About recovery after hardware failure

A system failure that results in the loss of either database or transaction log volumes leads to unplanned downtime. If the failure does not affect the disk or disks where the snapshot set resides, you can recover from the failure and resume normal email operations faster by using the snapshot set than you could by restoring from your backup media.

You can use the vxsnap utility to recover a database after production volumes are lost due to a hardware failure.


The methods described in these procedures are the simplest possible and assumes that a volume snapshot set is already available before proceeding with the restore operation. However, if the snapshot set is not available, you will need to recover it from your tape backup.
