Fusion-IO ioDrive2のデータ完全削除

Posted at

概要

Fusion-IO ioDrive2はESXi 6.7までしか対応していません。
丁度ヤフオクでIntel DC P3605の1.6TB版を購入（二枚目）したため、ioDriveとお別れすべく、データ完全削除コマンドを実行してみました。

検証環境

ioDrive2 PCIe SSD-1.2TB
OS: VMware ESXi 6.7U3

マニュアル

富士通社のマニュアルが公開されていましたので、こちらを参考にしました。

完全削除（クリア）

マニュアルによると、クリアとパージの2つの削除モードがあり、デフォルトではクリアのようです。以下のようにクリアを実行して状態を確認します。
