一、先安装megaCLI
先下载软件：https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/8-07-10_MegaCLI_Linux.zip
或者直接wget到服务器上，进行解析安装
unzip 8-07-10_MegaCLI_Linux.zip cd 8.07.10_MegaCLI_Linux/Linux\ MegaCLI\ 8.07.10/ rpm -ivh MegaCli-8.07.10-1.noarch.rpm
二、比如要查询/dev/sdn1对应要更换磁盘的slot 几号盘位
# df -h |grep sdn /dev/sdn1 3.7T 2.1T 1.6T 57% /data8 # ll /dev/disk/by-id | grep sdn1 # 查询设备的wwn号 lrwxrwxrwx 1 root root 10 Dec 5 20:50 ata-ST4000NM0035-1V4107_ZC17H1Q6-part1 -> ../../sdn1 lrwxrwxrwx 1 root root 10 Dec 5 20:50 scsi-SATA_ST4000NM0035-1V_ZC17H1Q6-part1 -> ../../sdn1 lrwxrwxrwx 1 root root 10 Dec 5 20:50 wwn-0x5000c500b21acfcd-part1 -> ../../sdn1 # /opt/MegaRAID/MegaCli/MegaCli64 PDList -aAll -NoLog | grep -C 5 5000c500b21acfcd Enclosure Device ID: 0 Slot Number: 9 Enclosure position: 1 Device Id: 10 WWN: 5000c500b21acfcd Sequence Number: 6 Media Error Count: 0 Other Error Count: 52 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0
grep -A 显示匹配指定内容及之后的n行
grep -B 显示匹配指定内容及之前的n行
grep -C 显示匹配指定内容及其前后各n行
查到硬盘位置为slot 9然后再去更换对应的磁盘既可。
卸载故障硬盘 /opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv[0:13] -a0
# /opt/MegaRAID/MegaCli/MegaCli64 PDList -aAll -NoLog # 用此命令查看 上面命令中 0 和 13 以及 -a0 的对应关系： Adapter #0 Enclosure Device ID: 0 Slot Number: 13
MegaCli64 -PdLocate {[-start] | -stop} -physdrv[E0:S0,E1:S1,...] -aN|-a0,1,2|-aALL
点亮指定硬盘（定位，让磁盘闪灯） /opt/MegaRAID/MegaCli/MegaCli64 -PdLocate -start -physdrv[0:13] -a0 注：磁盘换完后关闭指定硬盘指示灯 /opt/MegaRAID/MegaCli/MegaCli64 -PdLocate -stop -physdrv[0:13] -a0
