PowerScale OneFS Upgrade Planning and Process Guide
Perform a simultaneous upgrade using the CLI
You can use the command-line interface to upgrade the version of OneFS that is running on the cluster.
- Open a secure shell (SSH) connection on the lowest-numbered node in the cluster and log in with the root account.
-
To perform a simultaneous upgrade, run the following command, where
<install-image-path> is the file path of the upgrade install image. The file path must be accessible in an
/ifs directory.
isi upgrade cluster start --simultaneous <install-image-path>
NOTE:The isi upgrade cluster command runs asynchronously. The command does not run the entire upgrade process; instead, it sets up the upgrade process, which nodes take turns controlling. For this reason, the command returns quickly. To view the progress of the upgrade, use the isi upgrade view command or the web administration interface.
After the upgrade, a number of upgrade-related jobs may continue to run on the cluster for some time. During this time, the cluster is accessible, but you might experience a decrease in cluster performance. After the jobs complete, performance will return to normal. At this stage, the upgrade is complete, but is not committed. You can still roll back to the previous version of
OneFS. Some new features in the upgrade might not be available until the upgrade is committed.
