Action
1. Remove the hard disk drive that was being tested when the server stopped
responding and try the diagnostic test again.
2. If the hard disk drive diagnostic test runs successfully, replace the drive that
you removed with a new one.

program.
Action

v All cables and cords are connected securely to the rear of the server and
attached devices.

in each SAS chain is terminated correctly.
If the problem remains, call for service.
