Solução de problemas de IPMI em um servidor centos 6.5. Especificamente, não consigo configurar o gerenciamento web IPMI devido a erros ao tentar trabalhar com as configurações de LAN IPMI.
Recebo o seguinte erro quando digito ipmitool lan print:
[root@]# ipmitool lan print

Quase todas as respostas do google/stackexchange para esses problemas resultam na resposta encontrada aquiipmitool - não é possível encontrar /dev/ipmi0 ou /dev/ipmidev/0, no entanto, este servidor supermicro tem exatamente os mesmos módulos de kernel ipmi carregados que meu outro servidor supermicro, conforme mostrado abaixo:
[root@SERVER_WITHOUT_WORKING_IPMI]# modprobe --showconfig | grep ipmi
alias platform:ipmi_si ipmi_devintf
[root@SERVER_WITH_WORKING_IPMI]# modprobe --showconfig | grep ipmi
alias platform:ipmi_si ipmi_devintf
Portanto, suspeito que este não seja um problema relacionado aos módulos do kernel...
Qualquer ajuda sobre isso é muito apreciada. Observe que este dispositivo está em produção, então tenho que ter cuidado ao “experimentar”. Observe também que sou relativamente novo no Linux (engenheiro de rede aqui).
Obrigado a todos...(este é meu primeiro post!)

Fiz o seguinte:
lsmod | grep ipmi
...e isso mostrou que o módulo ipmi_devintf NÃO foi carregado. Fiz modprobe e carreguei isso e funcionou.
No entanto, ainda não consigo executar ping na interface ipmi, embora tenha verificado a configuração de rede correta <- este é um problema separado que precisarei investigar.
