LTO4 are 800GB Native capacity. If you are writing compressed data on them, that is all you are going to get.
The "compressed" capacity number that is offered is only marketing. That is just the number you might get if your data compresses at a 2:1 ratio. Some people's data get better or worse than that. It doesn't actually mean anything. >From what I understand, the tape capacity only goes to Full when it physically reaches the end of the tape.

I have LTO4 tapes with LTO3 barcodes on each tape. When the tapes are checked in as scratch TSM sees the size of 1.5gb. When used they go to full status with around 800gb on each tape. Compression is turned on. I believe this is due to the LTO3 barcodes, since LTO3 compressed tapes are 800gb. I need to know if this is the case that TSM is seeing these as LTO3s instead of LTO4s. If someone could point me to some documentation I would appreciate it. I have tried telling this to my management and they do not believe this is so. Thank you.
