Undeploying and uninstalling InfoScale

You can run the following command to undeploy InfoScale on your OpenShift cluster. Additionally, see Deleting Operators from a cluster to ensure a clean undeployment.

Note:

If you want to retain the disk group and re-use the Volumes you created, ensure that you note the ClusterID before undeploying and uninstalling InfoScale. You must use this ClusterID while re-installing InfoScale. Else, clean the disks before uninstalling.

  • Run the following commands on the bastion node

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

    The commands to clean up InfoScale components like the Operator, SR, and SRO are as under

    Note:

    Run these commands only after all InfoScale pods are terminated.

    oc delete -f /YAML/OpenShift/iso.yaml

    oc delete -f /YAML/OpenShift/license_cr.yaml

    oc delete -f /YAML/OpenShift/lico.yaml

    oc delete -f /YAML/OpenShift/sr.yaml

    oc delete -f /YAML/OpenShift/sro.yaml

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. When fencing is configured, certain keys are configured. Those must also be deleted after uninstallation. Run ./clearkeys.sh <Path to the first disk>, <Path to the second disk>,... to remove stale keys that might have remained.

Reconfiguring InfoScale cluster for upgrading OCP to 4.12.31

Complete the following steps to migrate InfoScale 8.0.210/8.0.220 on OCP 4.10.x or 4.11.x to OCP 4.12.31

  1. Downscale the InfoScale-PVC bound replica applications count to 0.
  2. Note the active replica count and ClusterID.
  3. Delete the InfoScale cluster resource.
  4. If the SDS pods are in a 'TERMINATING' state, run oc delete po <SDS pod name> -n infoscale-vtas --force --grace-period=0
  5. Delete license resource, licensing operator, InfoScale sds operator, special resource, and special resource operator.
  6. Delete nfd operator from infoscale-vtas, if it is present.

    Note:

    Refer to the earlier sections to know how to delete operators.

  7. If applications or PVCs are active in infoscale-vtas, delete

    • Relevant resources of NFD operator

    • Operator group for InfoScale-sds installation.

    • Old InfoScale install plans

  8. Delete infoscale-vtas, if PVCs are not active.
  9. Delete the CRDs for InfoScale, special resource, and NFD.
  10. Upgrade OpenShift to 4.12.31.
  11. Refer to the earlier sections and re-install InfoScale. Ensure that you use the same ClusterID.
  12. After the InfoScale cluster is running and PVC is in bound state, increase the replica count of the respective applications to the previously deployed replicas.
