Removing a Cluster

[Former Member]

Hi,

I have four machines which are clustered together. The environment is quite unstable at the moment and there is no need for this cluster. I would like all four machines to be stand alone, but have found that making changes to any machine is quite risky as all of the machines are affect - naturally as they are clustered. Any advice on how to safely remove the four machines from this cluster? I can see the four notes when logging into any of the Central Management Console and also the Server Intelligent Agent has reference to the other machines under the Startup Tab Remote CMS connections.

I have machine1 - 4. One of the machines is XI 3.1 and the others are XI 3.0

It is in a Windows environment with MYSQL120 for the repository.

It is my understanding that I would need to stop the MYSQL120 service and then log in to the CMS and delete the nodes for the other servers, would this be required on all four machines?

Kind Regards,

Fiona

I don't have the actual steps but I think you can

a) create a new sia (with all services)

b) point the new sia to a new CMS DB

c) stop the old sia

the server should now be stand alone (with a blank DB)

You will likely need to delete the node from the cluster DB until the last server is left.

Also to note it's not supported to cluster different patch levels 3.1 and 3.0 so this could cause unforseen problems with the process.

Thanks for your response Tim.

I will be looking at attempting this next week.

If I were to create a new SIA with all the servers for only that one machine, and stop the old SIA won't the other four machines then have problems as they still refer to the machine I've changed in their cluster? I had a similar problem the other day I tried stopping one of the SIA and then I couldn't get into any of the machines, it's really fragile at the moment.

Thanks again,

Fiona
