I had many issues in the beginning with FCoE coming online as an access port with Emulex cards. Trunking resolved that issue. As far as recovery goes, I was having problems with the 5010 rebooting on an earlier 5.0(2) code and corrupting portions of my voice lab. That's been resolved with 5.0(3)N1(1b), which has been running a little over a month with no incident. During the reload, the hosts were obviously disconnected from storage, but would reconnect when the fabric came back online. These are the versions I've tested: C210 M[12] - QLogic QLE8152 10 Gbps 2 port CAN 5010 w/ N5K-M1008 8x1/2/4G FC Module Hitachi AMS2100 directly attached to N5k-M1008 CIMC/BIOS version from 1.3 to 1.4(1a) currently ESXi 4.1 Initial release to 5.0 Haven't tested with NPV or NPIV though.
