The combination of the timeout parameters must be such that SCSI commands are finished in a reasonable time. Hence do not allow the fast I/O fail timeout to exceed SCSI_DEVICE_BLOCK_MAX_TIMEOUT. Furthermore, these parameters must be such that multipath can detect failed paths timely. Hence do not allow all three parameters to be disabled simultaneously.
