Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

ProcedureHow to Test IP Network Multipathing Groups

If you perform this test, you can verify that IP addresses failover from one adapter to another adapter within the same IP Network Multipathing group.

  1. Verify that all network adapters are active.

    # scstat -i
  2. Disconnect one public network cable from an active network adapter.

  3. Verify that the network adapter status displays as Failed.

    # scstat -i
  4. Ensure the IP address failed over to another adapter.

    # ifconfig -a
  5. Reconnect the public network cable to the network adapter.

    • If failback is set to yes in the /etc/default/mpathd file, the IP address automatically returns to the original network adapter.

    • If failback is not set to yes, the IP address remains with the new adapter until you perform a manual switchover.

      For more procedures about how to move an IP address to another adapter, see your Sun Cluster system administration documentation.

  6. Repeat Step 1 to Step 5 for each active adapter.
