Triggering the Rolling Software Upgrade

The SMF utilizes the SMI Cluster Manager to perform a rolling software update. To update SMF using SMI Cluster Manager, use the following configurations:

Important

Before you begin, ensure that SMF is up and running with the latest version of the software.

  1. Log in to SMI Cluster Manager Ops Center.

  2. Download the latest TAR ball from the URL using the software-packages download url command.

    NOTES:

    software-packages download url : Specify the software packages to be downloaded through HTTP or HTTPS.

  3. Verify whether the TAR balls are loaded.

    Example:

    SMI Cluster Manager# software-packages list 
    [ smf-2019-08-21 ] 
    [ sample ] 
    

    NOTES:

    software-packages list : Specify the list of available software packages.

  4. Update the product repository URL with the latest version of the product chart.

    Note

    If the repository URL contains multiple versions, the Ops Center automatically selects the latest version.

    configure
      cluster cluster_name
       ops-centers app_name smf_instance_name
            repository url
             exit
           exit 

    Example:

    SMI Cluster Manager# config 
    SMI Cluster Manager(config)# clusters test2 
    SMI Cluster Manager(config-clusters-test2)# ops-centers smf data 
    SMI Cluster Manager(config-ops-centers-smf/data)# repository <url> 
    SMI Cluster Manager(config-ops-centers-smf/data)# exit 
    SMI Cluster Manager(config-clusters-test2)# exit 
    

    NOTES:

    clusters cluster_name : Specify the information about the nodes to be deployed. cluster_name is the name of the cluster.

  5. Run the following command to update to the latest version of the product chart.

    clusters cluster_name actions sync run 

    Example:

    SMI Cluster Manager# clusters test2 actions sync run

NOTES:

  • ops-centers app_name instance_name : Specifies the product Ops Center and instance. app_name is the application name. instance_name is the name of the instance.

  • repository url : Specify the local registry URL for downloading the charts.

  • actions : Specify the actions performed on the cluster.

  • sync run : Trigger the cluster synchronization.

Important
  • The cluster synchronization updates the SMF Ops Center, which in turn updates the application pods (through helm sync command) one at a time automatically.

  • When you trigger rolling upgrade on a specific pod, the SMF avoids routing new calls to that pod.

  • The SMF honors in-progress call by waiting for 30 seconds before restarting the pod where rolling upgrade is initiated. Also, the SMF establishes all the in-progress calls completely within 30 seconds during the upgrade period (maximum call-setup time is 10 seconds).
