container Commands
Table 5-5 summarizes the values for the /write_cache_enable
and /unprotected switches:
Examples
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
Executing: container list

Table 5-5. Switch Values and Results
/write_cache_enable
Switch Setting
/unprotected
Switch Setting Result
FALSE FALSE The NVRAM write-back cache
setting for the specified array is
disabled.
FALSE TRUE Not allowed. An appropriate error
message displays.
TRUE FALSE The
NVRAM write-back cache
setting for the specified array is
enabled when protected. This
means the controller enables the
array’s
NVRAM write-back
cache
only if a battery is present
and its status is OK.
TRUE TRUE The NVRAM write-back cache
setting for the specified array is
enabled always. This means the
controller forces the enabling of
the array’s
NVRAM write-back
cache
even if write data could be
lost due to no battery or a bad
battery.
