Changing required node settings (Upgrading from Version 3.5 to Version 4.6)

Important: IBM Cloud Pak® for Data Version 4.6 will reach end of support (EOS) on 31 July, 2025. For more information, see the Discontinuance of service announcement for IBM Cloud Pak for Data Version 4.X.

Upgrade to IBM Software Hub Version 5.1 before IBM Cloud Pak for Data Version 4.6 reaches end of support. For more information, see Upgrading IBM Software Hub in the IBM Software Hub Version 5.1 documentation.

Some services that run on IBM Cloud Pak for Data require specific settings on the nodes in the cluster. To ensure that the cluster has the required settings for these services, an operating system administrator with root privileges must review and adjust the settings on the appropriate nodes in the cluster.

Red Hat® OpenShift® Container Platform Version 3.11: If you upgraded from Red Hat OpenShift Container Platform Version 3.11, you must reapply these settings to your cluster.
Red Hat OpenShift Container Platform Version 4.5: If you upgraded from Red Hat OpenShift Container Platform Version 4.5, verify that the appropriate settings are already applied to your cluster.
Red Hat OpenShift Container Platform Version 4.6: If you upgraded from Red Hat OpenShift Container Platform Version 4.6, verify that the appropriate settings are already applied to your cluster.
Red Hat OpenShift Container Platform Version 4.8: If you are running Red Hat OpenShift Container Platform Version 4.8, verify that the appropriate settings are already applied to your cluster.
