Modifying the settings of a virtual machine that is included in a protection group, to add or change storage devices, such as hard disks or DVD drives, can affect the protection of that virtual machine.

If you add a device to a virtual machine that you protect by using vSphere Replication, you must reconfigure vSphere Replication on the virtual machine to select the replication options for the new device. For information about reconfiguring vSphere Replication settings, see Reconfiguring Replications.

After you modify virtual machines in a vSphere Replication protection group, you must reconfigure protection for any virtual machines that have a status of Not Configured, Device Not Found, Unresolved Devices, or Mapping Missing. See Apply Inventory Mappings to All Members of a Protection Group and Configure Inventory Mappings for an Individual Virtual Machine in a Protection Group.
