Hello Jason,

I use the rmt devices provided by the IBM tape driver.  If you're using non-IBM drives, I think you still have to use the TSM device driver.

Regards,

Hi,
       I am installing new systems and traditionally would have converted my rmt devices to mt TSM devices.  Is this now a legacy activity to perform?

We are using LTO Ultrium 6 drives and whilst interrogating the rmt device I can see a lot more tuneable attributes than when converted to mt device and using the TSM devices.
