Symptoms

此檔案設計符合 PowerVault ME5、ME4 和 MD3 儲存裝置上 Linux 型多路徑輸入/輸出 （MPIO） 的最佳實務。使用這些設定修改許多 Linux 作業系統發行版本產生的「/etc/multipath.conf」檔案。

 

請參閱 Linux 文件，因為某些 Linux 作業系統發行版本可能需要自訂設定，以便在檔案投入使用前套用。

史：

  • PowerVault ME5 用字於 2022 年 4 月 25 日新增
  • 2020 年 2 月 11 日新增 PowerVault ME4 特定設定
  • MD34xx/38xx 特定設定
  • MD32xx/36xx 特定設定
  • 列入黑名單

 

您可以在名為「Dell EMC PowerVault ME4 系列與 Linux」 版本的文件 （2018 年 9 月） 中找到 ME4 設定預設值。

如需其他作業系統最佳實務，請參閱 Dell Technologies Infohub。

知識庫中有文字和檔案版本。文本在下面，檔已附加。

文字版本必須放入檔案中，或是 Linux 主機「multipath.conf」檔案中的取代文字。
