Try fcping -P for WWPNs, or use -N with the WWNN which should be 0x1000001b214b0a0e. It looks like you have created the VN2VN fc_host on the real device eth6. Normally we would expect the fc_host to be on a VLAN, e.g. eth6.101-fcoe, so that DCB can use proper VIDs when tagging. -- Ross -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
