4.7.6.2 rocelinkinfoを使用したRoCEネットワーク・ファブリックのスキャン
rocelinkinfoは、RoCEネットワーク・ファブリックをスキャンし、各リンクのリアルタイム・ステータス情報を表示します。出力は、Linuxのiblinkinfoコマンドの出力と同じ形式を使用して表示されます。
入力なしでrocelinkinfoを実行すると、ユーティリティを実行しているホストに接続されているRoCEネットワーク・ファブリック・スイッチが自動的に検出されます。あるいは、コマンドラインでスイッチ名のカンマ区切りリストを指定して、スキャンする特定のRoCEネットワーク・ファブリック・スイッチを識別することもできます。いずれの場合も、ユーティリティを実行しているホストと、スキャン対象のRoCEネットワーク・ファブリック・スイッチの間でSSHの同等性を構成しておく必要があります。
次に、rocelinkinfoの出力例を示します。この例では、ターゲットExadataシステムは、2つのデータベース・サーバー、3つのストレージ・サーバーおよび2つのRoCEネットワーク・ファブリック・リーフ・スイッチで構成されています。出力例には、configure_roce_hostinfo.shを実行して以前に作成したリンクの説明も含まれています。
