My SunFire V210 has been having a problem to boot up appropriately.
Therefore, I tried to get to the OBP prompt and hopefully I can boot it
up as single-user mode to see what happened to this system.

Here is what I have tried:

1) from the SC console, type poweroff and poweron and then type reset.
Then I type console. When I am seeing the OS is being boot up, I
issued the Ctrl+Break to try to go to the OBP. Looks like the system
got the signal, but unable to break. Here is what I see from the
console --> SC Alert: SC Request to send Break to host.
SC Request to send Break to host.

2) to start up the system in a normal way, i.e. poweron the system,
wait to see the system is being boot up. This time, I type break from
the SC prompt. Same thing. --> Are you sure you want to send a break
to the system [y/n]? y
sc>
SC Alert: SC Request to send Break to host.


My question is:

How do I make this V210 to release it's OBP? so that I can type "boot
-s" on it.

Please advise, thanks!
Cathy

I'm not familiar with the SC console but while the machine is up you can
type reboot -- -s to reboot to single user mode.

The system can never boot to the login prompt. I always hangs in the
middle during boot up. That's why I cannot type reboot.

From the sc> prompt, try

This is a more 'aggressive' style break generating an XIR (externally
initiated reset).

The most aggressive solution if you pull out the root disk and try to
boot up without it.

When you are at OBP disable auto-boot and power-off the system. Put
back the disk back and power on again.

Do you have the DVDROM drive option? ... boot cdrom -s
