Exit Code: 0x00

3、添加新的磁盘

# ./MegaCli64 -CfgLdAdd -r0[32:5] WB Direct -a0
说明：
r0: raid0
[32:5]:32为Enclosure Device ID，5为Slot Number
WB Direct：磁盘Write back

4、添加一块带有残余信息的磁盘

# ./MegaCli64 -cfgforeign -scan -a0
There are 1 foreign configuration(s) on controller 0.

Exit Code: 0x00
说明：由于是新插入的盘，而且是块有数据的盘，所有提示有外部配置。
# ./MegaCli64 -cfgforeign -clear -a0
Foreign configuration 0 is cleared on controller 0.

Exit Code: 0x00
# ./MegaCli64 -cfgforeign -scan -a0
There is no foreign configuration on controller 0.

Exit Code: 0x00
说明：清除外部配置信息，清除后再次进行查看
# ./MegaCli64 -CfgLdAdd -r0[32:5] WB Direct -a0
Adapter 0: Created VD 1

Adapter 0: Configured the Adapter!!

Exit Code: 0x00

5、查看Firmware state

# ./MegaCli64 -PDList -aALL -Nolog|grep ‘^Firm‘
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
这里的Firmware state有可能会有类似于“Firmware state: JBOD”状态的

6、关闭JBOD模式

# /opt/MegaRAID/MegaCli/MegaCli64 -AdpSetProp -EnableJBOD -0 -aALL

Adapter 0: Set JBOD to Disable success.

Exit Code: 0x00

7、检查阵列的配置

# /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -LALL -aAll | grep RAID
RAID Level          : Primary-1, Secondary-0, RAID Level Qualifier-0
RAID Level          : Primary-0, Secondary-0, RAID Level Qualifier-0
RAID Level          : Primary-0, Secondary-0, RAID Level Qualifier-0
RAID Level          : Primary-0, Secondary-0, RAID Level Qualifier-0
