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.
