Parameters

{container}

Specifies the ID number (0 to 63) of the array on which you

want to set cache parameters.

Switches

/read_cache_enable{=boolean}

Specifies whether to enable the read-ahead cache. If you set

this switch to TRUE, the command enables the read-ahead

cache for the specified array. This switch should always be

enabled to optimize performance, unless your application--

which is unlikely--is doing completely random reads.

This switch defaults to TRUE.

To disable the read-ahead cache for the specified array, set this

switch to FALSE. Note that if you disable the read-ahead

cache, no other characteristics can be set.

/unprotected{=boolean}

Specifies whether to set the array’s NVRAM write-back cache

to disable, enable when protected, or enable always. You use

this switch in conjunction with the /write_cache_enable

switch to accomplish the desired setting. See the

write_cache_enable switch for more information.

/write_cache_enable{=boolean}

Specifies whether to set the array’s NVRAM write-back cache

to disable, enable when protected, or enable always. You use

this switch in conjunction with the /unprotected switch to

accomplish the desired setting.
