we have windows 2019 fail over cluster running as (CAB) cluster across box and have physical RDM in use in cluster disk resources. I would like to know correct steps for case of adding more space to RDM and reflecting same in windows failover cluster in disk resources
- it requires down time or can be performed while cluster is operational?
- please provide step by step guidance starting from storage and then at vmware and finally in guest OS (two nodes)
if require any further details, please let me know.
