We have several Brocade 4/24 SAN switches for HP c-Class BladeSystem in blade systems. These switches are configured in Access Gateway Mode (NPIV) and connected to a McData ED-140M. In the EMC Connectrix Manager console, these Brocade blade switches appear as isolated devices, not as member switches of any fabric. But suddenly one Brocade switch “became” a real SAN switch and Connectrix issued a Fabric Event message saying an ISL link was added between the Brocade blade switch and the McData ED-140M. Few minutes later, the ISL was removed as the Brocade blade switch disappeared. There were Fabric Event messages about the ISL removing. The whole process repeated soon after and lasted for last two days now. Is this a known issue? Will a reboot of the Brocade blade switch fix it?
McData ED-140M has EOS 09.07.02 1 and running in Open Fabric mode. The Brocade blade switch has FOS V6.1.0c.

I don't think a reboot fix the problem. Probable is here a defective SFP, which caused a lost of connection.
