PowerScale OneFS Upgrade Planning and Process Guide
Configuration changes during rolling upgrades
You can continue to manage data and modify some cluster configurations during a rolling upgrade. For example, you can modify SMB shares and NFS exports. It is recommended that you make configuration changes from the node with the highest devid. The node with the highest devid is the last node to be upgraded and helps you avoid being disconnected during the upgrade process.
NOTE:Attempts to enable or configure settings on an upgraded node fail until the upgrade is complete. New
OneFS features and software modules are not functional until all nodes in the cluster are upgraded.
