Quick Start: Add an active/active network configuration for single or multiple logical interconnect groups

This quick start describes how to add an active/active configuration for an enclosure.

Prerequisites

Required privileges: Infrastructure administrator or Network administrator for adding networks.
Required privileges: Infrastructure administrator or Server administrator for changing the server profile configurations.
Two or more supported Virtual Connect interconnects, as listed in the appropriate support or compatibility matrix on the Hewlett Packard Enterprise Information Library.
The enclosures and server blades are added to the appliance.
Follow the recommended naming conventions described in Requirements for an active/active configuration.

Adding an active/active network configuration for single or multiple logical interconnect groups

For each Virtual Connect interconnect module you want to set up as an active/active configuration in the appliance, make configuration changes to the following resources:

Resource Task Description

Networks

Add networks.
- For an enclosure group with a single logical interconnect group:
  1. Add a pair of Ethernet networks for each VLAN you want to connect: one network for the first interconnect module and one network for the second interconnect module using the same VLAN ID.
    
    For example, create Dev101_A and Dev101_B for VLAN ID 101.
- For a multiple logical interconnect group configuration:
  1. Add an Ethernet network to be used in both logical interconnect groups.

On the Networks screen:

For Name, assign names to the networks according to Requirements for an active/active configuration
For Type, select Ethernet.
For VLAN ID, enter the same ID for both networks.
Verify that Smart link is selected.

Logical Interconnect Groups and Logical Interconnects

Create uplink sets.
- For an enclosure group with a single logical interconnect group:
  1. Create a pair of uplink sets to associate the networks with the uplink ports on the interconnect module.
  2. Assign one set of networks to the uplink set that has ports on the first interconnect module. Assign the other networks to the uplink set that has ports on the second interconnect module.
    
    For example, uplink port X5 is defined in both sets: UplinkSet_A for bay 1 and UplinkSet_B for bay 2. Dev101_A is assigned to UplinkSet_A, and Dev101_B is assigned to UplinkSet_B.
- For a multiple logical interconnect group configuration:
  1. Create an uplink set on the first logical interconnect group and an uplink set on the second logical interconnect group with the same networks.

You can either add the networks to existing uplink sets or create new uplink sets for the networks.
Uplinks in each uplink set must be restricted to a single interconnect.
Duplicate VLAN IDs are not allowed in the same uplink set.
For more information, see Logical Interconnects, or see the REST API scripting help for logical interconnect groups and the REST API for the uplink-sets resource.


	NOTE: If you change the name of an uplink set in the Logical Interconnect Groups screen, and then select Actions→Update from group on the Logical Interconnects screen, connectivity is interrupted briefly.

Network Sets

(Optional) Add one or more pairs of network sets. Each set should include only the networks that will be used on the same server profile connection.

For example, create network set DevSet_A for your development Dev_A networks, and create DevSet_B for your development Dev_B networks.

Adding a network to a network set does not require that you take resources offline. You do not need to update server profiles that have connections to the network set.
Duplicate VLAN IDs are not allowed in a network set.
Each network set should have multiple networks.
For more information about network sets, see Network Sets, or see the REST API scripting help for networks and network sets.

Server Profiles and Server Hardware

Power off the server before you edit the server profile.
Edit the server profile to add two connections. Assign one port for the networks or network sets on one module, and assign a different port for the networks or network sets on the other module.

Make sure the networks associated with the uplink ports in the uplink set match the networks assigned to the profile connections in the downlink ports.

For example, Connection1 is LOM1:1-a for DevSet_A, and Connection2 is LOM1:1-b for DevSet_B.
Power on the server.

When adding a connection to the server profile, select the physical port connected to the module with the uplink set containing the networks configured for that connection. Do not select Auto.
For more information about server profiles, see Server Profiles, or see the REST API scripting help for server profiles.
