I propose two VLANs setup (4paths configuration) but the client is saying that they prefer to setup iSCSI with only a single VLAN.

They bound the two network ports at the host side and only want a single VLAN setup.  I have highlighted the redundancy is done using multi-pathing so they do not need the network bounding.  What could be the potential issue with this kind of setup?  Both network ports are bounded as one interface I will assume it only has 1 IP address and 1 mac address.  Through in theory this should work.
