Does my controller support this feature? See "Supported Features."
Use the following omconfig command syntax to separate mirrored data originally configured as a RAID 1, RAID 1-concatenated, or RAID 10 virtual disk. Splitting
a RAID 1 or RAID 1-concatenated mirror creates two concatenated nonredundant virtual disks. Splitting a RAID 10 mirror creates two RAID 0 (striped)
nonredundant virtual disks. Data is not lost during this operation. See "Split Mirror" for more information.

Complete Syntax
omconfig storage vdisk action=splitmirror controller=id vdisk=id
where id is the controller ID and virtual disk ID as reported by the omreport command. To obtain these values, you would enter omreport storage controller to
display the controller IDs and then enter omreport storage vdisk controller=ID to display the IDs for the virtual disks attached to the controller.

Example Syntax
For example, to initiate a split mirror on virtual disk 4 on controller 1, you would enter:
omconfig storage vdisk action=splitmirror controller=1 vdisk=4

omconfig Unmirror

Does my controller support this feature? See "Supported Features."
Use the following omconfig command syntax to separate mirrored data and restore one half of the mirror to free space. Unmirroring a RAID 1 or RAID 1-
concatenated virtual disk results in a single, nonredundant concatenated virtual disk. Unmirroring a RAID 10 virtual disk results in a single, nonredundant RAID
0 (striped) virtual disk. Data is not lost during this operation. See "Unmirror" for more information.

Complete Syntax
omconfig storage vdisk action=unmirror controller=id vdisk=id
where id is the controller ID and virtual disk ID as reported by the omreport command. To obtain these values, you would enter omreport storage controller to
display the controller IDs and then enter omreport storage vdisk controller=ID to display the IDs for the virtual disks attached to the controller.

Example Syntax
For example, to unmirror virtual disk 4 on controller 1, you would enter:
omconfig storage vdisk action=unmirror controller=1 vdisk=4

omconfig Assign Dedicated Hot Spare

Does my controller support this feature? See "Supported Features."
Use the following omconfig command syntax to assign one or more physical disks to a virtual disk as a dedicated hot spare.
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."

Complete Syntax
omconfig storage vdisk action=assigndedicatedhotspare controller=id vdisk=id pdisk=<PDISKID> assign=yes
where id is the controller ID and virtual disk ID. The <PDISK> variable specifies the physical disk. See "pdisk=<PDISKID> Parameter" for more information.
To obtain the values for the controller, virtual disk and physical disk, you would enter omreport storage controller to display the controller IDs and then enter
omreport storage vdisk controller=ID and omreport storage pdisk controller=ID to display the IDs for the virtual disks and physical disks attached to the
controller.

NOTE: The CERC SATA1.5/2s controller does not support dedicated hot spares.
