Re: OS400 DATA MIGRATION

Hi Neil,

Will I have any performance issue or what are the downside apart from even
spread of data, if I don't even out the second RAID set.
Just a thought, what if I leave the 2 4Gig alone on the 10 x 4Gig, create a
new RAID set for 6 x 8.58Gig and add 8.58Gig to the 2 x 4Gig at the bottom
mirrored set.

Thanks,

Dare
