Procedures for Recovering from a System Panic

Step 1: The Panic Message
In a log book, record and categorize the panic message displayed on the sys-
tem console. The panic message will tell you why the operating system pan-
icked. Sometimes panic messages refer to internal structures of HP-UX (or
its file systems) and the cause might not be obvious. Generally, the problem
is in one of the following categories, and wording of the message should
allow you to classify it into one of them:
