Linxu 如何查看NVMe磁盘的序列号呢？下面是我测试过的几种方法。

OS环境：CentOS Linux release 7.8.2003 (Core) 磁盘：/dev/sda是做RAID1的SSD。/dev/nvme1n1、/dev/nvme0n1是NVMe磁盘，没有做RAID。

方法一 lsblk

因为/dev/sda逻辑盘，SERIAL应该只是系统生产的一个ID。

[root@my-host-1 tmp]# lsblk -o name,type,serial /dev/sda NAME TYPE SERIAL sda disk 600508b1001c53f4be54e7bb874d7171 └─data-data lvm

lsblk也是可以看到NVMe磁盘的信息的

[root@my-host-1 tmp]# lsblk -o name,type,serial /dev/nvme0n1 NAME TYPE SERIAL nvme0n1 disk T090FRRV1 方法二 smartctl [root@my-host-1 ~]# smartctl --all /dev/sda smartctl 7.0 2018-12-30 r4883 [x86_64-linux-3.10.0-1127.el7.x86_64] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Vendor: UN Product: LOGICAL VOLUME Revision: 2.30 Compliance: SPC-3 User Capacity: 1,920,326,787,072 bytes [1.92 TB] Logical block size: 512 bytes Physical block size: 4096 bytes Rotation Rate: Solid State Device Logical Unit id: 0x600508b1001c53f4be54e7bb874d7171 Serial number: Device type: disk Local Time is: Wed Jan 6 16:04:23 2021 CST SMART support is: Available - device has SMART capability.

smartctl获取/dev/nvme1n1信息

[root@my-host-1 ~]# smartctl --all /dev/nvme1n1 smartctl 7.0 2018-12-30 r4883 [x86_64-linux-3.10.0-1127.el7.x86_64] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org === START OF INFORMATION SECTION === Model Number: P50D7040B160 Serial Number: T090FRRR6 Firmware Version: 001008N1 PCI Vendor/Subsystem ID: 0x1c5f IEEE OUI Identifier: 0x00e0cf Total NVM Capacity: 4,000,787,030,016 [4.00 TB] Unallocated NVM Capacity: 0 Controller ID: 1 Number of Namespaces: 1 Namespace 1 Size/Capacity: 4,000,787,030,016 [4.00 TB] Namespace 1 Formatted LBA Size: 512 Local Time is: Wed Jan 6 15:17:13 2021 CST Firmware Updates (0x07): 3 Slots, Slot 1 R/O Optional Admin Commands (0x000e): Format Frmw_DL NS_Mngmt Optional NVM Commands (0x0014): DS_Mngmt Sav/Sel_Feat Maximum Data Transfer Size: 32 Pages Warning Comp.

nvme工具提供用于获取NVME设备信息的选项

[root@my-host-1 ~]# wget https://mirrors.aliyun.com/centos/7.9.2009/os/x86_64/Packages/nvme-cli-1.8.1-3.el7.x86_64.rpm --no-check-certificate [root@my-host-1 ~]# rpm -ivh nvme-cli-1.8.1-3.el7.x86_64.rpm

总结：我的环境NVMe磁盘没有做RAID，在做RAID的情况下，系统看到的是逻辑盘，未必可以获取物理磁盘的信息。
