Karel, your reference is to 6.1 - note the fix in 6.1.3 - it was supported but 
in many cases you did not get a great dedup percentage. My test was for a 7.1.3 
environment with directory container storage pools. 

Virtual volumes are still very useful for TSM database backups and storing 
Recovery Plan Files at another TSM server. For client data protection, I will 
always prefer node replication.

Regards,
Joerg Pohlmann

Hi,

Storing virtual volumes in a dedup pool is not supported. It was not restricted 
but ....

Kind regards,
