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.
