instead of migrate stg diskpool2 low=0 use migrate stg diskpool2 low=50 That will get you a little past 250GB. (50%), assuming the data is spread evenly over a large amount of nodes. Otherwise, you will just have to cancel the process once you free up enough space.
Migrate will move the data based on node name and not by the volume, so you might end up with the same number of volumes used in diskpool2, just with a less percentage utilized. Since you mention now that you want to free up only half of the volumes, "move data" would be the better solution. Identify which volumes you want to remove (choose half the volumes with the lowest pct_utilized, or maybe choose all the volumes disk25.dsm-disk50.dsm) put them in a text file run a loop against that text file with move data commands to move each one to the new pool.

I need to free about 250GB only. What should be the best way to accomplish this using the migrate apporach. Mario ________________________________ From: Howard Coles <[email protected]> To: [email protected] Sent: Wednesday, June 10, 2009 5:34:53 PM Subject: Re: Moving diskpool data Move data may work, but migrate would work better. Is this a File Class pool, or a disk storage pool? Set DISKPOOL1 as the "next storage pool" for DISKPOOL2, and then kick off a migration. You can throttle it by setting the lowmig percentage to something that wouldn't take too long, and then do it little bit at a time. Or just set lowmig=0 and let it run. Examples: Move data diskpool2vol recons=y stgpool=diskpool1 maxproc=1 Or Update stg diskpool2 next=diskpool1 migprocess=2 (or however many you want to run) Migrate stg diskpool2 lowmig=0 (or the number of percentage you want to migrate down to). I'm sure others will have alternate ways, but these should work.
