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... [More]
