Upgrade Red Hat OpenShift Virtualization

Upgrade of Red Hat® OpenShift® Virtualization on IBM Storage Fusion HCI System is done based on Red Hat guidelines.

For the procedure to upgrade Red Hat OpenShift Virtualization, see Red Hat documentation on Updating OpenShift Virtualization.

Important: If you created virtual machines on the OpenShift Container Platform cluster by using the OpenShift virtualization, then the PVCs of the live migration VMs use Read Write Many (RWX) access modes. Otherwise, these VMs block drain during roll-outs, and you must manually force-drain the nodes and delete the VMs.
