Preparing Portworx to upgrade to OpenShift 4.3 using the Operator
Before you can upgrade your OpenShift environment to 4.3, you must upgrade Portworx to 2.3.5 and expose a new port range so that Portworx can continue to operate. Perform the following steps to upgrade Portworx to 2.3.5 in preparation for upgrading your OpenShift environment:
From the OpenShift console, upgrade the Portworx Operator to version 1.1.1 newer.
Upgrade Portworx to 2.3.5.
Verify that all of your nodes have upgraded to 2.3.5:
oc get storagenode -n kube-system
NAME ID STATUS VERSION AGE node-1 04904446-781b-4e12-b1ce-753a9e72dd49 Online 220.127.116.11-a5a0ba1 68s node-2 b7a9e162-3166-475f-af6b-3860a4dc2b06 Online 18.104.22.168-a5a0ba1 2m node-3 8c182888-280a-4738-abf8-3bccaadeb359 Online 22.214.171.124-a5a0ba1 3m
Open the port ranges on your cloud provider and operating system to allow traffic on ports 17001 - 17020.
Change your Portworx cluster’s start port:
oc editcommand to modify your storage cluster:
oc edit -n kube-system <storagecluster_name>
startPortvalue in your
apiVersion: core.libopenstorage.org/v1 kind: StorageCluster metadata: name: portworx namespace: kube-system spec: startPort: 17001
Once Portworx is running on 2.3.5 and you’ve changed the port range, you may upgrade OpenShift to 4.3.
