Gentille, No big deal, on 4.1 or later; you set up one TSM server as the library manager, so all tape mounts go thru that server. Then, the shared drives are connected to both servers, so when a drive is allocated to a given server, the other one won't access... see the Admin. Guide (and 3584 doc.s) for more details.

Each TSM server will see its partition as standalone library with number of drives and slots as assigned to that partition. Detailed description is available in 3584 Planning and Operator Guide, Chapter 4 "Advanced Operating Procedures, Configuring the Library with Partitions". The other approach is to use TSM library sharing as Don suggested. This will need some TSM configuration but will allow you to have single scratch pool for both servers instead of separate set of scratches in each logical library (partition). All roads go to Rome (but there are many of them).

Have you or anyone else done this successfully and do you have any information on setting it up? Thanks, Gentille -----Original Message----- From: Mark D.

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. -- Regards, Mark D.
