The 5 comes from SD_MAX_RETRIES used by the sd driver if the IO passes through sd_prep_fn which most normal block IO would. One could see lower retry values if the IO is coming through other drivers (i.e. the sg driver). This value is not configurable. -andmike -- Michael Anderson [email protected] -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
