Recovering From a System Crash

To minimize data loss from a system crash, back up your system daily and
verify the backups. Often a graceful recovery from a crash depends upon
good backups.

Your system may have crashed if it fails to boot or respond normally to input
devices such as the keyboard. The most common form of system crash is
terminal lockup—your system fails to accept any commands from the
keyboard. Sometimes when a system crashes, data is damaged or lost.

Note:

Before going through a crash recovery process, check your terminal

configuration and cable connections. If everything is in order, try accessing
the system through the system console (if present) or remotely from another
terminal.

If none of the solutions in the previous paragraphs is successful, you can fix
most problems that occur when a system crashes by using the methods
described in the following paragraphs. You can prevent additional problems
by recovering your system properly after a crash.

The following list presents several ways to recover your system from a crash.
The simplest method, rebooting the system, is presented first. If that fails, go
