ULTRIUM-TD2 Tape drive using stape driver.

[KiddA]

Hi people ... I need to know how do i do to change my tape drives to start using atdd driver instead of stape.

Atdd is installed and loads at boot.
Should I disable stape?

Hi

Does the driver works properly with stape driver?

You could remove the stape driver.so that atdd driver will bind with that drives.

In 11iv3, we have a command called "iobind" to bind a driver to a particular device.

The tapes are working with stape driver. But data compression is not working properly.

How do I remove stape driver? You mean disable it from kernel? Do I need to reboot so tape drives start using atdd?

Thanks for your time,
Regards.

Hi,

You may have already figured this out but you can use "/opt/atdd/bin/atdd_claim" which will go out and claim any tape drives that are turned on to use the atdd driver instead of stape.

I hope this helps
