Hello MQ Cluster forum users,

Is it supported to have cluster MQ nodes virtualized (VMs) in a Microsoft (MSCS) HA failover cluster?

What's an "MQ node"? MQ only has queue managers. Sometimes they participate in an MQ cluster. Sometimes they don't.

So the question becomes "is an MQ queue manager supported in an MSCS cluster" and the answer is yes.

This is a Microsoft OS question. Have you tried it? what was the result?

I refer also to your own post here where one of the links you include is to the MQ Knowledge Center page describing MQ's support for MSCS.

Which is strong evidence it's supported.

The same page also explicitly answers your question in a section helpfully titled "Relationship of HA clusters to queue manager clusters". If MQ clusters are not supported under MSCS, IBM would not have described the relationship between them.

I know that MQ supports MSCS.
I am just asking especially about Virtualized implementation of MSCS (Queue Managers in VMs) since, the IBM's MQ position for Virtualization article, posted at:
https://www.ibm.com/support/pages/ibm-mqs-support-position-virtualization-low-level-hardware-file-systems-networks-and-high-availability
mentions:
"Unless stated otherwise, IBM MQ has not been specifically tested in Virtualization environments. IBM MQ Support is therefore unable to assist in issues related to configuration and setup, or issues that are directly related to the Virtualization environment itself.."
Has anybody tried this?

P.S.
Cluster is a collection of nodes. Node is representation of MQ server in a graph.

So which virtualized implementation are you using? You talk about VMs, which is often short hand for the VMWare software, which is one of the specifically tested configurations.

Are you expecting IBM to issue a blanket statement of support for all present and future virtual implementations? Especially the OEM, non-IBM implementations?

Of course not, but as you might know MSCS HA is one of the most commonly used cluster deployment scenarios, worldwide.

Your OP seems to be more about IBMs support of MSCS and MQ in a 3rd party container. Which container? Docker? Chef? Some other?

There is no container in place.

Actually my main concern if cust. will be entitled for defect support, in case of MQ failure whether Queue Managers are deployed in Virtual Machines (VMs) either on Active/Passive or Active/Active MSCS cluster mode.

What your customer will get from IBM in any given circumstance is a question for your customer's account rep. Trying to raise a PMR "because a group of anonymous, unaccountable strangers on the Internet said this was supported" will be a challenge.

(Raising a PMR for supported configurations isn't exactly straightforward either but that's a different conversation)

Turning to your specific issues, VMWare is one of the virtualization technologies IBM tests with. Have they tested the combination of MQ & ESX versions you're using? I don't know and am too lazy to investigate. It's a character failing I've learned to live with.

I do know that VMWare is supported with MQ 8 & 9 because we use it, but we use it with RHEL not Windows so that's of very little help to you.

It's not a good day here.

MQSC HA clusters can work with physical Windows Servers or Windows VMs. We choose physical for MSCS clusters because it is more reliable than VMs, and reliability is a very importance aspect of HA. MQ works OK in either physical or VM.

Your question should really be directed at your IBM account representative, or a in an IBM Service Request. Don't trust us on such important matters.

Thanks for the tips.
I will contact local IBM account rep and perhaps I create a service request.
