Problem Symptom
=================

Malfunction of "saveconfig" or "exit" from targetcli, after configuring a
"backstores/pscsi/dev_sda" via the command:

421-lio:/etc/target # targetcli /backstores/pscsi create dev_sda /dev/sda

Where /dev/sda is an iscsi/iblock device, and been used to simulate a SCSI
disk. Indeed, pscsi functionality works well so far.

Expected Behavior
=================

I assume this is a valid configuration, and the error should be removed. Might
be worth to book a real SCSI disk server to validate the behavior.
