HP ProLiant Storage Server release notes (5697-7750, November 2008)

All-in-One Storage M anager
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 i n 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.
Workaroun
d
The 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 an
d/or Restore operations in ASM may fail if there is more than one File Volume
configure
donaniSCSI-BasedLUN.
Description
The Backup and/or Restore operations in ASM may fail if there is more than one
File Volume (par tition) 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 M anager, the Create Volum e
task m
ay fail in the following wi z ards:
• Host a
nExchangeStorageGroupWizard
• Creat
eaShareFolderWizard
• Host
a SQL Server D atabase Wizard
• Host
aUser-Defined Application Wizard
This
is due to an error in Microsoft Virtual Disk Service (VDS).
Workaround
Restart the specific wizard to l aunch 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,

System at h

Issue:
Data protection settings are not modified for storage areas that are promoted by ASM
Description
If data protection settings (replication, sn apshots, and backup) are applied to a
remote user-defined storage area, and then a SQL Server da tabase or Exchange
database is manually migrated to this storage area, ASM automatically promotes
the application to a SQL or Exchange Storage a rea during the discover y p rocess.
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.
