Action
CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the
components inside the system. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the computer and protecting against electrostatic
discharge.
NOTICE: This troubleshooting procedure can destroy data stored on the hard drive. Before you proceed, back up
all files on the hard drive.
1
Run the appropriate online diagnostics test. See "Using Server Administrator Diagnostics" on page 131.
Depending on the results of the diagnostics test, proceed as needed through the following steps.
2
Remove the bezel. See "Removing the Front Bezel" on page 53.
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 a 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: Do not perform the following step if you have a SAS RAID controller daughter card.
7
If you have the non-RAID SAS controller daughter card, 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 57.
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 147.
If the hard drive functioned properly in another bay but does not function in the original bay, the SAS
backplane has a defective connector.
See "Getting Help" on page 147.
8
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.
