SUMMARY: Lost all access to my server

Ok. So I finally got this going, thanks for the many responses out of which
I think Glen Carver's and Casper Dick's solutions looked promising. Finally
it was Glen's solution that worked for me. Casper's solution  was a little
too cryptic to execute with my novice experience. Nevertheless in the
process of trying his solution, I learnt how to reset the server using the
ELOM CLI which was what finally made Glen's solution work for me.

Here's what Glen suggested:

Get to the Service processor Command and:

SP> cd /SP/AgentInfo
SP> set ConsoleMux=system
SP> start console

However for me, it did not work at first. I guess my console was already
jammed with output going to ttya. Then after I learnt how to reset the
server while tackling Casper's solution below, I decided to try the above
steps again. This time with a reset like below

SP> cd /SP/AgentInfo
SP> set ConsoleMux=system
SP> cd /SP/SystemInfo/CtrlInfo
SP> set PowerCtrl=reset (this will reboot the server but not the SP)
SP> cd /SP/AgentInfo
SP> start console

Once I got my host console back I could log in and the first thing I did was
to

# eeprom console=ttyb

Then I followed Sun's document about about getting a serial console over LAN
under:
http://docs.sun.com/source/819-6588-13/intro.html#0_62503

I followed this document to the word and now all is fine.

Once again, thanks for all your responses.
Cheers,
Sonam
