Troubleshooting SCSI Hard Drives



Troubleshooting a SCSI Hard Drive (System With a SCSI Backplane)



Problem

l Device driver error.

l Hard drive not recognized by the system.



Action



1. Run the appropriate online diagnostic test. See "Using Server Administrator Diagnostics" in "Running System Diagnostics."

For information about testing the controller, see the SCSI or RAID documentation.

If the tests fail, continue to the next step.



2. If the integrated SCSI host adapter controls the SCSI hard drives, restart the system and press <Ctrl><a> to enter the SCSI configuration utility

program.



3. Ensure that the primary SCSI channel is enabled, and restart the system.



4. Verify that the device drivers are installed and configured correctly. See the operating system documentation.



5. Remove the hard drive and install it in another drive bay.



6. If the problem is resolved, reinstall the hard drive in the original bay. See "Installing a SCSI Hard Drive" in "Installing Drives."

If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Replace the drive carrier. See "Installing a SCSI

Hard Drive" in "Installing Drives."

If the problem persists, the SCSI backplane board has a defective connector. See "Getting Help."



7. Check the SCSI 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."

c. Verify that the SCSI cable is securely connected to the SCSI host adapter.

The SCSI cable may be connected to the SCSI host adapter on the system board or to a SCSI host adapter card installed in an expansion slot.

d. Close the system. See "Closing the System."



8. Format and partition the hard drive. See the operating system documentation.



9. If possible, restore the files to the drive.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See

your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against

electrostatic discharge.

NOTICE: This procedure can destroy data stored on the hard drive. Before you continue, back up all files on the hard drive.

NOTE: If your system has an optional RAID controller card installed, restart the system and press <Ctrl><a> or <Ctrl><m>, depending on the

utility. See the documentation supplied with the controller for information about the configuration utility.
