Cause

You must create the correct Replication Interfaces before creating the Replication Connection between a Local and Remote system.

Resolution

  1. Remove the faulted Replication Connection.
Note: Do not bypass the step to remove the Replication Connection.  If you do, and create the Replication Interfaces, the Replication Session creation will fail. You must remove the faulted Connection and then follow the correct order shown below.
  1. Create the appropriate Replication Interfaces on the Local and Remote systems.
  2. Create the Replication Connection.
  3. Create Replication sessions on the appropriate NAS Server or Block LUN/Consistency Group resource.
