HP Network config utility and VLAN's

[HPCustomer007]

Hi,
Just want to be sure it is the right config on the server side.
I want to have 2 VLANs on the same interface, one for server access and the other one for heartbeat between 2 servers.
I used HP network config utility to create a native untagged VLAN #1 as server-vlan and a 2nd VLAN #661, tagged this time, as the heartbeat-vlan.
I have assigned 10.17.201.1/18 IP addr for the server interface and 10.3.31.51/24 for the heartbeat interface. On a 2nd server I have assigned 10.17.201.2/18 IP addr for the server interface and 10.3.31.52/24 for the heartbeat interface.
I can reach server using server-vlan IP addr but 2 servers can't reach each other via heartbeat vlan.
I want to be sure that it is a problem coming from the switch configuration and not from the server configuration.
Thanks for your help

HP network config utility is the server NIC configuration.
You do not mention having done the same configuration on the switchport?

Network team did not set the good VLAN ID on the switch...
