Hello Gents,
I cought into weird situation after upgrade VMware ESXi 5.0 to 5.1 on UCS C200M2. Before upgrade I have had server with configured static adapter-fex VNICS and floating/dynamic vm-fex interfaces working perfectly in DirectPathIO mode for VMs. Initial deployment was done according Cisco N5K VM-fex operation guide for NX-OS 5.1(3)N1(1). There were vCenter 5.1, 2xN5K and 2xC200M with ESXi 5.0 integrated so that N5K DVS was brought to vCenter and hosts could be added to DVS. One of C200M2 (still on ESXi5.0) has no problem while operating VM-Fexs and adapter-fexs while part of its uplinks are on VSS and othe part on DVS (in fact there are none VMs on VSS, so all the workloads use DVS).
But upgraded C200M cannot operate with DVS correctly: any vmks, vm networks, VMs connected to DVS lose network connectivity.
Attached picture illustrates diag of connectivity status (uplinks/ets are blocked).
VEM are fresh and running:

Do anybody have an idea why it is going wrong?
