Hello
We have replication set up between 2 HX clusters. I notice we can only map 1 source datastore to 1 destination datastore. Do I need to map every datastore from source to destination? The VM I want to protect does not live on the mapped datastore, so it looks like I can't protect it until I move it. It would be nice to map many source DS to 1 destination DS. I'm looking for information on the practical applications here. How are others using and configuring this feature?
Thanks

Hi Robert.
Creating a replication cluster pair is a prerequisite for configuring VMs for replication. After two (2) HX clusters are paired, map the datastore on the remote cluster to a datastore on the local cluster.
Mapping datastore A on HX cluster 1 with a datastore B on HX cluster 2 enables any VM on HX cluster 1 that resides in datastore A and is configured for replication to be replicated to datastore B on HX cluster 2. Similarly, any VM on cluster 2 that resdies in datastore B and is configured for replication to be replicated to datastore A on HX cluster 1.
Pairing is strictly 1-to-1. A cluster can be paired with no more than one other cluster.
Mapping is a strict 1-to-1 relationship. A datastore on a paired HX cluster can be mapped to no more than one datastore on the other HX cluster. Note that there can be multiple mapped datastores. For example, datastore A on HX cluster 1 mapped to datastore B on HX cluster 2, and datastore C on HX cluster1 mapped to datastore D on HX cluster 2.
Note | Once a local datastore is mapped to a remote datastore, the corresponding local datastore will not appear under Other DRO Protection. |
You have to have your guestVMs on datastores that are mapped. Now keep in mind you can map multiple datastores, but each source and destination needs to be a unique pairing.
