Disclaimer:Standard: Use the information that follows at your own risk. If you screw up a system, don’t blame it on me...
show-disks
Displays the disks attached to the system and allows you to pick one to be used in a later command.
nvalias [ $device | ^Y ]
Set up an alias for a device. You can use the show-disks command to select a device, then issue a <CTRL>-Y to paste it into the command line. Otherwise, you’re typing the whole device path which is prone to errors.
printenv [ $parm ]
Prints the entire OBP environment unless a parameter is used.
setenv ${parm}
Sets an OBP parameter.
nvstore
Stores all the nvalias parameters that you’ve created.
probe-scsi-all
Displays the h/w path to all devices on the system.
reset-all
Clears out memory - needed before issuing a probe-scsi-all. Ensure the auto-boot? parameter is set to false, otherwise system will competely reboot.
