Appendix B: EEPROM-Resident Bugcheck and Event Logs

B-2 Quantum DLT 4000 Tape System

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.

B.2.1 POST Failure Packets

POST failure packets are stored whenever the Power On Self Test logic detects a

failure of any kind. Each failure is encoded as a 4-byte vector. In some cases,

multiple vectors may be stored.

If logging of POST failures occurs, contact a service representative.
