I agree to what Ralph said.
The HP ITRC is a phantastic forum.
Even if you have an HP software support contract
you often get quicker responses from fellow sysadmins whose main platform
is HP-UX, most of the times containing a solution or hints that at least will
help you further.
But back to your problem.
I am afraid I have no experience with HP workstations.
Btw, have you looked here for a manual of your workstation model?
It should at least drop a line how you can access maintenance mode.

That's where you need to get in order to fix your locked root account.
Btw, a locked root account or lost root password is such a common issue
that I am convinced you will find a thread treating it in the afore mentioned
HP ITRC forum.
The ITRC also has a great knowledge base that you can query with regard
to you problem (but I fear this is only accessible to support contract holders).
If all else fails you should at least be able to boot from a Core OS CD
which starts up an ASCII menu from where you can enter a root shell.
I also don't know the Commercial Security Database.
Somewhere in it must be a field that has a lock set for your root account.
Maybe you had entered too many times a wrong password or similar?
But I am convinced that the lock flag can be removed,
mabe even by moving the whole DB out of place or by providing an interim
empty one.
Please search docs.hp.com for your case.
Most of the HP documents are downloadable.
E.g. here are some manpages that may be relevant to you

If regained access to your workstation and if you have a streamer available
I would strongly advise you to create a disaster recovery tape
by the make_tape_recovery command.
This is part of the freely available Ignite utility.
Search HP site for download and documentation.
Creating an Ignite tape is as easy as issuing one short command.
After successful creation you have a bootable recovery medium
where you either could reinstall the whole OS within half an hour
or where you could access a root shell should your root disks get broken.
