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 [

][:

]

—Configure the internal controller in slot number

, or the external controller at port

in slot

•

WWN [

]

—Configure the external controller that has the World Wide Name

•

SerialNumber [

]

—Configure the shared storage controller that has serial number

•

IOCabinet[

],IOBay[

],IOChassis[

],Slot[

],Cabinet[

],Cell[

]

—Configure

the controller in the Integrity server that has the slot path information defined by this sequence of

identifiers.

CacheState

This option enables you to flush the cache or disable flushing of the cache. Values are

FlushEnable

and

FlushDisable
