Deleting target devices

Syntax:

<target> delete [forced]

where <target> can be a controller, array, or logical drive. Except in the case of controllers, you can delete several devices simultaneously if they are of similar type by using the all keyword.

Because deleting a target device can result in data loss, the screen displays a warning prompt unless you include the forced parameter.

Example commands:

=> ctrl ch="Lab 4" delete forced => ctrl slot=3 ld all delete

Identifying devices

You can enter a command that causes the LEDs on target devices to blink, enabling you to identify the devices. The LEDs continue to blink until you enter the command to stop them blinking.

Syntax:

<target> modify led=onoff

Example commands:

=> ctrl ch="Lab 4" modify led=on

=> ctrl ch="Lab 4" modify array A led=off

Expanding an array

You can increase the storage space on an array by adding physical drives. The restrictions are that the added drives must be of the same type (for example, parallel SCSI or SATA), and they must each have a capacity no less than that of the existing drives in the array.

IMPORTANT: An array expansion, logical drive extension, or logical drive migration takes about 15 minutes per gigabyte, or considerably longer if the controller does not have a battery-backed cache. While this process is occurring, no other expansion, extension, or migration can occur simultaneously on the same controller.

Syntax:

<target> add drives=#:#,#:#,...allunassigned [forced]

where <target> is an array (or a logical drive, if the array contains only one logical drive).

If you add an odd number of drives to an array that contains at least one RAID 1+0 logical drive, the CLI displays a prompt that asks if it is acceptable to convert the RAID 1+0 logical drive to RAID 5 (or RAID ADG if the controller supports this RAID level). Adding the forced parameter to the command prevents this prompt from appearing.

Example commands:

=> ctrl slot=3 array A add drives=1:0,1:1 => ctrl slot=4 ld 1 add drives=allunassigned

Extending a logical drive

If the operating system supports logical drive extension, you can use any unassigned capacity on an array to enlarge one or more of the logical drives on the array.
