If HP Scalable NAS must use a network that was configured to discourage administrative traffic, it will fail over to a network that allows the traffic as soon as that network becomes available to all servers in the cluster. If multiple interface failures occur on a server and there is not another network available for the administrative network, the server may drop out of the cluster. The remaining servers will continue to use the existing administrative network. Making network changes When making network changes, you should be aware of the following: • Do not add or delete an active network interface device from the operating system while HP Scalable NAS is running. Attempting to do this can adversely affect the entire cluster. If you need to add or delete an active network interface on a particular server, first stop HP Scalable NAS on that server. Then make your administrative change and start HP Scalable NAS. • An active network interface should not be modified or taken down via the operating system while HP Scalable NAS is running. Attempting to do this can cause adverse effects. If any part of a network interface definition needs to be changed, stop HP Scalable NAS on the affected server, shut down the network, and then make the change. When the change is complete, bring up the network and restart HP Scalable NAS on the node. Allow, discourage, or exclude administrative traffic By default, all network interfaces allow administrative traffic. However, you can specify which networks you prefer to use for this traffic. For performance reasons, HP recommends that these networks be isolated from the networks used by external clients to access the cluster. To allow or discourage administrative traffic on a network interface, select that network interface on the Servers window, right-click, and then select either Allow Admin. Traffic, Discourage Admin. Traffic, or Exclude Admin Traffic as appropriate. The setting is applied to all interfaces within the same subnet on all servers of the cluster. On the command line, issue the appropriate mx netif command: mx netif allowadmintraffic ... mx netif discourageadmintraffic ... mx netif excludeadmintraffic ... 82 Configure network interfaces
