Replacing a Mirrored Volume
After configuring the above setup, you notice that Disk 4 in your JBOD has
gone offline. Simulate this by removing a physical disk from the JBOD case.
You must replace the disk with a new one and reconstruct the volume
hierarchy built with the simple volume on Disk 4. Your mirrored volume,
Mirror2; created from simple volumes 3 and 4 on disks 3 and 4 respectively,
will continue to operate while your physical disk is down and you replace
one of its simple volumes.
This example explains how to:
 Identify a failed disk.
 Replace a failed disk.
 Synchronize a volume to an existing mirrored volume.
 Remove a failed volume from the V-Switch database.
 Remove a failed disk from the V-Switch database.
