Program Return Value - 0x00 SUCCESS: command completed successfully. 0x01 FAILURE: command failed. A.3.10 AUTO Command (EFI Version Only) The AUTO command, which is currently supported only in the EFI version of CFGGEN, automatically creates an IM, IME, or IS volume. The volume is 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 the AUTO command you do not specify SCSI ID values for disks to use in the volume. CFGGEN automatically creates the volume with the first usable disks it finds. Firmware and hardware limitations for the family of controllers limit the number of configurations that are possible. 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 are unusable. 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 will be available by accessing the newly created volume. CFGGEN follows these rules when creating IM, IME, and IS volumes and hot spare disks with the AUTO command: 1. All disks that are part of a volume and the hot spares for a volume must be connected to the same controller. 2. IM, IME, and IS volumes are supported. 3. One or two volumes can be created on a single SAS controller. 4. SAS and SATA drives cannot be mixed in a volume. With the AUTO command, all drives used must be the same type as the first available disk found. 5. An IM volume must have exactly two disks.

A.3.10 AUTO Command (EFI Version Only)
The AUTO command, which is currently supported only in the EFI
version of CFGGEN, automatically creates an IM, IME, or IS volume. The
volume is 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 the AUTO command you do not specify SCSI ID
values for disks to use in the volume. CFGGEN automatically creates the
volume with the first usable disks it finds. Firmware and hardware
limitations for the family of controllers limit the number of configurations
that are possible.
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 are unusable.
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 will be available by accessing
the newly created volume.
CFGGEN follows these rules when creating IM, IME, and IS volumes and
hot spare disks with the AUTO command:
1.
All disks that are part of a volume and the hot spares for a volume
must be connected to the same controller.
2.
IM, IME, and IS volumes are supported.
3.
One or two volumes can be created on a single SAS controller.
4.
SAS and SATA drives cannot be mixed in a volume. With the AUTO
command, all drives used must be the same type as the first
available disk found.
5.
An IM volume must have exactly two disks.
