Abstract
Using host connectivity states to avoid queuing I/O requests: identifying a fault in data communications between a first storage system and a second storage system among a plurality of storage systems across which a dataset is synchronously replicated; updating, upon identifying the fault, an access state of a data communications path between first storage system and a host from an active state to a transitional state with respect to the dataset; and indicating, to the host, a first access state change.
