We purchased some new media to expand out library. Same manufacturer just larger tape media. Going from 1.5TB to 2.5TB. I went to label the media and got this error. The medium is not compatible with the device or media pool.
If you have a LTO5 tape drive, you would not be able to read a LTO6 tape. Hence the incompatibility.
You would need a LTO6 tape drive to read LTO6 tapes.
