How to Add an Interconnect Component

This procedure defines interconnect component as any one of the following components:

• Transport adapter

• Transport cable

• Transport junction (switch)

This section contains the procedure about how to add transport adapters 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.

1. Determine if you need to shut down and power off the node that is to be connected to the interconnect component you are adding.

   • 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 how to shut down a node, see Chapter 3, Shutting Down and Booting a Cluster, in Sun Cluster System Administration Guide for Solaris OS.

2. Install the interconnect component.

   • 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.

   • If you are using a PCI-SCI interconnect, see SPARC: How to Install PCI-SCI Transport Cables and Transport Junction for cabling diagrams and considerations.

   • For the procedure about how to install transport adapters or set 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 SPARC: Requirements When Using Jumbo Frames and see the Sun GigaSwift documentation for instructions.

3. If you shut down the node in Step 1, perform a reconfiguration boot to update the new Solaris device files and links. Otherwise, skip this step.
