How to Replace an Interconnect Component

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.

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

   • 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 dynamic reconfiguration 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 dynamic reconfiguration 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 .

2. Disconnect the failed interconnect component from other cluster devices.

   For the procedure about how to disconnect cables from transport adapters, see the documentation that shipped with your host adapter and node.

3. Connect the new interconnect component to other cluster devices.

   • 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.

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