Chapter 9

Recovering from a System Panic

Most problems are dealt with by implementing some combination of avoidance,

detection, prevention, and recovery. If you are reading this chapter, it is because any

avoidance or prevention measures have failed and a problem has been detected. This

chapter introduces recovery techniques and suggests efforts to minimize the effects

of a panic.

Panics

A panic means that the computer halted because HP-UX was asked to do something

that it did not understand. Panics are rare and are not necessarily catastrophic. The

cause may be due to something like a Local Area Network (LAN) cable being un-

plugged and the solution is to plug it in and reboot your system.

The basic steps to recover from a panic are:

• Write down the panic message

• Categorize the panic type

• Correct the problem
