Common Command-Line Parameters
This section describes command-line parameters that are common to more than one
command.
• <controller #>
The unique controller number that the program assigns to each PCI function found
on supported controller chips in the system, starting with controller # 0. For
example, in a system containing two controllers, controller # 0 references the first
controller and controller # 1 references the other controller. Valid controller number
• <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. Enclosure is a 16-bit EnclosureHandle value set by the IOC. A value of 0 is
invalid. Bay/Slot is a 16-bit slot value set by the IOC. Use the DISPLAY command to
get the enclosure and slot numbers of a drive.
CREATE Command
The CREATE command creates Integrated RAID volumes on SAS2 controllers.
When you add a disk to an Integrated RAID volume, some of its storage capacity may
not be used. For example, if you add a 300-GB disk drive to a volume that only uses 200
GB of capacity on each disk drive, the volume does not use the remaining 100 GB of
capacity on the disk drive.
The disk identified by the first Enclosure:Bay on the command line becomes the primary
disk drive when you create an Integrated Mirroring (RAID 1) volume. If the controller
resyncs the disk drives, the data on the primary disk drive becomes available when you
access the newly created volume.
When the IR firmware creates a RAID1 volume, it starts a background initialization of the
volume. You can use the STATUS command to monitor the status of the initialization.
Observe the following rules when creating Integrated RAID volumes and hot spare
disks:
• All disks that are part of a volume, including hot spares for that volume, must be on
the same SAS2 controller.
• You can create RAID0, RAID1, RAID1E, and RAID10 Integrated RAID volumes.
• You can create a maximum of two Integrated RAID volumes per controller.
• The configuration of the Integrated RAID firmware determines the maximum and
minimum number of drives that you can use in Integrated RAID volumes.
The configuration is specified in the following fields of IOC Page 6:
MaxDrivesRAID0, MaxDrivesRAID1, MaxDrivesRAID10, MaxDrivesRAID1E
MinDrivesRAID0, MinDrivesRAID1, MinDrivesRAID10, MinDrivesRAID1E,
MaxVolumes, MaxPhysDisks, MaxGlobalHotSpares, MaxPhysDisks
(maximum
number of physical drives combined in all volumes on the controller)
