Re: [ADSM-L] ALMS activation on productive shared TS3500 library

Hello,
if you activate ALMS, then the already defined logical libraries will be 
preserved with all information and setups, like size, drives, cartridges 
...
How ever you should stop the activities on our TSM Server regarding 
libraries.
After activation, which may take 1-3 min per Frame, you should:
-check the logical libraries with the WebGUI
-check if the cartridges "assigned" to the logical libries, this may take 
a while (after the automatic inventory)
-if where the cartridges not assigned, then you need to assign the cart 
manually with the WegGUI (this should be normaly not necessary,  but it 
happens once to me) 
- run an audit lib

Thats all.

After that you can change the library setup with ALMS capabilities.

I have a ppt which explains ALMS and TS3500 WebGUI, but it is about 8 MB, 
if someone interested pls pop me email ....

Re: [ADSM-L] ALMS activation on productive shared  TS3500 library



 Hi,

Do you speak french ?

May I make some suggestion...

I work with a huge library, TS3500, with 7 virtual libraries (ALMS) 
defined...

1. Do you really need to partition the library ?
                 A library manager is a good and scalable solution...

2. Traditionnal partitioning (ie physical partitioning) and ALMS (virtual 
libraries) are exclusive solution.
                 You can't mixt the two solutions.
                 I mean, if you activate ALMS, you should loose all 
physical partitioning

Activating ALMS mean a complete change of strategy regarding how you use 
your 3584

To activate ALMS, which is a very nice "virtual libraries" solution... :-)

A) note all tape label for each actual partition
B) activate ALMS
B.1) create two virtual library, corresponding to the old partitions
                 allocate drives to each library
                 connect and define all tape on server side
B.2) allocate each tape to each corresponding virtual library
B.3) launch audit libr on each tsm server
C) create the third virtual library
D) Enjoy it
