Chapter 9: Using the CFGGEN IR Configuration Utility

The SETOFFLINE command makes a physical disk in a volume offline. A physical disk that is taken offline changes its state to Failed (FLD), but the disk is still associated with the volume and therefore cannot be addressed by normal I/O requests. If a new disk replaces an offline disk, the new disk is automatically brought online. Otherwise, the disk remains offline until explicitly brought online by SETONLINE command.

Command Line –

cfggen <controller #> setoffline <SCSI ID>

Parameters –

<controller #> – Number of the SAS controller targeted by this command.

<SCSI ID> – SCSI target ID of the drive targeted by this command.

Program Return Value –

0x00 SUCCESS: command completed successfully.

0x01 FAILURE: command failed.

SETONLINE Command

NOTE: The SETONLINE command is supported by the DOS, Linux, and WinPE versions of CFGGEN only.

The SETONLINE command brings a physical disk in a volume online. This is required only after the physical disk has been taken offline by the SETOFFLINE command. When a physical disk is brought online, the IOC synchronizes the volume.

Command Line –

cfggen <controller #> setonline <SCSI ID>

Parameters –

<controller #> – Number of the controller targeted by this command.

<SCSI ID> – SCSI target ID of the drive targeted by this command.

Program Return Value –

0x00 SUCCESS: command completed successfully.

0x01 FAILURE: command failed

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.
