Using the AUTO Command The AUTO command automatically creates an IM volume on the SAS controllers. The volume will be created with the maximum number of disks available for use in the specified volume type. The main difference from the CREATE command is that with AUTO command user does not specify SCSI ID values for disks to use in the volume.

Using the AUTO Command
The AUTO command automatically creates an IM volume on the SAS controllers. The volume
will be created with the maximum number of disks available for use in the specified volume
type. The main difference from the CREATE command is that with AUTO command user does
not specify SCSI ID values for disks to use in the volume. The
cfggen
utility automatically 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 Mbytes 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 drive.
If the controller is allowed to resync the disk drives, the data on the primary disk drive is available
by accessing the newly created volume. Reply
Yes
if you want to complete the creation.
HOTSPARE
The HOTSPARE command creates a hot spare disk drive. The hot spare drive will be added to
hot spare pool 0.
Syntax
cfggen <controller #> HOTSPARE [DELETE] <Encl:Bay>
Parameters
<controller #>
A SAS controller number between 0 and 255.
[DELETE]
Specifies that the hot-spare is to be deleted (Omit the DELETE keyword
to specify hot-spare creation).
<Encl>:<Bay>
Enclosure number and Bay number of the disk that is to be configured as
the Hot Spare.
Operation
An IM array can contain a total of three disks, including the hot spare. Only one hot spare disk
can be created. The capacity of the hot spare disk must be greater than or equal to the capacity
of the smallest disk in the logical drive. You can use the
“DISPLAY”
command to verify disk
capacity. For more information on disk requirements, see
“Rules for creating IM volumes and
hot spare disks:” (page 42)
.
DELETE
The DELETE command sets the controller configuration to factory defaults. This command will
also delete any existing IR volumes.
Syntax
cfggen <controller #> delete [noprompt]
