Hello Joerg, One way to fix the issue could be to update the abort option or create a bind/unbind option to unbind/bind the device. Best Regards Guy
PS: What I found for Scientific Linux 7 cd /sys/bus/scsi/drivers/sr echo "4:0:0:0" > unbind echo "4:0:0:0" > bind where 400 is the scsi identifier of the device
