Chapter 9: Using the CFGGEN IR Configuration Utility
• Text surrounded by <> must be replaced with a required parameter.
• Text surrounded by [ ] may be replaced by an optional parameter.
• Parameters surrounded by {} must be entered one or more times, as is appropriate
for the command being executed.
• The command line definition characters <>, [ ], and {} must not be entered on the
command line.
Common Command Line Parameters
This section describes CFGGEN command line parameters that are common to more
than one command.
•<controller #> – The unique controller number of a PCI function found in the
system, starting with controller # 0. For example, in a system containing two
SAS1068 controllers, controller # 0 references the first controller and controller # 1
references the other controller.
Valid controller number values are 0 to 255 (decimal).
•<SCSI ID> – The SCSI bus address of a peripheral device attached to an SAS
controller. The valid SCSI ID values for supported SAS controllers are 0 to 127
(decimal) per controller.
•<Enclosure:Bay> – The Enclosure and bay/slot of a peripheral device attached to
the bus. The argument must use a colon (:) as a separator and must follow the
enclosure:bay format. This argument is only valid when used with the bay command
line argument. Valid numbers are 0 to 127 (decimal).
CREATE Command
The CREATE command creates IM, IME, and IS volumes on supported SAS controllers.
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 is unusable.
The disk identified by the first SCSI ID on the command line is assigned as the primary
disk drive when an IM volume is created. If the controller is allowed to resync the disk
drives, the data on the primary disk drive will be available when you access the newly
created volume.
NOTE: With PBSRAM, the SAS1068/1068E controllers can support more than
128 devices.
