Hello people i have been reviewing the differences between MetroCluster TieBreaker and ontap mediator for a MCC IP deployment. After reading some docs and powerpoint, i am not able to perceive the difference from the applications/services/clients point of view how the two differ among them. ->Mediator can be configured from ontap CLI (or System Mgr) , can also use CHAP and certificates, and also have two mailbox disks to store MetroCluster info, monitored from ontap systems itself. ->TieBreaker can autosupport , polls the nodes, log collection and snmp traps, and can initiate a switchover Reading this from manual-documentation, https://docs.netapp.com/us-en/ontap-metrocluster/install-ip/concept_considerations_mediator.html#how-the-ontap-mediator-supports-automatic-unplanned-switchover "When a node detects a site failure requiring a switchover, it takes steps to confirm that the switchover is appropriate and, if so, performs the switchover. Mediator Assisted Unplanned SwithOver is only initiated if both SyncMirror mirroring and DR mirroring of each node’s nonvolatile cache is operating and the caches and mirrors are synchronized at the time of the failure" i have some doubts about using the classical Tiebreaker VS Mediator on behalf of failure scenarios. Could anybody shed some light and explain explicit failure scenarios and how differ Tiebreaker and Mediator when is required? Thanks in advance
