How to Replace Cluster Transport Adapters

You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster will not function properly without a functioning cluster interconnect.

1. Shut down the node with the cluster transport adapter you want to replace.

   # scswitch -S -h nodename # shutdown -y -g 0

   For the procedure on shutting down a node, see Sun Cluster 3.0 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. Disconnect the cluster transport cable from the cluster transport adapter and other devices.

   This procedure is the same in a non-cluster environment. For the procedure on disconnecting cables from cluster transport adapters, see the documentation that shipped with your network adapter and node.

4. Replace the cluster transport adapter.

   This procedure is the same in a non-cluster environment. For the procedure on replacing cluster transport adapters, see the documentation that shipped with your network adapter and node.

5. Reconnect the cluster transport cable to the new cluster transport adapter.

   This procedure is the same in a non-cluster environment. For the procedure on connecting cables to cluster transport adapters, see the documentation that shipped with your network adapter and node.

6. Power on and boot the node.

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

Where to Go From Here

If you are performing an initial installation of cluster hardware, see "Installing Cluster Transport Junctions". If you have Sun Cluster software installed, the cluster transport adapter you replaced appears in the Sun Cluster software configuration, and you want to reconfigure Sun Cluster with the new cluster transport adapter, see Sun Cluster 3.0 System Administration Guide.
