How to reset an ILOM password
worked for ILOM 2x (in my case on a 7410 and 7310)
While connected (serial) on power-on, you will see "Booting linux in 3 seconds...", then you will have to enter the "xyzzy" combination and you will be dropped into this small boot manager shell
U-Boot 1.1.4 custom GRASP U-Boot 1.3 (Sep 12 2008 - 13:52:00) r36901 [...] Booting linux in 3 seconds... xyzzy DORADO_ONE>setenv bootretry=-1 DORADO_ONE>setenv preserve_conf no DORADO_ONE>saveenv DORADO_ONE>reset
It's reseted to default, so "changeme" will be the root password again.
