Migrating a client logical partition to another managed system

You can use the Integrated Virtualization Manager to migrate an inactive or a running client logical partition to another system managed by another Integrated Virtualization Manager.

You can migrate AIX® and Linux logical partitions between IBM® Power Systems™ servers, between IBM BladeCenter® blade servers with Power Architecture® technology, or between IBM Power Systems servers and IBM BladeCenter blade servers with Power Architecture technology.

For information about specific POWER7® models that support partition migration, see Preparing the source and destination servers for partition mobility.

Note: Migration of IBM i logical partitions is not supported.

You cannot migrate the management partition.

Before you start to migrate a client logical partition, complete the following tasks:
  1. Ensure that the PowerVM® Enterprise Edition is enabled on both the source managed system and the destination managed system. For instructions, see Entering the activation code for PowerVM Editions with the Integrated Virtualization Manager.
  2. Ensure that you have properly prepared the source managed system, the destination managed system, and the migrating partition for the migration. For instructions, see Preparing for Partition Mobility.
  3. Ensure that the source managed system and the destination managed system meet the following requirements:
    • Ensure that the destination managed system and the source managed system have compatible firmware, processors, and logical memory block (LMB) size (the smallest chunk of memory that can be assigned to a partition).
    • Ensure that all required external I/O devices are connected to the migrating partition through the Integrated Virtualization Manager or Virtual I/O Server. The destination managed system and the source managed system must have common access (SAN and LAN) to the same disks and networks. The destination managed system must have sufficient resources available to host the migrating partition.
    • Ensure that the source managed system and destination managed system are at the appropriate hardware levels and are compatible for partition migration.
    • Ensure that the source managed system and destination managed system each have at least one Integrated Virtualization Manager or Virtual I/O Server logical partition that provides virtual SCSI and virtual Ethernet to the migrating partition.
    • Ensure that the source managed system and destination managed system provide compatible virtual SCSI configurations.
    • Ensure that the source managed system and destination managed system provide compatible virtual Ethernet configurations.
    • Ensure that the source managed system and destination managed system provide compatible virtual fibre channel configurations.
    • If you are migrating a partition that uses shared memory, the destination managed system must meet these additional requirements to migrate a shared memory partition:
      • A memory pool must exist on the destination managed system.
      • The memory pool on the destination managed system must have sufficient space for the I/O entitled memory value that is currently specified for the migrating partition.
      • The memory pool on the destination managed system must have a paging space device of an appropriate size for the migrating partition, or the IVM on the destination system must be able to create an appropriate paging space device. For AIX and Linux migrating partitions, the paging space device must be at least as large as the maximum memory size of the migrating partition.
    Note: This is not a complete list of requirements. For more detailed information about partition migration requirements for IVM, see Configuration validation for Partition Mobility. .
  4. Retrieve the IP address or host name of the IVM that manages the system to which you plan to migrate the partition.

To migrate a client logical partition to another managed system, complete the following steps in the Integrated Virtualization Manager:

  1. In the navigation area, select View/Modify Partitions under Partition Management. The View/Modify Partitions page is displayed.
  2. Select the client logical partition that you want to migrate.
  3. From the Tasks menu, click Migrate. The Migrate Partition page is displayed.
  4. Specify the required information and click Validate.
  5. If you receive validation errors, fix the errors and return to this page.
  6. When you verify that there are no validation errors, click Migrate.
To view the progress of the migration, see Viewing or modifying the status of a migrating partition.
