A disk must conform to certain criteria to be used as a hot spare for a particular data disk.
For a disk to be used as a hot spare for another disk, it must conform to the following criteria:
- It must be either an exact match for the disk it is replacing or an appropriate alternative.
- If SyncMirror is in use, the spare must be in the same pool as the disk it is replacing.
- The spare must be owned by the same system as the disk it is replacing.
