*Linuxでハードディスクの温度を測定する [#m7069b8a] Linuxでハードディスクの温度を測定するには、以下のコマンドを利用します。 smartctl ※S.M.A.R.T.(スマート:Self-Monitoring, Analysis and Reporting Technology System) オプションは以下の通り |オプション|意味| |-a|すべての情報を表示する| |-i|ハードディスクのS.M.A.R.T.サポート状況を表示する | |-l|エラーのログを表示する | |-v|温度やシークエラーなどの状況を表示する| これで、以下のように実行すると、ハードディスクの温度が見れます。 # smartctl -a /dev/sda | grep Temp 194 Temperature_Celsius 0x0022 105 086 000 Old_age Always - 38 ちなみに、全表示だと、こんな感じになります。 # smartctl -a /dev/sda smartctl version 5.33 [i686-redhat-linux-gnu] Copyright (C) 2002-4 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD400JD-55MSA1 Serial Number: WD-WMAMAA164789 Firmware Version: 10.01E01 User Capacity: 40,020,664,320 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 7 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Mon Oct 6 15:47:04 2008 JST SMART support is: Available - device has SMART capability.
