Adding Cluster Transport Adapters

This section provides the procedure for adding cluster transport adapters to a running cluster.

For conceptual information on cluster transport adapters, see the Sun Cluster 3.0 Concepts document.

How to Add Cluster Transport Adapters

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

   # 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.

2. Power off the node.

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

3. Install the cluster transport adapter.

   This procedure is the same as the procedure in a non-cluster environment. For the procedure on installing network adapters, see the documentation that shipped with your network 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 U1 System Administration Guide.

Where to Go From Here

If the cluster transport adapter you add appears in the Sun Cluster software configuration, and you want to reconfigure Sun Cluster with the new cluster transport adapter, see the Sun Cluster 3.0 U1 System Administration Guide.

Replacing Cluster Transport Adapters

This section provides the procedure for replacing a failed cluster transport adapter in a running cluster.

For conceptual information on cluster transport adapters, see the Sun Cluster 3.0 Concepts document.

How to Replace Cluster Transport Adapters

---

Caution -

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

   # 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.

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 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.

4. Replace the cluster transport adapter.

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

Where to Go From Here

If 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 the Sun Cluster 3.0 U1 System Administration Guide.

Removing Cluster Transport Adapters

This section provides the procedure for removing an unused cluster transport adapter from a running cluster.

For conceptual information on cluster transport adapters, see the Sun Cluster 3.0 Concepts document.

How to Remove Cluster Transport Adapters

Caution -

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.

Adding Public Network Adapters

Physically adding public network adapters to a node in a cluster is no different from adding public network adapters in a non-cluster environment.

How to Add Public Network Adapters

For the procedure on physically adding public network adapters, see the hardware documentation that shipped with your node and public network adapters.

To add this public network adapter to a NAFO group, see the Sun Cluster 3.0 U1 System Administration Guide.

Replacing Public Network Adapters

Physically replacing public network adapters to a node in a cluster is no different from replacing public network adapters in a non-cluster environment.

How to Replace Public Network Adapters

For the procedure on physically replacing public network adapters, see the hardware documentation that shipped with your node and public network adapters.

Where to Go From Here

To add this public network adapter to a NAFO group, see the Sun Cluster 3.0 U1 System Administration Guide.

Removing Public Network Adapters

---

Caution -

You must maintain at least one public network connection for each node in the cluster. You cannot access the cluster without a public network connection.

Removing public network adapters from a node in a cluster is no different from removing public network adapters in a non-cluster environment. For procedures related to administering public network connections, see the Sun Cluster 3.0 U1 System Administration Guide.

How to Remove Public Network Adapters

For the procedure on removing public network adapters, see the hardware documentation that shipped with your node and public network adapters.
