Issue

During a site failure in a four-node MetroCluster IP configuration, a failure involving a partner mediator mailbox disk may briefly disrupt access to all mediator mailbox disks on a surviving node. The node may then disable automatic unplanned switchover (AUSO). If AUSO is disabled on a required node, the automatic switchover may not proceed, and a manual switchover may be required.
