Solaris U10 - Crash OS
Hello,
I an triyng to write an emergency procedure, and I need your help, or point of view.
I trying to find a way to get connected to an U10 Sun Solaris by the serial port to be able to get access to the system to debug systeme crash before restarting the server.
The SUN U10 does not have MGT or NET admin port. So mouse and keyboard are linked to the avocent, but this useless in case of a system crash.
I did try 10 times to get connected to the system by the serial port using Putty or Hyper terminal, but all failed.... Only once, when I rebooted the serveur with the serial port connected.
If anyone may share his experience or help.
It may be impossible to make it work, but if anyone knows how to do, I will be pleased to read it ... ; )
Thanks

My question is how can I tell if a zone crashs or shuts down... (4 Replies)
