Changing network interface attributes

Edit online

You cannot change the attributes of a network interface dynamically. You must stop and restart cluster services for the changes to take effect in the configuration.

About this task

To change a network interface for a cluster, complete the following steps:

Procedure

  1. From the command line, enter smit sysmirror
  2. In SMIT, select Cluster Nodes and Networks > Manage Networks and Network Interfaces > Network Interfaces > Change/Show a Network Interface, and press Enter.
  3. Select the network interface from the picklist.
  4. Enter the field values as follows:
    Table 1. Network Interface fields
    Field Value
    Node Name The name of the node on which this network interface physically exists.
    Network Interface The network interface that is associated with the communication interface.
    IP Label/Address The IP label or IP address that is associated with this communication interface that is configured on the network interface when the node starts up. The picklist filters out IP labels or IP addresses already configured to PowerHA® SystemMirror®.
    Network Type Displays the network type for the selected network interface. You cannot edit this field.
    Network Name Enter a unique name for this network interface.
  5. Verify your changes are correct, and press Enter. PowerHA SystemMirror now checks the validity of the configuration. If a node cannot be reached, you might receive a warning
  6. Synchronize the cluster.
