Data Protector Express
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
Due to object model changes in AiO 1.3 and later, it is not possible to perform an
overwrite restore when restoring data that was backed up prior to AiO 1.3. The
data may be restored to an alternate location and then manually moved to the
original location.
Use the Different Location Restore option to restore the data to an alternate location
of your choice. The data can then be moved manually, overwriting the existing files.
It is possible to manually create a virtual hard disk on AiO 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, and the following error is written
to the Windows application event log on the AiO 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 storage group
to AiO. When the logs are not found, the checksum fails and ASM cancels the
backup job and notifies Exchange that the backup did not complete successfully.
