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 <Ctrl><R> 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.
