Installing Cluster Transport Adapters
This section provides the procedure for adding cluster transport adapters. Use this procedure as part of the initial cluster hardware installation. Also use this procedure if you want to install cluster transport adapters after a Sun Cluster software installation.
For conceptual information on cluster transport adapters, see Sun Cluster 3.0 Concepts.
How to Install Cluster Transport Adapters
-
Shut down the node in which you will install the cluster transport adapter.
# scswitch -S -h nodename # shutdown -y -g 0
For the procedure on shutting down a node, see Sun Cluster 3.0 System Administration Guide.
-
Power off the node.
For the procedure on powering off a node, see the documentation that shipped with your node.
-
Install the cluster transport adapter.
This procedure is the same procedure in a non-cluster environment. For the procedure on installing host adapters, see the documentation that shipped with your network adapter and node.
-
Power on and boot the node.
For the procedures on powering on and booting a node, see Sun Cluster 3.0 System Administration Guide.

If you are performing an initial installation of cluster hardware, see "Installing Cluster Transport Junctions". If you have Sun Cluster software installed and want the cluster transport adapter you added to appear in the Sun Cluster configuration, see Sun Cluster 3.0 System Administration Guide.
Replacing Cluster Transport Adapters
This section provides the procedure for replacing cluster transport adapters.
For conceptual information on cluster transport adapters, see Sun Cluster 3.0 Concepts.
How to Replace Cluster Transport Adapters
Caution - 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.
-
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.
-
Power off the node.
For the procedure on powering off a node, see the documentation that shipped with your node.
-
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.
-
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.
-
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.
-
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.
Removing Cluster Transport Adapters
This section provides the procedure for removing cluster transport adapters.
For conceptual information on cluster transport adapters, see Sun Cluster 3.0 Concepts.
How to Remove Cluster Transport Adapters
Caution - 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.
-
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 replace appears in the Sun Cluster software configuration, remove the cluster transport adapter from the Sun Cluster configuration. To remove a cluster interconnect, see the Sun Cluster 3.0 System Administration Guide, then proceed to Step 2.
-
If the cluster transport adapter you want to replace does not appear in the Sun Cluster software configuration, proceed to Step 2.
-
-
Disconnect any cluster interconnect connections cabled to the cluster transport adapter.
This procedure is the same procedure in a non-cluster environment. For the procedure on disconnecting network connections from cluster transport adapters, see the documentation that shipped with your network adapter.
-
Shut down the node with the cluster transport adapter you want to remove.
# scswitch -S -h nodename # shutdown -y -g 0
For the procedure on shutting down a node, see Sun Cluster 3.0 System Administration Guide.
-
Power off the node.
For the procedure on powering off a node, see the documentation that shipped with your node.
-
Disconnect the cluster transport cables 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.
-
Remove the cluster transport adapter.
This procedure is the same in a non-cluster environment. For the procedure on removing cluster transport adapters, see the documentation that shipped with your network adapter and node.
-
Power on and boot the node.
For the procedures on powering on and booting a node, see Sun Cluster 3.0 System Administration Guide.
Installing Cluster Transport Junctions
A cluster with two nodes can use a point-to-point connections, requiring no transport junctions. A cluster with more than two nodes requires two transport junctions, which are Ethernet-based switches (customer-supplied), to provide means of communication among all nodes in the cluster.
Installing Cluster Transport Cables
This section provides the procedure for cabling the cluster transport.
How to Install Cluster Transport Cables
-
Locate the host adapters.
When cabling the cluster interconnect, be aware that the location of the host adapters might differ by platform. For example, some platforms have the host adapters mounted on the motherboards. In others, the cluster transport adapters are mounted on system and I/O boards, respectively.
For information on locating your cluster transport adapters, see the documentation that shipped with your network adapter and node.
-
Cable the nodes, as shown in Figure 3-1 or Figure 3-2.
You need to use a point-to-point (crossover) Ethernet cable if you are using 100BaseT or TPE ports on a node directly to ports on another node (no switch). Gigabit Ethernet uses the standard fiber cable for both point-to-point and switch configurations.

Adding Public Network Connections
Adding public network connections to a node in a cluster is no different than doing so in a non-cluster environment.
For procedures related to administering public network connections, see Sun Cluster 3.0 System Administration Guide.
How to Add Public Network Connections
For instructions on adding public network connections, see the hardware documentation that shipped with your node and public network connection devices.

To install your storage, see "Installing a StorEdge MultiPack", "Installing a StorEdge D1000", "Installing a StorEdge A5x00", or "Installing a StorEdge A3500".
Removing Public Network Connections
Caution - You must maintain at least one public network connection for each node in the cluster. The cluster is inaccessible without a public network connection.
Removing public network connections from a node in a cluster is no different than doing so in a non-cluster environment. For procedures related to administering public network connections, see Sun Cluster 3.0 System Administration Guide.
How to Remove Public Network Connections
For instructions on removing public network connections, see the hardware documentation that shipped with your node and public network connection devices.
