Installing Operating System Updates on HyperScale X

Commvault verifies and releases the updates available for the HyperScale platform stack periodically. You can install the OS and CVFS updates on the HyperScale nodes to ensure that the node has the most recent updates.

You can install the OS updates from the Metallic console. The update process installs the updates provided by Red Hat for the OS and the Commvault File System (CVFS) RPMs. The process does not update any other third-party RPMs that may have been manually installed on the nodes.

The CVFS 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

• Verify that the Server Gateway and HyperScale nodes are on the same release version.

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

• Verify that the Commvault Cloud services and the CVFS services are running. To verify, run the following commands:

  • # commvault list

    Verify that all services are up and running

  • # /usr/local/hedvig/scripts/showmembers.exp

    Verify that the output displays UNREACHABLE MEMBERS:0

Procedure

1. From the navigation pane, go to Manage > Server groups.

   The Server groups page appears.

2. In the row for the smart 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.

3. Select the Install operating system updates check box.

   The installation also updates the CVFS binaries if any.

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 upgrade job to ensure that the OS software is successfully updated. For more information, see Viewing Jobs.

   Note

   the following:

   • The updates will be installed sequentially on each HyperScale node available in the current cluster.

   • At the end of update installation, each node will be rebooted before moving on to the next node.

   • The remote cache node (or the node from which the OS updates are installed) will be the last node to reboot. The upgrade will automatically resume after the reboot but may take some time to complete the post upgrade operations in this node.

   • The upgrade for each node takes up to 60-90 minutes.

Result

• The updates will be installed in all the HyperScale nodes.

• If the OS version is upgraded, you can verify the OS version as follows:

  1. From the navigation pane, go to Manage > Server groups.

     The Server groups page appears.

  2. The server name, OS version, and other details are displayed for each server in the server group.

What to Do Next

For nodes with RHEL7.9 Operating System, you must update or reinstall the megaraid_sas and smartpqi drivers after installing the OS updates. These drivers are kernel modules and get installed only in the running kernel version.
