Diagnostics and Troubleshooting
This chapter describes the procedures for diagnosing platform problems and drive errors
which can cause the DLT MiniLibrary to malfunction. It also provides Fault Symptom
Codes and Error Recovery Procedures to help restore operability.
5.1 Diagnosing Problems
There are two main types of problems that can cause the DLT MiniLibrary to
malfunction or fail to perform correctly: platform problems and general drive
errors. Some errors cause Fault Symptom Codes (FSC) to be displayed on the
control panel, along with a description of the fault. Error Recovery Procedures
(ERP) are available for each FSC. They are described in this chapter.
5.1.1 Platform Problems:
These errors arise out of incorrect installation and configuration. The most
common characteristic of this type of error is that the drive appears to operate
normally, except that no data can be interchanged. You may not get an error code
on the control panel. To identify an error as this type of problem, check your
installation and configuration setup, referring back to
Chapter 4 - Configuration
and
Appendix B - Installation
5.1.2 General Drive Errors
These errors usually result from a miscommunication between the drive
processors or involve a mechanical malfunction. In most cases, these types of
errors report an error message and an FSC to the control panel. The only
exceptions are power supply problems and display malfunctions. The FSC can be
used to determine a recovery procedure.
Some error messages can be cleared by pressing the
ENTER
button on the
control panel, others by cycling the power to the library. Often the module will
resume normal operation. Other errors are repeated when the operation is
attempted again. Such recurrent errors may require more extensive recovery
procedures such as replacement of a part.
