Two POWER6 or POWER7 systems controlled by the same Hardware Management Console (HMC).

The destination system must have enough CPU and memory resources to host the mobile partition.

The migrating partition must use the virtual LAN (VLAN) for all LLT links and public network access. The VLAN must be bridged to a physical network using a shared Ethernet adapter in the Virtual I/O Server partition. If there is more than one VLAN, each VLAN must be bridged.

The Virtual I/O Servers on both systems must have a shared Ethernet adapter configured to bridge to the same Ethernet network used by the mobile partition.

Your LAN must be configured such that migrating partitions can continue to communicate with the other nodes after a migration is completed.

The operating system, applications, and data of the mobile partition must reside on virtual storage on an external storage subsystem since the mobile partition's disk data must be available after the migration to the destination system is completed. An external, shared access storage subsystem is required.

The mobile partition's virtual disks must be mapped to LUNs; they cannot be part of a storage pool or logical volume on the Virtual I/O Server. The LUNs must be zoned and masked to the Virtual I/O Servers on both systems.
