Note Avaya Aura System Platform High Availability does not support:
IPv6 and cannot be configured with IPv6 addresses.
Customer provided servers.
Important When both the primary and secondary servers in a High Availability (HA) configuration require a System Platform upgrade, use the Web Console to accomplish the platform upgrade on each server independently. In addition, the following are key provisions of the platform upgrade process for High Availability deployments with System Platform 6.2 (or later):
Regardless of your existing or planned System Platform High Availability deployment scenario, complete all platform upgrade prerequisites for both the primary and secondary servers before proceeding with the two independent platform upgrades.
If the primary and secondary servers are part of an existing System Platform 6.0 High Availability configuration, the upgrade process requires you to Stop HA and Remove HA on the primary server before completing platform upgrade prerequisites and the platform upgrade procedure on either server. System Platform does not support platform upgrades while High Availability is running. If you attempt an upgrade with High Availability running, a warning message appears and the system prevents you from performing the upgrade on either server.
When the Services VM Network Configuration window appears at the beginning of the System Platform upgrade for the standby server, deselect the Enable Services VM checkbox to ensure that you install the Services VM in a disabled state. If a failover occurs later during HA system operation, the failover subsystem activates the Services VM on the former standby (now active) server, propagates the current Services VM configuration to that server, and deactivates the Services VM on the former active (now standby) server.
After completing the platform upgrade on both servers, you will need to reenter your SP6.0 HA configuration and then Start HA on the primary server.
