Network Trouble with vSphere 6 using VLAN and HP Switches

Greetings everybody !

I'm running out of ideas with my problem, so I hope someone can help me deal with it Smiley Happy

I got a VMWare infrastructure running under vSphere 6.0 with 3 clustered ESXi, connected to 2 HP switches.

On my third ESX, I have 2 virtual machines each connected to both VLAN 1 and VLAN 100 (2 virtual network card per VM)

VLAN 1 is my DATA network

VLAN 100 is my VOICE network

On VLAN1, everything works, all VM and switches are able to ping each others.

On VLAN100 :

- The first HP switch can ping the first VM but not the second

- The second HP switch can ping the second VM but not the first

Each VM can ping between each other

Each ESx has 2 physical network cards with 4 ports per card.

2 ports of each physical network card are connected to each switch.

Here's the network scheme :  http://imageshack.com/a/img921/776/dCIk0s.jpg

Here's the 2 HP switches configuration :

Could you further explain the problem. You say that all VMs on VLAN 100 can talk.

Each VM can ping between each other
