Troubleshooting disk drives and storage systems
To further troubleshoot a disk drive, or if you continue experiencing storage-related issues after running
Diagnose, perform the following tasks:
•
Search for known storage-related issues on the HP we
o search for
customer advisories related to ProLiant servers configured with Smart Array controllers, use the
following search string: +ProLiant +Advisory +"Smart Array".
•
Update the controller driver and firmware revision and any drive-related software components such
as management agents and storage utilities.
•
Reseat physical drives and controllers.
•
Check drive cables for any signs of damage or bent pins.
•
When powering down a system using external storage, power down the server before powering
down the external storage. When powering up the system, power on the external storage before
powering on the server. This action prevents the possibility of drives being failed erroneously by the
controller.
A server power failure before the test, can also cause erroneous failures.
For troubleshooting procedures, see the HP ProLiant Servers Troubleshooting Guide located on the HP
To troubleshoot the backplane, controller, and cables, do the following:
•
Check drive cables for any signs of damage or bent pins.could Try another drive cable from
another server, if possible.
•
If you are able to identify a bad bay, replace the hard drive backplane.
If the backplane and drive cables have already been replaced, the problem may be a bad
controller.
•
Determine if the controller is good by moving it to another server. Boot the server, and watch for any
POST errors. If the controller has already been replaced, the problem is likely to be a bad backplane
or cable.
IMPORTANT:
To minimize downtime, HP recommends that steps involving the reseating of
drives and controllers be performed simultaneously. Perform steps involving multiple drive
reseating, controller reseating, and cable inspection with the server powered off.
