What is a requirement for Live Partition Mobility?
The correct answer is A. The network and disk must be virtual. Live Partition Mobility (LPM) on IBM Power Systems requires that both network and storage resources be fully virtualized so the partition can be migrated between physical hosts without direct hardware dependency.

Why each option
Live Partition Mobility (LPM) on IBM Power Systems requires that both network and storage resources be fully virtualized so the partition can be migrated between physical hosts without direct hardware dependency.
LPM requires both the network adapter and disk to be virtual - using Virtual Ethernet or Shared Ethernet Adapter for network, and vSCSI or virtual Fibre Channel for storage. Physical or dedicated hardware binds the partition to a specific physical server, preventing live migration. Virtualizing both resources allows the HMC to transparently redirect I/O paths during the migration without interruption.
An LHEA provides near-direct hardware access to a physical network port, which ties the partition to a specific server and is incompatible with LPM; a fully virtual network adapter is required instead.
SAN connectivity alone does not satisfy LPM requirements; the storage must be presented virtually (vSCSI or vFC), not merely physically SAN-attached.
A Mover Service Partition is not a defined IBM prerequisite for Live Partition Mobility and is not a real configuration requirement for LPM.
