GW Monitor mode

RemoteUser — Tue, 01 Apr 2025 16:59:02 GMT

Hello, a customer wants to deploy a cluster node in monitor mode, is it possible to do this? if so, how?

Whilst you have the ability to set an interface as private, sk101670 lists this cluster + monitor mode as not supported.

Hi Chris,

Reading the SK you sent me, I noticed that "Support for Cluster - ClusterXL / 3rd Party cluster is not supported in Monitor Mode." However, we are planning to perform this action on a cluster node...

This makes me think that the node we are going to work on will need to be detached from the cluster. So, should we remove the "unit is a part of cluster" setting, making the other node always active?

This also makes me wonder—will a fresh install be required?

I'm a bit confused about how this should be done. I hope I explained myself clearly.

Thanks!

It's not supported if the gateway is part of a cluster only a discrete gateway or standalone.

Hey @RemoteUser

Chris is correct, it is a limitation for clusterXL.

However, if I want to, can I remove the node from the cluster (standbay one) and use that removed node (GW) to use it as a monitor?

Correct.

Generally, yes, but if you are using an -HA license on the secondary node, you can't do this since an -HA license must be used as a non-primary node for ClusterXL, not on it's own.

I don't think I understand 100%, can you please explain more?

Re: GW Monitor mode

What @PhoneBoy is saying is that if you are using HA license on clustered node and you remove it from the cluster (ie disable cluster mechanism in cpconfig and reboot) that is sill NOT enough. You would need to remove the HA license and apply regular license for eother single gw or standalone. I would just apply an eval for the time being and make sure it works the way you wanted.

Makes sense?

So the moment I remove a member from a cluster.
yes quite clear now

Will this also affect the active node license?
Another question: If I remove a node from a cluster, do I have to perform any other actions on the active node? Can it affect the active node in any way?

Anyway then I will try to do a lab to test it, although in production we have S1C

Cluster will be broken,if you do this. Yes, I would 100% test it in the lab.

But my question is: I want to be able to delete a node from a cluster. and can the deleted node be recovered somehow, as a single standalone gateway? Or can't I do that because when I did the time wizard it was checked as part of a cluster?
In the lab I tried to delete a node from a cluster, but it didn't give me any problems....
Maybe it's better if i open an TAC

i follow this guide:

Removing a Member from an Existing Cluster

Thank you very much

Thats EXACTLY what I followed in the past. Here is the key...so does not matter how you did first time wizard, if you remove it from the cluster, you simply have to run cpconfig, disable cluster membership, reboot, thats it.

okay andy and so far I'm there, and I agree with you.
Once I perform these actions, my question is, can I connect it under the same CMA, but as a single gateway? or can I not?

Worked for me when I did it in the lab before, though regular mgmt, but cant imagine that would matter.

I will try on my own and let you know me too

thank you

Thats absolutely the best thing to do, agree.

Do you know how I can get an S1C for a lab?

Re: GW Monitor mode

the_rock — Thu, 03 Apr 2025 12:36:54 GMT

Not sure, honestly. Probably talk to your local SE about it.
