因业务需要, 添加了新的磁盘, 因此需要把磁盘重新整合为 RAID10
参考当前磁盘
[root@hh-yun-compute-131104 ~]# megacli -PDList -aALL | grep 'Inquiry Data:' Inquiry Data: HITACHI HUC109060CSS600 A440KWKR7GHX Inquiry Data: HITACHI HUC109060CSS600 A440KWKN3LRX Inquiry Data: SEAGATE ST600MM0006 B001S0M4JC64 Inquiry Data: SEAGATE ST600MM0006 B001S0M4HTAB
查询磁盘当前状态

重组raid 磁盘方法
#!/bin/bash
rpm -ivh --force --nodeps http://10.199.129.21/vclound/tmp/megacli-8.04.07-2.x86_64.rpm

重组并且同时创建多个磁盘的方法

disktotal=`megacli -PDList -aALL | grep -E "DISK\ GROUP|Slot\ Number|postion:|Firmware\ state:" | grep Slot | awk -F[:\ ] '{print $NF}' | wc -l`
if [ $disktotal -eq 4 ]
then
