Has anyone been using RECONSTRUCT=YES with MOVE NODEDATA?

What's the impact compared to RECONSTRUCT=NO?



The default is no, which seems strange. I would think you would want to reclaim the empty space when you consolidating.



We are trying to consolidate years worth of incremental backups (200+ volumes per filespace) to a more manageable number of tapes. We aren't able to take full backups with most of our nodes.

I always set RECONSTRUCT=YES when I do a move data on a volume. TSM will sometimes mount a different volume first and read a little data off before mounting the source volume. It does not seem slow with it set to YES, but I have not put a timer on it.



Hope this helps,

Andy
