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 g roup are then moved to this
iSCSI volume, All-in-One Storage Manager (ASM) will d iscover 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 D PX
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 utili ty 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 c ancels the backup job and notifies Exchange that the backup
did not complete successfully.
