When failover happens, the mirrored connection that exists on the standby device (the device that was active before failover), might be lost. Connections might be lost because of a traffic group timing issue in the failover process. The connection on the newly-active box remains, however that connection does not migrate back to the original active device if failback occurs.
The connection lost, and is not included when the system fails back to the originally active unit.
This occurs when using mirroring when failover occurs.
no
Mirrored connections are no longer lost on standby systems after failover, and failback occurs correctly.
