Installing an update

Last Updated : Apr 01, 2022 |

About this task

Perform the following procedure to update the media server with the latest software release.

Before applying media server updates, ensure that you:

Upload an update by using the Uploading media server updates task. You can upload an update prior to the scheduled maintenance time for installing an update, to avoid delays during the maintenance time.
If both system layer and application layer updates exist, upload both, starting with the system layer update followed by the application layer update, before installing.
Back up the system. In case of unforeseen problems during the update installation, you can use the backup to restore the system to the current configuration.
Apply the updates to one node at a time in a cluster configuration, while the other nodes in the cluster maintain service. For High Availability clusters, see Managing media server changes for 1+1 High Availability clusters.
Perform the installation during scheduled maintenance.

To prevent new sessions from starting on the system, navigate to EM > System Status > Element Status and select More Actions > Pending Lock.
Click Confirm.
Check for active sessions on the server by navigating to EM > System Status > Monitoring > Active Sessions.

Wait for the active sessions to end. The media server automatically changes to the Locked state after all the sessions have ended.

Perform the following steps if you want to continue before the active sessions end:
1. Manually lock Avaya Aura® MS, by navigating to EM > System Status > Element Status and clicking More Actions > Lock. Locking the media server also ends any remaining sessions.
2. Click Confirm.
To install the uploaded updates, navigate to EM > Tools > Manage Software > Updates and click Install Updates...
Click Confirm.

The browser shows a progress spinner while the update is installed.

The update is complete when you can log in to EM.
Navigate to EM > Tools > Manage Software > History.
Verify that the expected versions are displayed.
Use the chevron buttons () to expand the details about each update.
Verify that each listed update component indicates (Installed).
Select EM > System Status > Element Status > More Actions > Unlock.
Click Confirm.
Check for any service-impacting alarms and perform an appropriate test of the system.

For example, place a call to the application.
