When you say "attached to z/VM x.x and z/VM assigned" do you mean that the OSA is available to VM, or that it's attached to VM TCPIP? You want it to be available to VM and attached directly to the guest or under the control of a VSWITCH. > If there is qetharp for ARP equivalent on zLinux, is there > any other network teaming software that is equivalent with > bonding? qethbonding? As others have said, link bonding isn't what you want to do here unless you are trying to aggregate bandwidth; if I understand you correctly, you want to do IP or MAC address takeover for HA. If so, then you should look at the packages in openssi.org wrt to the cluster IP address takeover code. It relies on the ability to see and react to raw frames on the wire, so you need to solve the OSA/VSWITCH layer 2/layer 3 question first (you really want layer 2 support for this application). If you have to do this at layer 3, then you can do some source IP munging with the ip-route2 advanced routing package and having your network routers accept specific host routes for your virtual IP address from routing software running on the linux guests. Be warned -- this is possible, but it will *not* be a trivial configuration exercise. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
