Troubleshooting Your System
NOTICE:
This troubleshooting procedure can destroy data stored on the hard drive. Before you proceed, back up
all files on the hard drive.
1 Run the appropriate online diagnostics test. See "Using Dell PowerEdge Diagnostics" on page 97.
Depending on the results of the diagnostics test, proceed as needed through the following steps.
2 If you are experiencing problems with multiple hard drives, skip to step 5. For a problem with a single
hard drive, continue to the next step.
3 If your system has a SAS RAID controller, perform the following steps.
a Restart the system and press to enter the host adapter configuration utility program.
See the documentation supplied with the host adapter for information about the configuration
utility.
b Ensure that the hard drive has been configured correctly for the RAID.
c Exit the configuration utility and allow the system to boot to the operating system.
4 Ensure that the required device drivers for your SAS controller card or SAS RAID controller are
installed and are configured correctly. See the operating system documentation for more information.
5 Check the cable connections inside the system:
a Turn off the system, including any attached peripherals, and disconnect the system from the
electrical outlet.
b Open the system. See "Opening the System" on page 41.
c Verify that the cable connections between the hard drive(s) and the drive controller are correct,
whether the connections are to the SATA connectors on the system board, a SAS expansion card,
or a SAS RAID controller. See "Hard Drives" on page 51.
d Verify that the SAS or SATA cables are securely seated in their connectors.
e Close the system. See "Closing the System" on page 41.
f Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.
If the problem persists, see "Getting Help" on page 107.
