fsck on 11.00

[james gould]

Replaced a tape drive that was told to me by HP was
a hot swap tape drive. HP stated you could replace
the tape while users were on as long as nothing else was
on the bus. Well this did work for about 2 days then the
system crashed. The inittab became corrupt so I put in
another and was able to reboot the server.
The system seems to be slow at times and disk I/0 and
cpu are pretty high at times.

Was wondering if and fsck should be done? Hopefully it does
not take too long with Advanced JFS. - Thanks

Without a crash dump analysis, it is not possible to determine the reason for the crash. fsck is run automatically when the system reboots and fixes directory structures. It will never fix corrupted data files or bad spots on the disk. Without a lot more details, it would be impossible to determine the reason for the slowdown.

Hi James,

it might be just a coincedence that the box crashed. As Bill already said, you need to have a look at the crash dump.

Here are a few things you can check for a possible answer:

1) check etc/shutdownlog
2) /var/adm/syslog/OLDsyslog.log
3) see if you have a crash dump in /var/adm/crash with the correct timestamp.
Usually you find an INDEX file there and you might see a string for panic ... in there.

You can check this site for help on q4 for analysing the dump

if you see HPMC somewhere it probably points to hardware problem.

Hope that helps a bit,
