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.
