Thanks to the IBM
Virtual Loaner Program, I was able to try out my first POWER7 LPAR today.

Paging Device Considerations for AMS ( Active Memory Sharing ) with LPM ( Live Partition Mobility).What are the considerations for paging devices when using Active Memory Sharing (AMS) with Live Partition Mobility (LPM)? Paging devices can only be assigned to one shared memory pool at a time. You cannot assign the same paging device to a shared memory pool on more than one system at the same time. If you accidentally assign a SAN paging device to both the source and destination VIOS, this can result in memory corruption. When data is read from the paging device during the LPM operation or post-migration, when memory is accessed on the destination system. Prior to migrating a shared memory partition ensure that the destination system has an available paging device for the mobile LPAR to use. Refer to the following link for further information.
