Hi FCoE community,
I have a problem that has hopefully already been solved by someone out there.
I have a Brocade 1020 dual port CNA (Firmware v126.96.36.199) cabled to a Cisco Nexus 5020 (Firmware v.4.1.3.N1.1.)
At boot time I cannot manage to get the ports on the CNA to bring up the Nexus ports, so there is no access to its boot LUN.
However when I boot using the Brocade live_cd_v2-1-0-2.iso I am not only able to bring the Nexus ports live but also access the attached storage.
To bring the ports live I must shut/ no shut on the Nexus, which is not really adequate and I'm looking for a solution to this also.
Any help appreciated.

The LiveCD provide only for alternate method of Update the Firmware/BootCode and not from Booting from a SAN.
I'm not 100% sure, but i think your must upgrade the Firmware with Boot Option.
Please check for another BootCode / FW Release.

Sad news. The 1020's, or at least the 1020's distributed by IBM for their System X servers as part number 2C1820 suffer a known problem when using the Brocade Copper cables with the Nexus 5010 and 5020 models.
"When using the Brocade 10 Gb CNA for IBM System x, Option 42C1820, Field Replaceable Unit (replacement part number) 42C1822, using the Brocade active SFP+ copper cable:
If the cable is disconnected and reconnected to a Cisco Nexus 5000 series (Cisco Nexus 5010 or 5020), the link does not come back up on its own."
Use the Brocade 10 Gb SFP+ SR Optical Transceiver, part number 49Y4216 replacement part number 42C1819."
IBM has not certified the Brocade CNA on the Cisco Nexus 5000 series. Brocade has done some level of certification. The Brocade SFP+ active copper cable has this issue. The optical solution with optical SFP+ does not have this issue."
Apparently competition in the market place is a good thing some old fool told me once...
