HP HPE VAN SDN Controller 2.7, Administrator'S Manual, Page: 101 / 231

•
A team must consist of 3 controllers.
•
A controller can only be part of one team.
•
All three controllers in a team must be running the same controller software version.
•
The administrator must create the team and the regions.
•
A team requires one IP address for each controller, plus one IP address assigned to the
team as a whole. If the current team leader goes down, the failover process includes keeping
the team IP address active on the new team leader.
•
After a team is created, the controllers will adopt the data of one of the members of the team.
It is recommended that you avoid possible conflicts or data loss by configuring the team
prior to allowing any switch to connect to a controller.
•
A region cannot be created until a team is formed and the team status is active.
•
A controller can be the configured master controller for one region only.
•
All controllers in a team must be active to configure a region, including the master controller
and all slave controllers. If any controller in the team is in a suspended or unreachable state,
then the region configuration operations are disallowed.
•
IPv6 addresses occurring in any region field are not supported and will cause the region to
be ignored.
•
Only OpenFlow 1.3 network devices are supported when the controller is teamed.
•
OpenFlow 1.3 devices must be configured with the IPs of all three controllers in the team.
Team status
You can view your team status from the top banner of the controller UI, see “Viewing team status”
(page 104) .
The team states are:
•
active
All 3 controllers are actively operating. A prerequisite for this state is that all controllers are
able to communicate with each other.
•
unreachable
Any single controller of a team is not able to communicate with the rest of the team members.
This status occurs because of either of the following possible situations:
◦
The
sdnc
service stopped working or a controller is in the process of rebooting.
◦
A network partition occurred and a controller in a team has become separated from the
other team members.
•
unknown
A team status cannot be determined because of either of the following possible situations:
◦
A communication failure with a REST service component occurred.
◦
A network failure caused the controller to be suspended.
Controller status
HPE VAN SDN Controller groups components into categories and those component groups are
initialized in order as the startup sequencer moves through the stages in the startup sequence.
During the operational phase, the OpenFlow port is opened. Core services are the first to be
initialized and they are always active. System Information Service is part of the core services
