如何读取Linux内核磁盘序列号

lrwxrwxrwx 1 root root 9 10月 17 10:11 scsi-SATA_ST3500413AS_Z2A2AGQA ->../../sdb

可以看到，一个磁盘可以用传统的/dev/sdX来索引，也可以by-YY来索引，其中by-id就是以序列号来索引，上述输出中，下划线后面的就是序列号。同样，我们可以用hdparm工具程序来读取，可以读到同样的结果。

LINUX查询工作站多硬盘的硬盘序列号方法：

1、确认安装yaourt hdparm

2、运行下面命令查看共有多少硬盘

[root@myhost detect]# fdisk -l

Disk /dev/sda: 320.1 GB, 320072933376 bytes

255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors

Units = sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

/dev/sda10 126865368 625137344 249135988+ 83 Linux

由上可见，只有一个硬盘sda，其中，sda1到sda10是说该硬盘共有十个分区。

多个硬盘的话会看到sdb、sdc等；

3、查看sda硬盘的序列号，

[root@myhost detect]# hdparm -i /dev/sda

/dev/sda:

Model=ST3320418AS, FwRev=CC66, SerialNo=6VMDEMJM

Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }

RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4

BuffType=unknown, BuffSize=16384kB, MaxMultSect=16, MultSect=16

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=625142448

IORDY=on/off, tPIO={min:120,w/IORDY:120}, tDMA={min:120,rec:120}

PIO modes: pio0 pio1 pio2 pio3 pio4

DMA modes: mdma0 mdma1 mdma2

UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5

AdvancedPM=no WriteCache=enabled

Drive conforms to: unknown: ATA/ATAPI-4,5,6,7

由上可见，sda硬盘的序列号为6VMDEMJM。

同理查看其它硬盘序列号。
