ASM Normal需要3個disk ?

Linux AS 5.3  64bit,   Oracle 11.2.0.2  


看11g 的文件， 寫的ASM redundant 有external , normal , high 三種，分別是1，2，3個冗餘，在虛擬機器器
上測試，的確是選擇normal disk group , 需要兩個磁碟， 但是在實體storage安裝11g RAC的時候， 發現選擇
Normal ASM disk group 的時候， 需要點選 3 個disk 才能通過， 選擇兩個會報錯， 報錯資訊如下圖：

看文件的解釋，貌似11.2 開始， Normal 需要3個，High 需要5個。


Starting with Oracle 11g Release 2, Oracle Universal Installer checks minimum number of ASM disks for ASM disk group to store Voting and OCR disk. so if you are choosing normal redundancy then you have to select minimum three disks OR create your ASM disk group with External redundancy. If you want to use Normal redundancy then you should have at least three ASM disks.
So there is nothing wrong with your installation process and this issue is not related to Suse or I would say it is not an issue at all.
