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):

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.
