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.
/write_cache_enable{=boolean}
Specifies whether to enable the array's NVRAM write-back
cache.

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
Num Total Oth Stripe
Dr Label Type Size Ctr Size
-- ----- ------ ------ --- ------ ------- ------ -------------
0 Volume 15.0MB
The following example sets cache parameters for array 0 by
accepting all of the defaults:
AAC0>container set cache 0
