Attempting to configure VMware SRM (Site Recovery Manager) Protection Group fails with: "... due to unresolved devices"

Problem

You attempt to configure a new VMware SRM protection group but receive the following error:

ERROR

Operation Failed Task completed with error CompositeException Unable to protect VM '<virtualMachineName>' due to unresolved devices Unable to protect VM '<virtualMachineName>’ due to unresolved devices Unable to protect VM '<virtualMachineName>' due to unresolved devices

Operation ID: 33a8561f-c6b5-4868-b2f7-01453d762ad6

Solution

This error is usually thrown due to components of SRM not being completely configured. The following are a few common items:

1. Network Mappings
2. Folder Mappings
3. Resource Mappings

There will be times when the administrator has configured the mappings the configuration in the mapping may not be correct and the best way to identify exactly what is preventing the protection group from being configured is to navigate to the Virtual Machines tab and review the Protection Status output, which would explicitly display the problem. In the case of this example, the network mappings were configured but various port groups and cluster mapping for these VMs were not configured:

The configuration for the Protection Groups should successfully complete once the missing mappings are configured:
