VPC link not working with vsphere

Hi all!  I'm pretty new to networking, so forgive me if I missed something obvious. I have a new HP Server running ESXi and joined to vsphere.  It has dual NICS and is connected to two Nexus 5000's.  I've connected a port from each NIC to each Nexus with vpc (the switches aren't stacked) and teaming on esxi using IP hashing.  Each link independently works, but as soon as I connect both, I lose access to the server (currently just working on the Managment vlan).  I know LACP is a thing, but our vsphere isn't licensed for it.  My goal is to have teaming working for network redundancy.

port config:

port channel config:

VPC and port channel status.

All the config is the same on both switches.

if the HP server not support LACP, then he need to use mode ON, 
active/passive is for only LACP 

LACP is a standard protocol... for sure HP servers support that...in almost 90% of vendors use lacp as a default protocol when enabled nic team/lag

 - Also check logs on both Nexus 5000 devices when you (try) to make the connection and check vsphere networking logs too
