Be very careful with enabling FDMI on QLogic cards. We experienced a fairly nasty problem shortly after having enabled FDMI on one server in a fabric. As a matter of course I backed the FDMI enable out along with some other changes, although initially believing that it was unconnnected. However in a conversation with a third party a few days later, they described a problem that had been linked to QLogic FDMI that exactly matched our symptoms. We have not re-enabled FDMI on QLogic cards since then.Of course your mileage may vary ...

Sorry, I don't have note of the firmware levels at the time. But symptom was multiple QLogic HBAs in fabric disabled (Emulex in fabric unaffected). Reboot of associated servers was required to re-enable HBAs, unable to identify any other method (we tried...).
