If your first statement is No BACKUP has been taken, then the file is most 
likely lost.

When was the file migrated?

Can you show us the results from a HLIST dsn(/) BOTH 

It will help to know when it was migrated.

CDS Backups and Journals can be performed anytime.  You just have to know what 
kind of performance impact will be felt while it is running
