Eu tenho um controlador RAID Adaptec ASR8405 de hardware no qual eu tenho 15 disco RAID6 Array. Um dos discos quebrou e após a substituição o Controlador não atendeu, não iniciou a reconstrução, mas entrou no estado Falha (veja abaixo):

- Pergunta 1: Como faço o dispositivo lógico reconhecer o disco? Eu tenho
tentei novamente no LD, limpe, verifique e inicialize no disco
em si, mas nada ajuda ...
-
Pergunta 2: Existe alguma chance de corrigir isso e recuperar os dados? Eu tenho um backup, mas há mais de 40TB de dados e recuperando isso de backup não será engraçado.
-
Pergunta 3: Existe alguma chance de que, se eu alterar o estado LD para OPTIMAL, eu conserte a si mesmo?
-
Pergunta 4: Alguma outra ideia sobre como corrigir isso?
Muito obrigado antecipadamente por qualquer sugestão!
