HP Array Configuration Utility 60
Erasing a physical or logical drive
Syntax:
<target> modify [erase
erasepattern=zero|random_zero|random_random_zero][deleteaftererase=yes|n
o]
where the target can be any valid physical drive or logical drive. The option to delete the target after erasing
it is valid only if the target is a logical 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 ACU CLI
was started, whichever is more recent.
Syntax:
Use the word
rescan
directly at the ACU 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.
For this feature to be available, you must install SAAP on the controller and register the SAAP license key.
Syntax:
<target> modify dpo=enable elevatorsort=disable irp=enable
queuedepth=automatic mnpd=60
where the target is any valid controller.
