Drive Test Failures

Disk Drive 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 6(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 5and 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:

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

•Display/operation panel shows an )as status for the drive that has failed

•Audible alarm sounds (if enabled)
