CREATE Command
The CREATE command creates IM volumes on the SAS controller. Firmware and hardware
limitations for this family of cards limit the number of configurations that are possible.
Syntax
cfggen <controller #> create <volume type> <size> [qsync] [noprompt]
Parameters
<volume type> Volume type for the volume to be created. Valid value is IM.
<size> Size of the IM volume in megabytes, or “MAX” for the maximum size
available.
[qsync] Quick synchronization of the volume created.
[noprompt] Eliminates warnings and prompts.
Operation
After a disk is added to an IM volume, its storage capacity might or might not be used depending
on drive capacity and volume capacity. For example, if you add a 36 GB disk to a volume that
only uses 9 GB of capacity on each disk, the remaining 27 GB of capacity on the disk is unusable.
The disk identified by the first SCSI ID on the command line is assigned as the primary disk when
creating an IM volume. If the SAS controller is allowed to resynchronize the disks, the data on the
primary disk is available by accessing the newly created volume.
AUTO Command
The AUTO command automatically creates an IM volume on the SAS controllers. The volume is
created with the maximum number of disks available for use in the specified volume type. The
main difference between the AUTO command and the CREATE command is that with AUTO
command, you do not specify SCSI ID values for disks to use in the volume. The cfggen utility
uses the first disks it finds that are usable in the IM volume. Firmware and hardware limitations for
the family of controllers limit the number of configurations that are possible.
Syntax
cfggen <controller #> auto <volume type> <size> [qsync] [noprompt]
Parameters
<volume type> Volume type for the volume to be created. Valid value is IM.
<size> Size of the RAID volume in megabytes, or “MAX” for the maximum size
available.
[qsync] Quick synchronization of the volume created.
[noprompt] Eliminates warnings and prompts.
Operation
When AUTO creates an IM volume, the first disk found is assigned as the primary disk. If the
controller is allowed to resynchronize the disks, the data on the primary disk is available by
accessing the newly created volume. Reply Yes if you want to complete the creation.
HOTSPARE Command
The HOTSPARE command creates a hot spare disk. The hot spare disk is added to hot spare pool
0.
Syntax
cfggen <controller #> HOTSPARE [DELETE] <Encl:Bay>
