由于服务器的BIOS未集成Optional rom，所以无法在BIOS下图形化设置Raid，
只能在OS下用工具MegaCli
1. #查看磁盘信息
[root@localhost ~]# megacli -PDList -aALL |egrep 'Adapter|Enclosure|Slot|Firmware state'
Adapter #0
Enclosure Device ID: 252
Slot Number: 4
Enclosure position: N/A
Firmware state: Unconfigured(good), Spun Up
Enclosure Device ID: 252
Slot Number: 5
Enclosure position: N/A
Firmware state: Unconfigured(good), Spun Up
[root@localhost ~]#
2. #组建Raid1
#megacli -CfgLdAdd -r1 [252:4,252:5] WB -a0
根据Enclosure Device ID 252及Slot Number 4 5 组成数据，r1为raid 1 ,a0为Adapter number
组建Raid5
megacli -CfgLdAdd -r5 [41:0,41:1,41:2,41:3,41:4,41:5,41:6,41:7,41:8,41:9,41:10,41:11] WB Cached -a0
[root@localhost ~]# megacli -CfgLdAdd -r1 [252:4,252:5] WB -a0
Adapter 0: Created VD 0
Adapter 0: Configured the Adapter!!
Exit Code: 0x00
3. #查看组建后raid 1的raid卡状态
[root@localhost ~]# megacli -ShowSummary -aALL

4. #查看和开启JBOD模式：
##megacli -AdpGetProp -enablejbod -aALL #查看JBOD是否开启
[root@localhost ~]# megacli -AdpGetProp -enablejbod -aALL
Adapter 0: JBOD: Disabled
Exit Code: 0x00
##megacli -AdpSetProp -EnableJBOD -0 -aALL #关闭JBOD
[root@localhost ~]# megacli -AdpSetProp -EnableJBOD -0 -aALL
Adapter 0: Set JBOD to Disable success.
Exit Code: 0x00
##megacli -AdpSetProp -EnableJBOD -1 -aALL #打开JBOD
[root@localhost ~]# megacli -AdpSetProp -EnableJBOD -1 -aAlL
Adapter 0: Set JBOD to Enable success.
Exit Code: 0x00
5. #Firmware state: Unconfigured(bad)解决办法
megacli -PDMakeGood -PhysDrv[E:S] -a0 固件状态会由Unconfigured(bad)变成Unconfigured(good), Spun Up
[root@localhost ~]# megacli -PDList -aALL |egrep 'Adapter|Enclosure|Slot|Firmware state'
Adapter #0
Enclosure Device ID: 252
Slot Number: 4
Enclosure position: N/A
Firmware state: Online, Spun Up
Enclosure Device ID: 252
Slot Number: 5
Enclosure position: N/A
Firmware state: Unconfigured(bad)
[root@localhost ~]# megacli -PDMakeGood -PhysDrv[252:5] -a0
Adapter: 0: EnclId-252 SlotId-5 state changed to Unconfigured-Good.
Exit Code: 0x00
[root@localhost ~]# megacli -PDList -aALL |egrep 'Adapter|Enclosure|Slot|Firmware state'
Adapter #0
Enclosure Device ID: 252
Slot Number: 4
Enclosure position: N/A
Firmware state: Online, Spun Up
Enclosure Device ID: 252
Slot Number: 5
Enclosure position: N/A
Firmware state: Unconfigured(good), Spun Up
[root@localhost ~]#
6. #查看磁盘rebuild进度
[root@localhost ~]# megacli -PDRbld -showprog -physDrv [252:5] -a0
Rebuild Progress on Device at Enclosure 252, Slot 5 Completed 1% in 2 Minutes.
Exit Code: 0x00
7. #关闭蜂鸣报警
megacli -AdpSetProp AlarmDsbl -aALL #永久关闭，重启后还是关闭
megacli -AdpSetProp -AlarmDsbl –a0 #永久关闭，重启后还是关闭
megacli -AdpSetProp -AlarmSilence –a0 #临时关闭，重启又变成开启
megacli -AdpSetProp -Alarmenbl –a0 #开启
megacli -AdpgetProp -Alarmdsply –a0 #查看告警的状态
8. #清除raid组的配置
megacli -cfgclr -a0 #清除所有的raid组的配置
9. #查看RAID的状态
megacli -LDInfo -Lall -aALL #查看RAID的状态
10. #查看raid卡的信息
megacli -adpallinfo -a0
