3.5 Troubleshooting Your Tape Drive
This section provides both general troubleshooting guidelines and an LED-specific problem/solution
table to help you troubleshoot your tape drive.
3.5.1 General Troubleshooting Guidelines
If you have a problem when using the tape drive, first try to isolate the cause of the problem. For
example, if you have just installed a new SCSI host bus adapter and the system will not start, the cause
of the problem is likely to be the adapter.
When installing multiple items of hardware and software, install each item one at a time, restarting the
system each time. Also, if you have installed multiple devices or software and then experience
problems, remove or uninstall each in turn to establish which one is causing the problem.
Remember that the system recognizes devices during power on. If you swap or connect a product when
the system is running, be sure to restart the system. Restarting the system resets devices and often
resolves problems. It is good practice to restart after adding a driver or installing new firmware.
3.5.2 Troubleshooting the Tape Drive
Table 3-2 on page 3-20 provides troubleshooting information on errors indicated by front panel LEDs,
including the following topics:
• None of the tape drive’s LEDs illuminate.
• All of the LEDs on the front panel blink continually.
• The host server or workstation does not recognize the tape drive.
• There are fatal or non-fatal errors for which you cannot find the cause.
