Virtual Disks 271
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.
To Unmirror:
Click Unmirror. To exit without unmirroring, click Go Back To Virtual Disk
Page.
CAUTION: Your virtual disk is longer redundant.

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.
