Below are few scenarios done - one subnet added to cpms cluster yaml , no effect on cluster , no new machines provisioning happened.

once cpms yaml corrected , cluster back to normal all co good.
These are the basic scenarios I tested till now , let me know if we can check any other scenario ,
I think we can try creating a different and one more subnet on Azure portal for master , and update them in cpms , checked with installation we can have a scenario once https://issues.redhat.com/browse/CORS-2658 is ready to go.
