Appendix B: EEPROM-Resident Bugcheck and Event Logs

B-2 Quantum DLT 8000 Tape System

B.2 Bugcheck Packets

Bugchecks are the result of some firmware-detected errors. For example, a hardware

failure or an internal system consistency failure may cause a bugcheck. These events

cause bugcheck packets to be written to EEPROM.

The most important information within the packet is the error code. The more common

bugcheck codes are listed in Table B—1. A full listing of all possible codes is not

provided: they are typically associated with firmware or product development and are not

expected once the product is released. Analysis of the other information saved within an

EEPROM bugcheck packet requires the in-depth firmware knowledge to interpret and/or

attempt to determine the actual cause.

Table B–1 Bugcheck Packet Error Codes (Bytes 9 – 10)
