Both issues have been resolved
"Unable to find a matching consistency group at the local site for the remote consistency group".
Resolved by reconfiguring a datastore, rescanned my ESX storage, and was able to identify and add the new server to the appropriate VM Protection Group.
"Operation Failed. There are not enough licenses installed to perform the operation."
Resolved by removing my SRM licenses in vSphere, stopping and restarting the SRM services on the SRM Windows servers, and re-adding the SRM licenses in vSphere. Before and After showed the same number of licenses being consumed (still under the license count threshold), not sure what changed, but this resolved the error msg.
