Linux multipath 1 lun não usando todos os caminhos outros luns OK

1

Um novo lun 50gb foi adicionado ao servidor rhel5.8 linux e fizemos uma varredura para detectar e adicionar. No entanto multipath -ll mostra que o lun 50gb está usando apenas 1 caminho enquanto as antigas luns existentes estão em 2 caminhos.

Fizemos uma recarga multipath, mas ainda assim o caminho não está chegando.
