[cisco-voip] Just an FYI

[Kent Roberts]

Just through I would share.  For those that don’t know… 

New in CUCM 12.5 su4, a excellent new feature (a stupid one) was added….  If a CUCM node takes an unscheduled power down…it must be rebuilt.  There is no way to remove the ungraceful shutdown alert that becomes present.      Only way to recover is via DRS, so make sure your DRS backups are working.    A snapshot backup will trigger the same event as it wasn’t a clean power down.     If no DRS is available, its a complete removal of the entire node, and rebuild from scratch.

So, once you complete your upgrade, run a full backup.
