Troubleshooting a SCSI Tape Drive
A SCSI tape drive can be an internal device installed in the externally accessible drive bay or an external device that attaches to a SCSI host adapter
connector on the back panel of the system. The SCSI tape drive is controlled by a SCSI host adapter card installed in the system, which may also control other
SCSI devices connected to one or more SCSI cables. SCSI devices often require device drivers for the particular operating system being used by the system.
Tape drive problems often result from a defective tape drive, a defective tape cartridge, or software. To troubleshoot a SCSI tape drive, perform the following
steps:
1.
Remove the tape that was in use when the problem occurred, and replace it with a tape that you know is not defective.
Is the problem resolved?
Yes. The original tape was defective. Replace it with a new tape. You have fixed the problem.
No. Go to step 2.
2.
Reboot the system and press <F2> to enter the System Setup program.
Is Secondary SCSI set to Enabled?
Yes. Go to step 4.
No. Go to step 3.
3.
Verify that any required SCSI device drivers are installed on the hard-disk drive and are configured correctly. See "Installing and Configuring SCSI
Drivers" in the User's Guide for instructions on installing and configuring the SCSI device drivers for the system's integrated SCSI host adapter or Dell
PowerEdge™ Expandable RAID Controller (PERC) SCSI host adapter card. For any other type of SCSI host adapter card, see the documentation that
accompanied the SCSI host adapter card.
Is the problem resolved?
Yes. The SCSI device drivers were installed or configured incorrectly or were corrupted. You have fixed the problem.
No. Go to step 4.
4.
Reinstall the tape backup software as instructed in the tape-backup software documentation.
Is the problem resolved?
Yes. The tape backup software was corrupted. You have fixed the problem.
No. Go to step 5.
5.
Reboot the system and check for the presence of the tape drive during the ROM scan sequence.
Is the tape drive detected?
Yes. The drive is correctly cabled and is receiving power. Go to step 10.
No. Go to step 6.
6.
Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.

").
8.
Check the SCSI cable connections to the tape drive and to the SCSI host adapter connector. If the tape drive is an internal device, check the DC power
cable connection to the tape drive.
Are the cables firmly connected?
Yes. Go to step 10.
No. Go to step 9.
9.
Reseat the cable connectors and close the system doors. Reconnect the system to the electrical outlet and turn it on.
