需要关注的是,storcli命令执行结果里的DG/VD。
1. DG编号对应的应该是硬RAID创建的先后顺序,这是一个关键信息,因为后面设置热备盘的时候需要用到。
2. VD编号是和硬RAID在操作系统里对应的盘符的关键信息。

MegaCli命令执行结果无法查看到DG,如”Virtual Drive: 2 (Target Id: 2)”中,对应的2为VD编号。

硬RAID设置热备盘分为两种:
1. 全局热备。
2. 针对某个VD的热备。

热备盘设置命令:

MegaCli -PDHSP {-Set [-Dedicated [-ArrayN|-Array0,1,2...]] [-EnclAffinity] [-nonRevertible]} 
     |-Rmv -PhysDrv[E0:S0,E1:S1,...] -aN|-a0,1,2|-aALL

全局热备:GHSP
全局热备比较简单,将要设置热备的磁盘加到对应的adapter就可以,执行如下命令设置:

MegaCli -PDHSP -Set -PhysDrv[14:1] -a0

局部热备:(Dedicated HSP)

MegaCli -PDHSP -Set -Dedicated -Array2 -PhysDrv[14:1] -a0

局部热备里的Array计算比较麻烦,这里就要用到上面提到的DG,要按DG的排序累加,一直累加到要添加热备的VD(要添加热备的VD也要计算)。
1. 默认设Array为-1。
2. 如果是RAID0,1,5,6,则Array加1。
3. 如果是RAID10,50,则Array加2。
4. 如果是RAID0,1,5,6,则返回Array最后计算的值。
5. 如果是RAID10,50,则返回Array-1,Array。
