Securing the Cluster Before Upgrading
If the cluster to be upgraded is nonsecure, you must secure it before upgrading.
If you used manual steps to install the cluster, see Getting Started with HPE Ezmeral Data Fabric Security.
See Enabling Security on a Configured Cluster to enable security for non-secure clusters.
If you used the Installer to install the cluster, and you want to add security, see Using the Enable Secure Cluster Option.
