If the publisher fails over to the standby then the original PUB come sback on line we DO NOT move the PUB functionality back automatically. Thus you don't want the VIP to move back to that box as its not in 'charge' of the DB so you don't want to fire say Guest creation or Onboard request to that node.

So what you say is that Don't create stand by publisher just VIP and leave every one for his role right?

No, I'm not saying that.

 

I'm saying that the reason we don' move the VIP back the Publisher that failed when it comes back online is that we don't regress the standby-PUB (whch is now the active PUB) back to a standby-state and move the PUB functionality back to the origianl PUB. 

 

The node that was the standy is now the active PUB and stays the active-PUB, it owns the cluster and the VIP.

 

The failed-PUB that has come back online may think it the PUB but it does not own the cluster and you have have made chanegs to the rest of the cluster and you want the SUB's and your NAS devices to talk to the ACTIVE PUB which owns the VIP.

 

Confusing I know....!!!

 

Happy to discuss on a phone call.
