Table 5-6. Values for the Write Cache Setting
■ Write Cache Status
This item indicates the current status of the write cache for the
array and, where appropriate, the status of the battery.
Value Meaning
DISABLE
The write cache is disabled for this array
ENABLE ALWAYS
The write cache setting for the specified array
is enabled always. This means the controller
forces the enabling of the array’s write cache
even if write data could be lost due to no
battery or a bad battery.
ENABLE WHEN
PROTECTED
The write cache setting for the specified array
is enabled when protected. This means the
controller enables the array’s write cache only
if a battery is present and its status is OK.
