Solaris ships with a System Controller Administration (scadm) utility. This allows you to manage the alom card from inside the os. Always useful for cards that are stuck or forgotten passwords.

Examples:

# /usr/platform/`uname -i`/sbin/scadm version

# /usr/platform/`uname -i`/sbin/scadm reset -s

# /usr/platform/`uname -i`/sbin/scadm userpassword root
