Volumes 0 through 3 are carved using the first four sizes, as specified.
Volumes 4, 5, and 6 are the autocarved volumes (1024 GB each). Volume 6 is
the remainder of the carve size.
//localhost> /c2 add type=raid0 disk=0:1:2:4:5:6:

Creating new unit on controller /c2 ... Done. The new unit is /
c2/u0.
Setting default Command Queuing Policy for unit /c2/u0 to [on]
... Done.
Setting write cache=ON for the new unit ... Done.
After the unit creation, a subsequent show command for the unit shows the
volume sizes:
//localhost> /c2/u0 show

/cx rescan [noscan]
The /cx rescan command instructs the controller to rescan all ports or vports,
and phys and reconstitute all units. The controller updates its list of disks, and
attempts to read every Disk Configuration Block (DCB) in order to
reassemble its view of logical units. Any newly found units or drives are
listed.
noscan is used to prevent the operating system from being notified of the unit
discovery. The default is to inform the operating system.
Example:
//localhost> /c1 rescan
Note: If you are adding new drives, add them physically before issuing the rescan
commands. If you want to hot-swap drives without first powering down the system,
use hot-swap bays. This helps prevent system hangs and electrical damage.
