High Availability - "disabled" Failover Type - not what you expect

[Craig Wyllie]

Please note that the "disabled" Failover Type in the High Availability Server module is actually only intended to be used for "scheduled maintenance" of a server layer, during which time the agents whose "primary" is that server layer, should not switch away. They are allowed to switch back to this server layer, if it's available.

To put it another way:

From the perspective of an agent with the HAClient module on it, it doesn't care about the failover type of it's backup server layer, even if that's the server layer it's "current server" is the backup server layer. And in fact if the failover type on it's primary server layer is "disabled", it will still switch back to that primary server layer if it's up and running!

To ensure that agents do not fail back to their primary server layer until you want them to, simply ensure that the primary server layer's HAServer module remains in the "Forced" failover mode, or remains off, or does not have the HAServer module loaded.
