Re: [ADSM-L] Convert to TSM Devices or use the rmt device

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.
