Configuring a LIF

You must identify a LIF that will be used for establishing a data connection and control connection between the node and the backup application. After identifying the LIF, you must verify that firewall and failover policies are set for the LIF.

  1. Identify the intercluster LIF hosted on the nodes by using the network interface show command with the -role parameter.

    Example

    cluster1::> network interface show -role intercluster

    Logical Status Network Current Current Is
    Vserver Interface Admin/Oper Address/Mask Node Port Home
    ----------- ---------- ---------- ------------------ ------------- ------- ----
    cluster1 IC1 up/up 192.0.2.65/24 cluster1-1 e0a true
    cluster1 IC2 up/up 192.0.2.68/24 cluster1-2 e0b true
  2. Ensure that the firewall policy is enabled for NDMP on the intercluster LIFs:
    1. Verify that the firewall policy is enabled for NDMP by using the system services firewall policy show command.

      Example

      The following command displays the firewall policy for the intercluster LIF:

      cluster1::> system services firewall policy show -policy intercluster

      Vserver Policy Service Allowed
      ------- ------------ ---------- -------------------
      cluster1 intercluster dns -
      http -
      https -
      ndmp 0.0.0.0/0, ::/0
      ndmps -
      ntp -
      rsh -
      ssh -
      telnet -
      9 entries were displayed.
    2. If the firewall policy is not enabled, enable the firewall policy by using the system services firewall policy modify command with the -service parameter.

      Example

      The following command enables firewall policy for the intercluster LIF:
      cluster1::> system services firewall policy modify
      -vserver cluster1 -policy intercluster -service ndmp 0.0.0.0/0

  3. Ensure that the failover policy is set appropriately for the intercluster LIFs:
    1. Verify that the failover policy for the intercluster LIFs is set to local-only by using the network interface show -failover command.

      Example

      cluster1::> network interface show -failover
      Logical Home Failover Failover
      Vserver Interface Node:Port Policy Group
      -------- --------------- ----------------- ------------ --------
      cluster1 IC1 cluster1-1:e0a local-only Default
      Failover Targets:
      .......
      IC2 cluster1-2:e0b local-only Default
      Failover Targets:
      .......
      cluster1-1 cluster1-1_mgmt1 cluster1-1:e0m local-only Default
      Failover Targets:
      .......
    2. If the failover policy is not set appropriately, modify the failover policy by using the network interface modify command with the -failover-policy parameter.

      Example

      cluster1::> network interface modify -vserver cluster1 -lif IC1 -failover-policy local-only
