Sun Cluster 3.0-3.1 Hardware Administration Manual for Solaris OS

ProcedureHow to Remove an Interconnect Component

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


Caution – 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 command scstat -W. For more details about checking the status of the cluster interconnect, see How to Check the Status of the Cluster Interconnect in Sun Cluster System Administration Guide for Solaris OS.


You might perform this procedure in the following scenarios:

For conceptual information about transport adapters, transport cables, and transport junctions, see Cluster Interconnect in Sun Cluster Concepts Guide for Solaris OS.

Before You Begin

This procedure relies on the following prerequisites and assumptions:

  1. 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 DR 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 DR 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 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. Disconnect the 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. Remove the interconnect component.

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

  4. 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.
