156 Troubleshooting Your System
3
If 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.
4
Turn off your system, reseat the hard drive, and restart the system.
5
If your system has the optional battery-cached 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.
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.
6
Ensure 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.
7
For 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

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 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.
