因為ceph集群的服務器硬盤都是直通的，當我們發現有硬盤存儲壞道需要更換硬盤，但是因為盤序可能不是連續的，無法定位服務器上那塊硬盤是故障的，如果冒然測試可能把正常的硬盤拔出，得不償失，簡單記錄一下定位故障硬盤的思路。
1、硬盤定位思路
適用於故障硬盤亞健康但未離線硬盤
1.1 找到故障硬盤
[root@a01r1n06 ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 3.7T 0 disk
├─sda1 8:1 0 2M 0 part
├─sda2 8:2 0 1G 0 part /boot
├─sda3 8:3 0 62.5G 0 part [SWAP]
└─sda4 8:4 0 3.6T 0 part /
sdb 8:16 0 14.6T 0 disk /public/home/test
1.2 通過smartctl工具找到硬盤的SN號
[root@a01r1n06 ~]# smartctl --all /dev/sdad
smartctl 6.5 2016-05-07 r4318 [x86_64-linux-3.10.0-862.el7.x86_64] (local build)

Smartctl open device: /dev/sdad failed: No such device
[root@a01r1n06 ~]# smartctl --all /dev/sdb
smartctl 6.5 2016-05-07 r4318 [x86_64-linux-3.10.0-862.el7.x86_64] (local build)

1.3 通過陣列卡工具找到對應序列號對應的服務器的槽位號；
Storcli工具安裝
工具安裝移步 -> https://www.xxshell.com/2800.html
通過Storcli找到硬盤solt
篩選硬盤SN找到Slot；
./storcli64 /call /eall /sall show all |grep -5 -i WKD26RCS
1.4 點亮硬盤定位燈更換硬盤
通過./storcli64 /c0/e0/s23 start locate點亮定位燈
2、使用IPMI系統定位硬盤
因為服務器沒有安裝Storcli,其有IPMI系統，通過IPMI系統來定位硬盤
找到對應的硬盤序列號，點擊【定位物理設備】即可
