I've done disk moves like this when migrating from older drives to newer drives. Both available at the same time as they were in different expansion units.
With the number of IPL's involved, the length of the IPL's, etc, I do not believe I saved any time off of doing an unload/reload. It even involved an extra IPL which had to be done outside of our quarterly maintenance.
However I have full faith and confidence in our backups and I've done a few full system restores.

Youi might want to pay attention to the first and second sentences of the second paragraph:
"Secondly, this procedure is not supported, and not advised by IBM. You do it on own risk! "
"Bart's" assertion that it is low risk is a bit optimistic. Might it work; Well OK it might, the procedure is straight forward enough, but when you look at what's really being done in that procedure, it's dangerous stuff.
My bigger fear is that it will look and act like it worked, for a couple of hours, then cause problems. By then it's a serious problem to restore back to the orginal point of recovery. IBM support will of course suggest that's your only recourse. Call them when that's done and let them know how it went. (correctly so in my view)

I just read about a procedure to do this last week. I've never tried it personally and as stated in the article not supported by IBM

Subject: Shrink a loadsource
Hi,
Is there any way ( without full system reload ) to reduce the size of a loadsource LUN? Currently having 143Gb LUN's and would like to go for 81Gb LUN's to gain more "arms".
Best regards
Stefan Tageson
