Replacing, moving, or adding hard drives

Recognizing hard drive failure

CAUTION:
be operational after the system is power-cycled or (for a hot-pluggable drive) after the drive
has been removed and reinserted. However, continued use of such marginal drives may
eventually result in data loss. Replace the marginal drive as soon as possible.
The HP Smart Array B110i SATA RAID Controller supports drive LED illumination only on systems with
backplane support for drive LEDs.
The following items indicate a hard drive failure:
•
The following messages appear in ORCA:
1784: Drive Array Failure
o
This indicates a drive failure in a logical volume.
1784: Drive Array Logical Drive Failure
o
This indicates that the entire logical volume has failed. This may mean that multiple drives have
failed.
•
The following POST messages appear when the system is restarted, as long as the controller detects
at least one functional drive:
1784: Drive Array Failure
o
1786: Drive Array Recovery Needed
o
•
ACU represents failed drives with a distinctive icon.
•
HP Systems Insight Manager (SIM) can detect failed drives remotely across a network. For more
information about HP SIM, see the documentation on the Management CD.
•
The HP System Management Homepage (SMHP) indicates that a drive has failed.
•
In Windows operating systems, the Event Notification Service posts an event to the Microsoft®
Windows® system event log and the IML.
•
In Linux operating systems, systems events are logged to /var/log/messages.

Troubleshooting Guide on the HP website (http://www.hp.com/go/bizsupport).

Effects of a hard drive failure

When a hard drive fails, all logical drives that are in the same array are affected. Each logical drive in
an array might be using a different fault-tolerance method. Therefore, each logical drive can be affected
