Hi Debbie,
Yes, it is true (unfortunately).
The new 3570 library will be a new device; so you will have to define
a new library to ADSM. Then you must also define a new device class
with that new library. Different device classes means different
storagepools. This is a result of the ADSM hierarchy in library,
device-class and storage-pool definitions.
It turns out that a storagepool can never span across multiple
libraries.
I encountered the same problem with four 3995 optical libraries where
this "rule" caused us a lot of headache. In the end we solved this by
reorganizing our filesystem structure and creating an include-exclude
list that made our data go to four separate storage-pools.

We are preparing to add a second 3570 library to our 3466 installation.
Where can I find some good information on how this will work with ADSM,
like how it decides which drives to use, where to go for scratch, etc?
An IBM rep (he may have been sales) said that we would have to use a
separate tape pool in the second library. Is this true? If so, why?
Any replies with ANY information on gotchas, etc. will be appreciated.
