Assigning the dedicated hot spare disks
A dedicated hot spare is a backup physical disk for the redundant virtual disk to which it is assigned. The physical disk that is used as a
dedicated hot spare cannot be a member of an existing virtual disk. When the hot spare is activated, it becomes the receptacle for the data
from the failed physical disk member of the volume, without interrupting the system or requiring your intervention. A dedicated hot spare
can be assigned to any redundant virtual disk, and up to four hot spares can be assigned to a virtual disk. A dedicated hot spare cannot be
assigned while a task is running on the virtual disk.
NOTE:
A virtual disk is marked Failed or Degraded if a physical disk reports a Failed state, or if the SAS/SATA cable to the
physical disk or power cable is disconnected.
NOTE:
If a virtual disk with an assigned dedicated hot spare is deleted, the dedicated hot spare is also deleted and the physical
disk state changes to the Ready state.
