ProcedureHow to Replace a Node-to-Switch Component in a Cluster Without Multipathing

Steps
  1. Check if the physical data path failed.

    If no, proceed to Step 2.

    If yes:

    1. Replace the component.

      Refer to your hardware documentation for any component-specific instructions.

    2. Fix the volume manager error that was caused by the failed data path.

    3. (Optional) If necessary, return resource groups and device groups to this node.

    You have completed this procedure.

  2. Determine the resource groups and device groups that are running on Node A.


    # scstat
    
  3. Move all resource groups and device groups to another node.


    # scswitch -s -h from-node
    
  4. Replace the node-to-switch component.

    Refer to your hardware documentation for any component-specific instructions.

  5. (Optional) If necessary, return the resource groups and device groups that you identified in Step 2 to Node A.


    # scswitch -z -g resource-group -h nodename
    # swswitch -z -D device-group -h nodename
