| 3. If the workstation does not display the SCSI devices under the Fibre |
| Channel HBA in the control panel, restart the workstation and then |
| recheck for the appearance of the library SCSI devices. |
| 4. (If DLT) Run the tape diagnostic utility from the NT workstation to |
| verify that the library and drives are detected and pass all |
|
|
NOTE | (If DLT) If the tape diagnostic utility has not been installed, install this |
| software from the DIAG subdirectory on the User Guide |
| 5. Verify SCSI Bus Configuration: Check all appropriate devices for the |
| |
| following conditions: |
| • Termination: Problems with termination can cause intermittent or |
| hard failure. Two connectors are implemented for each SCSI bus, |
| supporting middle of bus configurations. |
| Terminate the SCSI bus on both ends, and only at the ends of the |
| bus. Check each terminator and connector for bent pins. |
| • Bus Type: |
| differential devices on the same bus. Similarly, differential |
| terminators cannot be used on the |
| • Device ID: Each device on a SCSI bus must have a unique ID. The |
| default SCSI ID of the Fibre Bridge is 7. Make sure that this ID is |
| not in use on the bus. Check the library user guide for the default |
| SCSI IDs. Verify that other IDs on the bus are not in conflict. |
| • Cabling: Check SCSI cables to verify that they are functional, then |
| perform the following procedures: |
| a. Be sure the maximum cable length on the |
| cable connected to the Fibre Bridge does not exceed a total of 3 |
| meters. |
| b. Check all cable connections and pins on the connectors. Reseat |
| the connections if necessary. |
