ShinobiLayer: Bare Metal ServerにおけるRedundant Power Supplyの確認方法

Last updated at Posted at 2015-04-09

はじめに

SoftLayerでRedundant Power Supplyを購入したので、これが確かに二つ存在しているかどうかの確認をしたいというのが目的です。間違っているかもしれないので、指摘いただければ幸いです。

ipmitoolの確認

Bare Metal Serverにはipmitoolが既に導入されていたので、これを使って確認します。

# which ipmitool
/usr/bin/ipmitool

# ipmitool -V
ipmitool version 1.8.14

Power SupplyタイプのSDR(Sensor Data Record)出力

下記のとおり2つ出力されるので、2電源存在すると思っています。

# ipmitool sdr type "Power Supply"
PS1 Status       | C8h | ok  | 10.1 | Presence detected
PS2 Status       | C9h | ok  | 10.2 | Presence detected

# ipmitool sdr elist | grep -i PS
PS1 Status       | C8h | ok  | 10.1 | Presence detected
PS2 Status       | C9h | ok  | 10.2 | Presence detected

# ipmitool sensor list | grep PS
PS1 Status       | 0x1        | discrete   | 0x0100| na        | na        | na        | na        | na        | na
PS2 Status       | 0x1        | discrete   | 0x0100| na        | na        | na        | na        | na        | na

によると

Sensor Type Sensor Type Code Sensor-Specific Offset Event
Power Supply 08h 00h Presence Detected
01h Power Supply Failure Detected
02h Predictive Failure Asserted

らしい。なので、Presence detectedであれば問題ないんじゃないかと思っています。
