We origionally had 2 (at different datacenters) big TSM instances (+150gb
db each), each with their own library.  In preparation for adding new
instances we converted to standalone library manager instances (one at each
site), then brought on new instances.  It all worked very well.  There are
a couple docs about how to convert a standalone tsm instance to a library
.manager  and library client setup.  I can think of no reason you could not
do this.

We origionally had the library manager instances on the same server as the
main TSM instances.  We have since moved the library managers instance to
tiny standalone AIX lpars.  This allows us to upgrade them first without
having to upgrade the main tsm instances at the same time.

Hi All,

We currently have 1 TSM server ver 5.3.3 on AIX 5.3, with a large database,
228GB.  We have finally received approval to move this to a new server,
upgrade to 5.5 and split the clients up to reduce the DB size.  We would
like to have 4 LPAR's created on the new server, 1 for a Library manager
and the other 3 for client databases. Our library is a TS3584 with 12 LTO2
drives.  We are adding another expansion cabinet and adding 4 LTO3 drives
but are staying with LTO2 tapes for now.  Our current library configuration
has the library shared but it is not a library manager since we only had
one server.

Due to the size and complexity of our environment, we contracted with a
vendor to do the setup and start the process.  Now that the contract has
been signed and we have started our planning sessions, the vendor is having
a problem with the library manager/client configuration.  At first he said
that there was no such thing.  I sent him documentation and they also found
an IBM redbook on the subject but now says that it is too complicated since
our server is so large and that I will need to partition the library, with
some data loss!!  I am strongly against this setup and would like to know
if I am wrong.  How difficult would it be to create a library manager and
client setup for an existing environment?  I currently have over 1000 tapes
onsite and as many offsite and naturally do not want to lose any data.
Thanks for the feedback.
