Basic information logs

Whenever any system or application actions occur, the autoloader or tape drive generate logs recording the actions. You can use some of these logs to troubleshoot errors. These logs are described in Chapter 5 “Troubleshooting your Autoloader”. The other logs contain diagnostic and history information and are explained in this section.

This section describes the logs for the autoloader and the tape drive. It contains a description of each log type including the log's block descriptor and field descriptions.

Log descriptions

The autoloader and tape drive generate different types of logs. Autoloader logs provide information if the error relates to data cartridge movement. Tape drive logs provide information on the tape drive's read/write performance.

Although there are several types of logs, all of them have the same basic format and are interpreted in the same manner.

Autoloader logs

The autoloader generates four types of logs.

You can retrieve and view each of the six log types through different methods.
