Every so often a server mentions this in the System log:
The Ethernet Team has transitioned from Fully Redundant or Degraded Redundancy to Redundancy Lost due to a failed or degraded team member. Only one team member is currently active and is either OK or Degraded.
User Action
View the Ethernet and Ethernet Team Member status in the HPE Network Configuration Utility (NCU) if you are using Windows Server 2008. For Windows Server 2012 users, view the status with Microsoft teaming Management UI.. View the System Event Log for additional information.
only to announce in the same log a few minutes later
The Ethernet Team has transitioned from Redundancy Lost or Degraded Redundancy to Fully Redundant, due to a failed or degraded team member recovering full functionality. The team and all team members are operating as configured.
There is no obvious reason for this, no cable disconnected, even temporarily, and no switch issues that I am aware of. Does anyone know if this is normal behaviour?
