My understanding is, you are supposed to use the IBM atdd drivers with IBM
LTO drives. But you must use the TSM supplied tsmtape drivers with brand-X
LTO drives. This may apply to other tape technologies as well, DLT for
example. I have IBM LTO2 and LTO3 drives, and use the atdd drivers. At
our DR site (HP), they have HP drives and I must use the tsmtape drivers
there. Same is true for libraries: IBM libraries use the acdd driver, but
brand-X (like my STK L700) use the tsmtape driver.

Greetings,
Quick compatibility question I haven't seen discussed. If it
has
and I missed it, I am sorry.
My preference with IBM tape libraries and LTO drives on a TSM
server
is to use the IBMtape drivers, not the TSM drivers. In fact, I wonder why
Tivoli even has a special driver for IBM's tape drives, when IBM provides a
perfectly good one. I am about to upgrade a TSM server I just inherited
from TSM 5.2.x to TSM 5.3.4 on a new box, and wanted to standardize on the
IBMtape drivers from here on out. But I am also migrating a 3583 tape
library with LTO1 drives and tapes that are already written with the TSM
driver, and I am wondering if I am going to have a problem afterward being
able to read the tapes written by the TSM driver.
Can anyone tell me for certain if this is going to be a
problem, or
do I have to stay with the TSM driver? I don't really have anything
against
the TSM driver, I just want to make all my TSM servers the same
configuation
as much as I can.
Best Regards,
