IDPA: O serviço Node Event está degradado devido a uma rota duplicada 169.254.0.1

Falha de pré-verificação do RUCK firmware_readiness:

[ERROR] Firmware pre-upgrade checks failed. [ 10.100.XX.XXX ]: The cached response with Node Event Service is disabled.
Node Event Service is in a degraded state,iDRAC Service Module is not available/active at this time.
Check iDRAC Service Module/iDRAC status.

Ao executar o comando abaixo, o idraccache apresentará erro ou degradação.

O iSM está em execução, mas não consegue se comunicar com os logs de depuração do iDRAC:

Essa rota extra é criada na camada do sistema operacional do host e com base na configuração de rede existente. Esse comportamento geralmente é visto quando várias rotas estáticas são definidas na configuração do ESXi.

A possível causa inclui o uso de um túnel SSH interno do ESXi para o iDRAC.

O iSM não cria as rotas adicionais nem detecta e corrige quaisquer rotas adicionais definidas.

1. Confirme uma entrada inválida na tabela de roteamento do ESXi, o que impede que o iSM use 169.254.0.2 para se comunicar com o 169.254.0.1 do iDRAC.

Veja abaixo um exemplo de ambiente de rede com esse problema. A vmk0 Endereço de gateway da interface para uma rota extra para a rede 169.254.0.1/32.

[root@idpa-esxi:~] esxcli network ip route ipv4 list
Network         Netmask          Gateway        Interface  Source
--------------  ---------------  -------------  ---------  ------
default             0.0.0.0                10.100.10.254   vmk0       MANUAL
10.100.10.0     255.255.255.0    0.0.0.0               vmk0       MANUAL
169.254.0.0     255.255.255.0    0.0.0.0               vmk2       MANUAL
169.254.0.1     255.255.255.255  10.100.xx.xxx  vmk0       MANUAL
192.168.100.96  255.255.255.224  0.0.0.0          vmk1       MANUAL

2. Remova a entrada para corrigir o problema de roteamento entre o iSM e o iDRAC.

esxcli network ip route ipv4 remove -g 10.100.xx.xxx -n 169.254.0.1/32

3. A entrada foi removida:

[root@idpa-esxi:~] esxcli network ip route ipv4 list
Network         Netmask          Gateway        Interface  Source
--------------  ---------------  -------------  ---------  ------
default             0.0.0.0                10.100.10.254   vmk0       MANUAL
10.100.10.0     255.255.255.0    0.0.0.0               vmk0       MANUAL
169.254.0.0     255.255.255.0    0.0.0.0               vmk2       MANUAL
192.168.100.96  255.255.255.224  0.0.0.0          vmk1       MANUAL

4. Depois que a rota extra for removida, reinicie o PTAgent e o serviço iSM.

/etc/init.d/DellPTAgent restart

/etc/init.d/dcism-netmon-watchdog restart

5. Executar a prontidão do firmware para confirmar o SUCESSO
