HP Trunking to ESXi 5.1 - IP disconnect

Hi,

I have a weird anomaly with a brand new fresh install of ESXi 5.1 on two new Dell PowerEdge 1950s.

I setup the HP switch and ESXi networking just like the below link:
http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1004048&sliceId=1&docTypeID=DT_KB_1_1&dialogID=206986211&stateId=0%200%20202116152

The vsphere management IP is 192.168.5.16 on vlan 115 (this is a brand new subnet with no other conflicting IPs).

HP switch commands:
trunk 15-16 trk21 trunk
vlan 115 tagged trk21

I can't access 192.168.5.16, no ping, nothing.

I then change the IP address to 192.168.5.17 and whola, I'm able to ping and access it? Very weird.

On an identical server with identical HP switch trunking using trk20 I can ping it 192.168.5.15 and access vsphere via that IP address. I leave it overnight and come back in the morning and its no longer accessible with IP address 192.168.5.15, just for kicks I change it to 192.168.5.16 and its accessible for a while and then is inaccessible again?

In vsphere both hosts have the vswitch0 configured with the two NICs to be active and I only changed the load balancing to IP Hash. That's it.

Anybody have any clue?

Think I might have just found the problem. I've applied this link:

So far so good. I'll let you know.
