PowerScale OneFS Upgrade Planning and Process Guide

Perform a rolling upgrade using the web administration interface

You can use the web administration interface to upgrade the version of OneFS that is running on the cluster.

1. Log in to any node in the cluster through the web administration interface with the root account.
2. Click Cluster Management > Upgrade.
3. Click Upgrade OneFS.
4. Browse to the location of the installation image that you want to install. The file path must be accessible in an /ifs directory. Then click Select.
5. In the Upgrade Type list, select Rolling Upgrade.
6. Under Nodes to Upgrade, specify an upgrade option:
   • To upgrade all the nodes in the cluster, click All nodes.
   • To upgrade specific nodes, click Specify nodes and reboot order.
     NOTE:We recommend that you upgrade all the nodes. If you upgrade some nodes, a weekly alert is sent to confirm that the upgrade is making progress. Do not leave the cluster in a partially upgraded state for a prolonged period. Some new features in the upgrade might not be available until all the nodes in the cluster have been upgraded and the upgrade is committed. Refer to the release notes for the OneFS version that you are upgrading to for information about features that require all the nodes to be upgraded.
7. If you are upgrading specific nodes, select the node or nodes in the Nodes Available for Upgrade list, and then click Add.
   The selected node or nodes are added to the Nodes Selected for Upgrade section. To arrange the nodes in the preferred restart order, click the arrows next to the nodes in the Nodes Selected for Upgrade section.

   NOTE:In OneFS 9.2.0.0 and later, the restart order is ignored. Instead, OneFS restarts any node that is ready, as long as only one node is restarting at a time. This process allows for quicker rolling upgrades.
8. Optional: To skip the pre-upgrade checks for compatibility issues, select Skip optional pre-upgrade checks.
   NOTE:It is recommended that you run the optional pre-upgrade checks. Before starting an upgrade, OneFS checks that your cluster is healthy enough to complete the upgrade process. Some of the pre-upgrade checks are mandatory, and will be performed even if you choose to skip the optional checks. All pre-upgrade checks contribute to a safer upgrade.
9. Click Start Upgrade.
   The cluster might display several confirmation messages. Confirm each message to continue the upgrade process.
