I'm trying to clarify the behavior of an FCP target when the Fibre Channel
Port Control mode page (19h) is used to set the value of RR_TOV. Please
let me know whether any of the following statements are incorrect.
1. Default values of RR_TOV are 2 sec if RETRY = 0 in PRLI service
parameters and 3 x REC_TOV (6 sec) if RETRY = 1.
2. Changing RR_TOV via mode page 19h overrides the setting of RETRY,
providing a single value for both values of RETRY.
3. If a MODE SENSE for page 19h shows RR_TOV = 2 sec, then it's impossible
for the initiator to tell whether this is the default (with different
values depending upon RETRY) or whether a MODE SELECT has forced RR_TOV to
2 sec for both values of RETRY.
4. If mode page 19h RR_TOV UNITS = 000b, then RR_TOV is vendor unique and
may or may not be the standard defaults.
Thanks,
