[cisco-voip] Upgraded Partition Backout

[Ryan Ratliff]

There should never be a circumstance where between the time you run  
the upgrade and the manual switch version that the inactive (ie evil  
upgrade) partition takes over.  Even a reboot will keep it on the  
same version until you explicitly tell it to switch versions.   If  
the evil partition does manage to take control you just switch  
versions back to the now inactive partition (the non-evil one).

This is before I switch over to the upgraded version. The scenario I  
am being asked to address is:

Upgrade inactive partition > Do not reboot.

In between the time that I upgraded the inactive partition and the  
scheduled switch over to complete the upgrade the evil inactive  
partition takes over the system and refuses to allow the telephones  
to work. I need to answer how to vanquish this fiend from the system.

On CUCM 6.1.x is there any method to back out an upgrade to an
inactive partition? I have done this type of upgrade at least half a
dozen times with never a problem but I am being asked from a change
management perspective. My original answer of contacting TAC is not
working for me.

Thanks
Steve
