MetroCluster のFCスイッチバックが失敗しました

問題

スイッチバックの失敗が原因で次のイベントが生成されます。

[Node-01: notifyd: callhome.mcc.switchback.failed:EMERGENCY]: Call home for METROCLUSTER SWITCHBACK FAILED

MetroCluster のスイッチバックが次のエラーで失敗します。

Cluster-1 (manual recovery required): Some disks were left behind during switchback. They are listed along with a reason for failure: 4.27.1 (not responding)

If any of these disks are failed, replace them. Otherwise use the "metrocluster switchback" command again to return the disks to their original owner. Use the "storage disk show -dr-home-id !- -fields dr-home, container-type, aggregate" command for more details on the status of the left-behind disks.
