/cx/ux set cache=on|off [quiet]
This command allows you to turn
on
or
off
the write cache for a specified unit
/cx/ux
. This feature is supported on both 7000/8000 and 9000 models.
By default, cache is
on
.
Write cache includes the disk drive cache and controller cache. Note that for
some configuration types, there is only disk drive cache and no controller
cache (for example, JBOD).
The following table shows the supported RAID types for caching as a
function of controller model and logical unit type. N/A (Not Applicable)
refers to cases where the given logical unit type is not supported on a
particular controller model.
The
quiet
attribute turns off interactive mode.
/cx/ux set ignoreECC=on|off
This feature only applies to 9000 series controllers.
This command allows you to set the ignoreECC policy for a given unit.
When ignoreECC policy is set to
off,
if a rebuild process encounters bad
sectors on the source disk, the rebuild will fail. When ignoreECC is set to
on
,
such errors are ignored, and the rebuild will continue. When you use
ignoreECC, a file system check is recommended following the rebuild, to
insure data integrity.
By default, ignoreECC is
off
.
