Using the Array Configuration Utility
Examples:
Wait=Yes
Wait=No
The WaitForBuild Keyword
The
WaitForBuild
keyword is provided for backward
compatibility only. Use the
Wait
keyword instead. The
WaitForBuild
keyword is still recognized and can be used
interchangeably with the
Wait
keyword.
The WriteCache Keyword
The
WriteCache
keyword indicates whether write caching is used
for this array if write caching is supported for the system.
Possible values are as follows:
Yes
—Enable the write cache if the cache is protected by a battery
and the battery’s status is OK.
No
—Disable the write cache.
Always
—Enable the write cache even if no battery is present, or
the battery’s status is not OK.
Note:
Setting an array’s
WriteCache
property to
Always
might result in data loss or corruption if power to the
controller is lost when no battery is present or the battery
loses its charge.
If no
WriteCache
property is specified, the value
Yes
is used.
Examples:
WriteCache=Yes
WriteCache=Always
1
Array build/verifies and clears are tasks executed entirely on the controller
and do not depend on the ACU or any other host application to complete.
If the controller is powered off before the build/verify or clear completes
and is then restarted, the build/verify or clear task resumes without any
user intervention.
