Management switches connection errors

General Page

Management switches connection warnings are displayed on the IBM Fusion switches page even though the cable connections are correctly placed between the node and the management switch.

How to identify the issue
 
Follow the steps to identify the issue:
  1. Run the following commands to get the RackGen value from the kickstart.
    oc get cm -n ibm-spectrum-fusion-ns | grep kickstart
    oc get cm <kickstart-name-obtained-from-1st-command> -n ibm-spectrum-fusion-ns -o yaml | grep rackGen
     

    Example output: 

    oc get cm -n ibm-spectrum-fusion-ns | grep kickstart
kickstart-rackgen2002                               1      32d
    oc get cm kickstart-rackgen2002 -n ibm-spectrum-fusion-ns -o yaml | grep rackGen
  "rackGen": 2,
    Note: If the rackGen value is 1, then you can ignore the hotfix instructions. However, if you are still seeing warnings about connections on the switch page, check whether the cables are properly connected to the correct ports.
     

  2. If the rackGen value is 2, then log in to the OpenShift Container Platform web console.

  3. Go to Administration > CustomResourceDefinitions.

  4. Enter the text "switch" in the search box, and select the CRD Switch from the search result.

  5. Go to Instances tab, click mgmt1-<rackname>.

  6. Go to YAML tab, and check whether you see the following status in the networkPortStatus. If you see following status, then follow the resolution steps.

    networkPortStatus:
  - actualConnection: slot IMM MGMT of control-1-ru3

Resolution
Online installation
 
Follow the instructions to apply the hotfix in the online installed rack using either OpenShift Container Platform user interface or Command Line Interface (CLI):
OpenShift Container Platform user interface:
 
  1. Log in to the OpenShift Container Platform web console.
  2. Go to Operators > Installed Operators.
  3. In the Project drop-down, select ibm-spectrum-fusion-ns namespace.
  4. Click the IBM Storage Fusion installed operator that contains the CSV for the compute operator image to be patched.
  5. Click YAML tab.
     It opens a YAML editor screen.

  6. In the YAML editor screen, search for the label control-plane: isf-network-operator.

  7. In the control-plane: isf-network-operator label, scroll down to the image field, and replace the value with the following image.

    cp.icr.io/cp/fusion-hci/isf-network-operator@sha256:f5d8ae19c68bb2773a92fe89ac70a48f2037f46f2347df187b03b92381914003

Command Line Interface (CLI):
 
  1. Log in to the cluster using oc login command.

  2. Run the following command to get the CSV.
    oc get csv -n ibm-spectrum-fusion-ns

  3. Choose the correct IBM Fusion CSV to patch it with a new network operator image using the following command.
    oc edit csv <ibm-fusion-name> -n ibm-spectrum-fusion-ns

  4. Enter the text /control-plane: isf-network-operator to find the occurrence.

  5. In the control-plane: isf-network-operator label, scroll down to the image field, and replace the value with the following image.

    cp.icr.io/cp/fusion-hci/isf-network-operator@sha256:f5d8ae19c68bb2773a92fe89ac70a48f2037f46f2347df187b03b92381914003
