Geoff,
What you will find is that all TDP/R3 data is written to a virtual
file space name by the name of /tdp and tdpmux with a type of API:XINTV3.
So even with collocation file, there is still only one filespace name to
spread things out across.
What you need to do is specify a different management class for each
available tape drive.
That is, if you have 16 tape drives, create 16 different management classes
and 16 different storage pools (each management class copy group point to
its own storage pool), then the SAP admin specifies those 16 different
management classes within thier TDP options file. Backint then round robins
through the different management classes as it sends data to the tsm server,
thus spreading the load out across the different drives.
Actually I create as many management classes and storage pools as I have
drives but I tell the sap admins to use 1 or 2 less than I provide, so as to
leave me with 1 or 2 drives for things like my db backup, etc...
Here is an example of one of my systems...
