1.環境の説明:

システム CPU名 IPアドレス メモリ 共有ディスクサイズの追加
セントス7.9 gpfs1 192.168.10.101 2G 20G
セントス7.9 gpfs2 192.168.10.102 2G 20G

2. 共有ハードディスクを構成します。

  • 前提条件: 2 つの仮想マシンがスナップショットを作成していない

  • mds001 ホストの場合:

    • 5G ハードドライブを 5 台追加

      SCSI > 新しい仮想ディスクの作成 > ディスク容量を指定し、すべてのディスク領域をすぐに割り当て、仮想ディスクを単一のファイルとして保存

    • ディスクのプロパティを変更します。

  • mds002 ホストの場合:

    • 5Gハードドライブを5台追加

      SCSI > 既存の仮想ディスクを使用 > ディスク容量を指定し、すべてのディスク領域をすぐに割り当て、仮想ディスクを単一のファイルとして保存 > mds001 ホストの新しく追加されたディスク ファイルを選択

    • ディスクのプロパティを変更します。

  • mds001 および mds002 の仮想マシン ディレクトリで、サフィックス vmx を持つファイルを見つけて、ファイルの末尾に次の内容を追加します。

    scsi1.sharedBus = "virtual"
disk.locking = "false"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
disk.EnableUUID = "TRUE"

3. スクリプトを完成させます。
