Retrieval of portions of storage device access data indicating access state changes

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 at least one processing device comprising a processor coupled to a memory, causes the at least one processing device:

• to control delivery of input-output operations from a host device to a storage system over selected ones of a plurality of paths through a network;
• to send one or more requests to the storage system for data corresponding to states of a plurality of storage devices in the storage system;
• wherein the one or more requests comprise a directive that the data corresponding to the states returned by the storage system relate to changes in the states of the plurality of storage devices;
• to receive the data corresponding to the states from the storage system;
• to identify one or more state changes of one or more of the plurality of storage devices based on the received data;
• and
• to manage one or more of the input-output operations responsive to the identified one or more state changes.

A method comprising:

• controlling delivery of input-output operations from a host device to a storage system over selected ones of a plurality of paths through a network;
• sending one or more requests to the storage system for data corresponding to states of a plurality of storage devices in the storage system;
• wherein the one or more requests comprise a directive that the data corresponding to the states returned by the storage system relate to changes in the states of the plurality of storage devices;
• receiving the data corresponding to the states from the storage system;
• identifying one or more state changes of one or more of the plurality of storage devices based on the received data;
• and
• managing one or more of the input-output operations responsive to the identified one or more state changes.
