Dell服务器常用管理命令总结

准备新版本的 MegaCli-8.07.14-1.noarch.rpm 会把程序安装在/opt下，可以自定义安装目录，例如： rpm
–relocate /opt/=/usr/sbin/ -i MegaCli-8.07.14-1.noarch.rpm 即把安装目录 /opt 替换成 /usr/sbin。

• 1、查看所有物理磁盘信息

# MegaCli -PDList -aALLAdapter #0Enclosure Number: 1Slot Number: 5Device Id: 5Sequence Number: 2Media Error Count: 0Other Error Count: 0Predictive Failure Count: 0Last Predictive Failure Event Seq Number: 0Raw Size: 140014MB [0x11177328 Sectors]Non Coerced Size: 139502MB [0x11077328 Sectors]Coerced Size: 139392MB [0x11040000 Sectors]Firmware state: HotspareSAS Address(0): 0x5000c50008e5cca9SAS Address(1): 0x0Inquiry Data: SEAGATE ST3146855SS     S5273LN4Y1X0

• 2、查看磁盘缓存策略

MegaCli -LDGetProp -Cache -L0 -a0Adapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, DirectorMegaCli -LDGetProp -Cache -L1 -a0Adapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, DirectorMegaCli -LDGetProp -Cache -LALL -a0Adapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, DirectAdapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, DirectorMegaCli -LDGetProp -Cache -LALL -aALLAdapter 0-VD 0: Cache Policy:WriteBack, ReadAheadNone, DirectAdapter 0-VD 1: Cache Policy:WriteBack, ReadAheadNone, DirectorMegaCli -LDGetProp -DskCache -LALL -aALLAdapter 0-VD 0: Disk Write Cache : Disk's DefaultAdapter 0-VD 1: Disk Write Cache : Disk's Default

• 3、设置磁盘缓存策略

缓存策略解释：WT    (Write throughWB    (Write back)NORA  (No read ahead)RA    (Read ahead)ADRA  (Adaptive read ahead)CachedDirect例子：MegaCli -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0orMegaCli -LDSetProp -Cached|-Direct -L0 -a0orenable / disable disk cacheMegaCli -LDSetProp -EnDskCache|-DisDskCache -L0 -a0

• 4、创建/删除 阵列

4.1 创建一个 raid5 阵列，由物理盘 2,3,4 构成，该阵列的热备盘是物理盘 5

MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] -a0

4.2 创建阵列，不指定热备

MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0

4.3 删除阵列

MegaCli -CfgLdDel -L1 -a0

4.4 在线添加磁盘

MegaCli -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0

意思是，重建逻辑磁盘组1，raid级别是5，添加物理磁盘号：1:4。重建完后，新添加的物理磁盘会自动处于重建(同步)状态，这个 时候 fdisk -l是看不到阵列的空间变大的，只有在系统重启后才能看见。

• 5、查看阵列初始化信息
  

5.1 阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。

MegaCli -LDInit -ShowProg -LALL -aALL# 或者以动态可视化文字界面显示MegaCli -LDInit -ProgDsply -LALL -aALL

5.2 查看阵列后台初始化进度

MegaCli -LDBI -ShowProg -LALL -aALL# 或者以动态可视化文字界面显示MegaCli -LDBI -ProgDsply -LALL -aALL

• 6、创建全局热备

指定第 5 块盘作为全局热备MegaCli -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0也可以指定为某个阵列的专用热备MegaCli -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0

• 7、删除全局热备

MegaCli -PDHSP -Rmv -PhysDrv[1:5] -a0

• 8、将某块物理盘下线/上线

MegaCli -PDOffline -PhysDrv [1:4] -a0MegaCli -PDOnline -PhysDrv [1:4] -a0

• 9、查看物理磁盘重建进度

MegaCli -PDRbld -ShowProg -PhysDrv [1:5] -a0

• 查看硬盘信息

    raidlevel=`/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep "RAID Level" | uniq | awk '{print $4}' | cut -b 9-9`    disknumber=`/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep "Drives" | uniq | awk -F ":" '{print $2}'`    disktype=`/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | grep "PD Type" | head -1 | awk -F: '{print $2}'`    diskcapacity=`/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | grep "Raw Size" | head -1 | awk '{print $3}'`    printf "DISK: $disknumber"*"$diskcapacity "GB"$disktype (Raid Level: $raidlevel)\n"
