I am working on Storport miniport and debugging an issue where the Application running Ios intermittently times out, stating that that it did not get any response for the issued IO command.
MPIO with msdsm is configured above Storport. Is there MPIO/DSM statistics to analyze the number of RW commands received by the MPIO layer for the LUN and number of RW commands completed back, to check where the command is lost.
Debug counters suggest that no SRBs are pending with the storport miniport driver.
