Cisco Nexus vPC unable to Ping port-channel server

Stryderusa

Level 1

Non-Cisco network guy here just learning Cisco.  I have setup vPC on two Nexus 9300 series switches - configured vpc peer keep-alive link, peer link, etd.  i am not doing any special L3 routing except for the peer keep-alive link and inter-VLAN routing.  Everything seems to be working with the vPC configuration - status show "up" and "successful".  However, when I try to Ping any of my ESXi servers connected to these Nexus 9300 switches via virtual port-channels I get "no route to host" error messages.  Note that ESXI vmkernel ports configured as regular access ports are reachable via Ping.  This makes me think there must be a problem with the vPC configuration somewhere.  Please help.
