Yep (to the last question);  you cannot span multiple physical libraries to
make a single logical.  You can define multiple logicals within a single
physical;  that is a common thing I've done, for various reasons.

I've got a question.

One 3584-L32 with 6 drives and one 3584-D32 with 6 drives.

Is it possible to have a logical library that covers 4 drives in
the L32, and a second logical library that covers last 2 drives
in the L32 and all 6 drives in the D32?

Or is that not a valid configuration -- ie, do I need to keep
logical libraries from spanning multiple drives in multiple 3584
units?

Hi Dan,

Judging by your configuration I beleive that you have just one physical
library.  I beleive the L32 is the base unit and the D32 is an expansion
cabinet, i.e. the 2 of them are physicaly attached to one another and
share the same robotics.  Is this correct?  If so then yes you can
partition the library as you described.

But the real question is whatare you trying to accomplish?  If this is
to be connected to 2 different servers there are a few more things that
have to be in place.  If both of these logical libraries are to be used
by the same TSM server I am not sure I understand the rational for doing
so.  You could just as easily manage the drive utilization through other
TSM server options.  Please explain a little bit more what you are
trying to accomplish.
