環境

  • SAP HANA 4.6用SnapCenter プラグイン

問題

  • HAアクティブ/パッシブ構成のSAP HANA。アクティブノードのデータはボリューム<volA> に、パッシブ構成のボリューム<volB> にあります
  • バックアップの実行時にアクティブボリュームでSnapshotが作成されます。この例ではvolAに対してSnapshotが作成されますが、保持期間はbot volAとvolBに適用されます
  • 数日後に発生する状況としては、volBがベースラインであるために最後のSnapshotを削除できず、バックアップが警告で終了することが考えられます
 
Remove Snapshot '<snapshot_name>' failed on volume
'<volA>'. This Snapshot copy is currently used as a reference Snapshot copy by one or more
SnapMirror relationships. Deleting the Snapshot copy can cause future SnapMirror operations to fail.
