Linux 用指令找硬碟
一般來說可以用 ledctl 指令就可以達成找硬碟的動作了。不過在使用前必須啟動 ledmon 服務
[root@liho ~]# systemctl enable ledmon
Created symlink /etc/systemd/system/multi-user.target.wants/ledmon.service → /usr/lib/systemd/system/ledmon.service.
[root@liho ~]# systemctl start ledmon然後用下列指令打開LED燈號及關閉LED燈號
[root@liho ~]# ledctl locate=/dev/sda
[root@liho ~]# ledctl locate_off=/dev/sda不過有些情況是無法透過上面的方式正常運作，也許要改用下列兩種工具：
ssacli – Smart Storage Adminstrator CLI
storcli – StorCli SAS Customization Utility
也許可以在 HPE 下載：https://downloads.linux.hpe.com/sdr/repo/mcp/centos/8/x86_64/current/ 、 https://downloads.linux.hpe.com/sdr/repo/mcp/centos/7/x86_64/current/
如果是使用 ssacli 指令，尋找硬碟的方式如下：（把 X 替換成你的設備數值）
[root@liho ~]# ssacli ctrl slot=X ld X modify led=on
[root@liho ~]# ssacli ctrl slot=X ld X modify led=off如果是使用 storcli 指令，尋找硬碟的方式如下：（把 X 替換成你的設備數值）
[root@liho ~]# storcli /cX/eX/sX start locate
[root@liho ~]# storcli /cX/eX/sX stop locate或是可以參考我寫的 led_ctrl.sh 如下：
