•Logical Interconnects and Logical Interconnect Groups. For a server connected to a logical interconnect to access a network, the logical interconnect must have an uplink set that includes a connection to that network:

◦

◦

You might need to update multiple logical interconnects.

You can make configuration changes to the logical interconnect group, and then update each logical interconnect from the group.

◦If your configuration changes include deleting an uplink set or changing the name of an uplink set, server profile network connectivity can be affected. See “Configuration changes that require or result in resource outages” (page 85).

•Server Profiles. If the server profile does not have a connection to a network set that includes this network, you must add connections to the network.

For a summary of the tasks you complete when adding a network, see “Quick Start: Adding a network to an existing appliance environment” (page 95).

8.2.2 Adding an enclosure

When you add an enclosure to the appliance, you might need to make configuration changes to the following resources:

•Enclosures. Add the enclosure.

•Enclosure Groups. Every enclosure must be a member of an enclosure group. If you do not choose an existing enclosure group, you must create one when you add the enclosure.

•Logical Interconnects and Logical Interconnect Groups. Logical interconnects and logical interconnect groups define the network connectivity for the enclosure. Enclosure groups must specify a logical interconnect group. When you create an enclosure group, if you do not specify an existing logical interconnect group, you must create one. For a server connected to a logical interconnect to access a network, the logical interconnect group you create must have an uplink set that includes a connection to that network.

•Server Profiles. Adding and assigning server profiles to the server blades in the enclosure is not required at the time you add the enclosure, but to use the server blades in an enclosure, you must assign server profiles to them. To access a network, the server profile must include a connection to that network or a network set that includes that network.

For a summary of the tasks you complete when adding an enclosure and connect its server blades to data center networks, see “Quick Start: Adding an enclosure and connecting its server blades to networks” (page 99).
