Validate Management Network Cabling

This page is designed to be a guide on how all nodes in a Shasta system are wired to the management network.

The Shasta Cabling Diagram (SHCD) for this system describes how the cables connect the nodes to the management network switches and the connections between the different types of management network switches. Having SHCD data which matches how the physical system is cabled will be needed later when preparing the hmn_connections.json file from the SHCD as part of Prepare Configuration Payload procedure and later when doing the Configure Management Network Switches procedure.

  • Open the SHCD
  • Look at the Device Diagrams Tab.
    • There you will see what type of hardware is on the system.
    • Take note of the hardware.
  • Look at the 25G_10G or 40G_10G tab, this will depend on the SHCD.

    • Look at this part of the page. The source is either a node or a switch. The destination is usually a switch. The source label info and destination label info indicate the component name (xname) and the port on that component to which the cable is connected. For example, x3000u01s1-j1, means the device in cabinet x3000 at location u01 within the cabinet and in slot s1 with port j1. The physical cable connecting source to destination should be labelled with source label info and destination label info.

      See Component Names (xnames).

    • Based on the vendor of the nodes and the name in the first column we can determine how it is supposed to be cabled.

    • We can use mn01 as an example. This is a master node, and in the device diagrams tab it is identified as an HPE DL325 node.

    • Once you have those two pieces of information you can use the Cable Management Network Servers for all nodes listed on the SHCD.

      • UANs and Application Nodes
      • Worker nodes
      • Master nodes
      • Storage nodes
