Specify NOCACHE_UPS to instruct the controller to perform regular
cache battery checks and evaluate the condition of the cache batteries.

Setting the CACHE_UPS switch for either controller sets the
CACHE_UPS switch for both controllers.

COMMAND_CONSOLE_LUN

Enable or disables the virtual LUN used with the StorageWorks
Command Console. When changed, the new setting for this switch
takes effect immediately.

Note This switch enables (COMMAND_CONSOLE_LUN) and
disables (NOCOMMAND_CONSOLE_LUN) the CCL in SCSI-2
mode only. This switch has no effect in SCSI-3 mode.

Enables the mirrored-write-back-data cache feature on dual-redundant
controllers. When changed, both controllers restart for the new switch
setting to take effect.

The following tasks are performed when the NOMIRRORED_CACHE
switch is specified: Both controllers must be operational before this
command is accepted.

non-mirrored mode.

If an invalid cache configuration exists within the cache modules,
an error is generated.
