This section provides a list of checks to be performed before initiating upgrade of NSX Advanced Load Balancer.

NSX Advanced Load Balancer supports a simple system upgrade method wherein all NSX Advanced Load Balancer Controller nodes and SE nodes are upgraded to the newer software version in one upgrade sequence. Following are the list of checks to be performed before upgrading the NSX Advanced Load Balancer:

  • Check if all the three nodes of the Controller cluster are Active.

    For more information about Controller clusters, see NSX Advanced Load Balancer Controller Cluster and Changing NSX Advanced Load Balancer Controller Cluster Configuration.

  • Check if there is adequate disk space on all the Controller nodes before the upgrade. Ideally, the disk usage must not be more than 60%. For more information, see NSX Advanced Load Balancer Controller Sizing topic in the VMware NSX Advanced Load BalancerInstallation Guide.

  • If the disk usage is more (greater than 80%), look for any core archives or packages uploaded to the Controller nodes and clear them. Core archives are under /var/lib/avi/ archives.

  • Ensure all servers are connected. Run Show serviceengine. Check if all the service engines are UP unless they are disabled. For more information, see De-activating SE topic in the VMware NSX Advanced Load BalancerMonitoring and Operability Guide. The upgrade command does a pre-check to ensure that no Service Engines are disconnected from the Controller, so we do not inadvertently finish the upgrade without these Service Engines.

  • Ensure that all the SEs are on the version required. Run show version controller and show version serviceengine.

  • Check CPU and memory of all Controllers to ensure compliance with minimum recommendations.
