The volume was detached without export it first. 
Trying to attach Volume back but it creates an error that the volume name already exists. 
We need help to bypass the error and reattach the volume back to Admin Console so we can export it properly.

Then we restored the data from a backup and when we try to attach the Volume we get the error. 
" There is no exported volume at that location"

The question is:

Where does Laserfiche stores the information as to whether a volume is attached or not? 
?SQL 
Do you think if we rollback SQL prior to the fail detachment Laserfiche will think it is attached again? 
Alternatively is there a way to attach the volume to when Laserfiche doesn't recognize it as a valid volume?
