Thanks a lot for your reply, I had stopped NPIV setting for this purpose.
And I still have another questions for SR-IOV, is it supported by esx + fibre? I searched the document, all the examples are ethernet implement.
Since my host with Emulex HBAs, I found that Emulex have management softerware:OneCommand Manager, do someone know if it support VMWARE? I installed the vSphere client plug-in, and this plug-in only support listhba, no createvport found, I am not sure if I need addtional software or other setting to enable it.
Thanks a lot!
