[cisco-voip] CUCM 6.1 Upgrade Recovery Question

[Ryan Ratliff]

You joke but you'd be surprised how many people will just yank a  
drive or two while the server is running and then complain when they  
can't boot off of them.  The fact that even HP doesn't support  
pulling drives as a backup method helps us out in those situations  
but when a few words (obvious as they may seem) can  help avoid a  
potentially big problem it's worth stating the obvious.

haha, I love this advice.  You mean we can't do hot upgrades by  
replacing all the disks at once while the server is up?  That would  
be a great feature.  I'm getting on the phone with my sales engineer  
now.
