Documentação > Códigos de erros MegaCli

Megacli é o utilitário de linha de comando que provê comunicação com placas controladoras da família LSI. A LSI fornece placas controladoras para hardware Supermicro e Dell, por exemplo.

O problema do MegaCli é que ele não é intuitivo. Isso é um problema, pois a recorrência de falhas de RAID pode ser algo bem baixo, logo, a memorização dos parâmetros se torna bastante difícil. Outro ponto negativo é a saída de tela com erros, pois é feito com códigos, e não mensagens.

A seguir temos a relação de códigos de saída do MegaCli e a respectiva explicação.
