Reconfiguring extension nodes and extension node adapters

After extension node and extension node adapter information has been changed in the SDR, the extension node SNMP Agent must be notified.

If the switch automatic unfence feature is enabled and the extension node is in the autojoin state, the node should automatically join the switch after it tests ready. To bring the extension node on the switch if the automatic unfence feature has been disabled or if the extension node is not in the autojoin state, run the Eunfence command after the extension node has been reconfigured.

From SMIT

Use the SMIT menus for adding or changing extension node information as described in Adding extension nodes and extension node adapters and Changing extension nodes and extension node adapters. Specify yes for Reconfigure the extension node?.

SMIT menus are also provided that invoke the enadmin command.

1. Access the RS/6000 Cluster Management menu:

   ENTER

   smit cluster_mgmt

   • The RS/6000 Cluster Management menu appears.

2. Run the enadmin command:

   SELECT

   Run enadmin Command

   • The Extension Node Management menu appears.

   ENTER

   Enter values to manage the extension node:

   Action to be performed on the extension node

   reconfigure or reset.

   Node Number

   The number ID assigned to the extension node.

   SELECT

   OK

From the command line

1. Use the endefnode -r command to reconfigure extension nodes.
2. Use the endefadapter -r command to reconfigure extension node adapters.
3. As an alternative to using endefnode -r and endefadapter -r, you can use the enadmin command to notify the SNMP Agent managing the extension node to request updated configuration information from the SP SNMP Manager (the spmgrd daemon) running on the control workstation.

See the book PSSP: Command and Technical Reference for details on these commands.
