Hi,
Customer to our SAN infra is requesting to alter the FLOGI quiesce timeout from 2000 to 0 ms (current default value = 0 ms when running > 8.3(1) code) on MDS 9710 SAN switches.
I did mange to find out that FLOGI quiesce timeout did change from default 2000 ms (introduced 8.1(1)) to 0 ms starting 8.3(1). In one environment (4 x 9710 V2) the settings are 0 ms (the default) and in another environment (8 x 9710) it is 2000 ms. I suppose the 2000 ms setting survived the MDS microcode upgrades and it will not change until specifically set by command.
Now IBM is pointing to a document attached
The recommendation is disable FLOGI scale optimization and configure FLOGI quiesce timeout to the default 0 ms.
Reading in the mentioned IBM document concerning flapping port it feels like setting a > zero value for Flogi quiesce is a good thing to do.
So question : Besides default value , any remarks on Flogi quiesce settings, some best practices available ?
