Smart Array SCSI Diagnosis feature

The HP Insight Diagnostics Online Edition provides the capability to use non-intrusive system level checks to diagnose Smart Array SCSI hard drives. Diagnosis supports SCSI, SATA, and SAS hard drives that are attached to a Smart Array controller and configured as part of a logical volume. Diagnosis is not component testing, but is a combination of drive history and controller error status.

Diagnosis assists in confirming hardware status and is faster than offline testing. Using the diagnosis feature reduces downtime and provides information on one pass.

The diagnosis feature should be used:

• To troubleshoot why a hard drive is in a particular state.
• When HP SIM reports a hard drive pre-failure or that a hard drive has failed.
• When data corruption or storage problems occur, but no physical indications are evident.
• When conflicting errors exist.
• When repeated failures occur.
