What is the proper way to shut down a cluster?
We have been testing to find a way to have a node shutdown without the VMs moving all over the place.
We have a three node cluster in production, but to test different shutdown procedures I have set up a 2 node cluster with a share in Node and File Share majority.
My goal is to shut down the cluster without any of the VMs moving to a different host.
Thus far I have tried pausing the nodes with Do NOT Drain Roles specified. I have one role off and the other running. I understand that in an HA cluster that ideally you would want all of your roles to transfer to an online host whether they are running or not, but there has to be a way to force the role to stay where it is on failure. Right now, if we have to shut down our cluster in the event that power is out and we run out of battery, we do not know where a VM will be when they come back online.
I understand we can specify a preferred node for the VM, but is there a way to set the cluster up so that when a node is shut down the VMs do not transfer? We are looking to create a powershell script to run from the UPS when we reach a certain run time, but I have no idea what the process is, so I don't know how to get my script in line.
Any suggestions will be appreciated. Until then I will keep reading and testing.
Thank You
