PowerScale OneFS Upgrade Planning and Process Guide

PDF

Performing a parallel upgrade using the web administration interface

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

Perform the pre-upgrade steps in this guide, confirm cluster health, and resolve any compatibility issues before upgrading to the new version of OneFS.
  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. Enter the file path location of the upgrade image to install. The file path must be accessible in an /ifs directory.
  5. (Optional) In OneFS 9.2.0.0 and later, to update node firmware during the upgrade, enter the file path location of the node firmware package.
  6. In the Upgrade Type drop-down list, select Parallel Upgrade.
  7. (Optional) To skip optional pre-upgrade checks related to compatibility, select Skip optional pre-upgrade checks.
  8. (Optional) In OneFS 9.2.0.0 and later, to manage disruption to SMB client connections, follow these steps:
    1. Check Enable disruption manager
    2. (Optional) Check Wait Forever to wait for all SMB clients to disconnect from a node before upgrading.
    3. Enter the Drain time out to specify the amount of time OneFS waits for clients to manually disconnect before the node reboots and upgrades.
    4. Enter the CELOG time out to specify the amount of time OneFS waits for clients to disconnect before alerting the OneFS administrator. This allows the administrator to work with the connected clients before rebooting the node.
  9. Click Start Upgrade to begin the upgrade.
    The cluster might display several confirmation messages. Confirm each message to continue the upgrade process.
NOTE:In 9.2.0.0 and later, you can use the upgrade status screen to monitor the progress of your upgrade, view connected clients, and delay draining clients from specific nodes.
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.
