5.1.2 How to Add Cluster Transport Cables and Transport Adapters

1. Ensure that the physical cluster transport cables are installed.

   For the procedure on installing a cluster transport cable, see the Sun Cluster 3.0 Hardware Guide.

2. Become superuser on any node in the cluster.

3. Execute the scsetup utility.

   # scsetup

   The Main Menu appears.

4. Access the Cluster Interconnect Menu by entering 2 (Cluster interconnect).

5. Add the cable by entering 1 (Add a transport cable).

   Follow the instructions and enter the requested information. A junction is not needed for direct connections in a cluster with two nodes. However, you need to enter both the node and the adapter names of one of the endpoints of the cable you are trying to identify.

   >>> Add a Cluster Transport Cable <<<     ...     Is it okay to continue (yes/no) [yes]? <Return>     ...     To which node do you want to add the cable? nodename     Name of the adapter to use on "node"? adaptername     Name of the junction at the other end of the cable? junctionname     Okay to use the default for this cable connection [yes]? <Return>     Is it okay to proceed with the update (yes/no) [yes]? <Return>

6. Add the adapter by entering 2 (Add a transport adapter to a node).

   Follow the instructions and enter the requested information. A junction is not needed for direct connections in a cluster with two nodes. However, you need to enter both the node and the adapter names of one of the endpoints of the cable you are trying to identify.

   >>> Add a Cluster Transport Adapter <<<     ...     Is it okay to continue (yes/no) [yes]? <Return>     ...     To which node do you want to add the cable? nodename     Name of the adapter to use on "node"? adaptername     Name of the junction at the other end of the cable? junctionname     Okay to use the default for this cable connection [yes]? <Return>     Is it okay to proceed with the update (yes/no) [yes]? <Return>

7. Verify that the cluster transport cable or transport adapter is added.

   # scconf -p | grep cable # scconf -p | grep adapter

5.1.2.1 Example--Adding a Cluster Transport Cable and a Transport Adapter

The following example shows how to add a transport cable or transport adapter to a node using the scsetup command.
