Hello Everyone!
How do you know if caching is turned on? How/where can you turn it off? I
am having lousy migration speed perfomance as well. What can I look
at/change? I have an AIX 5.2 server at TSM 5.2.4.0 with LTO2 tape drives
attached. Thanks!

I assume you mean TSM storage pool caching rather than 3390 caching. If
so, I'd turn off caching for a day and see if that makes a difference. It
is my understanding that TSM caching, while optimizing restore times, can
cause performance problems in other TSM areas.
