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>
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 that identify the disk drive that
becomes the hot spare.
Operation
The number of disks in an IM array plus the hot spare cannot exceed three. You can create only
one hot spare disk. Make sure the capacity of the hot spare disk is greater than or equal to the
capacity of the smallest disk in the logical drive. An easy way to verify this is to use the
display
command.
Specifying SCSI Parameters
The following SCSI parameters may be configured for the SCSI board:
•
SCSI ID (SCSI initiator ID)
•
Maximum data transfer rate (SCSI rate)
•
Bus width
•
Whether the HBA is bootable (driver support)
•
Avoid bus resets (secondary cluster server)
NOTE:
Your output might differ from the output in the following examples depending on your
server and its configuration.
