Anil,

I fully agree with you that a TSM server acting as a library manager
would have been much easier to implement and maintain, unfortunately
legal and security issues are refraining us to do so ! (plus the fact
that we also plan to dedicate a future partition of the library to some
non-TSM application)

Thanks anyway for your help ...

Cheers

Arnaud

I would recommend use only one library manager. This simplifies lots of
headache in future. I am having one 3584 tape library with 18 LTO2 and 6
LTO4 under same library manager and it works like charm.
One library manager means one volume history which is lot easier to
maintain.
Good luck

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

Hi All,

A probably trivial question, but I'm unable to find necessary
information in the books ...

Our TSM setup is actually made of a TS3500 library equipped with 15 LT03
drives and an expansion frame, the whole being shared between 2 TSM
servers, thru the mean of "standard" library sharing (contiguous drive
and slots for each logical library).

So far, our logical libraries are looking  like:

- 1st partition : 7 tape drives (frame 1 row 1-7)  and  slots 1025 -1375
- 2nd partition : 8 tape drives (frame 1 rows 8-12, frame 2 rows 1-3)
and slots 1376-1707

Note that the 3 last drives (frame 2 rows 1-3) where recently added, and
are so far not used by any TSM server ...

What we intend to do is to activate ALMS to create a 3rd partition which
should be made of 3 drives (the 3 ones which are still not attributed) +
approx. 50 tape slots, and to use that one for a new TSM server.

My questions are  : 

- what are the possible issues (if any) that I could face after having
activated ALMS and created the 3rd partition ? 
- Is there any chance that our productive TSM servers could loose track
of the already in use volumes, or of their drives ? 
- Will my actual partitioning still exist after ALMS activation ...

Well, in some words : what shall I care about, before activating ALMS on
an already partitioned and productive library ?

Hopefully someone already went thru this and will give me some hints !

Thanks in advance ...

Cheers.

Arnaud
