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.

Ensure that the required device drivers for your SAS controller card or SAS
RAID controller are installed and are configured correctly. See the

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 54.

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.

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