問題

  • SVM DR関係の再同期が失敗し、「Broken-off」状態になっている
  • このSVM DRのコンスティチュエントSnapMirror関係は 「Broken-off」状態です
  • SNAPMIRROR.XML では、SVM DR 関係にLast Transer Type 「resync」と  Last Transfer Error が設定されています。

Transfer for volume "dest_vol" failed. Reason: A Snapshot copy with the name "snapshotName" already exists on destination volume "dest_svm:dest_vol". Execute "snapmirror show -destination-vserver dest_svm -fields last-transfer-error,unhealthy-reason -expand" to check if the constituent volumes have encountered errors.

  • Last Transfer Error で指定されているSnapshotの 所有者タイプは「SM」です
