We have allocated 8 ports (4 in each fabric) from Brocade 5300 to HP Blade Center BL460C-G8. Issue is that from HP Blade Center SAN pass-thru switch ports on the blade enclosure show connected but at switch end all ports are showing as no-sync. Intially Port Speed was set as AN and also we tried setting all mode of speed(2G,4G,8G) but nothing works. We have done fiber cable cleaning for all the ports as well. We have deliberately changed port type to F-type. Nothing works. Suggest me is there any thing needs to be checked at HP Blade center end and as well as at Switch end.
