Before setting cache parameters for a specific array, use the
container list command to obtain information about any
existing arrays.
As the following example shows, there is an array 0 (a volume set)
on this controller with no file system on it (as evidenced by None
displayed in the Usage column):
AAC0>container list

Result
NVRAM write-back cache
The
setting for the specified array is
disabled.
Not allowed. An appropriate error
message displays.
NVRAM write-back cache
The
setting for the specified array is
enabled when protected. This
means the controller enables the
NVRAM write-back
array's
cache
only if a battery is present
and its status is OK.
NVRAM write-back cache
The
setting for the specified array is
enabled always. This means the
controller forces the enabling of
NVRAM write-back
the array's
cache
even if write data could be
lost due to no battery or a bad
battery.
