If you have a solaris global zone running fine, but the box crashes.  What steps V440, would you take to check to see if any hardware failures, and then bring it online?

If you have a solaris global zone running fine, but the box crashes.  What steps V440, would you take to check to see if any hardware failures, and then bring it online?

Is there anything you can run at the management port?

If it looks clean, what do you do to bring it up?  If it says you cant get to a root file system, what do you do?
