Thanks to all who replied (Dennis, Phillip). Official answer from both Emulex and Qlogic is: Only targets (Arrays/VTLs/Filers) follow the "same Node WWN on all public FC ports", initiators (HBA cards) don't follow this convention/rule. So having different Node WWNs on the physically same HBA is "ok". ---------- Forwarded message ---------- From: Sengor <sengork@gmail.com> Date: Mon, Jan 5, 2009 at 6:53 PM Subject: WWNNs and WWPNs To: sunmanagers <sunmanagers@sunmanagers.org> Hi colleagues, Let's assume I've got a single HBA card with 2 fibre ports on it (in this case Emulex card). From what I've understood World Wide Port Names on such a card should be different and World Wide Node Name shold be the same according to the theoretical rules. # luxadm -e dump_map /devices/pci@15d,600000/SUNW,emlxs@1/fp@0,0:devctl Pos Port_ID Hard_Addr Port WWN Node WWN Type ..... 3 1f0027 0 10000000c95d21eb 20000000c95d21eb 0x1f (Unknown Type,Host Bus Adapter) # luxadm -e dump_map /devices/pci@15d,600000/SUNW,emlxs@1,1/fp@0,0:devctl Pos Port_ID Hard_Addr Port WWN Node WWN Type ..... 3 b0055 0 10000000c95d21ec 20000000c95d21ec 0x1f (Unknown Type,Host Bus Adapter) Does anyone know why the WWN Node numbers are different on the physically same card? Is this a Solaris driver issue or the manufacturer has not followed the theoretical standard of WWN Node being the same on each port of the same physical card? -- sengork -- sengork _______________________________________________ sunmanagers mailing list sunmanagers@sunmanagers.org http://www.sunmanagers.org/mailman/listinfo/sunmanagersReceived on Wed Feb 11 19:05:40 2009
