Read this url, it will tell you how to use Serial Console.
http://www.idevelopment.info/dat ... erialConsoles.shtml
Creating dump file:
1. Make sure you dump device has enough space and set up correctly.
#dumpadm
2. Flush data from system buffers to disk
#sync
3. Force kernel to save a live dump file
#savecore -L

Dump files normally are saved under /var/crash/savecore_directory.
I don't know how to read dump files, regularly we send dump files to Oracle/SUN for root cause analysis.

We got server hang issue back a while ago, after long time of troubleshooting, it turns out the server load was too heavy. It run out of thread.

Peter,Thanks for your warmly help. l left for days.
After i read the article of you provide, I still doubt that if l can't connect server from local, can i connect  the server with Serial Console when it is hanged?
