Hi Wanda,
On my way to work this morning I have been thinking about your situation and I 
think I have an idea how you can get it to work. But only for restore not for 
backup... :)
I haven't try this yet and probably don't have time to test it for you. But I 
think this will work.

Define 4 SCSI Libraries 
Define 4 Drives. 1 to each Library 
Create 3 NEW Copypool Device Class that is pointing to Library 2,3 and 4 
(CopyClass2, CopyClass3, CopyClass4)
And Update one Device Class to point to the 1st Library.
Now do a Audit of the library with Owner=YOUR TSM SERVER

In this stage does TSM know that ALL Tape are available but in different 
libraries.

Technically it should work. The database knows what tape TSM need and only 
change the data entry-path for the tape in the same way it does with the 
"primary" (1st) Library you have. 

This is still just an crazy idea like always that I normally have.


Best Regards

Ämne: Desperation, DR, and four TS3100 libraries...

I'm drawing a blank here, any suggestions welcomed.

I have a TSM customer who makes their copypool tapes using a TS3200 with
LTO4 drives.
The TS3200 is a rack-mounted, 2 drive, 40-mumble slot standard ASCII
library.  No issues.
One copy pool, tapes vaulted and sent offsite.

They want to go to a commercial DR vendor site and do a DR test next week.
The commercial DR vendor, unbelievably, has no multi-drive LTO4-capable
libraries.

Instead, they want us to use 4 (count 'em, four) TS3100 libraries.
The TS3100 is a rack-mounted, 1 drive, 20-mumble slot standard ASCII
library.

There's only 1 copy pool, so all tapes were created on the same device
class.
Ignoring the which-carts-would-go-in-which-library issue, I can't have a
device class pointing to 4 libraries.

And, the TS3100 is built in such a way that unlike a TS3500, you can't open
the doors and access the drives for manual mounting.
(I'd be happy to pull the covers off and try it, ignoring any warranties I
might void, but I doubt the vendor will let me attack the thing with a
screwdriver/wrench/hacksaw.)

If I put all the carts in one TS3100 that will work, but that leaves me only
1 drive to restore all the clients, and they won't likely get done in the
desired time window.

The only thing I can think of to use all 4 drives, is to define those four
TS3100's as 1 manual library with 4 manual drives, and use the front panel
of each TS3100 to move tapes from the I/O slot to the drive when TSM
requests a mount.

(Actually the FIRST thing I thought of, was "cancel the DR contract, this is
nonsense".  But my customer isn't convinced yet...)

Anybody got a better solution?
I've already tried a margarita, it didn't help....
