Interconnect components include the following components:
Transport adapter
Transport cable
Transport junction (switch)
This procedure defines interconnect component as any one of the following components:
Transport adapter
Transport cable
Transport junction (switch)
This section contains the procedure for adding interconnect components to nodes in a running cluster.
Before You Begin
This procedure relies on the following prerequisites and assumptions:
Your cluster is operational and all nodes are powered on.
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.
If you are adding a transport junction, you do not need to shut down and power off the node. Proceed to Step 2.
If you are adding a transport cable, you do not need to shut down and power off the node. Proceed to Step 2.
If your node has Dynamic Reconfiguration (DR) enabled and you are replacing a transport adapter, you do not need to shut down and power off the node. Proceed to Step 2.
If your node does not have DR enabled and you are adding a transport adapter, shut down and power off the node with the transport adapter you are adding.
For the full procedure about shutting down a node, see Chapter 3, Shutting Down and Booting a Cluster, in Oracle Solaris Cluster System Administration Guide.
If you are using an Ethernet or InfiniBand interconnect, see How to Install Ethernet or InfiniBand Transport Cables and Transport Junctions for cabling diagrams and considerations.
For the procedure about installing transport adapters or setting transport adapter DIP switches, see the documentation that shipped with your host adapter and node hardware.
If your interconnect uses jumbo frames, review the requirements in Requirements When Using Jumbo Frames and see the Sun GigaSwift documentation for instructions.

This procedure defines interconnect component as any one of the following components:
Transport adapter
Transport cable
Transport junction (switch)
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. You can check the status of the interconnect with the clinterconnect statuscommand. For more details about checking the status of the cluster interconnect, see How to Check the Status of the Cluster Interconnect in Oracle Solaris Cluster System Administration Guide. |
You might perform this procedure in the following scenarios:
You need to replace a failed transport adapter.
You need to replace a failed transport cable.
You need to replace a failed transport junction.
For conceptual information about transport adapters, transport cables, and transport junction, see Cluster Interconnect in Oracle Solaris Cluster Concepts Guide.
Before You Begin
This procedure relies on the following prerequisites and assumptions.
Your cluster has another functional interconnect path to maintain cluster communications while you perform this procedure.
Your cluster is operational and all nodes are powered on.
Identify the interconnect component that you want to replace. Remove that interconnect component from the cluster configuration by using the procedure in How to Remove Cluster Transport Cables, Transport Adapters, and Transport Switches in Oracle Solaris Cluster System Administration Guide.
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.
If you are replacing a transport junction, you do not need to shut down and power off the node. Proceed to Step 2.
If you are replacing a transport cable, you do not need to shut down and power off the node. Proceed to Step 2.
If your node has DR enabled and you are replacing a transport adapter, you do not need to shut down and power off the node. Proceed to Step 2.
If your node does not have DR enabled and you are replacing a transport adapter, shut down and power off the node with the transport adapter you are replacing.
For the full procedure about how to shut down a node, see Chapter 3, Shutting Down and Booting a Cluster, in Oracle Solaris Cluster System Administration Guide.
For the procedure about how to disconnect cables from transport adapters, see the documentation that shipped with your host adapter and node.
If you are replacing an Ethernet or InfiniBand interconnect, see How to Install Ethernet or InfiniBand Transport Cables and Transport Junctions for cabling diagrams and considerations.
If your interconnect uses jumbo frames, review the requirements in Requirements When Using Jumbo Frames and see the Sun GigaSwift documentation for instructions. Refer to ce Sun Ethernet Driver Considerations for details of how to edit the ce.conf file according to the GigaSwift documentation's instructions.

You might perform this procedure in the following scenarios:
You need to remove an unused transport adapter.
You need to remove an unused transport cable.
You need to remove an unused transport junction.
You want to migrate from a two–node cluster that uses switches to a point-to-point configuration.
For conceptual information about transport adapters, transport cables, and transport junctions, see Cluster Interconnect in Oracle Solaris Cluster Concepts Guide.
Before You Begin
This procedure assumes that your cluster is operational and all nodes are powered on.
Before you perform this procedure, perform the following tasks:
If you are migrating from a two–node cluster that uses switches to a point-to-point configuration, install a crossover cable before you remove a switch.
Identify the interconnect component that you want to remove. Remove that interconnect component from the cluster configuration by using the procedure in How to Remove Cluster Transport Cables, Transport Adapters, and Transport Switches in Oracle Solaris Cluster System Administration Guide.
If you plan to use virtual local area networks (VLANs) in your cluster interconnect, configure the transport junction. For more information about how configure VLANs, see Configuring VLANs as Private Interconnect Networks.
If you are removing a transport junction you, do not need to shut down and power off the node. Proceed to Step 2.
If you are removing a transport cable you, do not need to shut down and power off the node. Proceed to Step 2.

You might perform this procedure in the following scenarios:
You want to use firmware bug fixes.
You want to use new firmware features.
Use this procedure to update transport adapter firmware.
Before You Begin
To perform this procedure, become superuser or assume a role that provides solaris.cluster.read and solaris.cluster.modify role-based access control (RBAC) authorization.
Use the following command:
# clresourcegroup status -n nodename # cldevicegroup status -n nodename
Note the device groups, the resource groups, and the node list for the resource groups. You will need this information to restore the cluster to its original configuration in Step 4.
# clnode evacuate fromnode
This process might require you to boot into noncluster mode. If it does, boot the node into cluster mode before proceeding. For the procedure about how to upgrade your transport adapter firmware, see the patch documentation.
Perform the following step for each device group you want to return to the original node.
# cldevicegroup switch -n nodename devicegroup1[ devicegroup2 …]
The node to which you are restoring device groups.
The device group or groups that you are restoring to the node.
In these commands, devicegroup is one or more device groups that are returned to the node.
Perform the following step for each resource group you want to return to the original node.
# clresourcegroup switch -n nodename resourcegroup1[ resourcegroup2 …]
For failover resource groups, the node to which the groups are returned. For scalable resource groups, the node list to which the groups are returned.
The resource group or groups that you are returning to the node or nodes.
The resource group that is returned to the node or nodes.
