Advanced commands

Controller=ALL
You can use Controller=All instead of the Slot=N command.
Advantages

You do not need to determine where controllers are installed.

You can target all controllers at once.
Examples
Change read cache to 100% on all controllers (only configured controllers, those with volumes, accept this
command):
Controller=ALL
ReadCache=100
Clear the configuration on all controllers:
Controller=ALL
ClearConfigurationWithDataLoss=Yes
Controller=First
You can use Controller=First instead of the Slot=N command.
Advantages

You do not need to determine where controllers are installed.

You can target the first controller found, a common practice with embedded controllers, because they
are always slot 0. (Controllers are sorted by slot number, lowest to highest, and internal controllers
before external ones.)
Example
Configure a volume on the embedded controller (or the controller in the lowest slot number, if an embedded
controller does not exist):
Controller=First
Array=A Drive=1E:1:1, 1E:1:2
LogicalDrive=1 RAID=1
-internal or -external
You can use the command line option -internal or -external instead of the default option, which is both
internal and external controllers.
Advantage
This option filters the discovered controllers, restricting the command to only internal or only external
controllers.
Example
When using the Controller=First command, if the system had no internal controllers (due to hardware failure
or discovery failure) but had an external controller for shared storage, the script would attempt to create a
volume on the external controller. To prevent that action, the -internal command line argument restricts
discovery to only internal controllers:
# ssascripting -i input.txt –internal
