Linux查看硬盘型号 2012-04-28 09:52:45 分类： 服务器与存储 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 Adapter #0 Enclosure Device ID: 8 Slot Number: 0 Device Id: 0 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 Raw Size: 140014MB [0x11177328 Sectors] Non Coerced Size: 139502MB [0x11077328 Sectors] Coerced Size: 139392MB [0x11040000 Sectors] Firmware state: Online SAS Address(0): 0x5000c5000506c469 SAS Address(1): 0x0 Connected Port Number: 0 Inquiry Data: SEAGATE ST3146855SS S5133LN1FB9Q Enclosure Device ID: 8 Slot Number: 1 Device Id: 1 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 Raw Size: 140014MB [0x11177328 Sectors] Non Coerced Size: 139502MB [0x11077328 Sectors] Coerced Size: 139392MB [0x11040000 Sectors] Firmware state: Online SAS Address(0): 0x5000c50005071371 SAS Address(1): 0x0 Connected Port Number: 1 Inquiry Data: SEAGATE ST3146855SS S5133LN1F4N6 Enclosure Device ID: 8 Slot Number: 2 Device Id: 2 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 Raw Size: 140014MB [0x11177328 Sectors] Non Coerced Size: 139502MB [0x11077328 Sectors] Coerced Size: 139392MB [0x11040000 Sectors] Firmware state: Online SAS Address(0): 0x5000c5000506b351 SAS Address(1): 0x0 Connected Port Number: 2 Inquiry Data: SEAGATE ST3146855SS S5133LN1FC40 Enclosure Device ID: 8 Slot Number: 3 Device Id: 3 Sequence Number: 2 Media Error Count: 0 Other Error Count: 0 Predictive Failure Count: 0 Last Predictive Failure Event Seq Number: 0 Raw Size: 140014MB [0x11177328 Sectors] Non Coerced Size: 139502MB [0x11077328 Sectors] Coerced Size: 139392MB [0x11040000 Sectors] Firmware state: Online SAS Address(0): 0x5000c5000506cc01 SAS Address(1): 0x0 Connected Port Number: 3 Inquiry Data: SEAGATE ST3146855SS S5133LN1FBKX 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
