Phil, Are the systems running the same version of StorageFoundation software? Default partition size for Balanced DMP I/O policy, was 2048 till 5.0MP1. But its changed to 512 in VxVM 5.0MP3 for Active Active arrays.
I think this is your answer on the differences in partionsize shown. Regards, Terrie Douglas Sr. Prin.
