ShinobiLayer: Bare Metal ServerでRAID構成を確認する(Adaptec編)

はじめに

東京DCのような新しいDCでRAIDを構成する際には、現在LSI MegaRAIDが選択されます。

他のDCでは、AdaptecのRAID CARDが選択されることがあります。ここでは、Adaptecでの構成を確認したいと思います。以下のKnowledgeLayerの記事も併せてご確認下さい。
http://knowledgelayer.softlayer.com/procedure/how-do-i-check-health-my-adaptec-raid-array-linux

1. IPMIを使ったAdaptec RAID Configuration Utilityによる確認例

  1. この画面でCtrl + Aを押す

  2. まずはDISK数の確認
    shinobilayer002.jpg

  3. 3つDISKが存在することが分かる。

  4. Escapeで前に戻って、RAID構成を確認する。

  5. Dev00とDev01のRAID1構成であることが分かる。

2. コマンドによる確認例

1. OSコマンドでRAID Controller情報の確認する

# lsblk

├─sda1   8:1    1  256M  0 part /boot
├─sda2   8:2    1    1G  0 part [SWAP]
└─sda3   8:3    1  1.8T  0 part /

# parted -l

2. arcconfコマンドでRAID環境概要を確認する

# /usr/Adaptec_Event_Monitor/arcconf getversion
Controllers found: 1
Controller #1
==============
Firmware           : 5.2-0 (18950)
Staged Firmware    : 5.2-0 (18950)
BIOS               : 5.2-0 (18950)
Driver             : 1.2-0 (30300)
Boot Flash         : 5.2-0 (18950)


Command completed successfully.

SoftLayerの時計マークが消えてOSログインした際には、まだ以下のようにRAIDはBuild中でした...

# /usr/Adaptec_Event_Monitor/arcconf getstatus 1
Controllers found: 1
Logical device Task:
   Logical device                 : 0
   Task ID                        : 100
   Current operation              : Build/Verify
   Status                         : In Progress
   Priority                       : High
   Percentage complete            : 59


Command completed successfully.

こちらは更に待った後の状態。無事にBuildは終了している。

# /usr/Adaptec_Event_Monitor/arcconf getstatus 1
Controllers found: 1
   Current operation              : None

Command completed successfully.

以下より、Device#0とDevice#1からRAID1が構成されていることが分かる。

# /usr/Adaptec_Event_Monitor/arcconf getconfig 1
Controllers found: 1
