I'm looking at updating one of my tapedev devclasses to only use 2 drives instead of all and I'm not sure if it's possible.

I have 2 LTO4 drive and 4 LTO5 drives but I have a couple of processes I would just like to use the LTO4 drives so that they won't affect any other running processes for the LTO5 drives.

Since LTO5's can write and read to LTO4 tapes I've had it just use an LTO5 drive for these lto4 related processes but I'd prefer to set the mount limit specifically to my 2 drives that are LTO4.

Is this possible or since all drives in my library can write to 4's I have to let it use any free drive?

You would have to update the LTO5 devclass to only be able to use ULTRIUM5,ULTRIUM5C and similar for the LTO4: ULTRIUM4,ULTRIUM4C.

If you keep format=drive, then it will mount anything the drive can use.
