We tried file device class with our onsite pool with disappointing results.
I believe the problem was our decision not to stripe across LUN's.  This
would have made performance much better, at the cost of a LUN failure
causing more damage than if we used them indicidually.  Now, I can't
remember the last time I saw a LUN failure, but YMMV.  We will probably
address this issue again when the decision is made to move our copy pool to
disk.

We are migrateing our copypool from cartridge to a DS4800.

From the manuals copypools only support FILE type devices.

My assumptions ( on AIX) are:

-I create logical volumes and file systems
-Define the device class
-TSM then creates the files in the filesystem

Anyone ever done this with copypools on AIX?

Know of anyone using a vaulting service with transmissions over the
Internet with TSM? We're at capacity and looking for options.
