If you setthis switch to TRUE, the command enables the read-aheadcache for the specified array. This switch should always beenabled 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 thisswitch 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-backcache.ExamplesBefore setting cache parameters for a specific array, use thecontainer list command to obtain information about anyexisting 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 Nonedisplayed in the Usage column):AAC0>container listExecuting: container listNum Total Oth Stripe Scsi PartitionDr Label Type Size Ctr Size Usage C:ID:L Offset:Size-- ----- ------ ------ --- ------ ------- ------ -------------0 Volume 15.0MB None 0:02:0 64.0KB: 15.0MBThe following example sets cache parameters for array 0 byaccepting all of the defaults:AAC0>container set cache 0
