環境
- Data ONTAP （7-Mode）8.2.5P5
- FAS6250
- 2ノードファブリック接続MetroCluster
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。

Sat May 15 04:51:39 UTC [Node01:diskown.ownerReservationMismatch:warning]: disk Site01-sw2:2.126L12 (S/N SerialNumber) is supposed to be owned by this node but has a persistent reservation placed by node ?? (ID 28600)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
