Hi Gents,
I am looking for experience help here...
I have two BE6Ks with VMware Hypervisor on top of which CUCM, UCCX, UNITY,EXPRESSWAY are running. Each server is in a different City and have been configured in PUB/SUB and currently fully working.
The problem that I am facing is the C220-M3 model is end of the life; therefore, I am working with Business for replacement.
In the meantime, I need to make sure if hardware failure occurs, business is not impacted or has limited impact at least.
My plan is to do a FULL failover test. That's where I am looking for experience, if you had done this in the past, please advise.
Nonetheless, my plan is to proceed in two stages:
1. Start by shutdown the interface connect to the server. So no network connection and watch if the phones register with the pub will fallback to SUB server. And UCCX calls routing is not interrupted as well.
2. Second full power down the PUB BE6k. Again observe the behavior.
Advice, suggestion are welcome.
Thanks,
