Dell R300 owner manual Troubleshooting a SAS or SAS RAID Controller

8If you have a non-RAID SAS controller, 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 75.

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 165.

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 165.

9Check 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 and Closing the System" on page 68.

c Verify that the cable connections between the SAS/SATA backplane and the SAS controller are correct. See "Installing the Backplane Board" on page 102.

d Verify that the SAS cables are securely seated in their connectors.

e Verify that the power cable on the SAS/SATA backplane is securely seated in the connector.

f Close the system. See "Opening and Closing the System" on page 68.

g Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.

If the problem persists, see "Getting Help" on page 165.
