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
-
In the navigation pane, click the Resources icon .
-
Click All Partitions. Alternatively, click All
Systems. In the work pane, click the server name that has the logical partition.
-
Click View System Partitions. The All Partitions page is
displayed.
-
In the work pane, select the logical partition and click . The Partition Migration window is displayed.
-
Follow the steps in the Partition Migration window.
-
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.
