A.3.2 CREATE Command
The CREATE command creates IM, IME, and IS volumes on supported
LSI SAS controllers.
When a disk drive is added to an IM, IME, or IS volume, its entire storage
capacity may or may not be used, depending on drive capacity and
volume capacity. For example, if you add a 36-GB disk drive to a volume
that only uses 9-GB of capacity on each disk drive, the remaining 27-GB
of capacity on the disk drive is unusable.
The disk identified by the first SCSI ID on the command line is assigned
as the primary disk drive when an IM volume is created. If the controller
is allowed to resync the disk drives, the data on the primary disk drive
will be available when you access the newly created volume.
The following rules must be observed when creating IM, IME, and IS
volumes and hot spare disks:
1. All disks that are part of a volume, including global hot spares, must
be on the same SAS controller.
2. A maximum of two IM, IME, or IS volumes per controller can be
created.
3. The total number of disks in a volume cannot exceed ten, and the
total number of disks combined for two volumes cannot exceed
twelve. In addition, one or two hot spare disks can be created per
controller to support IM and IME volumes, for a maximum of 14
supported disks per SAS controller. (Support for this number of disks
requires Integrated RAID firmware v1.20.00 or above.)
4. An IM volume must have exactly two disks.
5. An IME volume can have a minimum of three disks and a maximum
of ten disks, as long as rule 3 is not violated.
