Hi

 

In a previous post I ask for advice on retiring an old library and
commissioning a new library in its place. I have reached a point where I
am not too sure on the direction to follow.

 

I have migrated all my storage pools (sequential) to the new library,
and they are working fine. I created a new devclass pointing to the new
library.

 

I have created a new Offsite Copy Pool for my DR offsite tapes, and this
is in use. My old Offsite Copy Pool is no longer being used on the old
library

 

3310 is the new library

3583 is the old library

 

LTO3DEVCL is the old devclass pointing to the 3583

LTO3310DEVCL is the new devclass pointing to the 3310

Further Questions.

 

1. Is it possible to move the old offsite pool (OFFSITE) to the new one.
I was told to just leave it and it will diminish to nothing over time
with reclamation which I agree and understand. Not sure why, but it
would look better and have all media in one logical group.

2. My TAPEPOOL is 19 tapes, and migration will take forever to the new
TAPEPOOL_3310. 

   Is there a way to check the tapes out and then check in to the new
library or is 

   migration the only way to go.

3. Should I change my old devclass to point to the new library i.e
LTO3DEVCL to point 

   to 3310LIB instead of 3583LIB

 

 

Thanks in advance
