BIG FAT WARNING!
Open-iSCSI Regression Test Suite is about to start. It is going
to use "$device" for its testing. iSCSI session could be re-opened
during the tests several times and as the result device name could
not match provided device name if some other SCSI activity happened
during the test.
Are you sure you want to continue? [y/n]:
