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).
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.
To create an LHEA for a running
logical partition using
the HMC, follow
these steps:
- In the navigation pane, open Systems
Management,
open Servers, and click the managed system
on which the logical partition is located.
- In
the work pane, select the logical partition for which
you want to create the LHEA, click the Tasks button,
and select .
- Select the HEA whose resources
you want the logical partition
to use in Choose an HEA to select Logical Ports from.
- In the table that lists HEA physical
ports,
select a physical port whose resources you want the logical partition
to use, and click Configure.
- In the Choose Logical Ports table,
select the logical port (LHEA port) that you want the logical partition
to use.
- Set the logical port to accept packets
with any virtual
LAN ID (VLAN ID) or to accept only packets with specific VLAN IDs.
- If you want the logical port to accept packets with
any VLAN
ID, select Allow all VLAN IDs.
- If
you want the logical port to accept only packets with specific
VLAN IDs, enter each VLAN ID into VLAN to add and
click Add. You can repeat this step to allow
up to 20 VLAN IDs to be accepted on the logical port.
- You can allow or deny operating-system-defined
MAC addresses by choosing from the options in MAC Address
Restrictions.
- To
specify allowable operating-system-defined
MAC addresses, select Specify Allowable O/S Defined MAC
Addresses.
- Click OK.
- Repeat steps 4 through 9 for each additional
physical port whose resources you want the logical partition to use.
- Adjust the values in Timeout (minutes) and Detail
level if necessary and click OK.
When you are done, one or more new Ethernet
adapters will
be visible to the operating system of the logical partition.
