[cisco-voip] Just an FYI

[russon81]

I've already rebuilt 3 clusters because of this.  Thanks Cisco!

As far as I know, the COP file doesn’t fix anything.  It just removes the warning.  TAC can still see an ungraceful shutdown happened and can still direct you to rebuild.  


And yes. It’s ridiculous that there isn’t a way to do a system check to determine whether or not the system is operating ok.

Intersting that TAC didn’t offer that as a solution nor could they provide any way to validate the box was safe for production.

Yes.  This has been making the rounds in some forums and spaces.  



Great thing is… there’s a COP file to remove the warning from the login screen.




¯\_(ツ)_/¯

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.







Just thought I would share…...
