In load sharing media server installations, you can maintain continuous access to the media server services during upgrades, by upgrading one cluster server at a time. Either the Primary or Secondary server must remain in service for the cluster to remain operational. Cluster service is lost if the Primary and Secondary servers are out of service at the same time.
N+1 load sharing clusters of Avaya Aura® MS nodes are upgraded as follows:
  • For the Primary server, perform the procedure to upgrade a simplex Avaya Aura® MS.
    Wait for any alarms to clear as the server returns to service after the upgrade.
  • For each Standard server, perform the procedure to upgrade a simplex Avaya Aura® MS.
    Wait for any alarms to clear as the server returns to service after the upgrade.
  • For the Secondary server, perform the procedure to upgrade a simplex Avaya Aura® MS.
