为了保证服务器上的数据安全，一般阵列卡会做raid5,或者raid6等等。但是这避免不了可能存在某个磁盘损坏的情况。
ESXI 6以前的版本可以用 MegaCli监控raid状态
[root@CTAPACVM2:~] esxcli software vib install -v /tmp/vmware-esx-MegaCli-8.07.07.vib --no-live-install （安装发现有冲突）
[DependencyError]

[root@CTAPACVM2:~] esxcli software vib list | grep MegaCli （查看以前的MegaCli）

cd /opt/lsi/MegaCLI/
./MegaCli -LdPdInfo -aALL （可以得到raid状态）
但是从ESXI 6开始不能再使用MegaCLI监控raid状态
对于LSI的阵列卡官方有远程监控工具 MSM(MegaRAID Storage Manager) 和 VMW-ESX-LSIProvider.

可以看到组成raid5的5个硬盘的状态了
[root@CTAPACVM2:~] esxtop （出现乱码）
