問題

このメッセージには、ディスク関連の複数のエラーが示されています。
  • 複数のディスクの「書き込み処理中のチェックサムエントリが無効です」
  • 複数のディスクの「整合性のあるラベルセット(CLS)になっていないため、孤立したディスクがあります
  • 複数のディスクの「算出されたプレックス整合性ラベルセット」よりも新しいため、孤立ディスク
  • SyncMirror プレックスでAutoSupportがトリガーされませんでした
  • 「iskown.ownerReservationMismatch」エラーが発生しました
 
次に例を示します。

このエラーが最初に発生した直後にノードがパートナーにテイクオーバーされるのは、ノードがデグレード状態になったためです。
 
例:
 A disk reservation was detected on disk Site01-sw1:2.126L8 at DDMMMYYYY 04:53:51
Ordinarily, this will only occur if the partner node has taken over.
This node will be shutdown.
HALT: HA partner has taken over disk reservations
Uptime: ddhhmmss
System rebooting...
