vMotion Microsoft Cluster VMs

vSphere supports three different configurations of Microsoft Cluster Service (MSCS):

• Clustering MSCS VMs on a single host (aka a cluster in a box - CIB)
• Clustering MSCS VMs across physical hosts (aka a cluster across boxes - CAB)
• Clustering physical machines with VM

see Setup for Failover Clustering and Microsoft Cluster Service, ESXi 6.0 for more information.

However, vMotion is supported only for CAB with pass-through RDMs. Do not vMotion MSCS VMs in the other two configuration.

In addition, do not vMotion MSCS VMs to a VSAN storage, because VSAN does not support thick provision and SCSI bus sharing on the VM SCSI adapter. The VM will not be able to power on with the error message “Cannot use non-thick disks with clustering enabled (sharedBus='physical'). The disk for scsi1:0 is of the type thin.”
