Inventory Mappings for Array-Based Replication Protection Groups
and vSphere Replication Protection Groups
For array-based protection and vSphere Replication protection, Site Recovery Manager applies inventory
mappings to all virtual machines in a protection group when you create that group.
Site Recovery Manager creates a placeholder virtual machine when you create an array-based or
vSphere Replication protection group. Site Recovery Manager derives the resource assignments for the
placeholder from the site-wide inventory mappings.
If you configure site-wide inventory mappings, you can reapply the inventory mappings to a protection
group whenever necessary, for example if you add new virtual machines to an existing protection group.
If you change the site-wide inventory mappings for a site, the changes do not affect virtual machines that
Site Recovery Manager already protects in an existing protection group. Site Recovery Manager only applies
the new mappings to previously protected virtual machines if you reconfigure protection on them.
Site Recovery Manager cannot protect a virtual machine unless it has valid inventory mappings. However,
configuring site-wide inventory mappings is not mandatory for array-based replication protection groups
and vSphere Replication protection groups. If you create an array-based replication protection group or
vSphere Replication protection group without having defined site-wide inventory mappings, you can
configure each virtual machine in the group individually. You can override site-wide inventory mappings
by configuring the protection of the virtual machines in a protection group. You can also create site-wide
inventory mappings after you create a protection group, and then apply those site-wide mappings to that
protection group.

Because placeholder virtual machines do not support NICs, you cannot change the network configurations
of placeholder virtual machines. You can only change the network for a placeholder virtual machine in the
inventory mappings. If no mapping for a network exists, you can specify a network when you configure
protection for an individual virtual machine. Changes that you make to the placeholder virtual machine
override the settings that you establish when you configure the protection of the virtual machine.
Site Recovery Manager preserves these changes at the recovery site during the test and recovery.
Inventory Mappings for Storage Policy Protection Groups
For storage policy protection, Site Recovery Manager applies inventory mappings to virtual machines when
you run a recovery plan that contains a storage policy protection group.
With array-based and vSphere Replication protection groups, Site Recovery Manager applies inventory
mappings at the moment that you configure protection on a virtual machine. With storage policy protection
groups, because storage policy protection is dynamic, Site Recovery Manager only applies the inventory
mappings at the moment that you run a recovery plan. Virtual machine placement decisions are made
according to the inventory mappings when a recovery plan runs, so Site Recovery Manager does not create
placeholder virtual machines on the recovery site.
