services.multipath.devices.*.fast_io_fail_tmo
Specify the number of seconds the SCSI layer will wait after a problem has been detected on a FC remote port before failing I/O to devices on that remote port. This should be smaller than dev_loss_tmo. Setting this to "off" will disable the timeout. Quote integers as strings.
