It only reads/writes single attribute - 0803h "USER MEDIUM TEXT LABEL". It can be used as example how to integrate handling of more attributes; in particular barcode is attribute 0806h. Is it possible to use program such as sg_raw to access that SCSI address directly?
Yes, of course. Anyone know how to do this? Or where to find some useful information.
Well, you can read any available SCSI reference manual for exact format of READ ATTRIBUTE/WRITE ATTRIBUTE commands as well as list of standard attributes (you can find them either on www.t10.org or some links were posted in this thread) as well as check mentioned program how it builds such command descriptor. I would probably try it (out of general curiosity) but I do not have any physical tape library/drive to test.
Therefore being able to read it. But then how to write to it...?
How is writing different? You send the right command to the device ...
Makes sense now you put it like that. I just need to learn the commands first :)
