Merhaba,

Bugün backbone switch faulta geçti ve resetlemek zorunda kaldım (HP 5406zl) ardından ESX hostlarımdan birinden sürekli şu hatayı almaya başladım

Previous Status: Green

New Status: Red

Alarm Definition:

([Event alarm expression: Lost Network Connectivity;
Status = Red] OR [Event alarm expression: Restored network connectivity to
portgroups; Status = Green] OR [Event alarm expression: Lost Network
Connectivity to DVPorts; Status = Red] OR [Event alarm expression: Restored
Network Connectivity to DVPorts; Status = Green])

Event details:

Lost network
connectivity on virtual switch "vSwitch0". Physical NIC vmnic0 is
down. Affected portgroups:"VM Network", "Management
Network".

Hem vmnic0 hemde vmnic1 ard arda kesildi diyor. Fakat ne ping kaybı var nede Vcenter dan kopma vs.

Switchdeki port yerlerini değiştirdim, kabloları değiştirdim fakat sonuç aynı.

Şu linkte şöyle bir yazı okudum :

Cause

These messages are received because the vSwitch or Port Group security policy MAC Address Changes is set to Reject. During virtual machine power-up and vMotion migration, the host may momentarily list the virtual machine's MAC address as 00:00:00:00:00:00
while it is initializing. Very shortly afterward, the virtual machine's
correct MAC address is displayed and the port is unblocked. This occurs
so quickly that it has no adverse effects on the virtual machine in
question.

Resolution

These messages can be safely ignored.

Although
the messages indicate that one or more vmnics are down, this is only
from the virtual machine's perspective and does not indicate that the
physical vmnic is down on the host.

Note: This should not be confused with the message, Uplink redundancy restored on dvPorts: "dvPort1". Physical NIC vmnic1 is up, which indicates that a link is up after a down event.

Similar events and log messages can occur for other reasons. For more information, see Uplink redundancy restored on DVPorts events for specific virtual machine Dvports (1032895).

gerçekten sizcede doğrumudur? Göz ardı etmem gereken bir hata mıdır?

Merhaba bu uyarının nedenini biliyorsunuz. Burada siz backbone'u restart ettiğinizde ESX üzerindeki virtual swich'in fiziksel bağlantısının koptuğunu söylüyor. Event log olarak düşmüş. Sürekli tekrar etmemesi gerekiyor.Eğer öyle ise fiziksel network'de devam eden bir sorun olabilir.
