Sids,
Have you checked if this command is found at bin and sbin directories

$ls -l /usr/bin/ps
$ls -l /usr/sbin/ps

If you can see the file at either one of the locations, then i suggest that you see if these directories are defined in the PATH

Post echo $PATH ...

And try after the following

export PATH=$PATH:/usr/bin:/usr/sbin

If not you can copy it from another node (same version) / recover from backup

Sids,

As Duncan pointed out, you /usr seems to be missing. Check the output of dmesg for errors concerning /usr at boot-up time. We'll need to find the reason it didn't get mounted and fix it so we can mount it.

Sorry, Sids, my old eyes must be playing tricks on me - I could have sworn it wasn't there, but I see it now.

Attaching /usr/bin/ps command.

I think I have an idea if u have a Tape or a Floppy Drive, Looks logical but never tried.

1. Boot the node through the Install CD ==>>Open Recovery Shell ==>

loadfil /usr/bin/ps
loadfil /usr/sbin/insf
loadfil /usr/sbin/tar
loadfil /usr/sbin/ioscan
insf -e
ioscan -fnCtape
tar cvf /dev/rmt/0mn /usr/sbin/ps

Boot the system normally and restore this tape !

Regds,

Sids, there are multiple problems with copying ps this way. But first finding out where ps has gone.

(Next time) take a look in /usr/lost+found for files there. If fsck has found problems on your filesystem and doesn't know where a file belongs, it is put there. So you should check lost+found directories after each reboot to make sure your filesystems are still intact when you miss files.

Next: could it be your reboot was due to a patch installation? Perhaps a patch on ps? In that case, removing that patch would solve the issue.

And that leads to a problem with putting a 'random' ps version on your system. There are patches for commands like ps, so if you want to be sure you install the right ps, you should first check what patches are installed and then copy the command from a environment on the same patch level.

Perhaps creating a recovery tape on regular basis can help too. If you loose something from your vg00, you can recover it from there, or reinstall your system exactly the way it was.

Good luck, and I hope this info is still of some use.
