you need to be able to check the status of a background

build/verify or clear task and determine when it is complete.

The ACU provides a way to do this. When you use record mode to

record a controller’s configuration and you specify a log file (/L

switch), the ACU writes build/verify and clear status information

about each array in the configuration to the log file. An application

or batch file can then parse the resulting log file to determine

whether an array’s build/verify or clear is complete, in progress (a

percentage of the task completed), or failed.

The following example shows a log file of a recorded configuration

consisting of three arrays:

Reading array information ...Passed

Scanning for Drives ...Passed

Reading cache values...Passed

Array #0 Status : OK

Array #1 Status : BUILD/VERIFY 30%

Array #2 Status : BUILD/VERIFY/CLEAR FAILED

Each status line consists of the prefix Array#<n> Status :, where <n>

is the array ID, followed by the status. The possible status values are

as follows:

■ OK

Indicates a nonredundant array (no build required) or a

redundant array whose build task completed successfully.

■ BUILD/VERIFY <n>%

CLEAR <n>%

Indicates a build/verify (or clear) is currently in progress, where

<n> is the percentage of the operation that is complete. The

percentage is an integer between 0 and 99, inclusive.

■ BUILD/VERIFY/CLEAR FAILED

Indicates a build/verify or clear that did not complete due to a

data error or other unexpected problem.

When a build/verify task runs on a multilevel array, the build/

verify occurs on the child arrays and not on the parent array.

Consequently, the parent task always indicates 0% and the child

task indicates 0% to 100%. When a clear task runs on a multilevel

array, the clearing occurs on the parent array and not on the child
