Linux查看硬盘型号

请先确定服务器是否有配 RAID。

如果有RAID，请通过对应的RAID管理（监控）工具查看，例如LSI的MegaCli：

# /opt/MegaCli -PDList -aALL

可以看出，一共有4块物理硬盘，型号均为SEAGATE ST3146855SS（希捷）。

如果没有RAID，通过hdparm命令查看即可，步骤如下：

1、通过fdisk -l列出物理硬盘的设备名称

# fdisk -l

Disk /dev/hda: 160.0 GB, 160040803840 bytes

255 heads, 63 sectors/track, 19457 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/hda1 * 1 25 200781 83 Linux

/dev/hda2 26 1069 8385930 83 Linux

/dev/hda3 1070 2113 8385930 83 Linux

/dev/hda4 2114 19457 139315680 5 Extended

/dev/hda5 2114 3157 8385898+ 83 Linux

/dev/hda6 3158 3418 2096451 82 Linux swap

/dev/hda7 3419 19457 128833236 83 Linux

Disk /dev/hdd: 160.0 GB, 160041885696 bytes

255 heads, 63 sectors/track, 19457 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/hdd1 1 19457 156288321 83 Linux

可以看出，共两块硬盘：/dev/hda、/dev/hdd。

2、通过hdparm命令查看指定硬盘的型号

# hdparm -i /dev/hda

/dev/hda:

Model=WDC WD1600BB-22GUC0, FwRev=08.02D08, SerialNo=WD-WMAL94830149

Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }

RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74

BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455

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: device does not report version:

* signifies the current active mode

# hdparm -i /dev/hdd

/dev/hdd:

Model=WDC WD1600BB-00DWA0, FwRev=15.05R15, SerialNo=WD-WMAEK1512278

Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }

RawCHS=16383/16/63, TrkSize=57600, SectSize=600, ECCbytes=74

BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=16, MultSect=16

CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=268435455

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: device does not report version:

* signifies the current active mode

可以看出，/dev/hda的型号为WDC WD1600BB-22GUC0（西数），/dev/hdd的型号为WDC WD1600BB-00DWA0（西数）。

顺便说一下，如果服务器有配RAID，用hdparm查看硬盘信息时就会报错：

# hdparm -i /dev/sda

/dev/sda:

HDIO_GET_IDENTITY failed: Invalid argument
