Yes it's possible, we have one 3494 with 16 x 3592 FC Drives.  We use the LAN 
connectivity option to get to the two AIX TSM servers to see the same tap 
library.  We have the same entries in each of the TSM server's ibmatl.conf file 
which allows both TSM servers to see the library manager.  We also have the 
same library name and definitions set up in TSM on both boxes with different 
scratch categories, (IE tsmserver1 Lib Def = 3494lib1 and tsmserver2 Lib Def = 
3494lib1)  

Our 3592 Tape Drives are SAN attached and we have all 16 Drives zoned to 
tsmserver1 and tsmserver2, but we only define 8 Drives to tsmserver1 and the 
other tsmserver2 within TSM.  We hope to get library sharing setup, but we are 
still migrating 3590 Tape data to the 3592's


Hope this helps.

Subject: Sharing 3494-Library


Hi all,

A question on sharing a 3494-Library :

We have one 3494-Tape Library with 8 SCSI-Attached 3590E-drives. The Library
is connected to an AIX-Server via rs232. The library is only used by TSM.

Now we bought an extension Frame D22 with 4 FC-connected 3592-drives. These
drives should be used by a second AIX-server (running TSM).
My planning is to connect the second AIX-server via RS232 to the library,
and define library and new 3592-drives to TSM. Is this possible and does the
library support two servers connected and do I have to define anything on
the library side? Do I have to use different categories for each server
(even though the used drives and tapes are totally different and not
compatible) ?

Thanks for any help

Chris
