How to Remove an Interconnect Component

Language:

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

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 4.3 System Administration Guide.

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 4.3 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 4.3 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.

Determine if you need to shut down and power off the node that is connected to the interconnect component you are removing.
- 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.
- If your node has dynamic reconfiguration enabled and you are removing 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 removing a transport adapter, shut down and power off the node with the transport adapter you are removing.
  For the full procedure about shutting down a node, see Chapter 3, Shutting Down and Booting a Cluster in Oracle Solaris Cluster 4.3 System Administration Guide.

Disconnect the interconnect component from other cluster devices.
For instructions on how to disconnect cables from transport adapters, see the documentation that shipped with your host adapter and node.

Remove the interconnect component.
For instructions on how to remove the interconnect component, see the documentation that shipped with your host adapter, nodes, or switch.

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.
