The configuration from the description is not valid. We should not be able to use bs-type rdwr and device-type pt. See BZ#1008528. On RHEL-6.7 an error is returned when using this invalid config. scsi-target-utils-1.0.24-16.el6.x86_64 # service tgtd start Starting SCSI target daemon: [ OK ] tgtadm: invalid request Command: tgtadm -C 0 --lld iscsi --op new --mode logicalunit --tid 1 --lun 1 -b /dev/sdb --device-type pt --bstype rdwr exited with code: 22.
