Setting the Cache Flush Limit
Sets the amount of unwritten data to remain in cache after a flush is completed on the
given controller. The cache flush limit sets the level at which the disk array stops flushing
cache contents to the disks. This value is expressed as a percentage of the current cache
flush threshold. The default value for this setting is 100%. The cache flush limit can be set
independently for each controller.
To set cache flush limit, type:
ammgr -L <cntrlrID>:<percent> <ArrayID>
•
percent indicates the percentage of cache memory that remains full when flushing of
cache contents stops. For example, if set to 90%, cache memory will be flushed until 90%
of the cache amount defined by the cache flush threshold remains full.
Command Example
The following example sets the cache flush limit to 100% for controller A on disk array

ammgr -L A:100 0000005EBD20
