How to unlock locked root account in HP-UX

By default HP-UX disables the root account if there is repeated number of failed (bad password) attempts. If you root account has been disabled because of bad password there are two options you two ways you can unlock the account without rebooting the server.

1.If you have sudo installed and your account is setup with root privileges then you can login as sudo su and then you can unlock the account using modprpw

$/usr/local/bin/sudo su –

##/usr/lbin/modprpw –l –k root


2.If you don't have sudo setup then other way out is to check on GSP console if you already have root logged in then you can re-enable root account from GSP console
