If I am using Windows Failover Clustering in a VMware HA / DRS cluster, with two WSFC VMs on two separate ESXi hosts using Physical Compatability Mode RDMs:
1. Can I put my hosts in maintenanance mode and have WSFC VMs vmotion off automatically?
2. Will DRS still work on the WSFC VMs?
No, vMotion and DRS is not supported if you are using shared disks.
VMware KB: Microsoft Clustering on VMware vSphere: Guidelines for Supported Configurations
vMotion, DRS not supported for MSCS clusters, attached storage is shared between specific ESX/ESXi hosts.
