Wrench Sun V445 hangs before {0} ok prompt

I am having a problem when booting my Sun V445 machine with Solaris 10 installed on it. Machine hangs at boot at following step :

0>Copyright 2007 Sun Microsystems, Inc. All rights reserved
0>OBP->POST Call with %o0=00000800.01014000.
0>Diag level set to MAX.

0>POST: Return to OBP.
SC Alert: Host System has Reset
Configuring system memory & CPU(s)

I am just stuck here, have tried to break and enter into "ok Prompt" for new installation but unable to get there as well. Thanks in advance though.

The main part of the output that you posted is from the system controller (a Linux based appliance that underlies and controls the SPARC machine). The boot up from the SC that you posted finds no hardware errors and says "POST Passed all devices".

My thoughts are that:

1. It could still be a hardware fault but I think that unlikely given the "POST Passed all devices" message.
2. The "Host System has reset" message indicates the start of the SPARC boot process but it's possible that shortly after that console output is switched elsewhere due to a configuration setting on the ALOM.

Suggest that you check that out first and post back any progress or lack of.

How do you access the console output? You might have a "lock" on the console from another terminal... If you are on the ALOM try to start the console with console -f and hit enter after the output stops.

I do not agree with hicksd8 that the output you see is (mainly) from the ALOM... So if you connecting to the console over serial port, you might want to try the ALOM and vice versa.

@DukeNuke2......What do you mean by "try the ALOM"? Enter "#." and see if it drops to the ALOM?

The OP says that he's tried to "break" but it doesn't work.

if he is connecting to the console via serial line or via ALOM and the input-/output-device in OBP is pointing to the wrong device, he might see output but can not generate input...
