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

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.
