使用sas2ircu在TrueNAS Scale中定位坏硬盘
场景描述
长期使用的一个ZFS硬盘阵列出现了硬盘损坏，SMART测试报大量错误。但是由于硬盘安装的时候没有做标记，因此面对12个硬盘位害怕抽错硬盘导致阵列GG。同时阵列正在执行读写和新盘的同步，不太方便停机抽出来看，因此需要在机器运行的时候定位损坏的硬盘。
基本环境
服务器：RH2288H V2
硬盘背板：SAS2308
操作系统：Esxi8直通SAS2308，TrueNAS-SCALE-22.02.4
操作流程
1、通过SSH登录TrueNAS Scale
如果在操作过程中出现`SAS2IRCU: MPTLib2 Error 1`，一般是权限问题，请加sudo或使用root账户。
1 2 3 4 5 6 | admin@truenas[/mnt]$ sas2ircu listLSI Corporation SAS2 IR Configuration Utility.Version 20.00.00.00 (2014.09.18)Copyright (c) 2008-2014 LSI Corporation. All rights reserved.SAS2IRCU: MPTLib2 Error 1 |
2、检查sas2ircu是否能识别阵列卡

3、在TrueNAS Scale上找到发生损坏的硬盘的序列号(Storage -> Disks -> Serial)，是序列号(Serial No)不是硬盘型号(Model Number)。
4、在硬盘信息中找到该硬盘的相关信息
1 2 3 4 5 6 7 8 9 10 | root@truenas[~]# sas2ircu 0 display | grep -B 8 WCC4E3LJFF91 Enclosure # : 2 Slot # : 5 SAS Address : 500e004-a-aaaa-aa05 State : Ready (RDY) Size (in MB)/(in sectors) : 3815447/7814037167 Manufacturer : ATA Model Number : WDC WD40PURX-64G Firmware Revision : 0A80 Serial No : WDWCC4E3LJFF91 |
5、从上述信息中找到Enclosure编号和Slot编号，构成硬盘盘位的编号Enclosure:Slot，例子中即为：2:5
6、使用定位指令与硬盘盘位号让硬盘盘位的知识灯亮起来
1 2 3 4 5 6 7 8 | root@truenas[~]# sas2ircu 0 locate 2:5 onLSI Corporation SAS2 IR Configuration Utility.Version 20.00.00.00 (2014.09.18)Copyright (c) 2008-2014 LSI Corporation.

关灯

7、可以看到机箱上的灯已经亮起（或闪烁）
