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
