問題

  • MetroClusterスイッチオーバーまたはスイッチバック処理が失敗し、 metrocluster operation history次のように表示されます:
Failed to validate the node and cluster components before the switchback operation.
CL02 (non-overridable veto): The Vserver configuration state was set to "degraded" because configuration replication failed. Reason: MetroCluster Vserver stream operation failed. Run the "metrocluster vserver show -configuration-state degraded -fields corrective-action" command to view detailed recovery information. The configuration replication operation will be retried and the Vserver configuration state might change.
  • metrocluster vserver showの出力結果には、失敗の理由が以下のように示されています:
Unrecoverable error during configuration replication, requires manual intervention. Error: Cannot find ports in IPspace "Default" on Node "CL01-N01" for placing LIF "CL01-N01_LIF01" in Vserver "SVM01_CL01".
  • network port showの出力結果から、LIF 用の ipspace Default に利用可能なポートがあることが分かります。
  • イベントログには、以下の内容が記録される場合があります:

[CL01-N01: mgwd: misconfig.lif.info.lost:notice]: LIF "CL01-N01_LIF01" in Vserver "SVM01_CL01-mc" incorrectly placed needs manual recovery. Reason: "MetroCluster DR node "CL01-N01" is offline. The LIF "CL01-N01_LIF01" belonging to Vserver "SVM01_CL01-mc" will be placed on the HA partner node "CL01-N02".".
