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

查看磁盘阵列
armdsp -a vaname 适合VA7xx0系列, 据称其他也可以用 (可用armdsp -i 查ＶＡ NAME)
amdsp -a vaname 适合FC60
arraydsp -a vaname 适合Autoraid
但ＥＶＡ的就只能到ＣＯＭＭＡＮＤ　ＶＩＥＷ里看了。

实在太多，列了一部分。
HP AutoRaid
这边不得不谈到， HP的AutoRaid 方式，这种方式早就被HP应用了，不过还在被使用当中。
AutoRaid方式结合了，Raid 1 和 Raid 5 , 当空间比较多时，采用Raid 1,比较少时采用Raid 5;
此外，还有所谓的Active hot spare, 就是保留一定的空间，做为万一的备份DISK，可以是一块盘，两块盘，或多块盘，也就是有一块盘挂了，另一块Active hot spare马上就能用了;不过，实际上它是分布在所有的Disk上，是一个虚拟的概念。
再看上面的:
