Figure 94. Stripe 1 Volume and Supporting Hierarchy Removed

If you are working in

aV-Switch cluster, the volume must be replaced on both V- Switches.

Replacing a Volume

You can replace a volume with another volume. Use the CLI command volume replace after a disk failure to replace a volume used in a storage hierarchy with a volume on a functional disk. This is only a ‘physical’ replacement. The data on the failed disk is not copied to the new volume.

If you are replacing a volume used as part of a mirrored volume, continue with the CLI command volume mirror synch to synchronize the replacement volume with the other mirrored volume(s). See “Synchronizing a Volume,” page 166.
