Fixed In Version: kernel-2.6.32-71.4.1.el6
Doc Type: Bug Fix
Doc Text:
Previously, timing issues could cause the FIP (FCoE Initialization Protocol) FLOGIs to timeout even if there were no problems. This caused the kernel to go into a non-FIP mode even though it should have been in the FIP mode. With this update, the timing issues no longer occur and the kernel no longer switches to the non-FIP mode when logging to the Fibre Channel Switch/Forwarder.

in kernel-2.6.32-71.4.1.el6
Comment 5 Gris Ge 2010-10-15 03:18:28 EDT
Cannot reproduce this issue with "Emulex LPe12002-M8".
It's firmware version is :
1.11A5 (U3D1.11A5), sli-3

Kernel version: 2.6.32-71.el6.x86_64
Reboot 5 times, no lpfc kernel panic came out.

As comment #1 spot out:
>Emulex believes there is exposure to this issue in large SAN environment where
>the device discovery process could see delayed responses which result in iocbs
>being queued.

Do we need a large SAN environment to reproduce this issue?
