HP Storage Server Management console user interface

This section describes issues with the user interface for the HP Storage Server Management console.

HP Storage Server Management console user interface

Issue: While connected to the HP Storage Server Management console using the web browser method,

an error is shown if the user tries to open a shared folder

Description

While connected using the web browser method (http://machine-name:3201

or https://machine-name:3202), if the user navigates to HP Storage Server

Management > Share Folder Management > Shared Folders, right-clicks on a

shared folder, and selects Open, an error is shown. In addition, the desktop icons,

start menu, and task bar appear on the screen. This is because the action of

opening a shared folder depends on the Windows shell, which is not running by

default while connected through a web browser.

HP Storage Server Management console user interface

Workaround Connect directlytothestorageserverorviaRemoteDesktop.

Issue: The pie chart under HP Storage Server Management > Storage Management may indicate a

larger amount of disk space than actually exists

Description

This issue may occur if both of the following are true:

•A hard quota is set and enabled on the root folder of one or more volumes.

•A volume with a hard quota on the root folder also has Single Instance Storage

(SIS) enabled.

This is due to an interoperability issue between directory quotas and SIS.

Workaround Disable the hard quota on the root folder of the volume, or change the hard quota

to be a soft quota.

Issue: Adding multiple instances of the HP Storage Server Management snap-in to one console causes

information to display incorrectly

Description If multiple instances of the HP Storage Server Management snap-in are added

to one console, all instances will reﬂect information about only the ﬁrst server

speciﬁed.

Workaround Open a new MMC console for each instance of the snap-in.

Issue: The Storage Server and Microsoft MMC quota plug-in fail when creating a new quota

Description

When creating a new quota using the HP Storage Server Management

console, the creation may fail with the event log message: A File Server

Resource Manager configuration file or import-export file

is corrupted. If the corrupt file is a configuration file,

it is required that the system or volume be restored from

backup. If the file is an import-export file, export the

items again and retry the operation without editing the

file contents.

Workaround

If the volume has existing quotas, recover the volume from backup. If the volume

does not have existing quotas, use an Administrator login to rename the <Drive

Letter>:\System Volume Information\SRM\quota.xml ﬁle and try to

create the quotas again. Recover from backup if the creation continues to fail.

Issue: After installing a Multilingual User Interface (MUI), the HP Storage Server Management console

might incorrectly display unsupported MMC snap-ins

Description On the ﬁrstrebootafterinstallinganewMUIfromtheHPLocalizationKitontoan

HP ProLiant Storage Server, the HP Storage Server Management console might

display the Clustered Gateway Management MMC snap-in, which is not supported.

Workaround

There are two workarounds for this issue:

•Reboot the server.

1. Close the HP Storage Server Management console.

2. Restart the HP Storage Server Management service.

3. Reopen the HP Storage Server Management console.

Issue: Creating quotas on a newly-installed cluster might cause File Server Resource Manger to fail

with an unexpected error

Storage Server release notes 5

HP Storage Server Management console user interface

Description

After creating a cluster, if you try to create a quota using the HP Storage Server

Management console (Storage Management > Share and Storage Management

> File Server Resource Manager > Quota Management > Quotas), the Quota

Creation window might not open, the File Server Resource Manager will fail with

the message An unexpected error occurred,andanentrywillbeadded

to the event logs.

Workaround

1. Close the HP Storage Server Management console.

2. Restart the File Server Resource Manager service.

3. Reopen the HP Storage Server Management console.

Issue: Task Viewer displays “Load failed” message for ASM tasks

Description

When an ASM wizard-based task is initiated from the HP Storage Server

Management console, the Task Viewer indicates that the job has failed with a Load

failed error message. This behavior applies to any of the ASM wizard-based tasks:

Host an Exchange Storage Group, Create a Shared Folder, Host a SQL Server

Database, Host a User-Deﬁned Application, and Create a Virtual Library.

Workaround

The message can be ignored. Click All-in-One Storage Manager in the HP Storage

Server Management console navigation pane. The ASM Task Viewer conﬁrms that

the task is queued to run or already running.

Issue: HP Storage Server Management console unavailable using the web browser method

Description

When using the web-based Remote Desktop Protocol (RDP) client to connect to

https://machine-name:3202 and http://machine-name:3201, an empty box

appears in place of the HP Storage Server Management console. This issue occurs

because the ActiveX version of the RDP client is an unsigned plugin.

Workaround

Using the Windows Remote Desktop Connection client, connect to

\\machine-name:3202 for the secure connection and \\machine-name:3201

for the unsecure connection.

All-in-One Storage Manager

This section describes issues related to HP StorageWorks All-in-One Storage Manager (ASM) version

3.7.0.88.

All-in-One Storage Manager

Issue: Exchange,SQLServer,anduser-deﬁned application data restored to an alternate location cannot

be deleted

Description

Thedatacannotbedeletedduetoinsufﬁcient privileges. All iSCSI LUNs created

by All-in-One Storage Manager on a Windows server as part of hosting Exchange,

SQL Server, and user-deﬁned application storage, contain System Volume

Information, a hidden system folder. This folder is by default only accessible to

the SYSTEM user, and not to the Administrators group. There may also be other

similarfolders,suchasSIS Common Store,ifSingle Instance Storage is enabled

on the volume.

Workaround

Change the privileges as follows:

1. Navigate to the System Volume Information folder in the restored data.

2. Right-click the folder and select Properties.

3. On the Security tab, add the Administrators group and select Full Control

for its permissions.

The folder can now be deleted by an administrator. Repeat this process for any

other folders that are inaccessible by administrators.

All-in-One Storage Manager

Issue: Exchange Server 2007 logs an error (Event ID 9782 ) in event log when a snapshot is taken

from All-in-One Storage Manager.

Description

When a snapshot of an Exchange 2007 storage group is taken by All-in-One

Storage Manager, the snapshot succeeds but Exchange logs an error in the

application event log on the Exchange server. This error is expected, and occurs

because All-in-One Storage Manager intentionally does not mark the VSS snapshot

as successful. When a VSS snapshot is reported as successful, Exchange truncates

its log ﬁles for the storage group. This may not be desirable in the case of a

snapshot which does not typically provide the same data protection as a backup

done using a backup application such as the integrated Data Protector Express.

WorkaroundThe error may be ignored. The successful snapshot will appear in the list of

snapshots in the Data Protection tab of All-in-One Storage Manager.

Issue: Backup and/or Restore operations in ASM may fail if there is more than one File Volume

conﬁguredonaniSCSI-BasedLUN.

Description The Backup and/or Restore operations in ASM may fail if there is more than one

File Volume (partition) conﬁgured on an iSCSI-Based LUN (disk).

Workaround

Do not perform backup or restore operations in ASM on storage where more than

one File Volume is hosted on a single iSCSI LUN. ASM never provisions more than

one volume on iSCSI LUNs, and this situation will not be encountered for storage

provisioned by ASM.

Issue: Migrating storage using All-in-One Storage Manager may cause an error during volume creation

Description

When migrating storage using the All-in-One Storage Manager, the Create Volume

task may fail in the following wizards:

•Host anExchangeStorageGroupWizard

•CreateaShareFolderWizard

•Host a SQL Server Database Wizard

•Host aUser-Deﬁned Application Wizard

This is due to an error in Microsoft Virtual Disk Service (VDS).

Workaround

Restart the speciﬁc wizard to launch the task again.

In some cases, the Create Volume task will fail after storage has already been

provisioned and an iSCSI LUN has been created on the storage server. If this occurs,

running the wizard again will result in another iSCSI LUN (vhd ﬁle) being created

on the storage server and the initial iSCSI LUN will take up extra space without

being utilized. For information about how to properly delete the unused iSCSI LUN,

seethewhitepaperReclaiming storage on the HP StorageWorks All-in-One Storage

System at http://h71028.www7.hp.com/ERC/downloads/4AA1-1026ENW.pdf.

Issue: Data protection settings are not modiﬁed for storage areas that are promoted by ASM

Description

If data protection settings (replication, snapshots, and backup) are applied to a

remote user-deﬁned storage area, and then a SQL Server database or Exchange

database is manually migrated to this storage area, ASM automatically promotes

the application to a SQL or Exchange Storage area during the discovery process.

ASM does not, however, adjust the data protection settings that were originally

applied to the area. This may lead to failures when taking snapshots, running

backups, or running replication.

Storage Server release notes 7

All-in-One Storage Manager

Workaround

When SQL Server or Exchange databases that are part of user-deﬁned storage

areas are promoted to SQL or Exchange storage areas in ASM, disable and delete

all data protection settings for those areas (replication, snapshots, and backup)

and reset them using ASM.

Issue: Replicating a storage component whose application data exists in a single iSCSI LUN results in

extra space utilization on the replication target

Description

When a single iSCSI LUN is presented to a SQL or Exchange server, the database

ﬁle and database transaction log ﬁlearebothcreatedonthevolumecontainedin

the iSCSI LUN. If the iSCSI LUN was created on the storage server as a user-deﬁned

application, ASM will discover that the database ﬁles are now in the volume and it

will promote the user-deﬁned application to a SQL Server or Exchange application

instance. If the SQL Server or Exchange application instance is replicated to

another system, the iSCSI LUN is replicated to the target system twice: once for the

database ﬁle and again for the log ﬁle.

In general, the amount of space used on the replication target is equal to the size

of each iSCSI LUN that contains multiple components multiplied by the number

of components in that iSCSI LUN. If multiple components exist in multiple iSCSCI

LUNs, the sum of the product of the sizes is the total consumed space. Snapshot

space usage is similar.

For example, a single iSCSI LUN of 200MB that contains a volume that has

both the database ﬁle and the log ﬁle would consume 400 MB of space on the

replicationtarget(200MBx2=400MB).Likewise,anExchangeserverwithone

storage group of three mail stores on one iSCSI LUN of 500MB and the log and

public store on a separate iSCSI LUN of 250 MB would consume 2000MB of

spaceonthereplicationtarget(500MBx3+250MBx2).

Workaround

As a best practice, when conﬁguring storage for SQL Server and Exchange

databases, create the database ﬁles on one iSCSI LUN and create the associated

log and system ﬁlesonaseparateiSCSILUN.Thisway,whenstorageareasare

replicated, there will be one component per iSCSI LUN and space will be utilized

on the replication target more efﬁciently.

Issue: Application credential error appears while running the Host a SQL Server Database Wizard

Description

When attempting to host a SQL Server 2008 database using the Host a SQL Server

Database Wizard, an application credential error message may appear. This error

might appear because SQL Distributed Management Objects (SQL-DMO) is not

installed with SQL Server 2008 by default.

Workaround

Before attempting the following workaround, check to make sure that you have

properly entered your SQL Server 2008 credentials. If your credentials are correct

and the error message still appears, install SQL-DMO.

To install SQL-DMO, run the SQL Server 2005 Backwards Compatibility installer:

1. On the SQL Server 2008 Installation Media, navigate to the \x64\Setup\x64\

folder on 64–bit application servers and \x86\Setup\x86\ on 32–bit

application servers.

2. Double-click SQLServer2005_BC.msi.

3. Follow the on-screen instructions.

After installing SQL-DMO, run the Host a SQL Server Database Wizard again.

The wizard will complete without error.

Issue: ASM attempts to create non-existent storage during discovery

All-in-One Storage Manager

Description

If you use a non-ASM tool (such as the Array Conﬁguration Utility, for example) to

modify storage settings, you must allow ASM time to recognize those new settings

during the discovery process. If you attempt to perform storage operations before

the discovery process is complete, ASM will erroneously attempt to perform storage

operations such as growing non-existent logical disks.

Workaround When modifying storage settings outside of ASM, allow enough time for the ASM

discovery process to recognize those new storage settings before performing any

other ASM operations.

Issue: When attempting to provision storage on ASM, an error message appears

Description When attempting to provision storage, an error message indicating that “no

storage could be found or created to satisfy the request” may be issued. This error

can appear when attempting to provision storage across multiple disk types.

Workaround

Virtual arrays that span multiple disk types cannot be created. When provisioning

storage, the maximum amount of space you can allocate is limited by the largest

amount of space available for a single disk type. You cannot completely utilize the

spaceonallofthedisksifthedisksareofdifferenttypes.

Data Protector Express

This section describes issues related to HP StorageWorks Data Protector Express (DPX), a service required

to enable data protection features on the HP All-in-One Storage Manager. Note that HP StorageWorks

Data Protector Express is not installed on HP ProLiant Storage Servers by default. The following issues

apply only to HP ProLiant Storage Servers with DPX installed and enabled.

NOTE:

Changes made using Data Protector Express are not always reﬂected in All-in-One Storage Manager.

Data Protector Express

Issue: Changes made to a backup using Data Protector Express are not always reﬂected in All-in-One

Storage Manager

Description If you use Data Protector Express to change the rotation type associated with a

backup to Custom rotation, the change is not reﬂected in All-in-One Storage

Manager.

Workaround

Data Protector Express can be used to change the rotation type of a backup to

Custom rotation,however,thischangewillnotbereﬂected in All-in-One Storage

Manager. If you need to use a custom rotation, HP recommends that you continue

to use Data Protector Express to make any further changes to the backup.

Issue: Data Protector Express may fail to start with "Service not found" error

Description

When attempting to start Data Protector Express, the following error may be

displayed:

Code: 59 (0x3b)

Message: Service not found

Description: The desired service was not found. Either the

service is no longer active, or the machine providing the

service is unavailable at this time.

Storage Server release notes 9

Data Protector Express

Workaround

Check the dpconfig.ini ﬁle at C:\Program Files\HP\Data Protector

Express\config. In particular, the isDatabaseServer setting should be Yes.

Other entries may vary depending on your conﬁguration.

The ﬁle should have a [conﬁguration] section similar to the following:

[configuration]

lastUser=ASMbackup

nodeGuid={00001001-44BF7770-0010D9E7-0018CAB0}

nodeName=STORAGEWORKSAIO

databaseServerAddress=localhost

isDatabaseServer=Yes

databaseServerName=Data Protector Express Storage Domain

disableNetwork=Yes

remoteAdmin=No

Issue: Backup job fails for Exchange storage groups that were manually migrated to the storage server.

Description

It is possible to manually create a virtual hard disk on the storage server using

the Microsoft Software iSCSI Target snap-in. This disk may then be assigned to

a target, allowing an iSCSI initiator on the Exchange server to access the disk

as a local volume.

If the logs and database(s) of an Exchange storage group are then moved to this

iSCSI volume, All-in-One Storage Manager (ASM) will discover the Exchange

Storage Group, and present it as an application in the ASM user interface. This

will allow you to conﬁgure data protection for the application and schedule a DPX

backup; however, when the backup job runs, it fails.

The job status in DPX will be operator canceled,andthefollowingerroriswritten

to the Windows application event log on the storage system:

Stopping backup job '<job name>' due to checksum

verification failure.

The error occurs because ASM performs checksum veriﬁcations using the

eseutil.exe utility on Exchange databases and logs before backing up the ﬁles.

Databases and logs are expected to be found in separate volumes as a best

practice method employed by ASM when a wizard is used to migrate an Exchange

storagegrouptothestorageserver. Whenthelogsarenotfound,thechecksum

fails and ASM cancels the backup job and notiﬁes Exchange that the backup

did not complete successfully.

Data Protector Express

Workaround

Manually create another iSCSI virtual hard disk and make it accessible to the

Exchange server:

1. Use the Exchange Management Console to move the storage group path for

the log ﬁles andsystemﬁles to the new volume, leaving the database at the

original iSCSIvolume.

2. After modifying the paths in Exchange, click Refresh in the ASM user interface

to force a discovery.

3. The application area for log ﬁles will now show an alert. Right click on this

area and select Remove from view.

4. Another discovery will be performed and ASM will restore the log ﬁle area

into the user interface with corrected properties, such as the new location on

the Exchange server.

For backup jobs from ASM to work properly, each database and the log

ﬁles/system ﬁles must be on a separate iSCSI volume. For example, if a storage

group contains one mail store and one public folder store, three iSCSI volumes

should be used, one for each database, and one for the log and system ﬁles.

Issue: Performing a “Remove from View” on a Virtual Library causes the library to appear as a

User-Deﬁned application.

Description

If a virtual library is deleted from Data Protector Express, and then the Remove

from View option is used on the virtual library in All-in-One Storage Manager,

the virtual library is removed from the Data Protection view, but appears in the

User Deﬁned view.

Workaround

1. Use Data Protector Express to stop and then delete the Virtual Library Device.

a. In Data Protector Express, select the Devices icon from the Favorites pane

on the left.

b. Intherightpane,navigateuntilthedesireddeviceisdisplayed.

c. Right-click the Virtual Library device and select Stop.

d. After the device has been stopped, right-click again and select Delete.

2. Delete the storage folder used by Data Protector Express to store the backup

data. The storage folder path can be found by right-clicking on the virtual

library in All-in-One Storage Manager, selecting Properties,andthenselecting

the Storage tab.

3. Right-click on the virtual library in All-in-One Storage Manager and select

Remove from view.

HP StorageWorks Storage Mirroring

This section describes issues related to HP StorageWorks Storage Mirroring (SWSM), a service required

to run replication on the HP All-in-One Storage Manager. Note that HP StorageWorks Storage Mirroring

is not installed on HP ProLiant Storage Servers by default. The following issues apply only to HP ProLiant

Storage Servers with SWSM installed and enabled.
