Dell EMC PowerPath for Linux 7.4 及次要版本安装和管理指南

安装签名的 PowerPath rpm 软件包

使用以下步骤在 Oracle Linux 7.x/8.x UEKR6、UEKR6 U1、UEKR6 U2 上安装签名的 PowerPath rpm 软件包。

1. 在主机上安装签名的 PowerPath rpm 软件包。
2. 启动 PowerPath 服务。签名的 PowerPath 模块应该已在启用安全启动的主机上成功加载。
3. 对所有六个单独的 PowerPath 模块 (.ko) 运行 modinfo 命令。emcp 模块的样例输出如下所示：
