Hi,
If you don't have a password for the root/any user, then you need to boot into single user to reset root's password. Then you can bring it up into multiuser and setup any accounts that you require.
To boot into single user, power cycle your machine and
when prompted to interrupt the boot process
You have to:
1) stop the booting
2) On the Main Menu boot from the primary boot:
bo pri
3) When the system ask you: Interact with IPL you must type Y
4) at the prompt of IPL you have to type:
hpux -is
5) When the machine comes up, change the root passwd
passwd /
6) Take into multiuser
init runlevel (where runlevel is the initdefault in /etc/inittab, usually 3)
or
6) Reboot and let it come back up into multiuser, so that you can login
shutdown -r 0
Hope this helps
