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 follow these additional steps.

  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 
command does not prompt for the old password.

     10.x
     # /usr/lbin/modprpw -w "" root

     11.x
     # /usr/sam/lbin/usermod.sam -F -p "" root

4. Change the root account password.
   # passwd root

5. Boot the system in to multi user mode.
