Interconnect components include the following components:

How to Add an Interconnect Component

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

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:

  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 shutting down a node, see Chapter 3, Shutting Down and Booting a Cluster, in Oracle Solaris Cluster System Administration Guide.

  2. Install the interconnect component.
  3. 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.

How to Replace 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 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:

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.

  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 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.

  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.
  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.

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:

  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 shutting down a node, see Chapter 3, Shutting Down and Booting a Cluster, in Oracle Solaris Cluster System Administration Guide.

  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 Oracle Solaris device files and links. Otherwise, skip this step.

How to Upgrade Transport Adapter Firmware

You might perform this procedure in the following scenarios:

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.

  1. Determine the resource groups and the device groups that are online on the node. This node is the node on which you are upgrading transport adapter firmware.

    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.

  2. Migrate the resource groups and device groups off the node on which you plan to upgrade the firmware.
    # clnode evacuate fromnode
  3. Perform the firmware upgrade.

    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.

  4. If you moved device groups off their original node in Step 2, restore the device groups that you identified in Step 1 to their original node.

    Perform the following step for each device group you want to return to the original node.

    # cldevicegroup switch -n nodename devicegroup1[ devicegroup2 …]
    -n nodename

    The node to which you are restoring device groups.

    devicegroup1[ devicegroup2 …]

    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.

  5. If you moved resource groups off their original node in Step 2 restore the resource groups that you identified in Step 1 to their original node.

    Perform the following step for each resource group you want to return to the original node.

    # clresourcegroup switch -n nodename resourcegroup1[ resourcegroup2 …]
    nodename

    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.

    resourcegroup1[ resourcegroup2 …]

    The resource group or groups that you are returning to the node or nodes.

    resourcegroup

    The resource group that is returned to the node or nodes.
