Upgrade your plug-in packages

The plug-in packages are distributed as part of the SnapCenter upgrade.

The upgrade procedure places your Windows, Linux, or AIX host in “maintenance” mode, which prevents the host from running any scheduled jobs.

What you will need

  • If you are a non-root user with access to the Linux machines, you should update the /etc/sudoers file with the latest checksum values before performing the upgrade operation.

  • By default SnapCenter detects JAVA_HOME from the environment. If you want to use a fixed JAVA_HOME and if you are upgrading the plug-ins on a Linux host, you should manually add the SKIP_JAVAHOME_UPDATE parameter in the spl.properties file located at /var/opt/snapcenter/spl/etc/ and set the value to TRUE.

    The value of JAVA_HOME gets updated when the plug-in is upgraded or when the SnapCenter plug-in loader (SPL) service restarts. Before upgrading or restarting the SPL, if you add the SKIP_JAVAHOME_UPDATE parameter and set the value to TRUE, the value of JAVA_HOME is not updated.

  • You should have backed up all the SnapCenter configuration files that you have modified either on the SnapCenter Server host or the plug-in host.

    Examples of SnapCenter configuration files: SnapDriveService.exe.config, SMCoreServiceHost.exe.config, and so on.

Steps

  1. In the left navigation pane, click Hosts > Managed Hosts.

  2. Upgrade the hosts by performing one of the following tasks:

    • If the Overall Status column displays “Upgrade available” for one of the hosts, click the host name and perform the following:

      1. Click More Options.

      2. Select Skip prechecks if you do not want to validate whether the host meets the requirements to upgrade the plug-in.

      3. Click Upgrade.

    • If you want to upgrade multiple hosts, select all the hosts, click more icon, and then click Upgrade > OK.

      Note All the plug-ins in the package gets selected, but only the plug-ins that were installed with the earlier version of SnapCenter are upgraded, and the remaining plug-ins are not installed. You must use the Add plug-ins option to install any new plug-in.

If you have not selected the Skip prechecks check box, the host is validated to see if it meets the requirements to install the plug-in. If the minimum requirements are not met, appropriate error or warning messages are displayed. After fixing the issue, click Upgrade.

Note If the error is related to disk space or RAM, you can update either the web.config located at C:\Program Files\NetApp\SnapCenter WebApp, or the PowerShell config files located at C:\Windows\System32\WindowsPowerShell\v1.0\Modules\SnapCenter\ to modify the default values. If the error is related to remaining parameters then you must fix the issue, and then validate the requirements again.
