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 Ready.
Perform the following procedure to assign a dedicated hot spare disk:
1. Enter the BIOS Configuration utility. See Entering the BIOS Configuration Utility on page 20.
2. In the Main Menu screen, select the Manage Hot Spare and press <Enter>.
3. Select Assign Dedicated Hot Spare(s). Press <Enter>.

on the disk drives populated across any slots in the system.
