環境

  • SnapCenter Plug-in for VMware vSphere(SCV)4.x
  • データ保護のソースSVMとデスティネーションSVMでデータLIFのIPアドレスが重複しています(vserver-dr/SVM-DR)。
  • データストアはSMBC(SnapMirror Business Continuity)で使用される

問題

  • SCVバックアップでSnapshotを作成するためにソースSVMではなくデスティネーションSVMを接続しようとするため、ランダムに失敗する
  • SCVジョグログに「ERROR:

[ERR] Failed to run a command New-NcSnapshotMulti
[DBG] ex.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes. 
[DBG] ex.InnerException.Message : Invalid input. Reason: Operation allowed only on Read_Write (RW) volumes.

  • vmcontrol.log エラーが発生する前にNFS LIFで通常と異なるSVMが検出されたことを示します。
