IBM x3650 M3のハードウェアRAID構成ディスクの1つに障害が発生。VMware ESXiホストを担うこのサーバに MegaRAID Storage Managerは使えず、結局、ターミナルからMegaCliで アラーム音 を 止める ことができました。
RAIDディスク障害アラーム
VMware ESXiホストを担うIBM x3650 M3（関連記事はこちら）のハードウェアRAIDを構成する物理ディスクの1つに障害が発生しました。
図1.x3650M3 ディスク障害発生
あいにく予備ディスクは無く、交換ディスク手配まで時間が掛かりそうなので、けたたましく鳴り続けるアラーム音を止める方法を探します。
IBM x3650M3のIMMでは
IBM x3650M3のIMM (Integrated Management Module) は、M2よりはマシと言う程度の機能しか実装されておらず、IMMのWebUI上で本件に関してできることは、何か異常が発生していることと、
図2.IMM システムの状態
その内容がディスク異常であることと、その発生時刻の確認まででした。

MegaRAID Storage Managerなら
管理ソフトウェアのMegaRAID Storage Manager（関連記事はこちら）が使えれば、 Physical タブにてコントローラを右クリックのメニューから、アラームの有効無効を制御することができます。
図4.MSM コントローラのアラーム無効化
ただ、MegaRAID Storage ManagerとVMware ESXiの相性が芳しくなく、以前より何度か挑戦するも情報量が少ないこともあり、ESXiホスト内のコントローラへのアクセスはうまくいったことがありません。
MegaCliのでビープ音停止
MegaRAIDコントローラ管理用CLIであるMegaCliのチートシートのようなKBの中に、アラームを無効化するおまじないを見つけました。
幸い、ESXiホスト構築時にMegaCliをインストール済でしたが、未導入の場合はvibをダウンロードし、 esxcli コマンドでインストールします（インストール後はホストの再起動が必要になるので、この手のvibはホスト構築時に導入を済ませておいた方が良いでしょう）。

図5.ESXi 導入済パッケージ一覧
ESXi Host Client上でSSHサービスを有効にしたら、ターミナルでESXiホストに入ります。

MegaCliのいるところまで辿り、コマンドを実行すると、即アラームは鳴り止みました。

MegaCliの基本コマンド
せっかくなので、MegaCliでRAIDコントローラの情報をいくつか取得してみます。

文法にとてもクセのあるCLIですが、サーバ管理には便利に使えそうです。
