Solution  1017475.1 :   Sun Enterprise[TM] 10000: netcon fails to get connected.

Symptoms
Sometimes when attempting to start a netcon session to a Starfire[TM]
domain, you just get a "trying to connect" message without seeing
"connected." even if you wait several minutes.

Example:
starfire-ssp:Starfire1% netcon
trying to connect...

You may find that you can telnet to the domain ok, that the OS is working
without problems, and that the cvcd is running.

Resolution

If this is the case, then the most common cause is that the netcon_server
process for that domain which runs on the SSP has died.
netcon_server is started by bringup and should remain running as long as
there is either an OBP or an OS on the domain. During an SSP reboot it is
automatically restarted by startup.tcl, but other than that it is not
monitored by the startup.tcl script.
If you want to be sure which netcon_server process relates to which domain
(there should only be one per domain), you can use the following
command:
/usr/ucb/ps -axwwe | grep netcon_server | grep -v grep
{ NOTE: The output of this command is extremely verbose, as you get about
16 lines per process, and you can't reliably use grep to shorten it further! }
Check the value of SUNW_HOSTNAME which is displayed for each
netcon_server process.
To restart the netcon_server for a domain, use:
domain_switch <domainname>
netcon_server -r
This is the same way startup.tcl *reconnects* to netcon_server to the
domai

Comment: Reviewed comments about possible duplication. Checked 70018 and it refers to cases where netcon does connect but doesn't display a prompt. Although the cause of that may be also be the netcon server dying, the error in this case is different.

Added trademarks, minor formatting and grammatical changes. Ready to publish.
