To overide the ALOM password on the Sun Fire (V210, V240, V250 or V440) system you will need to perform the following tasks:

  1. Attach console to Serial Management Port
  2. Power on the server via the front power button. Once POST has completed, you will need to wait 1 to 2 minutes for a timeout to occur and the system to drop to the <ok> prompt. NOTE: If you do not get the "Please login:" prompt (you will likely see the SC prompt) then you must power the system off remove the battery from the LOM board, wait a minute, and re-install everything).

    * Below is an example of what you might see on the console:

    Please login:
SC Alert: Host System has Reset
[wait one two minutes]
Serial line login timeout, returns to console stream.
<ok>

  3. Boot the system to the OS level. If Solaris is not currently installed on the server, you will need to install it at this point.
  4. 4) Use the scadm command to reset the admin password: 
    # cd /usr/platform/`uname -i`/sbin
# ./scadm user/password admin
  5. Use the escape sequence "#." to get system back to the alom login prompt. You can now log into the admin account using the password from step 4 b).
