前はMegaCliだったものが、いまは違うらしい。
というか、中古で手に入れたサーバにMegaRAID SAS 8708EM2が入ってたので必要になったので確認してみた。
「Support Documents and Downloads」から「Product Family:Legacy RAID Controllers」の「Product:MegaRAID SAS 8708EM2」を選択し、検索。
「Management Software and Tools」にあるが、なぜか「Current」には出てこないので「Archive」を選択。
「MegaRAID Storage Manager (MSM)」はJavaで動くGUIツール。
「StorCLI」もしくは「MegaRAID StorCLI」は、コマンドのみ
「MegaRAID Storage Manager (MSM)」の最新版はMR6.9なのに、StorCLIはMR6.8が最新なのはなぜなのか・・・
rpmからインストールすると、/opt/MegaRAID以下にインストールされる。
実行ファイルは、/opt/MegaRAID/storcli/storcli64 か /opt/MegaRAID/storcli/storcli。
まずは、コントローラのリストを「storcli64 show」で取得

コントローラの番号が判明したので「storcli64 /c0 show」と、コントローラを指定して、詳細を確認。

146GB SAS HDDが３本認識されていて
RAID1で２本、スペアで１本使われている。
バッテリーバックアップユニット(BBU)が入ってる。
ステータスを「storcli64 /c0 /bbu show all」で確認

どうやら、まだ生きている模様。
・・・最初は死んでたんだけど「storcli64 /c0 /bbu start learn」とBBUの状態調査を行わせてしばらく放置したら生き返った感じで・・・
