.SH "DESCRIPTION"
.PP
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 nor allow dev_loss_tmo to exceed that limit if failing I/O fast has been disabled\&. Furthermore, these parameters must be such that multipath can detect failed paths timely\&. Hence do not allow all three parameters to be disabled simultaneously\&.
