Installing Operating System Updates on Linux ROBO

Operating system (OS) updates can be installed on the Linux ROBO node to ensure that the OS has the most recent updates.

Before You Begin

  • The CommServe and Linux ROBO node must be in Platform Release 11.32.63(or later).

    Verify the version in the clients associated with the CommServe server and HyperScale nodes before upgrading the OS. For more information, see Viewing the Service Pack Details for One or More Clients.

  • The update process installs the updates provided by Red Hat for the OS.

    The process does not update other RPMs that may have been manually installed on the nodes, including other third-party RPMs that may have been manually installed on the nodes.

Procedure

  1. Verify that the remote cache is set up on the Linux ROBO node using the following steps:

    1. From the navigation pane, go to Manage > System > 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 Schedule Job Download Software (2).

      The Download/copy software dialog box appears.

    4. In Remote caches to sync, expand Servers and make sure the Linux ROBO node is listed. (This is automatically created when you configure the storage pool.)

    5. Click Cancel to close the dialog box.

  2. Download the latest updates and populate the remote cache as follows:

    1. From the navigation pane, go to Manage > System > 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 Right arrow.

      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 Linux ROBO 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.

  3. Set the MediaAgents associated with the node in the Maintenance mode. For more information, see Setting the MediaAgent on Maintenance Mode.

  4. On the system console (for example, using KVM, not SSH) of the node on which the remote cache is configured, press Ctrl+Alt+F2 to get to login prompt, log on to the node, and then navigate to the following folder:

    /opt/commvault/MediaAgent

  5. Update the operating system binaries using following command:

    # ./cvupgradeos.py -upgrade_os_only
    The installation process will start. The progress of the installation is displayed. (The sequence is also logged in /var/log/commvault/Log_Files/cvupgradeos.log.)

    Note the following:

    • 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.

  6. Once the last node has rebooted, log back into the node and navigate to the following folder:

    /opt/commvault/MediaAgent

  7. Once the installation is completed, check the status of the installation using the following command:

    # ./cvupgradeos.py -status

  8. If there is a failure, investigate the reason for the failure in /var/log/commvault/Log_Files/cvupgradeos.log. Correct the issue causing the failure and then rerun cvupgradeos.py to install the updates in the failed node.

  9. Using the Command Center, remove the MediaAgents associated with the nodes from Maintenance mode. For more information, see Setting the MediaAgent on Maintenance Mode.

Result

  • The updates will be installed in the Linux ROBO node.

  • 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.
