Creating a logical Host Ethernet Adapter for a running logical partition
If your managed system has a Host Ethernet Adapter (HEA), you can set up a logical partition to use HEA resources by using the Hardware Management Console (HMC) to create a logical Host Ethernet Adapter (LHEA) for the logical partition. A logical Host Ethernet Adapter (LHEA) is a representation of a physical HEA on a logical partition. An LHEA allows the logical partition to connect to external networks directly through the HEA. HEAs are also known as Integrated Virtual Ethernet adapters (IVE adapters).
Before you begin
You can add an LHEA dynamically to a running Linux® logical partition only if you install Red Hat® Enterprise Linux version 5.1, Red Hat Enterprise Linux version 4.6, or a later version of Red Hat Enterprise Linux on the logical partition. To add an LHEA to a Linux logical partition with a distribution other than these distributions, you must shut down the logical partition and reactivate the logical partition using a partition profile that specifies the LHEA.
If a logical partition is not currently running, you can create an LHEA for the logical partition by changing the partition profiles for the logical partition.
