Undeploying and uninstalling InfoScale by using CLI

For a custom namespace, complete the following steps to undeploy and uninstall InfoScale.

  1. Run the following command on the bastion node to undeploy.

    oc delete -f /YAML/OpenShift/OLM/cr.yaml

    Note:

    cr.yaml must be the same that was used for deployment.

  2. Run the following command on the bastion node to delete the operator group.

    oc delete og -n infoscale-vtas infoscale-opgroup

    If InfoScale is installed in openshift-operators, run .

    oc delete og -n openshift-operators infoscale-opgroup

  3. Run the following command on the bastion node to delete subscription for the InfoScale operator.

    Note:

    Ignore this step if you have installed in openshift-operators.

    oc delete sub -n infoscale-vtas -all

  4. Run the following commands on the bastion node to delete the ClusterServiceVersion.

    • oc get csv |egrep "cert-manager|Node Feature|Infoscale|Special Resource"|awk '{print $1}'

      Use the csv_name and clusterserviceversion returned from this command in the following commands.

    • oc delete csv <csv_name> -n infoscale-vtas

      Note:

      Ignore this step if you have installed in openshift-operators.

    • oc delete clusterserviceversion <csv_name>

    Note:

    While entering the command, ensure that you do not enclose the csv_name and crd_name in angle brackets.

  5. Run the following commands on the bastion node the delete the CRDs (Custom Resource Definitions)

    • oc get crd | egrep 'cert-manager|special|info|nfd

      All CRDs are listed. Use the names of the listed CRDs in the following commands to delete the CRDs one -by-one.

    • oc delete crd <crd_name>

  6. Run the following command on the bastion node to delete the namespace. Ignore if you had installed in openshift-operators.

    oc delete ns infoscale-vtas

Note:

After uninstallation, ensure that stale InfoScale kernel modules (vxio/vxdmp/veki/vxspec/vxfs/odm/glm/gms) do not remain loaded on any of the worker nodes. Rebooting a worker node deletes all such modules.
