Mark Stapleton responded:
Yes. The TSM server that is attached to the library can be a managing
server, while the remote TSM server can be managed. It's not exactly true
library sharing; it's more like the managing server honoring a request from
the managed server to run data to tape.
I have tested a similar configuration, but using an ADIC Scalar 10k instead
of a 3584. I found that using 3 TSM servers works better than 2. Make the
library manager just manage the drives, and do nothing else. The reason I
did this was the way mount limits work on the managing server. A drive
allocated by the library manager to a library client can (at times anyway),
show up as allocated on both the library manager and the library client
servers - it's not actually in use on both servers at once, but it counts
against the mount limits on both servers. I found it simpler to just set
up a separate server as the library manager.
