6.5.1 How to Add Switches and SCI Cards

Use this procedure to add switches and SCI cards to cluster nodes. See the sm_config(1M) man page for details.

1. Edit the sm_config template file to include the configuration changes.

   Normally, the template file is located in /opt/SUNWsma/bin/Examples.

2. Configure the SCI SBus cards by running the sm_config(1M) command from one of the nodes.

   Rerun the command a second time to ensure that SCI node IDs and IP addresses are assigned correctly to the cluster nodes. Incorrect assignments can cause miscommunication between the nodes.

3. Reboot the new nodes.
