Ursache

PowerPath 錯誤。

在 VPLEX NDU 期間,VPLEX 導向器在返回幾秒鐘後當機。  這暴露了 PowerPath 中與裝置開啟相關的錯誤,導致 PowerPath 發出額外版本。  這個額外版本會導致使用釋放後的狀況和 Linux 核心錯誤。

Lösung

PowerPath 6.1 HF1 和 PowerPath 未來版本已修正此錯誤。

Weitere Informationen

Red Hat 和 PowerPath 工程部門都能夠在實驗室中重新建立獨立於 VPLEX NDU 之外的狀況。  除了客戶回溯追蹤之外,也觀察到幾種不同的緊急回溯蹤跡。
由於釋放後使用的性質,實際的恐慌可以在幾個地方看到。
