There is never a case where the trailing bytes for $NPIV_WWPN + $NPIV_WWNN would be different, right..? If that's the case, then collapsing the /sys/kernel/config/target/qla2xxx/ formatting to $PHYSICAL_WWPN:$NPIV_WWPN makes sense here, and simply generate the $NPIV_WWNN required for fc_vport_create() internally in tcm_qla2xxx code. > > * Determine proper NPIV format for EVPD=0x83 SCSI name string > > AFAICT this should be the $NPIV_WWN + port_id, correct..? > > Aside from these remaining issues, multiple NPIV ports can be configured > > on a single physical FC port, and initial I/O appears to be functioning > > as expected. > > > > That's good. > > :-) --nab -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
