Hi Debbie,

    There is absolutely no reason why you can't separate your current
configuration into a Library manager and library client without losing data.
IMHO the vendor that you hired does not seem really understand how TSM
works.  I recently had to do something similar here at UC Berkeley with our
3494 Library; and while it can be complex and time consuming, it can be done
without any data loss.

Subject: [ADSM-L] Library Manager and Migration question

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.
