If your rootvg at your production site is set to "PP SIZE = 256MB" then when the mksysb restore runs it will automatically create the rootvg at the DR server with a PP SIZE of 256mb as long as the disk is not two large to allow that. Why not just leave the disks mirrored on your prod server and use both disks on your DR server and after the mksysb restore just unmirror rootvg and reduce hdisk1 to free up the extra disk?

If the restore from tape for datavg is not working make sure the block size on the tape drive on the DR server is the same as the block size on the tape drive you created the tapes on. This bit me last month during my DR exercise.
