Hi,
Can you share the exact command that you used to peer clusters? Check the Cluster UUIDs of each of the cluster using the following command from the Cluster prompt - ::> cluster identity show (Admin privileges, diagnostics reveal more details). However, the cluster UUID cannot be modified from cluster prompt since it's set at the time of creation. Try checking if there's an option at the loader prompt and use the following format:
setenv bootarg.mgwd.cluster_uuid XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
