Yes it can. And really should be the way to set up recalls because during 
maintenance, your primary LPAR doing the recalls may need to down and if you 
don't have a back up for this function then all your recalls will sit in the 
queue.

Thank You. Looks like CRQ is the right way to go since it insures that once a 
tape has been mounted, it will be used to restore all the files on that tape 
before moving on to another tape. I can see that this has a downside since a 
high priority recall can be postponed since it is coming from a different tape 
(a situation that might not occur with a FIFO if there was the ability to 
insert the request at the top of the queue). You note that CRQ can restrict 
which LPAR does the recall. Can it be set to allow more than one LPAR to run 
the recalls (each with its only tape volume to process).
