Controller
You must enter a value for this option because it identifies the controller that you want to configure:
•
All
—Configure all detected controllers in the system.
•
First
—Configure the first controller found, based on the controller with the lowest PCI slot number.
Internal controllers are used before external controllers.
The
-internal
and
-external
command line switches influence what ACU regards as the
First
controller. For example, if you use the
-external
switch, the
First
controller is the first external
controller discovered, regardless of the number of internal controllers in the host system.
•
Slot [

, or the external controller at port

CacheState
This option enables you to flush the cache or disable flushing of the cache. Values are
FlushEnable
and
FlushDisable
.
You can use this option to prevent stale cache issues.
ClearConfigurationWithDataLoss
Clearing the configuration causes data loss because it deletes all logical volumes and arrays on the
controller. If you clear a configuration, you can write commands later in the script file to create a new
configuration from the liberated drive capacity.
The values for this option are
Yes
or
No
. The default value is
No
.
DriveWriteCache
This option controls the settings of the write cache for all connected physical disks. For this option, the setting
is Enable or Disable. Not all physical disks or controllers support this option.
