cluster(1CL) コマンドには、クラスタファイルシステムとそのグローバルマウントポイントに構成エラーがないか /etc/vfstab ファイルを検査するチェックが含まれています。
cluster check は、デバイスやボリューム管理コンポーネントに影響を及ぼすような変更をクラスタ構成に加えたあとで実行してください。
グローバルクラスタのアクティブなメンバーノード上でスーパーユーザーになります。グローバルクラスタのノードから、次の手順のステップをすべて実行します。

次の例は、suncluster という名前のクラスタのノード phys-schost-2 にマウントポイント /global/schost-1 がないことを示しています。レポートは、出力ディレクトリ、/var/cluster/logs/cluster_check/<timestamp>/ に送信されています。
