Vmware ESXI 6.7 U3
I have 8 ESXI hosts all eight have 8 network adapters I use 6 of them two are spare.
On one ESXI host after a power outage I am getting this error all the time now.
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 DVPorts: "3/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "43/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "175/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "241/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "6/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "176/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "7/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1", "265/50 25 82 a7 f1 90 5f ab-e8 64 c2 89 ea 8f 47 a1". Physical NIC vmnic0 is down.
The Physical NIC has the primary IP address of the host.
I activated one of my Spare Network adapter but I can not figure out home to swap the VMNIC0 with VMNIC7
Any suggestions ?
Thank you
hey,
Physical NIC doesn't have any IP address , it has hardcoded Mac address , layer 2 device
Now you need to remove uplink
Add uplink
At this point vmk0 [management kernel] will be using some other vmmic and not vmnic0 , thus you can safely do it .
I am unable to remove VMK0
Remove an Uplink from a vSphere Distributed Switch (vmware.com) This helped from one place but not from this place.
Need to remove this so I can assign ip address to VMK7
No need to remove vmk0 , its vmkernel on host
just remove vmnic0 and add vmnic 7 as uplink
Harry
When I do that I loss connectivity to the ESXI host all VMS become disconnected.
Any screen shots of the best method would be helpful
Thanks
Tom
Run these commands
esxcfg-vswitch -l
esxcfg-nics -l
esxcfg-vmknic -l
Also type esxtop and press "n" and provide screenshot

Are your VMs TGCS035 and TGCS026 currently up and running .
You can ping them and reach out them?
I can see the dvs -management already has three uplinks vmnic0, vmnic1 vmnic7
if those vms are reachable , i would suggest them to vmotion to some other host . Once done repeat esxtop "n" and send screenshot
Hey @insearchof,
Regarding the Teaming and Failover policy of the Management portgroup where the vmk0 is connected, you need to check that the vmnic7 is Active. If that vmnic is there then you can safely move the vmnic0 to the unused section.
Of course make sure that the physical port where the vmnic7 is connected is configured the same as where the vmnic0 is connected.
Harry
Yes all VMS on the Hosts are up and running and I can ping all I use Nagios to monitor my system and I would be alerted if they are not reachable
When vmnic0 goes down sometimes Nagios sends me an alert of a server is down also but it really is not. VMNIC0 stays down for a few seconds then is back online. Very flaky. That's why I want to remove it.
I migrated all VM's off this host and ran esxtop
any ideas
Laegre
When I remove VMNIC0 I loss connectivity to the HOST I can logon to the host directly but I am limited to what I can do there.
I need to be able to make the changes in vcenter if possible.
VMNIC7 is setup as DHCP now I need to make it the same ip address as VMNIC0
IS there a proper method I can use to do this?
Every time I try to make VMNIC7 ip address as VMNIC0 it tells me address is in use
But I am unable to change that address on VMNIC0
at a loss here
