Há duas causas diferentes para esse problema:

1. O nome DVS de um dos nós é diferente com os outros nós no mesmo cluster. Isso causa uma disparidade das informações do cluster e não mostra as informações de configuração da NIC na página. 
2. O nome DVS é diferente da parte de host e rede do GQL.
    

Causa 1:  Se esse problema ocorreu, execute o comando abaixo no VxRail Manager para obter todas as informações do nó. Esse comando exibe todas as informações do cluster em JSON Formato.

curl -k -H "Content-Type: application/json" -X POST -u <username>:<Password> --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock -d '{"query":"query {cluster(moid : \"<mob-ID>\") {host{name hardware{systemInfo{serialNumber}}config{virtualNicManagerInfo{netConfig{nicType selectedVnic}}network{proxySwitch{dvsUuid dvsName hostLag{lagKey lagName uplinkPort{key value}}spec{backing{pnicSpec{pnicDevice uplinkPortKey uplinkPortgroupKey}}}uplinkPort{key value}}}}configManager{networkSystem{networkInfo{netStackInstance{name ipRouteConfig{defaultGateway}}}networkConfig{vnic{device spec{ip{ipAddress subnetMask}distributedVirtualPort{portgroupKey}}}}}}} network{moid name backingType config{key type defaultPortConfig{vlan{vlanId}uplinkTeamingPolicy{uplinkPortOrder{activeUplinkPort standbyUplinkPort inherited}}}distributedVirtualSwitch{name moid}}}}}", "variables":null,"operationName":null}' http://127.0.0.1/rest/vxm/internal/do/v1/network/vds/query

No comando, substitua o valor pela interpretação abaixo.

The value of <username>, <Password>, <mob-ID> should be replaced based on the running cluster information.
The "<mob-ID>" is cluster MoRef ID: vc_mob/content/rootFolder/childEntity/hostFolder/childEntity(domain-xx)
The "<username>, <Password>" is VxRail Manager's root credential

Filtre o conteúdo do resultado e compare o dvsName valor dos hosts para identificar o host com nome DVS diferente com outros hosts. (Mesmo o dvsUuid valores dos hosts são os mesmos)  

Corrija o nome DVS do host no vCenter.
 

Causa 2: Execute o seguinte comando e confirme ambas as saídas DVS Os nomes são os mesmos.

curl -s -k --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock -H "Content-Type: application/json" \
-d "$(cluster_moid=$(curl -s --unix-socket /var/lib/vxrail/nginx/socket/nginx.sock \
