This error indicates that the Fibre Channel peer exists and can communicate with iPXE, but the peer does not support operation as a target device. Things you can try: * Check that you are using the correct Fibre Channel WWPN in your root-path. * If you are trying to boot from a software target, check that the target functionality is enabled. For example, if you are using [[http://scst.sourceforge.net/|SCST/FCST]] then check that the file ''/sys/kernel/scst_tgt/targets/fcst//enabled'' shows the value ''1''.
