先說明你大概的用途..??

但是我要先說明一點關於SAS expander的問題..
下面這種接法是不允許的:
RAID HBA(initiator; use 2 connectors)<-(connect)->SAS expander<-(connect)->SAS expander

如果要這樣串接...
RAID HBA(initiator; use 1 connector)<-(connect)->SAS expander<-(connect)->SAS expander
維持1:1:1...

During the setup process, I some how lost a hard drive from my old raid 6
你是怎麼丟失你的old RAID array??
你有更換過connector位置??..
這可能會牽涉到OAR/ODR議題..
比較複雜一些..
