The ALOM is very useful for remotely managing your Solaris server. You should always have it configured and accessible via serial console or network, in the event that you have an unresponsive box that needs a kick. Here are a few useful commands I have found over the years for manipulating the ALOM.
Change the ALOM password from the OS
cd /usr/platform/`uname -i`/sbin ./scadm userpassword admin
Reset the ALOM to Factory Defaults
1. Power the machine down with an 'init 5'. Remove power cords for several seconds.
2. Press 'esc' key during ALOM boot when this is on screen:
Boot Sector FLASH CRC Test Boot Sector FLASH CRC Test, PASSED. Return to Boot Monitor for Handshake
After 'esc' key is pressed you get the ALOM Menu
3. Enter e to erase the ALOM NVRAM
4. Enter r to return to ALOM boot process
