain.



Stand-alone DFS does not require Active Directory (AD), and does not have the full functionality of DFS. It is mostly intended for backwards compatibility and

support for networks without AD. Domain-integrated DFS takes full advantage of all the intended functionality by utilizing AD. Some of the functionality domain-

integrated DFS offers is load-balancing, fault-tolerance, and Kerberos-based security.



Creating a Standalone DFS Root

1. Use the Windows operating system to create a directory on the NAS system.



This directory will become the DFS root

2. Right click the directory you created and select Sharing and Security.

3. Click Share this folder. and then click OK.

4. Access the DFS utility.

a. In the NAS Manager, click Maintenance.

b. Click Remote Desktop, and then log in to the NAS system as an administrator.



NOTE: The default administrative user name is administrator and the default password is powervault.

NOTE: Some certification authorities require you to prove your identity before processing your request or issuing you a certificate.

NOTE: OnlyoneDFSrootisallowedontheStandardEditionoftheMicrosoftWindowsStorageServer2003operatingsystems.


The system can also be connected through the http shares page on port 80, which is not SSL-encrypted. It is recommended to disable http on the Shares 
page. See "Disabling HTTP Shares." 

Passwords  

The default administrator user name for your NAS system is administrator and the default password is powervault. Change the default administrator 
password as soon as possible. See "Changing the Administrator Password." Additionally, Dell recommends the following password practices for your NAS 
system: 
lUse passwords that are longer than six characters. 
 
lDo not use blank or simple passwords. 
 
lDo not use dictionary words. 
 
lDo not use personal information such as name, children's names, birth dates, and so forth. 
 
lUse a mix of numerals and upper and lowercase letters. For example, Rs4326tH. 
 

FTP and Telnet  

For security reasons, FTP and Telnet are disabled by default on the NAS system. If either of these protocols are enabled on a share on the NAS system and 
you need to disable them, see "Removing a Protocol From the Share." 

Antivirus Software  

Dell recommends using antivirus software on your NAS system to protect against viruses. 

Microsoft Security Updates  

Microsoft regularly posts security update patches to its website at microsoft.com. Dell recommends that you regularly check to ensure that your NAS system 
has the most recent security update. 


Apple Environments



If you are using your NAS system in an Apple environment, install the Microsoft®User Authentication Module (UAM) on the NAS system. If AppleTalk is not

installed on the NAS system, client access is not encrypted. See "Services for Macintosh" for more information.



Secure Socket Layer (SSL) Certificates



SSL certificates enable Web servers and users to authenticate each other before establishing a connection to create more secure communications. See "Using

Secure Sockets Layer" for information.



Microsoft Baseline Security Analyzer



Use the Microsoft Baseline Security Analyzer (MBSA) to search for any security vulnerabilities. MSSA scans Windows-based servers for common security

misconfigurations. The tool scans the operating system and other installed components such as Internet Information Services (IIS). MBSA also checks systems

for missing security patches, and recommends critical security patches and fixes.



Additional Security Recommendations



In addition to the practices mentioned in "Standard Security Recommendations," Dell recommends the following practices to ensure security:

lFormat all volumes as NTFS.

lDisable automatic log on.

lDisable the guest account.

lDo not install IIS sample applications.

lDisable parent paths.

lMove the MSADC and Scripts virtual directories from the default website to another location.



Ensure that you place appropriate restrictions on any Anonymous Logon groups. To allow UNIX®users who do not have Windows user accounts to access

resources on a system running Windows, you must explicitly add the Anonymous Logon group to the Everyone group and assign the Anonymous Group

appropriate permissions. For more information, see "Server for Network File System (NFS)."



Maximum Security Recommendations



This section provides information about practices recommended for maximum security on your NAS system.

lAllow no more than two administrators on the NAS system.

lDo not allow passwords that have no expiration date.

lEnable Logon Success and Logon Failure auditing.

lDisable unnecessary services.

lDisabling unnecessary services also increases performance.

lRemove the IISADMPWD virtual directory.

lEnable application logging options for all Web and FTP sites.

lEnsure that Internet Explorer zones have secure settings for all users.

lUse the NAS system only for shares and services that are actively used.

lDisable http sharing if http shares are not used.



Disabling HTTP Shares

1. Log in to the NAS Manager.

2. Click Shares.

3. On the Shares page, click Sharing Protocols.

4. Click HTTP and then click Properties.

5. Click Security.
