Use this procedure to reduce the node CPU and memory resources when not also increasing SDS disk size or a upgrading software. For example, when removing a product.
Before you begin
You must plan a maintenance window to perform this task.
Procedure
Edit the solution configuration spreadsheet that you previously downloaded from the support site. Enter values to reduce the CPU and memory resources.
On the cluster_config tab, modify the node-properties-cpu and node-properties-ram values as required.
Power off the cluster nodes.
In vCenter, on each cluster node VM, edit the settings to reduce the CPU and memory resources as required.
Power on the cluster nodes.
Log in to Cluster Control Manager using your customer account.
Wait approximately 30 minutes, then run ccm smoke-test on Cluster Control Manager and confirm that all tests pass.If ccm smoke-test fails, run it again in 10 minutes. If the test continuously fails for over an hour, contact your technical support representative.
Result
After this procedure, the cluster nodes are running with the new CPU and memory resource allocations.
