Thread: Trunk Port, VLANS, Virtual IP failover and differing subnets

    Ok, I am still not understanding something. In the "How to Setup DSS V6 iSCSI Failover with XenServer using Multipath", on page 3, there is a diagram. It lists all of the interfaces on both the primary and the secondary nodes as "Auxiliary connection (Heartbeat)". But if the physical interface that is connected to a switch is not on a trunked port with VLAN how would that heartbeat work as the Virtual IP (on a different subnet) would be the only one routable. Thus when the primary is working and has the Virtual IP on eth1 and eth2, the secondary has not IP on a routable subnet since it's physical interface IP would not be routable (unless the port is connected to is trunked).

    What am I missing or not understanding here? This is making my setup of Open-E DSS extremely difficult and frustrating.

    Some help would be greatly appreciated!

    thanks,
    -Tomas

    this thread is full of confusion ....lol

    Just for grins, set up dss nics in seperate subnets(as shown) with the VIP also in seperate subnets. set your default gateway on the default management port.
    Go to the console(CNTRL+ALT+T) and try to ping the other servers IP's.
    No need for VLANS, just make proper gateway assignment, and configure router accordingly.
    Even if the machines are connected together on the same switch, you should be fine.

    I guess I am not grinning or laughing and still don't have it working right.

    Here is my current setup:
    DSS:
    Interfaces:
    eth0 - 192.168.137.102/255.255.255.0, BC: auto, GW: 192.168.137.240
    eth1 - 10.100.101.4/255.255.255.0, BC: auto: GW:

    Default GW: eth0 192.168.137.240

    Failover:
    eth0 -
    eth1 - Virtual IP: 10.100.100.4/255.255.255.0, BC: 10.100.100.255, GW:
    (NOTE: when I use this Virtual IP I get the message that "The entered Virtual IP is in the same subnetwork as one of the network interfaces or Virtual IPs that already exist in the system.
    It is recommend to use IP that has a unique subnetwork class and is not used in any other place in your configuration.
    Do you want to continue?")
    As far as I can tell it is in a different subnet and not used anywhere else.

    Server:
    bond0 - 192.168.137.104 BC:192.168.137.255/255.255.255.0, GW: 192.168.137.240
    eth1.800 - 10.100.100.13/255.255.255.0, BC: 10.100.100.255, GW:

    Ping Test from DSS to 10.100.100.13 fails

    If I setup the following and remove the Virtual IP then I can ping the server:
    DSS:
    Interfaces:
    eth0 - 192.168.137.102/255.255.255.0, BC: auto, GW: 192.168.137.240
    eth1 - 10.100.100.4/255.255.255.0, BC: auto: GW:

    Default GW: eth0 192.168.137.240

    Failover:
    eth0 -
    eth1 -

    Server:
    bond0 - 192.168.137.104 BC:192.168.137.255/255.255.255.0, GW: 192.168.137.240
    eth1.800 - 10.100.100.13/255.255.255.0, BC: 10.100.100.255, GW:


    So I'm still stuck and not making any headway?
    Can anyone help me un-muddle this?

    Additional information:
    DSS:
    eth0 is on vlan 100
    eth1 is on vlan 800

    Server:
    bond0 is attached to eth0 and is in vlan 100
    eth1.800 is on vlan 800

    thanks,
    -Tomas
