When the High Availability state is locked the system prevents failovers and service redundancy is unavailable. You set High Availability to the locked state only when the 1+1 High Availability cluster is recovering from a network isolation issue. In the locked state, the sessions are not lost from the server processing the sessions during the network isolation recovery.

Under normal conditions the High Availability state must not be locked. After the network isolation issue is resolved and both servers are actively part of the cluster, ensure that the High Availability state is not locked. Both servers must be unlocked to provide failover redundancy.

Use this procedure to lock or unlock the High Availability state of Avaya Aura® MS.
