The procedure is risky and may damage the system from a software standpoint. It should be done by an expert. In the worst case you will need to re-install the OS and relad your backup tapes.

Sign on as an ordinary user and type "sync". Syncer should be runining anyway, so this may not help much, but it's easy to do and it might help. Wait about one minute or so.

Turn off the system.

Turn it back on.

Interupt the boot process and boot into single user mode. The exact details of this vary from model to model. But basicly you boot from the primary path. And you want to interact with ISL. Once you have that ISL prompt, type "hpux -is".

This should bring the box to single user mode. If the rough shutdown damaged the filesystem too much, you may be in trouble. This is where a lot of expertise comes in handy....

Run "fsck -y" and hope that it can fix the filesystems. This can take a while.

Now run the passwd command or edit /etc/passwd. You may need to mount /usr and /var depending on how your disk is configured and what commands you use.

Unmount anything you mounted.
reboot.

This almost always works. HP-UX is rather robust. But you might want to contact the ex-employee to get the password. After all, he or she will need a good reference, so you should be able to get it.

Read these man pages...

man pdc
man isl
man hpux

pwd

PWD(1)							    BSD General Commands Manual 						    PWD(1)

NAME

     pwd -- return working directory name

SYNOPSIS

     pwd [-L | -P]

DESCRIPTION

     The pwd utility writes the absolute pathname of the current working directory to the standard output.

     Some shells may provide a builtin pwd command which is similar or identical to this utility.  Consult the builtin(1) manual page.

     The options are as follows:

     -L      Display the logical current working directory.

     -P      Display the physical current working directory (all symbolic links resolved).

     If no options are specified, the -L option is assumed.

ENVIRONMENT

     Environment variables used by pwd:

     PWD  Logical current working directory.

EXIT STATUS

     The pwd utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     builtin(1), cd(1), csh(1), sh(1), getcwd(3)

STANDARDS

     The pwd utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

BUGS

     In csh(1) the command dirs is always faster because it is built into that shell.  However, it can give a different answer in the rare case
     that the current directory or a containing directory was moved after the shell descended into it.

     The -L option does not work unless the PWD environment variable is exported by the shell.
