Answer
- The back-end network (iSCSI/iWARP) traffic must not share failure-domains with traffic for Mediator communication
- When shared switches in the core network (for both MetroCluster IP back-end & Mediator connectivity) are rebooted, connectivity to both the Mediator Service
and the remote mailbox disks are disrupted - The nodes at the disaster site will self-halt & the nodes at the 'surviving' site will trigger a switchover if the above conditions are met
