Recovery after hardware failure
You can use the -r switch to perform a VSS-integrated recovery after a hardware failure. The following recovery scenarios are possible if the complete snapshot set including the XML metadata file is available:
Table: Available recovery type after missing production volume
Scenario | Database Volumes | Transaction Logs Volume | Recovery |
|---|---|---|---|
Scenario I | One or more volumes are missing. | Missing | point in time |
Scenario II | All volumes are missing. | Available | point in time or point of failure |
Warning:
Before using the vxsnap restore command, verify that you have correctly assigned the drive or mount point to each volume.
It is important that each of the tasks be performed exactly as described.
See Tasks for recovering after hardware failure.
Complete the following tasks to perform a VSS-integrated recovery:
Prepare for the recovery as follows:
Identify the snapshot volume associated with each missing production volume. Note the drive letter or mount point of each volume.
Delete the missing volumes from Storage Foundation.
Replace the failed hardware and add the new disks to the dynamic disk group.
Reassign the drive letters or mount points of the snapshot volumes so that they are the same as the missing production volumes.
Use the vxsnap restore command to recover the databases by including the -r switch in the vxsnap restorecommand.
For example, run the following command:
vxsnap -x snapdata.xml -r restore restoreType=PIT writer="Microsoft Exchange Writer"
This command uses the information in the snapdata.xml file to restore all the volumes in the snapshot set identified in that file to the point in time the snapshot set was created or last refreshed.
Refresh the snapshot set.
