Path failure information sharing between host devices connected to a storage system

A method comprising:

• obtaining, by a first host device comprising a processor coupled to a memory, an input-output operation that targets a logical volume of a storage system comprising a plurality of storage devices, the first host device being configured to communicate over a network with the storage system, the first host device being configured to deliver input-output operations from the first host device to the storage system over the network over selected ones of a plurality of paths;
• transmitting the obtained input-output operation to the storage system over a given path of the plurality of paths;
• determining that the given path has failed to convey the transmitted input-output operation to the storage system;
• and
• causing information comprising an indication that the given path has failed to convey the transmitted input-output operation to the storage system to be provided to a second host device that is configured to communicate over the network with the storage system using at least a portion of the given path that has failed.

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code, when executed by a first host device that is configured to communicate over a network with a storage system comprising a plurality of storage devices, the first host device being configured to deliver input-output operations from the first host device to the storage system over the network over selected ones of a plurality of paths, causes the first host device:

• to obtain an input-output operation that targets a logical volume of the storage system;
• to transmit the obtained input-output operation to the storage system over a given path of the plurality of paths;
• to determine that the given path has failed to convey the transmitted input-output operation to the storage system;
• and
• to cause information comprising an indication that the given path has failed to convey the transmitted input-output operation to the storage system to be provided to a second host device that is configured to communicate over the network with the storage system using at least a portion of the given path that has failed.
