The console command appears to 'hang the machine' as you say because the main chassis is powered off. Only the service processor is running.

At some point you need to give the service processor the command:

Code:
power on

or on other Sparc models:

Code:
poweron

before the main chassis will light up. There's no mystery about that but, right now, I can't figure out what boot stage you are at.

Hi,

OK, there may be no option here but to go for the nuclear option on this, so you can try the following;

Code:
-> stop -force /SYS

Failing that you could try;

Code:
-> stop -force -script /SYS

Please note that this will force a complete stop of the system, then you can run;

Code:
-> start /SYS
-> start /SP/console

Show any output, this should go through the POST for the server so there may be quite a bit of output.

Hi Folks,

I'm maybe being a bit naive here, in assuming the server was powered on I just assumed that the server had been running and wouldn't restart.

If the machine has been forced off from the front panel you will as hicksd8 says have to issue a power on command.

Hi,

You may have to set the "bootfailrecovery" to "Powercycle" and increase the "maxbootfail" from "3".

Also you could go for the simple approach and start the "console" and press the power button on the front panel if you can get to it (It's recessed so you need to use a Biro to reach it).

2- ran the command start /SP/console
3- Clicked on power button after step-2
But no success

Hi,

It might be worth waiting for a while at the end of the sequence in my previous post.

Can you post the output of;
Code:
show /SYS

You could also try a;
Code:
reset /SYS

Lastly you could possibly try;
Code:
-> start -script /SYS

This should force a powercycle if the reset command doesn't work, I'm not sure if the -force switch works with the start and I don't have any boxes that are that old to try it on.
