Cannot connect to Starfire domain via netcon.

Check netcon_server process on ssp

you found: netcon_server -r

This should not be happening under normal conditions. Before netcon_server
starts, there is a cb_reset and they check if the domains are up. For some
reason, the ssp got the wrong info about the domain and assumed that domains
are not up and, therefore, did not start netcon_server with -p.  So, there must
have been some other event occouring in the system that we do not know of,
perhaps another cb_reset that disallowed the domain info to pass through. 

In any case the solution is:

killing netcon -r then starting the netcon_server with -p option and 
specifying the domain boot processor that is listed in:
/$SSPVAR/etc/<platname>/domain_name>/bootproc file

ssp% netcon_server -p <boot processor number>

After this, check if process running. You should be able to connect to 
domain.

There should be one netcon_server running for each domain with the respective 
boot processors.

For more information read netcon_server man page.
