Deleting a logical interconnect

To delete a logical interconnect, you must remove the enclosure from management.

16.2.4 About logical interconnect groups

A logical interconnect group is associated with an enclosure group and is used to define the logical
interconnect configuration for every enclosure that is added to that enclosure group. Logical
interconnect configurations include the I/O bay occupancy, stacking mode, uplink ports and uplink
sets, available networks, and downlinks.

The logical interconnect group reserves the appropriate interconnect ports for stacking links required
for the stacking mode. For the enclosure stacking mode:

All interconnects in an enclosure are members of the logical interconnect.

Horizontally adjacent interconnects must be the same interconnect type.

Horizontally adjacent interconnects reserve one port per enclosure for internal stacking links,
called East-West links.

Vertically adjacent interconnects reserve an additional port per enclosure for external stacking
links, called North-South links.

The uplink sets portion of the logical interconnect group defines the initial configuration for uplink
sets for each enclosure added to the enclosure group. You can change the uplink sets for a logical
interconnect, and existing enclosures are not affected by changes you make to uplink sets in the
logical interconnect group. If you change the uplink sets for an existing logical interconnect group,
only enclosures that you add after the configuration change are configured with the new uplink
set configuration.

For more information about logical interconnects and the rules for uplink sets, see the online help
for the Logical Interconnects screen.

When you add an enclosure and assign an enclosure group, the appliance creates a logical
interconnect for that enclosure. The logical interconnect it creates matches the configuration specified
by the logical interconnect group that is associated with the enclosure group. When the add
operation completes, the interconnects are fully configured and the networks are available for use
by server profiles.
