Note:

* Simultaneous failures of components

** Pre-Election completes before second component failure.

*** Assumes the ‘Other Array’ was not the Pre-Elected array. If the Pre-Elected array fails then the stretched pod volumes are unavailable.

Note: If the Mediator becomes unavailable after an array failure or a replication link failure has already been sustained, access to the mediator is no longer required and access to storage remains available on one array.
