Primary team manager failure
The controller that is designated as the team manager on the Controllers > [team-
manager] >> Management > Teaming page is called the primary team manager.
If the primary team manager becomes inoperative, an interim team manager is automatically
selected by the existing team members. The interim manager assumes the team IP address
and all management functions until the primary team manager returns, with the following
limitation: the interim manager cannot modify the configuration or update the firmware for
members. This is done to avoid the situation where configuration changes made by interim
manager are undone by the primary manager when it comes back online.
When an interim manager is active, the Teaming status light in the Summary box will be
yellow.
All configurable settings on the menus in the right pane will be grayed out. Status information
however, will be visible.
Replacing the team manager
If the primary team manager has failed and will not be returning, you can promote the interim
manager to primary so that configuration options will be available.
Important Once you promote the interim manager to primary manager, you cannot return the old team
manager to the team without changing its configuration so that it becomes a team member.
Only one manager is supported per team.
1. Under Controllers, select the team manager (which is now the interim manager).
2. In the right pane, select Management > Teaming.
