Eu tenho um 3ware 9750-4i com 36 unidades em execução (4 no RAID 10, unidades individuais de descanso, ou seja, JBOD).
Quando eu reinicio, todas as unidades, exceto a matriz RAID 10, têm seus UUIDs alterados na reinicialização (parece aleatório, já que reiniciei algumas vezes e cada vez era um UUID completamente diferente). Isso faz com que eu percorra manualmente 32 unidades, descubra onde elas devem ser realmente mapeadas e as remonte lá.
Eu não encontrei nada on-line, mesmo relacionado a esse problema, e sou realmente novo nos cartões RAID em geral. Existe algum tipo de configuração que eu possa estar faltando? Ou talvez algo com o meu kernel causando isso (novamente, também não tenho muito conhecimento sobre kernels)
Editar: executando o Debian 7.6 64bit.
Note que limitei a saída apenas para as primeiras unidades, pois elas são todas iguais.
