Assign and Unassign Dedicated Hot Spare

Dell OpenManage™ Storage Management User's Guide

A dedicated hot spare is an unused backup disk that is assigned to a single virtual disk. When an array disk in the virtual disk fails, the hot spare is activated to replace the failed array 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 for RAID 10 and RAID 50 on PERC 3/SC, 3/DCL, 3/DC, 3/QC, 4/SC, 4/DC, 4e/DC, 4/Di, 4e/Si, 4e/Di, and CERC ATA100/4ch Controllers.

Note: The PERC 2/SC, 2/DC, and CERC SATA1.5/2s controllers do not support dedicated hot spares.

To assign a dedicated hot spare:

Select the disk in the Channel table that you wish 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.
Click Apply Changes when ready.

To unassign a dedicated hot spare:

Click the disk in the Disks currently configured as dedicated hot spare table to unassign it. Clicking the disk removes the disk from the Disks currently configured as dedicated hot spare table and returns it to the Channel table.
Click Apply Changes when ready.
