Nutanix VM replication requires every source storage container to be mapped to a destination container. The Linux VMs succeed because their source container has an existing mapping on the remote cluster, whereas the Windows-based Marketing VMs reside in a container that has no mapping. In that circumstance, Prism blocks replication even though network connectivity, free capacity, and scheduling parameters are all valid.

B. Replication mode (Async vs NearSync) does not influence whether a container is addressable on the target; mode changes merely affect RPO.

C. Cluster capacity is reported healthy; a missing mapping—not lack of space—prevents the transfer.

D. Linux VMs replicate successfully, proving that the replication mode in use is not the root cause.
