PowerScale OneFS Upgrade Planning and Process Guide
Roll back an upgrade using the CLI
Rolling back stops an upgrade and returns the cluster to the previous committed version of OneFS.
NOTE:The rollback process must restart all the upgraded nodes simultaneously. This will temporarily disrupt cluster services and data availability.
Command-Line Interface instructions:
- Open a secure shell (SSH) connection on the lowest-numbered node in the cluster and log in with the root account.
-
To roll back the upgrade, run the following command:
isi upgrade cluster rollback
