Erasing a physical drive

Syntax:

<target> modify [erase erasepattern=zerorandom_zerorandom_random_zero]

where the target can be any valid physical drive.

To stop an erase process at any time, enter the stoperase command.

Example commands:

=> ctrl slot=3 ld 2 modify erase erasepattern=zero

=> ctrl slot=4 ld all modify erase erasepattern=random_zero => ctrl slot=3 ld 2 modify stoperase

Rescanning the system

A rescan detects devices that have been added to the system since the previous rescan or since the HP SSA CLI was started, whichever is more recent.

Syntax:

Use the word rescan directly at the HP SSA CLI prompt, without any target device or parameters.

Example command: => rescan

Entering or deleting a license key

Some advanced configuration tasks (available only on certain controller models) can be performed only after software is installed on the controller and a license key is registered to activate the software.

Syntax:

<target> add [lk=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx]

where the target is any valid controller. The hyphens are optional.

To delete a license key, use a standard delete command but use the license key (not the controller) as the target:

<target> delete

Example commands:

=> ctrl slot=5 lk=12345-65432-78787-43434-24680 delete => ctrl slot=4 add lk=9876543210222224444466666

Optimizing controller performance for video

On some controller models, you can optimize the controller performance for video.

To use this features on an HP Smart Array G6 or G7 controller, a registered SAAP ("About SAAP" on page 131) license key is required.

Syntax:

<target> modify dpo=enable elevatorsort=disable irp=enable queuedepth=automatic mnpd=60

where the target is any valid controller.

The queuedepth parameter can also have a numerical value from 2 to 32, and the mnpd parameter can have any value from 0 (disabled) to 60.
