Also consider setting different label prefixes (this is done by devclass) for each
server

It also might help if you use different Volsers for each TSM server.
I have an ATL with 12 drives, 4 per server with Volsers Axxxxx for Server1
Bxxxxxx for Sever2 and Cxxxxxx for Server3 ..

Please respond to

We ran option 1 for a long time both with twintailed scsi and a san but
have
now mostly switched to option 2. We shared all of the drives and
frequently
ran into problems where tsmsvr1 had a drive and tsmsvr2 tried for awhile to
use it and then marked it unavailable until I marked it online. With 1 you
definitely need different catagories and you have to be careful. It makes
it easier if you use 100's for one and 200's for the other because I want
to
say the number above the scratch is automatically saved for the same
systems
private or vice versa and it can get you in trouble. The best explaination
I have run into on how to set up the library manager is in the LTO Open
Redbook and you just modify what you need for 3494.
Good luck
Becky

Two ways to set this up:
1. Two separate TSM server sharing the library: use different categories
and
be careful.
2. Have one of the servers act as the library manager. The second asks the
first for resources and tape mounts, etc. The first server knows about all
of scratch volumes, same categories. See library sharing documentation.
You also need a license for this option.
Option 1 with the 3494 is probably the way to go. Unless you have SAN
attached drives. Then use 2 so you can share the drives between the two
servers.
IMHO.

I am in the process of setting up a second TSM server on the same
machine. I was curious if there are others doing that with a 3494
ATL. From what I can tell you can share the 3494 atl resources between
the two servers, meaning the tapes and the drives by specifying a
primarylibrarymanager. Do you use the same scratch and private categories
for the tapes used by both servers?
