The ACSLS already exists as the library is shared between the NetBackup 
environment and the MainFrame backup solution. Unfortunately the true 
"partiioning" of the library for SL8500 is not available until next year. Right 
now only the slots can be divide up.

I agree with your ACSLS comment.  I try to NOT use it whenever I can.  If I 
have a choice of two configurations to buy, and one uses it and the other 
doesn't, I'll buy the one that doesn't in a heartbeat.  If you don't need what 
it offers (multi-host sharing of a library using apps that don't share), then 
it only adds complexity.  And if you have that requirement, other library 
manufacturers meet that requirement without adding the level of complexity and 
cost that ACSLS brings to the table.  (They just partition their library and 
make it look like more than one library.)

That having been said, there are a number of STK libraries that require ACSLS 
to control them, such as the 8500.  (Although I hear that they're coming out 
with a non-ACSLS version soon.)

Absolutely.
 
matter of fact, first thing I'd do would be to take ACSLS out of the picture, 
let the master control the robot, configure all of your media servers to use 
the master as the robotic control device and make your whole env. MUCH simpler.

Subject: [Veritas-bu] ACSLS and 2 fiber networks
In an ACSLS environment where you have a single instance of a library
1. The master server is zoned to see all the existing fiber tape drives in the 
library
2. Several media servers are also zoned to see all the existing fiber tape 
drives in the library
3. the master server is configured to be the main scan host.
4. ACSLS server controling the library (duh...of coarse)


Is it possible to create a "NEW" fiber environment to run independantly but 
with the same master as thus:
1. add 2 new tape drives into the currently ACS controlled library 
2. DO NOT zone them to the master (you can't as it is on the old FABRIC)
3. add 4 new media servers on the fiber and zone them to the two new tapes 
drives
4. run SSO in this "NEW" fiber for only the 4 new media servers

I am almost convinced this should work since robotic control is done by ACSLS, 
but..... I am still not certain because the master server can not see the new 
tape drives.
