Smart Array 5i Controller - Administrator Password

[Paul Smith_17]

Have a Smart Array 5i controller in a DL380 and required to reconfigure the array configuarion. On powering up the server press F8 at the appropriate time to re-configure. Pops up a blue screen prompting for a "administrative password security" have tried HPINVENT and admin and last 6 digis of s/v backwards stil no access any of my companies standard passwords.
How can I reset this password or remove it. Not sure why it is there, unaware of setting this up.
