[cisco-voip] CUCM 6.1(2) upgrade

Wed Dec 10 10:05:54 EST 2008

"Back in the days" you restored the broken mirror and were back up instantly.  I did it many times never had a issue.  

Now most enterprise cusotmers do a snapshot and can restore in less than 45 minutes.

 6.1.2 I understand you can "rebuild" the database from CLI without reinstalling the software on all subscribers.

Just my .02

Keep in mind that two years ago this was all windows based.  What was your backout plan if your update failed and corrupted the database.  Most of the time it was a full rebuild of the server somewhere around 4-6 hours.  Then the subscribers.....

What they have given us is far better than anything we had in the windows world. 

With that being said they are starting to do some transferring of settings in CUCM 7.  User facing features do get transferred.  I think it is only a matter of time before when you go to switch versions it does a second snapshot so you don't lose any data.

	Similar to using Norton Ghost to write your active operating system to hidden partition on disk.

	We have a large hospital that buys Dell desktops with 80GB hard drives. They only partition a 40GB hard drive and the other 40GB has a install ghost image.  At boot hit F10 and select restore from ghost and your PC is back at brand new install state.  Reduces support costs for them.

	This shouldn't be a surprise at all.  The 'inactive' partition is exactly that, 'inactive'.  It is a separate partition with a separate OS and separate database.  If the two were reliant on each other, then where would the failback be if a single database went defunct?

	I was just as surprised as you are when I found out.

		Really??  I think this shoots to hell then my plan to download 6.1.2 to the inactive partition and swap partitions at a later date. I thought when it swapped over it would use the data base from the active partition. So it coverts the data base when you load the upgrade on the inactive partition and this upgraded database on the inactive partition is used?

		When you upgrade, you get a snapshot of the database. You'll have to  
		consider a change freeze or log/ duplicate all changes after your  
		reboot. I'm not sure about 6.1 but 7 does have user facing  
		features( like forwarding ) that are preserved.
