Hi all,

I have 2 questions on this: If you only got the virtual volumes because
the primary place ( library+tsm-server)  ist completely destroyed ... but you 
got the
tsm-db recreated on some box ->  you will have access to the data through the 
virtual volumes.
question1: can the recreation of the primary data only be done using the same 
Hardware
- same library , same drives  ?
If the answer is yes : is there a technical reason ?
if no: why should the primary pool not be recreated on an alternative
remote-tsm-server, just using virtual volumes of that server ?
I thought virtual volumes on remote server could be used for primary-pools ?

Greetings
Rainer
