Pacemaker on Db2 Linux HADR - ability to add more than 1 network interface as a resource

See this idea on ideas.ibm.com

We use 2 network interfaces in our Db2 server setup: one public and a private used by the HADR-traffic. Other servers even have more interfaces. I'd like to be able to add them as a pacemaker resource.

    One of our clients have separate networks for separate instances on one physical server, under surveillance of pacemaker. At this point we can only monitor one single public network interface. 
    In TSAMP we could add 2 network resources and create a VIP on either network. We need to be able -in view of network segregation- to set up different VIP's in separate networks, which was possible in TSAMP.

    This is an excerpt from a XML-configuration file that we used in TSAMP.

         <PhysicalNetwork physicalNetworkName="db2_public_network_1" physicalNetworkProtocol="ip">
         <Interface interfaceName="eth0" clusterNodeName="s598lp1dbrf01">
           <IPAddress baseAddress="10.197.20.4" subnetMask="255.255.255.0" networkName="db2_public_network_1"/>
         </Interface>
         <Interface interfaceName="eth0" clusterNodeName="s598lp2dbrf01">
           <IPAddress baseAddress="10.197.21.4" subnetMask="255.255.255.0" networkName="db2_public_network_1"/>
         </Interface>
        </PhysicalNetwork>
        <PhysicalNetwork physicalNetworkName="db2_private_network_5" physicalNetworkProtocol="ip">
         <Interface interfaceName="eth1" clusterNodeName="s598lp1dbrf01">
           <IPAddress baseAddress="10.197.108.42" subnetMask="255.255.255.0" networkName="db2_private_network_5"/>
         </Interface>
         <Interface interfaceName="eth1" clusterNodeName="s598lp2dbrf01">
           <IPAddress baseAddress="10.197.108.43" subnetMask="255.255.255.0" networkName="db2_private_network_5"/>
         </Interface>
        </PhysicalNetwork>

     

    thanks,
    Bart.

    Thank you for submitting this request. We are reviewing this and need more information.

    Could you please provide some details about how you intend to use this? What are you not able to do because this feature in not available? What benefit will having multiple network interfaces as Pacemaker resources deliver?
    What is the business impact associated with this request?

    Thank you for the details.
