Abstract:
An apparatus comprises a host device that includes a multi-path input-output (MPIO) driver configured to control delivery of input-output (IO) operations from the host device to first and second storage systems over selected paths through a network. The MPIO driver is further configured to identify a connectivity failure between the host device and a given one of the first and second storage systems, to generate a message comprising one or more details of the connectivity failure, and to send the message to a remaining one of the first and second storage systems over at least one path of a plurality of paths between the host device and the remaining one of the storage systems. The first and second storage systems in some embodiments are arranged in an active-active configuration relative to one another, with one being designated as a non-bias and the other as a bias storage system.
