enter

It sounds like you have messed with root's shell. You CANNOT have any other shell for root except /sbin/sh. The reason is that the sbin directory contains the commands which do not require /usr (and the /usr/lib directory) to be available.

To get out of your current mess, use this command:

mount /usr
/sbin/mv /wrong/dld.sl /usr/bin

Then you should be able to reboot. The next step is to change root's shell to /sbin/sh and then to immediately change root's password and never give it to the DBA again. Most likely, the DBA is trying to 'fix' HP-UX to match some other system like Linux -- a plan that will destroy your system.

Remember when using the mv command, used the full path /sbin/mv. The cp command is not here.
(I'm pretty sure I got this right, others can correct me easily enough.)
When you run cp, it is trying to use that dld.sl program. Since the dld.sl file is moved, it won't find it. So it bombs out.
bdf? yep. same thing.

I actually had a similar problem once after a disaster. My solution was to boot up into maintenance mode via an ignite tape shell. Then I ran:
/sbin/mount /dev/vg00/lv??? /usr
mv /usr/bin/dld.sl.mistake /usr/bin/dld.sl
Then I rebooted.

If you're lucky, you will not need to boot from ignite.
