Nevermind.  It appears that I had a typo in the Group Name when I configured the partner settings.  I didn't realize it would use the Group name as well as the IP.  Makes sense now that I think about it.  SMH
I am trying to setup replication from a 6100 (Primary,running v7.1.2) to a 6500 (Secondary, running v6.0.5).    After I configure the replication partner settings on both sides, and run a test from the Primary group, I get the following: 2475510:553:ESXSAN01:MgmtExec: 3-Jun-2015 08:12:57.620553:replTunnel.cc:1633:ERROR:7.4.80:Partner Bunsold-EQL-Grp: iSCSI: login failed. Make sure replication partnership is configured on the remote partner. The Primary is configured with a management network; but the Secondary is not.  The primary can ping the iscsi interfaces on the secondary from its iscsi interfaces. I am wondering if the different firmware versions are causing issues.  I was hoping to not have to update the Secondary (as it has other group with multiple devices already replicating to it).   Any ideas?
