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.
