How To Reset The ALOM Password On A Sun Fire T2000

If an ALOM password reset is required on a Sun Fire T1000 or Sun Fire T2000 in case the password is lost or forgotten, the following steps can be taken to erase the ALOM NVRAM so that a user can gain access to it, set a new password and restore the NVRAM settings.

Note: Access to the server’s power cables and the ALOM serial port is required for this procedure.

Connect your computer or laptop to the ALOM serial management port.

Power cycle the system by unplugging the server’s power supplies, waiting several seconds and then plugging the power back in. You should see the ALOM booting on the serial management console. Hit “Esc” during the ALOM boot, before or at the point where the display says:

Return to Boot Monitor for Handshake

The system will return with this message:

Return to Boot Monitor for Handshake ESC keypress detected.

The ALOM enters the “ALOM boot escape menu”. The following choices will be displayed:

ALOM  Menu

e - Erase ALOM NVRAM.

m - Run POST Menu.

R - Reset ALOM.

r - Return to bootmon.

Your selection:

To do an ALOM password reset you must choose ‘e’ to erase the NVRAM. After erasing the NVRAM choose ‘r’ to resume the ALOM boot. You will automatically be logged in as the user ‘admin’ with no password and no permissions. The NVRAM settings will also be reset to factory default. All customizations including the ALOM network settings will be erased and will need to be redefined.
