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. To disable the video performance optimization feature, reverse the disable and enable values noted above, set the queue depth to automatic, and set mnpd to 0, as in the second example command. Example commands: => ctrl slot=5 modify dpo=enable elevatorsort=disable irp=enable queuedepth=16 mnpd=25 => ctrl slot=3 modify dpo=disable elevatorsort=enable irp=disable queuedepth=automatic mnpd=0 Creating a logical drive Syntax: create type=ld [parameter=value] is usually a controller, but it can be an array if you are creating an additional logical drive on an existing array. If you want to create a logical drive on a group of physical drives that are not yet assigned to an array, you do not have to build the array first. In the CLI, unlike in the GUI, the array is created automatically at the same time as the logical drive.

parameter can also have a numerical value from 2 to 32, and the
mnpd
parameter can

To disable the video performance optimization feature, reverse the disable and enable values noted above,
set the queue depth to automatic, and set
mnpd

Example commands:

Creating a logical drive
Syntax:
<target> create type=ld [parameter=value]
<target>
is usually a controller, but it can be an array if you are creating an additional logical drive on an
existing array.
If you want to create a logical drive on a group of physical drives that are not yet assigned to an array, you
do not have to build the array first. In the CLI, unlike in the GUI, the array is created automatically at the same
time as the logical drive.
The standard parameters used when creating a logical drive are described in the following table. If you do
not specify a particular parameter, the CLI uses the appropriate default value.
