+++ This bug was initially created as a clone of Bug #1842424 +++ NOTE: cloning as this request is still valid for RHOCP 4.6.z and higher. Document URL: https://docs.openshift.com/container-platform/4.4/scalability_and_performance/recommended-host-practices.html#master-node-sizing_ Section Number and Name: Master node sizing Describe the issue: Looks like the following description was written for IPI and changing instance type at IaaS layer. This description is confusing for UPI users. > Because you cannot modify the master node size in a running OpenShift Container Platform 4.4 cluster, you must estimate your total node count and use the suggested master size during installation. IN Baremetal UPI on vSphere, users can modify VM resource allocation without recreating the VM and increase the amount of CPU and/or memory. Suggestions for improvement: Clearly state that this note is talking about IPI instance type change. It's not talking about the amount of resources change of VM.
