Known Issues

• The diagnostic report for the Distributed File System (DFS)

replication group generates an error.

When you create a diagnostic report for a replication group, the

following error message appears:

The health report cannot be generated. Error

HRESULT E_FAIL has been returned from a call to

a COM component

Microsoft addresses this issue with Microsoft Knowledge Base

article 912154, which is available on the Microsoft Support website

•

Internet Information Services (IIS) is installed by default through the

Dell PowerEdge™ Installation and Server Management

While installing Microsoft Windows

Unified Data Storage Server 2003 x64

using the

Dell

PowerEdge Installation and Server Management

CD,

the

IIS

component is not selected in the

Advanced

tab. After the

installation is complete, all the IIS components are installed on the

system even when the

IIS

component is not selected.

6Important Information

• Users with administrative privileges can create logical unit

numbers (LUNs).

All users with administrator rights can successfully perform operations

in the

Storage Manager for SANs

and in the

Storage Provision

wizard

even though they are not a part of the privileged user’s list. This issue

also occurs when invalid users are added to the privileged user’s list on

both storage processors.

•

The Provision a Shared Folder wizard allows the creation of quota on

the same path multiple times

The

Provision a Shared Folder

wizard allows the creation of quota and

File Screen on the same path multiple times if a different share name is

used. When the user provides a different share name to the same

physical location in the

Share Provision

wizard, creation of quota is

enabled even when the

Apply Quota

check box is not selected in the

Quota Policy

window. The existing quota and File Screen get

overwritten without a warning.

•

Sorting operation on size does not work as expected

In the PowerVault NX1950 console, the columns are sorted based on

the character value instead of the numeric value. This issue occurs in

the following wizards:

– Create LUN wizard — Subsystem and Type

– Provision a Shared Folder wizard — Shared Folder Location

– Provision Storage wizard — LUN Type

For example, the rows are sorted depending on the string value such as

1, 10, 100, 2, 20, 200, and so on instead of 1, 2, 10, 20, 100, 200.

•

Files to include and files to exclude in a File Screen have the same file

extensions

In the

Files Group Properties

window, the

Files to include

and

Files to

exclude

lists can have the same file extensions. During the File

Screening operation, the files in the

Files to include

list have higher

precedence over the files in the

Files to exclude

list.

Important Information 7

•

Displays product name as PowerVault NX instead of PowerVault

NX1950

In Server Assistant, IT Assistant, and Dell Remote Access Controller

(DRAC) the product name is displayed as PowerVault NX instead of

PowerVault NX1950.

•

Cannot restore Java remote desktop controller (RDP) after it is

minimized

It is not possible to restore a Java RDP session to the full screen mode

after it has been minimized. Attempting to restore the session appears

unrecoverable.

To work around this issue, close and relaunch the browser to establish

the session with the remote system.

•

Specify Credentials for the administrator account states that the

account name can be changed

In the

PowerVault NX1950 Configuration Tasks

wizard,

Specify

Credentials

for the administrator’s account incorrectly states that the

user can change the account name of the system. This information is

incorrect as the user can only change the password. Attempting to

change the administrator account errors out.

•

Storage Provision wizard fails when formatting a volume less than

8MB

When a user creates a LUN and a volume of less than 8 MB using the

Storage Provision

wizard, the volume cannot be formatted. This is a

known issue

•

The PowerVault NX1950-specific video driver is not present on the

Dell PowerEdge Installation and Server Management

The standard Windows video driver is present on the

Dell PowerEdge

Installation and Server Management

CD. If the operating system is

reinstalled, you can download the PowerVault-specific video driver

from the Dell Support website at

8Important Information

•

Displays Unspecified user error message when a user with no

administrator privileges starts/stops the network file system (NFS)

When a user tries to start or stop the

User Name Mapping/Client for

NFS/Server for NFS

service from the

Microsoft Service for NFS

, the

following error message is displayed:

Unspecified user

This issue is behaving as designed because the user is trying to perform

an operation that requires administrator privileges.

•

iSCSI target allows multiple initiators to access a single virtual disk

If the same virtual disk is added to different targets or a target with

multiple clients from the initiator machine, the user can overwrite the

data that belongs to other users. The addition of a new file or a folder

will not be transparent unless the user restarts the initiator service.

This issue results in loss of data as the user on one initiator will be

overwriting data that belongs to other users.

•

Multiple attempts to configure the array reports the array type as

Unknown in a storage array setup

While running the

Dell Storage Initialization

wizard during the initial

configuration, multiple attempts to the initial wizard in the

Array log

page reports the array type as

Unknown

and is behaving as

designed. It is not possible to read the array type unless the privileged

user list on the array is empty or if the privileged user list is manually

set up.

To work around this issue, configure the array completely using the

Dell Storage Initialization

wizard at least once.

•

Uninstalling and reinstalling File Server Resource Manager (FSRM)

shows two snap-ins in the PowerVault NX1950 console

One snap-in is displayed under

Share and Storage Management

and

snap-in is removed from the

PowerVault NX1950 console:

Unmanaged Exception in Managed code Snap-in

• PowerVault NX1950 console is limited to 26 drives.

Only 26 drives are available when using the PowerVault NX1950

console. If the number of drives are exceeded, the PowerVault NX1950

console crashes when the user tries to launch the

Create LUN

wizard

from the

Storage Manager for SANs

snap-in. The PowerVault NX1950

console continues to operate only if the user selects

Unload snap-in

and continue running

with the exception that the

Storage Manager

for SANs

snap-in is unloaded. If the user continues to run PowerVault

NX1950 console, the console will crash.

To work around this issue, create LUNs using DISKRAID.

• More Actions displayed instead of List of Actions.

The

Action

pane in the PowerVault NX1950 console displays

Actions

instead of

List of Actions

More Actions

displays the menu.

This issue is observed in the following snap-ins:

– Microsoft Services for NFS

– iSCSI Software target

– Indexing Service

– Local User and Groups

– Event Viewer

– Performance Logs and Alerts

10 Important Information

PowerVault NX1950 console 3.0 help.

The help links listed in the

Dell Management Tools

snap-in point to

the help page for the PowerVault NX1950 console 3.0. This issue

occurs as help pages are not available for the tools listed in the

Dell Management Tools

snap-in.

• Assign LUN wizard shows the option, Don't assign LUN at this time.

When using the

Assign LUN

wizard the

Don't assign LUN at this time

option is displayed in addition to the assign LUN options. This issue is

working as designed.

• Virtual disk service (VDS) operations fail when the password is set on

an array managed through the Dell Storage Initialization wizard.

VDS operations on a Dell PowerVault MD3000 array fail unless the

password is set using the

SMRegTool

. The

SMRegTool

is a part of the

VDS provider and is located in the installation directory.

• The Share and Storage Manager does not indicate a shared volume

for File Screen.

The shared volume for File Screen is usually shown with a check mark

in the

Share and Storage Manager

window. This issue occurs due to a

display problem but File Screen is active.

•

The Storage Manager for SANs snap-in does not remove the available

driver letters assigned to a volume

When two

Create LUN

operations are performed in rapid succession,

the

Storage Manager for SANs

snap-in does not remove the available

driver letters. This issue is indicated by an error message related

to volume creation failure. To work around this issue, use the

Disk Management

snap-in to create volumes manually.

•

Deleted drives under the Disk Management snap-in causes the

PowerVault NX1950 console to crash

After a drive has been deleted using the

Storage Manager for SANs

the drive continues to display under the

Disk Management

snap-in.

If the user clicks the deleted drive, the PowerVault NX1950 console

crashes. To work around this issue, use the

Share and Storage

Manager

snap-in to delete the drive.
