HP Application Recovery Manager software Integration guide (March 2008)
Copy of replica data with the source volume not retained
With this method, the source volume is directly overwritten by the replica. The old
source volume is not retained and if the restore session fails, the original application
data residing on the source volumes is lost.
You can select to retain the replica and thus enable to perform another restore from
this backup.
Advantages
• Disk group of the source volume is not changed after instant recovery.
• Physical location of the application production data remains the same.
• Another restore from the same backup is possible.
Disadvantages
• Restore is not as fast as with the "switch of disks" method.
• The "old" source volume is lost during restore.
To perform this type of restore, select the Copy replica data to the source location
option and clear the Retain source for forensics option in the Application Recovery
Manager GUI.
HP StorageWorks EVA considerations
• After instant recovery, the replica used in the session can become the source
volumes (physical location of the original application data changes). This depends
on the restore options you select in the GUI.
Additionally, if a replica resides in another disk group than the source volumes,
this replica disk group becomes the disk group of the source volumes.
• Depending on the restore options you select in the GUI, the restored replica can
be deleted from the replica set after instant recovery. In this case, you cannot run
instant recovery using the same session ID again.
• If you restore using HP StorageWorks EVA, before instant recovery, it is
recommended to check if the SMI-S CIMOMs were configured properly in the
Application Recovery Manager cell by running the omnidbsmis -ompasswd
-check [HostName] command.
This command performs a health check of you environment, which may help
identify such potential problems as wrong user name or password provided, a
broken network connection, a DNS resolution problem, and so on.
