Appendix D: Using the Array Configuration Utility for DOS ● 100For example:StripeSize=256Type KeywordType is a required keyword, indicating the array type. There is no default value. The possiblevalues: Volume, RAID0, RAID1, RAID5, RAID10, or RAID50.Depending on the RAID levels supported by your RAID controller, additional possible valuesare: RAID1E, RAID5EE, RAID6, RAID60.Wait KeywordWait is an optional keyword that you can use to tell the ACU to allow the ACU to continuewhile the Build/Verify or Clear completes in the background; specify Wait=No. Otherwise, theACU waits by default.If the host is powered off before the Build/Verify or Clear process completes and is thenrestarted, the process resumes without any user intervention.For example:Wait=YesWait=NoWriteCache KeywordThe WriteCache keyword indicates whether write caching is used for this array if write cachingis supported for the system. Possible values are as follows:● Yes (default)—Enable the write cache.● No—Disable the write cache.Setting an array’s WriteCache keyword to Yes might result in data loss or corruption during apower failure.For example:WriteCache=YesACU Error CodesWhen the ACU detects an error, it reports the error and exits immediately. If a log file isspecified, the ACU writes the error code to the log file. Otherwise, it displays the error code onthe screen.The possible error messages returned by the ACU are listed in this table.Code Description0 ACU ran without changes—ACU exited with no errors (success) and no report is required.1 No controller found.2 Syntax or logical error in the script file—The ACU encountered an invalid command orkeyword in the specified script file.3 Unable to open file.4 Error in the command line parameters—You passed an invalid command-line switch to theACU. (See Running the ACU Using Scripts on page 95 for a list of valid command-line switches.)
