Dell R805 owner manual Troubleshooting Your System

3If you are experiencing problems with multiple hard drives, skip to step 8. For a problem with a single hard drive, continue to the next step.

4Turn off your system, reseat the hard drive, and restart the system.

5If your system has the optional battery-cached SAS RAID controller daughter card, perform the following steps.

aRestart 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 controller daughter card are installed and are configured correctly. See the operating system documentation for more information.

NOTICE: Skip the following step if your hard drives are in a RAID configuration.

7For non-RAID configurations only, remove the hard drive and swap its drive bay location with another hard drive that is functioning properly.

If the problem is resolved, reinstall the hard drive in the original bay. See "Installing a Hot-Plug Hard Drive" on page 74.

If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Replace the hard-drive carrier. See "Getting Help" on page 175.

If the hard drive functioned properly in another bay but does not function in the original bay, the SAS/SATA backplane has a defective connector. See "Getting Help" on page 175.

8Check 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 71.

c Verify that the cable connections between SAS/SATA backplane(s) and the SAS daughter card are correct. See "Installing a SAS Controller Daughter Card" on page 84.
