I am in the middle of a large, multi-TSM, shared-library, different OS,
different platform configuration process.  Here is the layout:

Current Configuration
-------------------------------
1-3494 ATL which consists of 8-3590B, ESCON attached drives (uses
exclusively by our z/OS system) and 4-3590E1A FC attached drives via SAN
1-TSM z/OS server                                       (A)
1-TSM AIX server using the E1A drives in the ATL        (B)

Future Configuration (adding to existing configuration - nothing will be
removed)
------------------------------
1-3583-L72 Library with 2-3580 LTO2 drives accessed via SAN
1-TSM AIX server                                        (C)
1-TSM WINDOWS 2003 server                               (D)

For a total of 4-TSM servers accessing/sharing 2-Tape Libraries with each
TSM server needing to access both libraries, simultaneously !

The additional servers is mostly due to HIPPA/Firewall requirements (don't
go there............)

Here is what I need to setup/configure.

Both the new AIX (C) and 2K3 (D) TSM servers will need to access/share the
E1A drives and the LTO2 drives. Whether the existing TSM AIX (B) server
needs to access the LTO2, has not been discussed but probably likely.

I have been digging through the books and understand that ALL (with the
exception of the TSM zOS server) need to be crossed-defined to each other,
so that they can communicate with each other as to who has what drive,
etc.  However, never having done such a configuration, I am somewhat
unsure of all the pieces-parts and configuration needed to set eveything
up properly.

I know about the different library PRIVATE/SCRATCH category codes for the
3494 ATL and defining the libraries as SHARED.  I also understand about
having to checkin/checkout the tapes that each TSM server will be using.
Also, I have configured all of the LAN definitions to the 3494 ATL, for
all of the sharing/managing systems.

Never having done a WINDOWS based TSM, so I am a little confused on the
hardware definition aspect. For instance, while I was able to install the
drivers for the tape drives the box sees, via SAN/FC, I can't seem to find
a definition for the 3494 ATL library itself while the 3583 LTO library is
coming up as an "unknown library". The TSM devices are there (i.e. the
3585 is lb0.1.0.2) but what do I use when defining the path ?  When I
tried using the lb0.... it did not like it ?

Any help/suggestions/recommendations/thoughts on this configuration
"challenge" will be greatly appreciated !!!

Sorry about being so long-winded.......
