How to Add Host Adapters

This section contains the procedure for adding host adapters to nodes in a running cluster. For conceptual information on host adapters, see the Sun Cluster 3.0 12/01 Concepts document.

1. Shut down the node in which you are installing the host adapter.

   # scswitch -S -h nodename # shutdown -y -g0 -i0

   For the procedure on shutting down a node, see the Sun Cluster 3.0 12/01 System Administration Guide.

2. Power off the node.

   For the procedure on powering off a node, see the documentation that shipped with your node.

3. Install the host adapter.

   For the procedure on installing host adapters and setting their DIP switches, see the documentation that shipped with your host adapter and node hardware.

4. Power on and boot the node.

   # boot -r

   For the procedures on powering on and booting a node, see the Sun Cluster 3.0 12/01 System Administration Guide.

Where to Go From Here

When you are finished adding all of your interconnect hardware, if you want to reconfigure Sun Cluster with the new interconnect components, see the Sun Cluster 3.0 12/01 System Administration Guide for instructions on administering the cluster interconnect.
