Power-on behaviour
V210s seem to ship from the factory in a state where they always are "off" when power is applied. If you want the V210 to revert to the previous power state (ie start up once power is applied if the power is removed while the system was running):
# /usr/platform/SUNW,Sun-Fire-V210/sbin/scadm set sc_powerstatememory true
