Configuring Inventory Mappings
Inventory Mappings are used to link objects between the protected and recovery sites while recovering the protected virtual machines. Inventory mappings must be configured before creating a protection group.
Mapping can be done in two ways: Automatic or Manual. For more information, refer to the following article: https://docs.vmware.com/en/Site-Recovery-Manager/8.1/com.vmware.srm.admin.doc/GUID-DEA90D45-A6DE-48F5-8489-0CFA6D1DF3CB.html.
