Troubleshooting Hard-Disk Drives

•Tape drive online indicator fails to light after operating system installs

Action

1.Remove the tape that was in use when the problem occurred and replace it with a tape that you know is not defective.

2.Verify that any required SCSI device drivers are installed on the hard-disk drive and are configured correctly.

3.See "Using the Dell OpenManage Server Assistant CD" in the User's Guide for instructions on installing and configuring device drivers for the system's integrated SCSI host adapter or Dell host adapter card.

4.For any other type of SCSI host adapter card, see the documentation that accompanied the SCSI host adapter card.

5.Reinstall the tape backup software as instructed in the tape-backup software documentation.

6.Check the external cable connections to the drive.

a.Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.

b.Check the SCSI cable connection to the host adapter card and the SCSI tape drive. Check the DC power cable connection to the tape drive.

c.Verify that the tape drive is configured for a unique SCSI ID number and that the tape drive is terminated or not terminated as appropriate.

See the documentation for the tape drive for instructions on selecting the SCSI ID and enabling or disabling termination.

d.Reconfigure the tape drive's SCSI ID and termination settings as appropriate. Reinstall the tape drive and reconnect the system to the electrical outlet. Turn on the system.

e.Replace the SCSI cable that connects the tape drive to the SCSI host adapter. Reconnect the system to the electrical outlet and apply power.

7.If the problem is not resolved, see "Getting Help," for instructions on obtaining technical assistance.

Problem

•The drive itself

•SCSI backplane board

•SCSI cable connections to the system board

•Systems using an optional Dell host adapter card issue the following signals by using the drive indicator lights adjacent to each hard-disk drive:

¡Hard drive failure indicator on the control panel lights

¡If a drive shows signs of imminent failure, the drive online indicator stays on and the drive failure indicator blinks on briefly each second.

¡If a drive has failed, the drive online indicator turns off and the drive failure indicator blinks on briefly each second.

Action

CAUTION: This troubleshooting procedure can destroy data stored on the hard-disk drive. Before you proceed, back up all the files on the hard- disk drive.

1.If the integrated SCSI host adapter is being used to control the SCSI backplane board, reboot the system and press <Ctrl><q> to enter the SCSI configuration utility program.

NOTE: If your system has a Dell PERC 3installed, reboot the system and press <Ctrl><h>. See the documentation supplied with the controller for information on the configuration utility.

2.Check that the primary SCSI channel is enabled, and reboot the system.

3.Verify that the device drivers are installed and configured correctly.

See the documentation for the system's operating system.

4.Remove the drive carrier and install it in the another drive bay.

5.If the problem is resolved, the SCSI backplane board has a defective connector. See "Getting Help," for instructions on obtaining technical assistance.
