（1）找到可用硬盘 #blkid
/dev/mapper/centos-root: UUID="903b5955-0ba9-4d76-8cb1-5b9e9d6eb9f2" TYPE="xfs" /dev/sda2: UUID="s61Ldp-VAaR-MwLR-8fa5-wFbQ-ln6l-VZsbkb" TYPE="LVM2_member" /dev/sda1: UUID="1676224e-9c9f-4350-8661-81c229bb2d88" TYPE="xfs" /dev/sdb: UUID="Y5TERc-SgYb-ekxZ-P84E-v1Vz-ESfu-XTWBAD" TYPE="LVM2_member" /dev/sdf: UUID="S6Jmoz-8spp-feJT-dP6g-soVA-iPNW-s91w9a" TYPE="LVM2_member" /dev/sde: UUID="MKgEN6-3k34-JjwE-Np1O-40zZ-zsac-xGsB2T" TYPE="LVM2_member" /dev/sdg: UUID="I7xfJC-C1b5-MC3d-J207-6shC-1JRb-gp32Jg" TYPE="LVM2_member"

(2)找出所有hdd的序列号 shell# smartctl -i /dev/sdc smartctl 7.0 2018-12-30 r4883 [x86_64-linux-3.10.0-957.27.2.el7.x86_64] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org

(3)根据序列号匹配槽位，然后去除可用硬盘，剩下的就是故障硬盘的。 sehll# ./sas2ircu 0 display LSI Corporation SAS2 IR Configuration Utility. Version 5.00.00.00 (2010.02.09) Copyright (c) 2009 LSI Corporation. All rights reserved.
