Troubleshooting an External SCSI Tape Drive
Problem
l Defective tape drive
l Defective tape cartridge
l Software or device driver
l Defective SCSI host adapter
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 drive and are configured correctly.
For instructions on installing and configuring device drivers for the system's integrated SCSI host adapter, see "Using the Dell OpenManage Server
Assistant CD" in the User's Guide.
For a SCSI host adapter card, see the documentation that accompanied the card.

4. 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 and 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 and reinstall the tape drive.
e. Replace the SCSI cable that connects the tape drive to the SCSI host adapter.
f. Reconnect the system to the electrical outlet and turn on the system.
5. If the problem is not resolved, see " Getting Help " for instructions on obtaining technical assistance.
Troubleshooting SCSI Hard Drives
Problem
l The drive itself
l SCSI backplane board
Systems with a ROMB card issue the following signals by using the drive indicator lights:
l If a drive shows signs of imminent failure, the power-on/fault indicator slowly blinks green, amber, and off.
l If a drive has failed, the amber power-on/fault indicator blinks four times per second.
Action
1. Reboot the system and press <Ctrl><a> to enter the SCSI configuration utility program.
CAUTION: This troubleshooting procedure can destroy data stored on the hard drive. Before you proceed, back up all the files on the hard drive.
