Root Lost Password : HP-UX... ;)

... but... what if your system is trusted mode???
..you can use some steps of this procedure if you want re-stablish a password than can not be set by cyclic problems...

The steps to reactivate the root account:
1. Boot the system in to single user mode.
2. Mount /usr file systems.# mount /usr
Note: The file system might need file system check (fsck) before mounting.
3. Systems that are not using Trusted System security skip to step #4.For Trusted Systems (presence of a /tcb directory), follow these additionalsteps:
a) Use the following command to reactivate the 'root' account:# /usr/lbin/modprpw -k root
b) Use the 'modprpw' command to null the password, so that the passwd commanddoes not prompt for the old password.
10.x# /usr/lbin/modprpw -w "" root
11.x# /usr/sam/lbin/usermod.sam -F -p "" root
NOTE: To untrust the system, use: tsconvert -r
4. Change the root account password.# passwd root
5. Boot the system in to multi user mode.

fyi la....
