前述

很多情况下，我们需要从OS下查询硬盘的SN，来定位硬盘的物理槽位。如：系统下硬盘报错，对于系统下的硬盘的报错是以硬盘的盘符体现的，而这种情况下我们需要知道该盘符对应硬盘的SN和具体的物理槽位以实现故障硬盘的更换。因此，今天将对这个过程做个介绍，我们将介绍常用OS，比如Linux、ESXi下定位硬盘的一些方法。

Linux

几个工具

Sg_inq

This utility by default sends a SCSI INQUIRY command to the given device and then outputs the response. All SCSI devices are meant to respond to a "standard" INQUIRY command with at least a 36 byte response (in SCSI 2 and higher). An INQUIRY is termed as "standard" when both the EVPD and CmdDt (now obsolete) bits are clear.

Stocli

Stocli是broadcom Raid/HBA卡的一个CLI工具，支持Windows/ESXi/Linux多种操作系统，可以实现硬盘信息的一些查询。

smartctl

smartctl controls the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into most ATA/SATA and SCSI/SAS hard drives and solid-state drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests. smartctl also supports some features not related to SMART. This version of smartctl is compatible with ACS-3, ACS-2, ATA8-ACS, ATA/ATAPI-7 and earlier standards (see REFERENCES below).

几种方法

注：SN作为媒介，来参照不同的信息。

ESXi系统

通过esxcli命令直接定位槽位

注：通过esxcli 的命令可以直接定位硬盘的slot槽位，这块需要说明的是硬盘得是JBOD模式。

通过esxcli命令点亮硬盘指示灯定位硬盘槽位

点亮硬盘定位灯

[root@localhost:~] esxcli storage core device set -l locator -d naa.5000c500c14b27bb

关闭硬盘定位灯

[root@localhost:~] esxcli storage core device set -l off -d naa.5000c500c14b27bb

通过stocli和esxcli命令以sas address为媒介配合定位硬盘槽位
