260 Virtual Disks
NOTE: On the CERC SATA1.5/6ch controllers, doing a Split Mirror on a RAID 1-
concatenated virtual disk results in concatenated virtual disks that cannot be
subjected to any further modification. You cannot reconfigure or add disks to the
resulting concatenated virtual disks. If you do a Split Mirror on a RAID 1 virtual disk,
the resulting concatenated virtual disks 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. For information on restrictions associated with
concatenated virtual disks on these controllers, see Number of Physical Disks per
Virtual Disk and Exceptions to One Physical Disk Limitation for Concatenated Virtual
Disks on CERC SATA1.5/6ch and CERC SATA1.5/2s Controllers.
NOTE: On the CERC SATA1.5/6ch controllers, this operation is not supported when
using a dynamic virtual disk or for a RAID 1 virtual disk that is in a Failed
Redundancy state.
NOTE: On Linux, a Split Mirror cannot be performed on a mounted virtual disk. For
this reason, a Split Mirror cannot be performed on the boot drive.
To Split a Mirror:
Click Split Mirror. To exit without splitting the mirror, click Go Back To
Virtual Disk Page.
CAUTION: Your virtual disk is longer redundant after performing a Split Mirror
operation.
To locate this task in Storage Management:
1 Expand the Storage tree object to display the controller objects.
2 Expand a controller object.
3 Select the Virtual Disks object.
4 Select Split Mirror from the Available Tasks drop-down menu.
5 Click Execute.
