From ok prompt, use setenv:
setenv <key> <value>
example: ok setenv boot-device disk0 disk1
From OS, use 'eeprom':
example: # eeprom boot-device="disk0 disk1"
The OBP will attempt to open each device in the list sequentially. If
an open fails, it will try the next.
If the open succeeds but has later problems (like the disk isn't a boot
disk), then I think it will error at that point.
So most complete disk failures will allow the boot to failover.
So hopefully most of the time you're monitoring for failures and you can
correct the issues before the machine needs to reboot anyway.
