Appendix D. Troubleshooting
The first step in problem solving is establishing whether the problem lies with the cartridge, the drive, the host computer and its connections, the backup software or with the way the system is being operated. If none of the following advice helps you solve the problem, contact your supplier.

| |
|
|
The computer starts but does not recognize the tape drive
Possible reason | Recommended action |
|
|
The power or SCSI cable is not connected properly. | Check that the cables to the tape drive are firmly |
| connected. Ensure that the SCSI cable is |
| and that it does not have any bent pins. Replace if |
| necessary. |
|
|
The SCSI bus is not terminated correctly. | Check that the SCSI bus is actively terminated. (Refer to |
| the documentation for your SCSI controller and any |
| other SCSI devices you have). |
|
|
The SCSI ID address of the tape drive is not unique. | Make sure that each device connected to the SCSI |
| controller has a unique SCSI ID. Remember that 7 is |
| normally reserved for the host bus adapter. |
|
|
The application does not recognize the tape drive
Possible reason | Recommended action |
|
|
The application does not support the tape drive. | Refer to your manufacturer’s World Wide Web site for |
| details of backup applications that support the Ultrium |
| tape drive. Load any service packs as necessary. |
|
|
Some applications require drivers to be loaded. | Check that the correct SCSI and tape drive drivers are |
| installed. Consult the installation notes of the backup |
| application for details. |
