# Installing CVFS Updates on HyperScale Nodes

You can upgrade the Commvault File System (CVFS) packages from an older version to the latest version on Commvault Grid Appliance nodes.

Updates can be installed in a disruptive (quick upgrade) or non-disruptive (rolling upgrade) mode. In a disruptive mode, the updates are installed on all the nodes at the same time so that the upgrade process is completed quickly. In a non-disruptive mode, the updates are installed one node at a time. When updates are installed on one node, you can continue to run backup and restore operations on the other nodes uninterrupted. By default, the updates are installed using the Quick upgrade mode.

## Before You Begin

Review the following:

- Verify that the CommServe and HyperScale nodes have Commvault platform release 2023E or later installed. The CommServe and the nodes must be on the same release version.

- Verify that a smart server group with all the hyperscale nodes in the cluster is available.

  Note

  When you upgrade the CommServe to Commvault platform release 2023E, a smart server group with all the nodes is created automatically. In new installations, the smart server group is created automatically when you configure the storage pool during the installation.

- Verify that the remote cache is setup on one of the nodes in the existing storage pool. (By default the remote cache will be configured in one of the nodes, when a storage pool is configured. It is important to verify and confirm the availability of the remote cache in one of the nodes in the existing storage pool.)

  For more information, see Setting Up a Remote Cache on a Client Computer.

## Procedure

1. Download the latest updates and populate the remote cache using the following steps:

   1. From the Command Center navigation pane, go to Manage > Maintenance.

      The Maintenance page appears.

   2. Click Download/copy software.

      The Download/copy software section appears, showing the current feature release, the latest available feature release, and the last job that was run.

   3. Click Run job .

      The Download/copy software dialog box appears.

   4. Select Download software using Internet or Local Copy, depending on your environment.

   5. In Download installation media, select the available feature release or maintenance release installation files that you want to download.

   6. In Operating system options, select the Unix check box, and then select Linux x86_64 from the drop-down list.

      Note

      The latest OS updates will be downloaded, irrespective of the selected option.

   7. In Remote caches to sync, select the HyperScale node in which the remote cache is configured.

   8. Click Download.

   Monitor the progress of the download job to ensure that the software is successfully downloaded and synchronized. For more information, see Viewing Jobs.

2. From the Command Center navigation pane, go to Manage > Infrastructure > Server groups.

   The Server groups page appears.

3. In the row for the server group that contains the hyperscale nodes that you want to update, click the action button , and then select Upgrade software.

   The Confirm software upgrade dialog box appears. The Install storage updates check box is selected by default.

4. To install the updates in a non-disruptive mode, click Rolling upgrade (non-disruptive).

   Non-disruptive mode prevents the nodes from going into maintenance mode and as a result the operational status, especially for restore operations, will be uninterrupted.

5. Select the Reboot if required check box.

6. Click Yes.

   Monitor the progress of the CVFS upgrade job. For more information, see Viewing Jobs.
