一、查看服务器型号
安装dmidecode
yum install dmidecode
1、查看服务器型号、SN信息
# dmidecode -t 1 # dmidecode 2.11 SMBIOS 2.7 present. Handle 0x0024, DMI type 1, 27 bytes System Information Manufacturer: IBM Product Name: IBM System x3650 M4: -[79159NZ]- Version: 0C Serial Number: 06BZCLH UUID: AF399A1C-0C8C-11E4-B599-40F2E92D9F02 Wake-up Type: Power Switch SKU Number: Not Specified Family: System X
二、查看Raid组磁盘状态，SN等 （需要安装MegaCli ，下载地址：http://pan.baidu.com/s/1i4W6ERb ）
1、查看磁盘raid卡厂商
# dmesg | grep -i raid megaraid_sas 0000:16:00.0: PCI INT A -> GSI 34 (level, low) -> IRQ 34 megaraid_sas 0000:16:00.0: setting latency timer to 64 megaraid_sas 0000:16:00.0: irq 89 for MSI/MSI-X scsi0 : LSI SAS based MegaRAID driver scsi 0:0:0:0: Direct-Access IBM ServeRAID M5110e 3.34 PQ: 0 ANSI: 5 scsi 0:0:1:0: Direct-Access IBM ServeRAID M5110e 3.34 PQ: 0 ANSI: 5 scsi 0:2:0:0: Direct-Access IBM ServeRAID M5110e 3.34 PQ: 0 ANSI: 5 scsi 0:2:1:0: Direct-Access IBM ServeRAID M5110e 3.34 PQ: 0 ANSI: 5 md: Autodetecting RAID arrays.
2、查看磁盘物理信息

3、查看所有Virtual Disk的状态（可以查看到raid级别，每个raid对应的硬盘）
RAID Level对应关系：
| RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 | RAID 1 |
| RAID Level : Primary-0, Secondary-0, RAID Level Qualifier-0 | RAID 0 |
| RAID Level : Primary-5, Secondary-0, RAID Level Qualifier-3 | RAID 5 |
| RAID Level : Primary-1, Secondary-3, RAID Level Qualifier-0 | RAID 10 |

或者只查看raid级别
# /opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL Adapter 0 -- Virtual Drive Information: Virtual Drive: 0 (Target Id: 0) Name : RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 Size : 1.086 TB Mirror Data : 1.086 TB State : Optimal Strip Size : 128 KB Number Of Drives per span:2 Span Depth : 4 Default Cache Policy: WriteBack, ReadAhead, Cached, No Write Cache if Bad BBU Current Cache Policy: WriteBack, ReadAhead, Cached, No Write Cache if Bad BBU Default Access Policy: Read/Write Current Access Policy: Read/Write Disk Cache Policy : Enabled Encryption Type : None PI type: Proprietary type Is VD Cached: No Virtual Drive: 1 (Target Id: 1) Name : RAID Level : Primary-1, Secondary-0, RAID Level Qualifier-0 Size : 1.816 TB Mirror Data : 1.816 TB State : Optimal Strip Size : 256 KB Number Of Drives per span:2 Span Depth : 2 Default Cache Policy: WriteBack, ReadAhead, Cached, No Write Cache if Bad BBU Current Cache Policy: WriteBack, ReadAhead, Cached, No Write Cache if Bad BBU Default Access Policy: Read/Write Current Access Policy: Read/Write Disk Cache Policy : Enabled Encryption Type : None PI type: Proprietary type Is VD Cached: No Exit Code: 0x00
3.在线做Raid

7.替换坏掉的模块
/opt/MegaRAID/MegaCli/MegaCli64 -pdreplacemissing -physdrv[12:10] -Array5 -row0 -a0
8.手动开启rebuid
/opt/MegaRAID/MegaCli/MegaCli64 -pdrbld -start -physdrv[12:10] -a0
9.查看Megacli的log
/opt/MegaRAID/MegaCli/MegaCli64 -FwTermLog dsply -a0 > adp2.log

11.关闭Rebuild
/opt/MegaRAID/MegaCli/MegaCli64 -AdpAutoRbld -Dsbl -a0
12.设置rebuild的速率
/opt/MegaRAID/MegaCli/MegaCli64 -AdpSetProp RebuildRate -30 -a0
13.查看某块磁盘重构进度
