PowerScale OneFS Upgrade Planning and Process Guide
Completing a parallel upgrade of OneFS
If you perform a parallel upgrade, subsets of nodes within the
OneFS cluster are restarted in an undetermined order. During a parallel upgrade, client connections to the restarting subset of nodes are disconnected, but other subsets of nodes remain available for client connection.
NOTE:The parallel upgrade feature is available in
OneFS version 8.2.2 and later. Upgrades where the source cluster is on
OneFS 8.2.1 or earlier must use the rolling or simultaneous option.
