約 2 ヶ月ほど前にリリースされた VMware HCX (以下、HCX) 4.0 にて、下記の通り GUI (vSphere HCX plug-in) 上からマイグレーションのイベント詳細が確認できる機能が追加されています。
今までは HCX のマイグレーション中の動作などが分かりにくいところがありましたが、この機能にてイベントの動作が確認できるため、運用する上で非常に役立つ機能だと思います。今日は、HCX マイグレーションタイプの中でよく使われそうな “vMotion / Bulk Migration / Cold Migration” の 3 種類に対して、上記 GUI で表示されるイベントをまとめたものを共有したいと思います。
注意事項
・本記事では、下記の HCX バージョンにて試したイベント情報を共有してあります。HCX 将来のバージョンにてはイベント内容が異なる場合がありますので、ご注意ください。

・本記事では、HCX マイグレーションタイプの中でよく使われそうな “vMotion / Bulk Migration / Cold Migration” の 3 種類を実際試した (マイグレーション成功時) イベントの共有となります。何らかの理由によりマイグレーションが失敗した場合などは、本記事で紹介しているイベント内容と異なる可能性があります。
