Disband a Team
Disbanding a team returns the teamed controllers to standalone operation.
Note
Before disbanding a team, delete the region configuration for that team. See
"Delete a Region" on page 66.
1. Acquire an authentication token for the team master. (See step 4 on page 55.)
2. Using the token acquired in the preceding step, execute this cURL command to disband
the team:
curl --noproxy <team-ip> --header "X-Auth-Token:<auth_token>" --fail
-ksSfL --request DELETE --url https://<member-ip>:8443/sdn/v2.0/team
The resulting output includes the following:
{
"success": [
{"ip":"192.168.56.19"},
{"ip":"192.168.56.25"},
{"ip":"192.168.56.25"}]}
Trigger Team master Election
At the time that a team is formed, or if the current team master fails, the priority settings for
the currently active team members determine which member will take over as team master. If
a team master fails and the team subsequetly elects a lower-priority member as the active
team master, the new leader remains as leader even if the former leader returns to operation.
Thus, if an active team member with the highest priority is operating as the team master, but
goes down, a lower-priority team member takes up team leadership. To restore the highest-
priority member to team master, use the following steps to force a team master election.
1. Acquire an authentication token for the team master. (See step 4 on page 55.)
2. Using the token acquired in the preceding step, execute this cURL command to trigger a
new team election:
curl --noproxy <team-ip> --header "X-Auth-Token:<auth_token>" --fail -
ksSfL --request POST --url https://<member-ip>:8443/sdn/v2.0/team/action -
-data-binary "election"
The above cURL command does not output information.
