Re: License for Managed Library?

1. Library Sharing is pretty descriptive - it is required if *the TSM 
server* will share the library. As already answered if 3494 is partitioned 
and different servers use different cartridge categories it is not 
required. If TSM server will share the library, either with another server 
or with storage agents, it *is* required. Because you have defined storage 
agents (they actually get defined as "servers") you see "Is Library 
Sharing in use: Yes".
2. Managed Library is depending on the size of the library for both # of 
drives and # of storage slots. In the past the rule was: it is required if 
library has more than 2 drives or more than *certain* number of slots 
(different for each library but usually 20/30, that's why sometimes "Number of 
Managed Libraries in use" was incorrect). In version 5.1 the 
rule was changed (increased) and for *all* became: it is not required for 
any library with 3 or less drives and 40 or less slots, it is requred for 
more than 3 drives and/or more than 40 slots.
3. Other historic results - "Library Sharing" and "Managed Library" were 
two different licenses for different things. In the past a customer was 
able to have one, the other or both. In version 5.1 they were joined 
within single ITSM Enterprise Edition together with HSM and Storage Agent 
licenses. Later (in August 2002) new ITSM eXtended Edition was "invented", 
HSM became ITSM for Space Management, Storage Agents became ITSM for SANs 
and ITSM XE kept Managed Library and server Library Sharing features. Even 
upgrade from TSM 4.2 having only one of the features to ITSM 5.1 entitles 
for Base Edition and only if you have both upgrade is to eXtended Edition.

Now back to the initial questions:
-       If your 3494 is having 40 or less cells you do not need Managed 
Library feature for v4.2 or Enterprise/eXtended Edition of v5.1. If you 
have more (and I thing you have) you *need* the license even if the server 
does not report correctly the requirement.
-       Shared Library in v4.2 covers number of servers sharing 
library(ies). Both Library Manager and Library Client servers require 
license. For storage agents only the *server* requires the license to 
share the library, the storage agent's license includes license to act as 
library client. So if you had 7 servers you needed 7 licenses. If you have 
one server and 7 storage agents you needed only one library sharing 
license and seven storage agent licenses !!! Demand from the salesperson 
sold the licenses if you are in latter case.

Hi

Depending on the version of TSM you are running, you dont have to buy the 
shared library license:

1. Tivoli Storage Manager required library sharing, and managed library 
license, if the license has more than 3 drives, or more than 30 slots.

2. Tivoli Storage Manager Extended Edition doesnt require either shared 
library or managed library licenses, as they are included within the TSM 
Extended license.

Of couse, the situation differs between running multiple TSM servers 
against a 3494, and running LAN-free agents against the 3494, as the 
LAN-free agents utilize both server-to-server communication, and library 
sharing. In that case, you will require
