Drive Test
Failures
When the Built-In Self-Test (BIST) described previously has finished, a
firmware-based drive test is executed that tests the integrity and functionality
of each drive channel, including the capacity to rebuild and generate parity.
If a drive fails when tested, the drive is first shown on the display as (spinning
up); other drives that pass the drive test are shown as (good). In the following
example, drive 3 is shown failing the drive test.
When the drive test times out, drives that pass the drive test are shown as and
the failed drive is shown as (drive 3 in the example).
Note If multiple drives fail, the array will display a message similar to
this message:
Disk Drive
Failures
The array will continue to function if one disk drive fails.
Caution When a disk fails, it should be replaced and a rebuild should be
performed as soon as possible. See disk replacement and rebuild
instructions later in this chapter.
Indicators

• Audible alarm sounds (if enabled)
