You cannot "move nodedata" from a primary stgpool to a copy stgpool; you use 
"backup stgpool" for that.  You can only specify a tostgpool on move nodedata 
if from is a primary stgpool.  You can not use move nodedata to move from one 
copy stgpool to another copy stgpool.  And the tapes in question have to be 
either READO or READW; OFFSITE will not work.

That said, what are you really trying to test in your DR test?  If you want to 
know anything about how you might recover in a DISASTER RECOVERY situation, you 
need to take your copy stgpool the way it is.  We don't get forewarning of 
disaster that allow us to make our copy pools better!  If your copy stgpools 
are not in sufficient condition to do a DR, prove it to your management so that 
you can make the argument that they need to allocate enough resource to copy 
stgpool to make it a viable DR restore pool.

Thanks for your help!!

I am preparing for a DR test and I am trying to do some move nodedata
commands on a couple of nodes. When I try to do a move nodedata from a
secondary storage pool (copypool) it complains that the volumes are
offsite. Well of course! I guess I though that TSM would pull the data
from a it original primary storage pool to create the data set. Wrong!


My question is: If I do the move nodedata from a primary storage pool
to a secondary storage pool(copypool), will TSM expire the nodes data on
the 85 secondary storage pool volumes as it aggregates the data onto new
secondary storage pool volumes?

 If it doesn't it will not be of much help since the secondary storage
pool volumes will go offsite for the DR exercise. This seems like the
logical path to me but the doc is not clear on this point and I don't
want to assume here.
