Answer


The MCCIP switchover scenario in the middle assumes simultaneous occurrence. When you first disconnect the iSCSI link of the mediator, ONTAP will report the following error messages:

[cf.mccip.med.auso.stDisabled:error]: Automatic switchover disabled: Mediator mailbox disk not healthy.

This means that the Mediator mailbox disk is not healthy, resulting in the AUSO (Automatic Switchover) feature being disabled.
