Partition mobility environment

You can learn about each component of the partition mobility environment and its contribution in enabling successful partition mobility. Components of the partition mobility environment include the source and destination servers, the Hardware Management Console (HMC), the source and destination Virtual I/O Server logical partitions, the mobile partition, the networking configuration, and the storage configuration.

Source and destination servers in a partition mobility environment
Two servers are involved in partition mobility that is managed by a Hardware Management Console (HMC). The source server is the server from which you want to move the logical partition, and the destination server is the server to which you want to move the logical partition.
Hardware Management Console in a partition mobility environment
Learn about the Hardware Management Console (HMC) and how you can use its Partition Migration wizard to move an active or inactive logical partition from one server to another server.
Source and destination Virtual I/O Server logical partitions in a partition mobility environment
Partition mobility that is managed by a Hardware Management Console (HMC) requires at least one Virtual I/O Server (VIOS) logical partition on the source server and at least one VIOS logical partition on the destination server.
Live Partition Mobility pseudodevice
The vioslpm0 pseudodevice is created by default when you install Virtual I/O Server (VIOS) Version 2.2.2.0. You can use the attributes of the partition mobility pseudodevice to control active partition mobility operations. The pseudodevice saves the attributes that affect partition mobility operations.
Configuring the VIOS firewall for partition mobility
You must configure the Virtual I/O Server (VIOS) firewall to allow partition mobility before you enable the VIOS firewall.
Mobile partition managed by an HMC in a partition mobility environment
A mobile partition is a logical partition that you want to move from the source server to the destination server. You can move a running mobile partition, or active mobile partition, or you can move a powered off mobile partition, or inactive mobile partition, from the source server to the destination server.
Software applications that recognize partition mobility
Software applications might be designed to recognize and adapt to changes in the system hardware after being moved from one system to another.
Network configuration in a partition mobility environment
In partition mobility that is managed by the Hardware Management Console (HMC), the network between the source and destination servers is used to pass the mobile partition state information and other configuration data from the source environment to the destination environment. The mobile partition uses the virtual LAN for network access.
Storage configuration in a partition mobility environment
Learn about the virtual SCSI and virtual Fibre Channel configuration required for partition mobility that is managed by the Hardware Management Console (HMC).
