redhat、クラスターノードのマルチパスは異なる結果を表示します

「RedHatEntrepriseLinuxServer5.6」がインストールされた2つのノードを持つクラスターがあります

それらに対して「multipath-ll」を実行すると、同じ結果が得られません。 「multipathd-k」内で「showpaths」をチェックしましたが、server1のすべてのパスを取得できません。

「server1」はクラスター内のactifノードであることに注意してください。

どうすればこの問題を解決できますか？

よろしくお願いします

これは、サーバー＃1がSANのインターフェイスの1つを認識できないようにするSANゾーニングの問題がある場合、またはサーバー＃1のHBAの1つに問題がある場合に発生するように見えます。
