ABasic Information Logs
Whenever any system or application actions occur, the SuperLoader or 
tape drive generates logs recording the action. You can use some of these 
logs to troubleshoot errors. These logs are described in chapter 5, 
Troubleshooting. The other logs contain diagnostic and history 
information and are explained in this appendix.
This appendix describes the logs for the SuperLoader and tape drives. It 
contains a description of each log type including the log’s block 
descriptor and field descriptions.
Log Descriptions 1 The SuperLoader and tape drive generate different types of logs. 
SuperLoader logs provide information if the error relates to data 
cartridge movement. Tape drive logs provide information on the tape 
drive’s read/write performance. For more information on the different 
types of logs, see the following sections:
• SuperLoader Logs
• Tape Drive Logs on page 238
Although there are several types of logs, all of them have the same basic 
format and are interpreted in same manner. For information on 
interpreting logs, see Before Contacting Quantum Support
