I have an LTO-4 tape connected to a Linux host and Linux creates all the usual devices for this tape as follows:
I normally use /dev/st0 and /dev/nst0 devices for writing to the tape but now I want to try hardware compression. I assumed that I simply need to use one of the other devices but here is the question - which one? I read trough documentation and I even looked at source code of the driver but I could not find a straight answer. So, ideas are welcome.
