Migrating a logical partition

You can use the migration function on the Hardware Management Console (HMC) to migrate a logical partition. If you are using HMC V9.1.930, or earlier, you cannot migrate a logical partition that is configured with Single Root I/O Virtualization (SR-IOV) logical ports. If you are using HMC V9.1.940, or later, and when the firmware is at level FW940, or later, you can migrate a logical partition that is configured with SR-IOV logical ports.

About this task

To migrate a logical partition from one server to another server by using the HMC, complete the following steps:

Procedure

  1. In the navigation pane, click the Resources icon The icon represents the Resources function of the HMC.
  2. Click All Partitions. Alternatively, click All Systems. In the work pane, click the server name that has the logical partition.
  3. Click View System Partitions. The All Partitions page is displayed.
  4. In the work pane, select the logical partition and click Actions > Mobility > Migrate. The Partition Migration window is displayed.
  5. Follow the steps in the Partition Migration window.
  6. In the Migration Information section, you can use the Only migrate SR-IOV logical ports when possible option to migrate a logical partition that is configured with SR-IOV logical ports.
    • When the Only migrate SR-IOV logical ports when possible check box is enabled, the HMC performs the following task:
      • The HMC fails the migration operation if the HMC cannot find an SR-IOV physical port to re-create any of the source SR-IOV logical ports that are migratable before the client logical partition is moved to the destination system.
      • If the client logical partition is already moved to the destination system and if the re-creation of the migratable SR-IOV logical ports on the destination system fails, the HMC does not move the client logical partition back to the source system. You can dynamically add the migratable SR-IOV logical ports on the client logical partition after the migration operation completes.
    • When the Only migrate SR-IOV logical ports when possible check box is disabled, the HMC performs the following task:
      • The HMC does not fail the migration operation even if the HMC cannot find an SR-IOV physical port to re-create any of the migratable SR-IOV logical ports on the source system. Also, the HMC does not attempt to re-create those SR-IOV logical ports. You can dynamically add the migratable SR-IOV logical ports on the client logical partition after the migration operation completes.
    Note: When the HMC is at Version 9.1.940.x, and when the firmware is at level FW940, the Migratable option for the Hybrid Network Virtualization capability is available as a Technology Preview only and is not intended for production deployments. However, when the HMC is at Version 9.1.941.0, or later, and when the firmware is at level FW940.10, or later, the Migratable option for the Hybrid Network Virtualization capability is supported.
  7. Complete the steps in the Partition Migration window, and click Finish.
  8. In the Validation Errors/Warnings section, you can view the error message information that helps you to troubleshoot the configuration problems.
    • Click All Messages to view the warnings and error messages along with the verbose log information about the migration operation. The log information also includes data about successful and failed steps.
    • Click Step Results to view the log information about the migration operation. The log information also includes data about successful and failed steps.
