Wayne, Starting at server 4.2 (or maybe 4.1.something), there is a RECONSTRUCT parm you can add to MOVE DATA to get the aggregates rebuilt along the way! (RECONSTRUCT=NO is still the default).
I haven't done any timings on it, though, to see if it's slower. Wanda -----Original Message----- From: Wayne T.

Long on tape drives? Create another domain (& storage pool(s)) and split your nodes between them. - MOVE DATA (tape to tape, or tape back to disk) allows multiple simultaneous processes on one storage pool and each is often faster than the corresponding reclamation. The down-side to MOVE DATA is that aggregates are not reconstructed, so your newly filled tape will immediately have reclaimable space. Perhaps a statistician could tell us the expected wasted space remaining after a MOVE DATA. Maybe with too many caveats to be useful, ... but when I switched from exclusively performing MOVE DATAs to exclusively performing reclamation, I "gained" almost 20% empty volumes. cheers, wayne Wayne T.
