2 If you are experiencing problems with multiple hard drives, skip to step 6.
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 Verify that the controller is enabled and the drives appear in the System
Setup program. See "Using the System Setup Program" on page 31.
6 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 47.
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 64.
d Verify that the SAS or SATA cables are securely seated in their
connectors.
e Close the system. See "Closing the System" on page 47.
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 137.
