Error: Uplink redundancy degraded on virtual switch "vSwitch1". Physical NIC vmnic3 is down

Hi

Hi we are using VMware- Virtual appliance for our network infrastructure .I was working on the server room tidying the cables  and I have received an email triggered from VMware infrastructure as follows:

Target: ESX-001.domain.local
Stateless event alarm
 
Alarm Definition:
([Event alarm expression: Network Redundancy Degraded] OR [Event alarm expression: Network Redundancy Degraded on DVPorts])
 
Event details:
Uplink redundancy degraded on virtual switch "vSwitch1". Physical NIC vmnic3 is down. Affected portgroups:"NFS".

At the moment the servers are up and running without any problems.
Please let me know if there is a problem , if so where I need to look at to rectify the problem.

Thanks  and  help will be great.

You have a network interface fail, cable might have been pullled out, so your resilience has been lost.

Indeed look at vSwitch1 and one of the uplinks will be down, you probably knocked it out.
Look on the back of the server - one NIC will have no link-lights on, follow that cable, or it thats the end thats out, look for a lose cable :)
