Windows Server2003サーバの仮想化

下記の問題を解消すべく、NetAppでゲストOSの初期オフセットサイズを修正した場合になります。

１から学ぶVMware on NetApp
第八回：古いゲストOSを使用する場合の落とし穴―
「アライメントの重要性」についてご存じですか？

1.mbralignツールをダウンロード
VMware vSphere Clientを起動してからESXiホストを選択し、NetAppタブ内にあるDownloadボタンを押して
mbrtools_esxi.tgzファイルをダウンロード

mbrtools_esxi.tgzファイルをダウンロード

2. ESXiホストでmbralignツールを展開
ESXiホストにSSH接続した後、tarコマンドでmbrtools_esxi.tgzを展開するんですが
/opt/ディレクトリに展開しておかないと、コマンドが失敗します。

3. 対象のゲストOSをシャットダウン(電源停止)
今回の方法ではオンラインで実行できません。
効果は一時的なものになりますが、オンラインでやりたい方はOptimization and Migration機能を調べてください。

4. ゲストOSの初期オフセットサイズを修正
コマンドの実行はフルパス指定で。

# /opt/ontap/mbralign /vmfs/volumes/vol01/HOGE-Server/HOGE-Server.vmdk

WARNING: This version of mbralign is intended for ESXi configurations only.
ESX servers that provide a supported console should use the mbralign
that is included in the latest ESX Host Utilities.

This version does not support Windows drive letter re-mapping. It can
only align one vmdk file at a time.

Since this program will not check for space before creating a new vmdk
file of approximately the same size as the original, always check if enough
free space is available in the datastore before running mbralign.

The Virtual Machine must be powered off before running mbralign against
the vmdk file

A backup file of the vmdk file will be created and stored in the datastore
alignment occurs in. If an error occurs, manually restore the vmdk file with
the backup.

NOTICE:
This tool does not check for the existence of Virtual Machine snapshots or linked clones.
The use of this tool on a vmdk file that has a snapshot or linked clone associated with it
can result in unrecoverable data loss and/or data corruption.
Are you sure that no snapshots/linked clones exist for this vmdk? (y/n)y

5. ゲストOSの起動
Windows OSの場合はすんなり起動してきます。
しかし、1回だけ下記のようにメッセージが出ますのでOSを再起動する必要があります。
