Read caching percentage can be 0, 25, 50, 75, or 100.

To enable or disable auto-fail missing disks at boot

saconfig /dev/cissX -F on|off

To identify (light LED) SAS/SATA physical drives

saconfig /dev/cissX -I -p <physical_drive_id>

[-p <physical_drive_id> ... ]

To identify SAS/SATA physical drives constituting a logical drive

saconfig /dev/cissX -I -l <Logical drive #>

To extend the capacity of the specified logical drive up to larger

capacity.

The capacity is in GB.

saconfig /dev/cissX -E <Logical drive #> -c <capacity (GB)>

To expand the specified logical drive and others in an array by

physical drive(s)

saconfig /dev/cissX -E <Logical drive #> -p <physical_drive_id>

[-p <physical_drive_id> ... ]

To perform RAID level [with Stripe size (KB)] migration on the specified

logical drive.

The stripe size is in KB.

saconfig /dev/cissX -M <Logical drive #> -R <RAID level>

[-S <Stripe size (KB)>]

To perform Stripe size migration on the specified logical drive.

The stripe size is in KB.

saconfig /dev/cissX -M <Logical drive #> -S <Stripe size (KB)>

To view the

saconfig

manpage for more information, see saconfig(I).

Before running

saconfig

to configure the storage devices connected to a Smart Array Controller,

you must know the device file name for the Smart Array Controller. See

“Determining the Smart

Array controller device file” (page 38)

Displaying the Smart Array controller configuration

To display the physical disks connected to a Smart Array Controller and configured logical drives

and spare drives, use the

saconfig /dev/ciss

command. Replace

with the device file

number for the Smart Array Controller.

The Connector/Enclosure/Bay, WWID, size, and status of each physical disk attached to the Smart

Array Controller is included in the

saconfig /dev/ciss

output. If logical drives are

configured on the Smart Array Controller, a detailed description of those drives appears:

saconfig /dev/ciss5
