How to Remove Cluster Transport Adapters

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

1. Verify that the cluster transport adapter you want to replace appears in the Sun Cluster software configuration.

   • If the cluster transport adapter you want to remove appears in the Sun Cluster software configuration, remove the cluster transport adapter from the Sun Cluster configuration. To remove a cluster interconnect, follow the procedures in the Sun Cluster 3.0 System Administration Guide before going to Step 2.

   • If the cluster transport adapter you want to remove does not appear in the Sun Cluster software configuration, go to Step 2.

2. Shut down the node with the cluster transport adapter you want to remove.

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

   For the procedure on shutting down a node, see the Sun Cluster 3.0 U1 System Administration Guide.

3. Power off the node.

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

4. Disconnect the cluster transport cables from the cluster transport adapter you want to remove.

   This procedure is the same as the procedure 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.

5. Remove the cluster transport adapter.

   This procedure is the same as the procedure in a non-cluster environment. For the procedure on removing network 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 the Sun Cluster 3.0 U1 System Administration Guide.
