Hi Tab,
What are the impact o fusing a FILE rather than a DISK devclass
other than faster reclamation of copypool?
Thanks for the info.

Jack,
It's been mentioned before, but if you use a disk pool for directories,
you should make the disk pool a FILE devclass.
When my directory disk pool was DISK devclass, copypool reclamation would
launch and eight hours later I would have reclaimed a few tens of MBs.
I rebuilt the directory disk pool as FILE devclass, and copy pool
reclamation proceeds at full speed from the start.

I cannot find out how to speed me up either! Mine is slower than sin,
on reclaiming my offsite copypools especially.

Subject: Reclaiminig LTO Tapes
Hey there
Maybe its because I'm used to using STK 9840 tapes but yesterday I saw an
LTO tape at 25 % utilisation take almost 4 hours to reclaim, which to me
is
awful. How am I
supposed to reclaim my tapes with that kind of performance?. The drives I
use are IBM Ultriums in a 3584 library. With only 2 drives it makes it
hard
for users to do
restores...
Are there any options I can change to make this go a bit faster. I know
the
start/stop on LTO's isn't good.
Thanks for the help.
