IBM Fusion 2.11.0 network issues: Stale SSH Connections Not Terminating on High-Speed Switches

General Page

On high-speed switches, some of the SSH sessions that are initiated by IBM Fusion automation does not close as expected, resulting in inactive or stale connections. Over time, these connections can accumulate and exhaust system resources, potentially affecting switch performance and causing operational issues.


Note: This is a cumulative patch and contains fix from the hotfix.

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 network 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@sha256:53068ef2e365ad94f89be531a0cd13210b77e0b22698756b57f4653b72bad84d

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@sha256:53068ef2e365ad94f89be531a0cd13210b77e0b22698756b57f4653b72bad84d


Offline installation 
 

 
Follow the instructions to apply the hotfix in the offline installed rack: 
 
  1. Run the following commands to export the variables. 
    export LOCAL_ISF_REGISTRY="<Your enterprise registry host>:<port>"
    export LOCAL_ISF_REPOSITORY="<Your image path>"
    export TARGET_PATH="$LOCAL_ISF_REGISTRY/$LOCAL_ISF_REPOSITORY"
    echo "$TARGET_PATH"

  2. Log in to the IBM Entitled Container Registry by using the IBM entitlement key: 
    docker login cp.icr.io -u cp -p <your entitlement key>

  3. Run the command to log in to the docker registry with your enterprise registry credentials. 
    docker login $LOCAL_ISF_REGISTRY -u <your enterprise registry username> -p <your enterprise registrty password>

  4. From the mirroring host, run the following commands to copy the below image to the artifactory. 
    skopeo copy --insecure-policy --preserve-digests --all docker://cp.icr.io/cp/fusion-hci/isf-network-operator@sha256:53068ef2e365ad94f89be531a0cd13210b77e0b22698756b57f4653b72bad84d docker://$TARGET_PATH/cp/fusion-hci/isf-network-operator@sha256:53068ef2e365ad94f89be531a0cd13210b77e0b22698756b57f4653b72bad84d
