NAF-1201 is a weird number we have on the chassis - it's a FAS2220. Password reset is in the boot menu - option 3:
(1) Normal Boot.
(2) Boot without /etc/rc.
(3) Change password.
(4) Clean configuration and initialize all disks.
(5) Maintenance mode boot.
(6) Update flash from backup config.
(7) Install new software first.
(8) Reboot node.
But it sounds like you might have hit the LOADER - if the system is sitting at the LOADER A> (or B) prompt, type "boot_ontap", then when it gives an option to press Control-C, do so and you will get the above menu which will let you reset the password.
If there system is sitting at the LOADER prompt, there are a couple of reasons why:
If the power has just been turned on, if AUTOBOOT (printenv AUTOBOOT) is off/false, it will wait at the LOADER prompt until the "boot_ontap" command is issued, otherwise it will boot ONTAP automatically
If there is a problem booting ONTAP automatically, it will return to the LOADER prompt
If the system has been halt'ed from inside ONTAP, it will wait at the LOADER prompt until the "boot_ontap" command is issued
