Nexus 1000v secondary VSM hangs indefinitely
Hello All,

We are trying to stand up a couple nexus 1000v switches.  Both were deployed via an OVF template.  The primary happily accepted its role is primary.  When we set the secondary's role as secondary during the initial install it rebooted as expected, however now it just hangs at loading.  If I power the primary off the secondary will boot up.  I have verified all the vlan mappings are correct.  If I install these switches as standalone they can ping one another and their gateway.

I can't seem to sync the configs:

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
