SRP_TMO_VALID(9) SCSI mid layer SRP_TMO_VALID(9)
NAME
srp_tmo_valid - check timeout combination validity
SYNOPSIS
int srp_tmo_valid(int reconnect_delay, int fast_io_fail_tmo, int dev_loss_tmo);
ARGUMENTS
reconnect_delay
-- undescribed --
fast_io_fail_tmo
-- undescribed --
dev_loss_tmo
-- undescribed --
DESCRIPTION
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.
