CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the computer and protecting against electrostatic discharge.

NOTICE: This troubleshooting procedure can destroy data stored on the hard drive. Before you proceed, back up all files on the hard drive.

1Run the appropriate online diagnostics test. See "Using Server Administrator Diagnostics" on page 121. Depending on the results of the diagnostics test, proceed as needed through the following steps.

2Remove the bezel. See "Removing the Bezel" on page 46.

3If you are experiencing problems with multiple hard drives, skip to step 7. For a problem with a single hard drive, continue to the next step.

4Turn off your system, remove and reinstall the hard drive, and restart the system. See "Removing a Hard Drive" on page 59 and "Installing a Hard Drive" on page 61.

5If your system has a SAS RAID controller daughter card, 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.

bEnsure that the hard drive has been configured correctly for the RAID.

cExit the configuration utility and allow the system to boot to the operating system.

6Ensure that the required device drivers for your SAS controller card or SAS RAID controller daughter card are installed and are configured correctly. See the operating system documentation for more information.

7Check 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 48.

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 (see Figure 3-12), a SAS expansion card (see Figure 3-13), or the SAS RAID controller daughter card (see Figure 3-14).
