on to the next method, and so on. Here is an overview of the different crash
recovery methods:
• rebooting the system
Rebooting usually fixes problems associated with a simple system crash.
• restoring system software
If you do not find a simple hardware connection problem and you cannot
reboot the system, a system file might be damaged or missing. In this case,
you need to copy system files from the installation tapes to your hard disk.
Some site-specific information might be lost.
• restoring from backup tapes
If restoring system software fails to recover your system fully, you must
restore from backup tapes. Complete and recent backup tapes contain copies
of important files. Some user- and site-specific information might be lost.
Refer to the IRIX Advanced Site and System Administration Guide for the
instructions used to perform each of the recovery methods listed above.
If your system continues to fail, most likely you have a serious software
problem, and you must restore the system software and files using the
procedures described in the Personal System Administration Guide. If the
system fails to respond at all, call your service organization for assistance.
