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:
- 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.
- 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.
- 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.
- 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:
- In the navigation area, select View/Modify Partitions under Partition
Management. The View/Modify Partitions
page is displayed.
- Select the client logical partition that you want to migrate.
- From the Tasks menu, click Migrate. The Migrate Partition page is displayed.
- Specify the required information and click Validate.
- If you receive validation errors, fix the errors and return
to this page.
- When you verify that there are no validation errors, click Migrate.
