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：

、通过fdisk -l列出物理硬盘的设备名称

# fdisk -l
Disk /dev/hda: 160.0 GB,  bytes
 heads,  sectors/track,  cylinders
Units = cylinders of  *  =  bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *                                Linux
/dev/hda2                                Linux
/dev/hda3                              Linux
/dev/hda4                            Extended
/dev/hda5                         +    Linux
/dev/hda6                              Linux swap
/dev/hda7                           Linux
Disk /dev/hdd: 160.0 GB,  bytes
 heads,  sectors/track,  cylinders
Units = cylinders of  *  =  bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/hdd1                              Linux

可以看出，共两块硬盘：/dev/hda、/dev/hdd。

、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=.02D08, SerialNo=WD-WMAL94830149
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=//, TrkSize=, SectSize=, ECCbytes=
 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=, MultSect=
 CurCHS=//, CurSects=, LBA=yes, LBAsects=
 IORDY=on/off, tPIO={min:,w/IORDY:}, tDMA={min:,rec:}
 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=.05R15, SerialNo=WD-WMAEK1512278
 Config={ HardSect NotMFM HdSw>15uSec SpinMotCtl Fixed DTR>5Mbs FmtGapReq }
 RawCHS=//, TrkSize=, SectSize=, ECCbytes=
 BuffType=DualPortCache, BuffSize=2048kB, MaxMultSect=, MultSect=
 CurCHS=//, CurSects=, LBA=yes, LBAsects=
 IORDY=on/off, tPIO={min:,w/IORDY:}, tDMA={min:,rec:}
 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
