hi,

i do not think u need to boot to single user mode to unlock root.

# /usr/lbin/modprpw -k root
would have done that.

boot to single user mode, if you have totally forgotten your root password.

regards.

Hi,


All you have to do is reboot the machine and go into single user mod and change the password. That's all


Thanks & Regards

Try to reactivate account via SAM (or use /usr/lbin/modprpw -k root)

Also check for -t lockfiles under /tcb
# find /tcb -name \*-t
If lockfiles are found rename or delete the file(s) and see if this resolves your problem.

You could also perform the following to uncovert your trusted system, change the password, then convert your system back to a trusted system:
1) Boot to single user mode
2) # mount -a
3) # /usr/lbin/tsconvert -r (this will revert your system to a non-trusted system)
4) # vi /etc/passwd (remove root's encrypted password)
5) # passwd (set a new password for root)
6) # /usr/lbin/tsconvert (return to trusted system).

[Dani Seely]

You could also try the following, if nothing else works, this should:
1) Boot to single-user mode or reboot the system
2) Interrupt the boot process when you see the prompt, "Press any key to stop in 10 seconds"
3) Boot from the boot device and answer 'Y' to interact from IPL or type: 'bo pri ISL'
4) You will be at an 'ISL>' prompt and you will need to type: 'hpux -is'
5) The system will be booted into single-user mode and you will be logged in as "root".
6) Change the root password using the 'passwd' command and reboot.

Good luck!

Hi,
Are you prompted for password when you try to get into single user mode ?
If yes then only you have the option of booting from the supportCD and run rescue system and mount the / and /usr filesystem on temporary directories and revert back the changes you have made.

at single user mode, only / and /stand are mounted, try this to mount /usr

# /sbin/mount /dev/vg00/lvol7 /usr
# /usr/sbin/passwd
change your password

and then either restart the server or use init 3, but i go for a normal restart.

Hi,
Go to /etc/fstab, look which lvol is for what filesystem. Then mount the filesystem /usr and /var.

#mount /dev/vg00/lvolx /usr
#mount /dev/vg00/lvolx /var
#passwd
New Password:
Confirm Password:

This should work,.
All the best.

in secure system
i can't mount /dev/vg00/lvol7 /usr

[Joseph Loo]

sorry, that is only an example.

check /etc/fstab:

# /sbin/cat /etc/fstab
look for which logical volume is /usr mounted to:
# /sbin/mount /usr
and do the necessary changes.

regards.

[Bharat Katkar]

Hi there,
1. Boot to the single user mode using "hpux -is" at ISL prompt.
2. You will the hash prompt directly.
3. cat /etc/fstab, look for line containing /usr and see which logical volume it is using.
4. Let us consider it as /dev/lvol6 (whatever you have)
5. mount /dev/lvol6 /usr
6./usr/lbin/modprpw -k root
7.reboot

See if that works.

All the best.
