When you create, clone, or relocate a virtual machine, Storage DRS generates only one placement recommendation.
Storage DRS generates a single placement recommendation when you create, clone, or relocate a virtual machine. No alternative recommendations are provided when multiple alternative recommendations are expected.
If the destination host explicitly specifies the virtual machine's swap file location as a datastore in the target datastore cluster, the disks to be placed in that cluster do not form a single affinity group. Storage DRS generates alternative placement recommendations only for a single item or a single affinity group.
Accept the single recommendation. To obtain multiple recommendations, choose a destination host that does not specify that the virtual machine swap file location is on a datastore that is in the target datastore cluster.
