Configuring the RAID160 SA Controller

saconfig Configuration CLI

Chapter 5

The device file for the RAID160 SA controller in the example above is /dev/ciss6.

Displaying the RAID160 SA Configuration

To display the physical disks connected to a RAID160 SA controller, as well as any logical drives and spare

drives that have been configured, issue the saconfig <dev_file> command, where <dev_file> represents

the device file for the RAID160 SA controller.

The channel, SCSI ID, size, and status of each physical disk attached to the RAID160 SA controller is

included in the saconfig <dev_file> output. If any logical drives have been configured on the RAID160 SA

controller, a detailed description of each logical drive that has been configured will also be displayed:

# saconfig /dev/ciss6

******************** RAID160 Controller /dev/ciss6 ********************

---------- PHYSICAL DRIVES ----------

Ch ID Size Status

1 0 18.2 GB UNASSIGNED

1 1 18.2 GB UNASSIGNED

1 2 18.2 GB UNASSIGNED

1 3 18.2 GB UNASSIGNED

In the example above, there are 4 physical disks attached to the RAID160 SA controller (/dev/ciss6). No

logical drive has been configured.

Adding a Spare Disk Drive

The saconfig /dev/cissX -A <Logical drive #> -s <Channel:Target> command is used to add a spare

physical disk to an existing logical drive:

# saconfig /dev/ciss7 -A 0 -s 1:3

Spare drive 1:3 added to Logical drive 0

You can add multiple spare physical disks to a logical drive, depending on the number of physical disks in the

array that are not in use.

Deleting a Spare Disk Drive

The saconfig /dev/cissX -D <Logical Drive #> -s <Channel:Target> command is used to delete a

spare physical disk from an existing logical drive:

# saconfig /dev/ciss7 -D 0 -s 1:3

Spare drive 1:3 deleted from Logical drive 0

You can delete all the spare drives of logical drive 0 at once with the following command

# saconfig /dev/ciss7 -D 0 -s all

All spare drives are deleted from logical drive 0

Change the Rebuild Priority of a Logical Drive

The saconfig /dev/cissX -r <low | medium | high> command is used to set the rebuild priority of

logical dries unders cissx controller
