HP-UNIX File System&Storage 的一些基本知識(下)

查看磁盤陣列
armdsp  -a vaname  適合VA7xx0系列, 據稱其他也可以用 (可用armdsp -i 查ＶＡ NAME)
amdsp   -a vaname  適合FC60
arraydsp -a vaname 適合Autoraid  
但ＥＶＡ的就只能到ＣＯＭＭＡＮＤ　ＶＩＥＷ裏看了。

實在太多，列了一部分。
HP AutoRaid
這邊不得不談到， HP的AutoRaid 方式，這種方式早就被HP應用了，不過還在被使用當中。
AutoRaid方式結合了，Raid 1 和 Raid 5 , 當空間比較多時，採用Raid 1,比較少時採用Raid 5;
此外，還有所謂的Active hot spare,  就是保留一定的空間，做爲萬一的備份DISK，可以是一塊盤，兩塊盤，或多塊盤，也就是有一塊盤掛了，另一塊Active hot spare馬上就能用了;不過，實際上它是分佈在所有的Disk上，是一個虛擬的概念。
再看上面的:
