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
           Reconnect delay in seconds.

       fast_io_fail_tmo
           Fast I/O fail timeout in seconds.

       dev_loss_tmo
           Device loss timeout in seconds.

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 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.
