Dealing With Problems
Recovering from a System Panic
NOTE: It is important to maintain an up-to-date backup of the files on your system so
that, in the event of a disk head crash or similar situation, you can recover
your data. How frequently you update these backups depends on how much
data you can afford to lose. For detailed information on how to back up data,
see the manual System Administration Tasks.
Should your system panic, it is important to record and categorize the cir-
cumstances associated with the panic. Table 9-2 will help you do so:
Other problems may result from faulty configuration of the Mode Configu-
ration area of the Boot Console Handler. If you have boot problems, check
that the FASTBOOT option is set to “NO”.
Table 9-2 Summary of Possible Causes of Panics Problem Area and Action
Problem Area Action
Hardware • If the failure appears to be associated with a periph-
eral device:
Check the integrity of the cable connections
Ensure that the peripheral is online.
• If the above did not correct the problem, the failure
may be associated with the System Processing Unit.
In this case; call your designated service representa-
tive.
File System • Run the file system checker, fsck, to correct the
problem. Follow the instructions that fsck may give,
and use reboot -n, for HP-UX, for any subsequent
reboots required by fsck. See System Administration
Tasks for detailed HP-UX information.
LAN • Ensure the integrity of all LAN connections, includ-
ing taps in any AUI cable. Check for proper 50 ohm
terminations at both ends of the LAN.
Other • Reboot the system.
