We have two IPO servers running in a vmware environment - two separate hosts. The primary serves as the license server (webLM), and is the primary voicemail server as well. Note that the only thing running on our VMware hosts are the IPO servers. (probably a waste of resources, but everything else in our environment is on Hyper-V)
I shutdown the second node to upgrade VMware and firmware on the secondary host, and started that second node back up without any significant pain. Some warning messages but no interruption of service.
When I shutdown the primary node to do the same thing on the other host, I'd expected an interruption of service, but not what I experienced.
After shutting the primary node off, All of the expansion systems started lost their ever loving minds because the license server vanished. I'd kind of figured this could happen, but I didn't expect the immediate warnings about a 15 day trial period. Also, while I'd expected an interruption of service, I never expected it would take close to 10 minutes before call's would present more than a single "buzz" and hang up, and that voicemail wouldn't actually work again until the license server was back on-line.
After about 10 minutes I received notifications from all expansion modules that the Voicemail server was back on-line and operational - however no call's would route to voicemail and when I tried calling voicemail I would receive a system alarm e-mail about "The following system resources are all in use: Voicemail Channels".
Rather than troubleshoot these issues, I focused on running the firmware updates, and VMware updates so I could get things back on-line as soon as possible - even thought this was a maintenance window.
What should I have experienced? Should the system fail in this manner if the primary node is off-line?
Is there some way to have a redundant license server for this type of environment?
Can IPO virtual machines be live migrated between hosts without any significant issue to keep this sort of outage from happening?
(We don't currently own vCenter, that could be quickly remedied for this small of a VMware environment)
