Then, after reviewing the RPA VM settings, you may see that there is an extra vNIC assigned. The below image shows an example of it:
 
VM settings showing an extra vnic



RecoverPoint cluster network topology differs from the configuration of the VM.
In the example, RPA topology is "data is separated".
This kind of topology implies 1 vNIC for WAN+LAN traffic and 1 vNIC for data traffic, while the VM is configured with 3 vNIC.
NOTE: The example shown may differ from your environment. 
 

Resolution

Workaround:

Remove the extra vNIC attached to the RPA VM/s.

Go to RPA VM settings and remove the extra vNIC, see example below:

Remove the extra vNIC from the RPA/s VMs

NOTE: The example shown may differ from your environment. 

Resolution:

The issue stated in this article is not related to RecoverPoint functionalities, no change is needed at product level.
