Cause

パーティション/data01は250Gですが、他のパーティションは1 TBであるため、使用率が他のパーティションよりも高くなります。Avamarは、同じAVEに異なるサイズのデータ パーティションを持つことをサポートしていません。

これは 4 TB の AVE であるため、6 つのデータ パーティション (それぞれ 1 TB) が必要です。出典: https://www.delltechnologies.com/asset/en-us/products/data-protection/technical-support/docu91853.pdf (「AVE仮想ディスクの要件」、17ページ)

同じページにメモがあります。
"Because the AVE .ova installation creates three 250 GB partitions along with the OS disk, approximately 900 GB of free disk space is required at installation. However, the AVE .ovf installation does not create storage partitions during installation. Therefore only enough disk space for the OS disk is required at installation, and subsequent storage partitions can be created on other datastores"

Resolution

この場合、新しい4 TB AVEを導入する必要があります(6 x 1TBデータ パーティションあり、250GBパーティションなし)。次に、すべてのデータを新しいシステムに複製します。

 

Additional Information

新規導入は、ローカル チームとプロフェッショナル サービスの責任となります。
