How to Remove Transport Adapters
This section contains the procedure about how to remove an unused transport adapter from a node in a running cluster. For conceptual information on transport adapters, see your Sun Cluster concepts documentation.
Caution - You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster does not function without a working cluster interconnect.
Verify that the transport adapter that you want to remove is not configured in the Sun Cluster configuration.
If the transport adapter that you want to remove appears in the Sun Cluster configuration, remove the transport adapter from the Sun Cluster configuration. To remove a transport path, follow the procedures in your Sun Cluster system administration documentation before going to Step 2.
If the transport adapter that you want to remove does not appear in the Sun Cluster configuration, go to Step 2.
Shut down the node that contains the transport adapter that you want to remove.
For the procedure about how to shut down a node, see your Sun Cluster system administration documentation.
Power off the node.
For the procedure about how to power off a node, see the documentation that shipped with your node.
Disconnect the transport cables from the transport adapter you want to remove.
For the procedure about how to disconnect cables from transport adapters, see the documentation that shipped with your host adapter and node.
Remove the transport adapter.
For the procedure about how to remove transport adapters, see the documentation that shipped with your host adapter and node.
Perform a reconfiguration boot to create the new Solaris device files and links.
How to Upgrade Transport Adapter Firmware
Use this procedure to update transport adapter firmware.
Determine the resource groups and the device groups that are running on the node. This node is the node on which you are upgrading transport adapter firmware.
# scstat
Migrate the resource groups and device groups off the node that you plan to upgrade the firmware on.
# scswitch -S -h from-node
Perform the firmware upgrade.
For the procedure about how to upgrade your transport adapter firmware, see the patch documentation.
Return the resource groups and device groups to their original node.
# scswitch -z -g resource-group -h nodename # scswitch -z -D device-group -h nodename
How to Add Transport Cables and Transport Junctions
This section contains the procedure about how to add transport cables, transport junctions (switches), or transport cables and transport junctions in a running cluster.
If you plan to use virtual local area networks (VLANs) in your cluster interconnect, configure the transport junction. For more information, see the documentation that shipped with your hardware.
For more information about how configure VLANs, see Configuring VLANs as Private Interconnect Networks.
Shut down the node that is to be connected to the new transport cable, transport junction, or transport cable and transport junction.
For the procedure about how to shut down a node, see your Sun Cluster system administration documentation.
Install the transport cable, transport junction, or transport cable and transport junction.
If you are using an Ethernet interconnect, see How to Install Ethernet Transport Cables and Transport Junctions for cabling diagrams and considerations.
If you are using a PCI-SCI interconnect, see How to Install PCI-SCI Transport Cables and Transport Junction for cabling diagrams and considerations.
Perform a reconfiguration boot to create the new Solaris device files and links.

After you add your interconnect hardware, you might want to reconfigure Sun Cluster software with the new interconnect components. If you want to reconfigure Sun Cluster software with the new interconnect components, see your Sun Cluster system administration documentation.
How to Replace Transport Cables and Transport Junctions
This section contains the procedure about how to replace failed transport cable, transport junction (switch), or transport cable and transport junction in a running cluster.
If Virtual Local Area Networks (VLANs) are configured, more than one cluster might be impacted by removing a transport junction. Ensure that all clusters are prepared for the removal of a transport junction. Also, record the configuration information of the transport junction you plan to replace and configure the new transport junction accordingly.
For more information about how to configure VLANs, see Configuring VLANs as Private Interconnect Networks.
Caution - You must maintain at least one cluster interconnect between the nodes of a cluster. The cluster does not function without a working cluster interconnect.
Shut down the node that is connected to the transport cable, transport junction, or transport cable and transport junction that you are replacing.
For the procedure about how to shut down a node, see your Sun Cluster system administration documentation.
Disconnect the failed transport cable and transport junction from the other devices.
For the procedure about how to disconnect cables from transport adapters, see the documentation that shipped with your host adapter and node.
Connect the new transport cable, transport junction, or transport cable and transport junction to the other cluster devices.
If you are replacing an Ethernet interconnect, see How to Install Ethernet Transport Cables and Transport Junctions for cabling diagrams and considerations.
If you are replacing a PCI-SCI interconnect, see How to Install PCI-SCI Transport Cables and Transport Junction for cabling diagrams and considerations.
Perform a reconfiguration boot to create the new Solaris device files and links.

After you replace your interconnect hardware, you might want to reconfigure Sun Cluster software with the new interconnect components. If you want to reconfigure Sun Cluster software with the new interconnect components, see your Sun Cluster system administration documentation.
