When you create a protection group for array-based replication, you specify array information and then Site Recovery Manager computes the set of virtual machines into a datastore group. Datastore groups contain all the files of the protected virtual machines.

You can add virtual machines to a protection group by creating them on one of the datastores that belong to the datastore groups that Site Recovery Manager associates with the protection group. You can also add virtual machines to the protection group by using Storage vMotion to move their storage to one of the datastores in the datastore group. You can remove a member from a protection group by moving the virtual machine's files to another datastore.

If you disable protection on a virtual machine, you must move the files of that virtual machine to an unprotected datastore. If you leave the files of an unprotected virtual machine in a protected datastore, recovery fails for all the virtual machines in that datastore.

To configure array-based replication, you must assign each virtual machine to a resource pool, folder, and network that exist at the recovery site. You can specify defaults for these assignments by selecting inventory mappings. Site Recovery Manager applies inventory mappings when you create the protection group. If you do not specify inventory mappings, you must configure them individually for each member of the protection group. Site Recovery Manager does not protect virtual machines that you did not configure or that you incorrectly configured for replication, even if they reside on a protected datastore.

If your storage array supports consistency groups, Site Recovery Manager is compatible with vSphere Storage DRS and vSphere Storage vMotion. You can use Storage DRS and Storage vMotion to move virtual machine files within a consistency group that Site Recovery Manager protects. If your storage array does not support consistency groups, you cannot use Storage DRS and Storage vMotion in combination with Site Recovery Manager.
