Assign and Unassign Dedicated Hot Spare
Does my controller support this feature? See Supported Features.
A dedicated hot spare is an unused backup disk that is assigned to a single virtual disk. When a physical disk in the virtual disk fails, the hot spare is activated
to replace the failed physical disk without interrupting the system or requiring your intervention.
For more information on hot spares including size requirements, see Protecting Your Virtual Disk with a Hot Spare. For considerations regarding RAID 10 and
RAID 50 virtual disks created using the controller BIOS, see Dedicated Hot Spare Considerations.
To assign a dedicated hot spare:
1. Select the disk in the Connector (channel or port) table that you want to use as the dedicated hot spare. On some controllers, more than one disk can
be selected. The disks you have selected as dedicated hot spares are displayed in the Disks currently configured as dedicated hot spare table.
2. Click Apply Changes when ready.
To unassign a dedicated hot spare:
1. Click the disk in the Disks currently configured as dedicated hot spare table to unassign it. On some controllers, more than one disk can be selected.
Clicking the disk removes the disk from the Disks currently configured as dedicated hot spare table and returns it to the Connector (channel or port)
table.
2. Click Apply Changes when ready.
NOTE: The Unmirror task is not supported on the CERC SATA1.5/2s controller.
NOTE: On the CERC SATA1.5/6ch controllers, doing an Unmirror on a RAID 1-concatenated virtual disk results in a concatenated virtual disk that cannot
be subjected to any further modification. You cannot reconfigure or add disks to the resulting concatenated virtual disk. If you do an Unmirror on a RAID
1 virtual disk, the resulting concatenated virtual disk can be reconfigured back to a RAID 1 virtual disk. After you have reconfigured to a RAID 1 virtual
disk, further reconfiguration may be possible.
NOTE: This operation is not supported when using a dynamic virtual disk with a CERC SATA1.5/6ch controller.
NOTE: On Linux, an Unmirror cannot be performed on a mounted virtual disk.
CAUTION: Your virtual disk is longer redundant.
NOTE: The CERC SATA1.5/2s controller does not support dedicated hot spares.
NOTE: For PERC H700 and PERC H800 controllers, if any of the drives you selected is in the spun down state, the following message is displayed: The
below listed physical drive(s) are in the spun down state. Executing this task on these drive(s) takes additional time, because the drive(s) need to spun
up. The message displays the ID(s) of the spun down drive(s).
