It is fixed but the reason there have been suggestions to use a file type 
device class is because disk pools unline sequential pools are scanned from 
begining to end for every storage pool backup. I have had some customers that 
have millions of directories in their DIRMC pool.  Even when none change they 
backup runs from hours on that pool.  With a file type device class only the 
new volumes would be backed up resulting in a much faster backup.  Now all that 
being said this new feature in V5.3 warrents new consideration.  My new 
consideration is to stop using DIRMC pools as the reason they were created in 
the first place has also long been fixed.

OK, after spending a large portion of my day reviewing adsm-l post going back to
2000, I'm still not sure. Does anyone know if there is still a performance 
problem
running reclamation on a DIRMC random access disk pool?
I came across one post that said it was supposedly fixed, but recommended using
a file type diskpool to be safe.
