Viewing IP Network Multipathing Group Status

To display the status of all Network Adapter Failover, or IP Network Multipathing, groups on a cluster, choose Nodes>[node name]>IPMP Groups from the navigation frame in SunPlexTM Manager.

Creating an IP Network Multipathing Group

When you create an IP Network Multipathing group, you must also add an adapter to the group.

To create an IP Network Multipathing group and add an adapter, complete the following steps:

  1. From the navigation frame in SunPlex Manager, choose Nodes>[node name]>IPMP Groups.

    The IP Network Multipathing Groups window appears.

  2. From the Action Menu, choose Create Group.

  3. Type the name of the new group to which you want to add an adapter.

  4. In the Adapter field, type the name of the adapter.

  5. In the Test Address field, type the test IP address.

  6. If you want a logical address assigned to the adapter, in the Logical Address field, type the IP address for the adapter.

  7. If you want the adapter configured as a standby adapter, check the Standby box.

    Note: A standby adapter does not host logical IP addresses. Also, a standby adapter does not take advantage of outbound load balancing.

  8. Click Create Group.

    SunPlex Manager displays a confirmation message, including the command that is used to complete the task. Write down or copy this command for future use in scripts and other automated tasks.

Removing an Adapter From an IP Network Multipathing Group

Remove an adapter from an existing IP Network Multipathing group to enable the adapter to be removed from the system, to be replaced, or to be configured for a different subnet and used for another IP Network Multipathing group.

Warning Removing the last adapter from an IP Network Multipathing group also deletes that IP Network Multipathing group. If you delete the IP Network Multipathing group, you might cause a loss of public network access for the cluster node.
