DMP support for handling FPIN events

December 9, 2025

Contributed by:

DMP now supports Fabric Performance Impact Notification (FPIN) events. FPIN provides notifications in case of any failures or congestion issues related to storage paths. DMP monitors these events and automatically determines an alternative path to use to prevent degradation in the IO performance. A new tunable parameter, dmp_monitor_fpin_event, is introduced for enabling and disabling the DMP FPIN monitoring functionality.

Refer to the Event monitoring chapter in the Dynamic Multi-Pathing Administrator’s Guide for more information.
