    You can use migratepv which will move all data on one phyiscal volume to another. You can also manually mirror and then unmirror all the LVs from one PV to another (mklvcopy, rmlvcopy)

    I have done both of these with my SAP Oracle database online with no problems. It is always better to perform data moves with the application offline, but this is not always possible. When you add HACMP, it only makes it more advisable that the application AND HACMP be down. (Make sure you update your resouce groups within HACMP if you have disks listed rather than VGs)
