I'm normally using lpfc_nodev_tmo = 1. When I change this to the default value of 35, the system stalls about 36 seconds after disruption. So I guess, the problem is caused by nodev_tmo expiring. I activated the nmi_watchdog, but no output. What can I do to analyze this problem? Regards Bodo BTW: I couldn't reproduce the problem of a wrong WWPN yet.
