重新启动 openibd (Infiniband) 服务时以太网连接断开

Question

我有多台服务器，服务器上装有以太网控制器，并且在 PCI 插槽中安装了 InfiniBand 控制器。

问题是，当我重新启动 openibd.service（它应该只控制 infiniband 适配器）时，由于某种原因，我的以太网网络也重新启动了。

如果我停止 openibd，我的以太网也会停止。

以太网和 InfiniBand 应该彼此分离和独立。

我需要能够在不断开以太网连接的情况下停止或重新启动 openibd.service

操作系统：AlmaLinux 8.7

正在使用的以太网端口（1gb）：eno2np1

Ofed 版本：MLNX_OFED_LINUX-5.9-0.5.6.0

重新启动 openibd.service 时，以太网连接断开，直到 openibd 再次运行。
我怀疑两张卡都使用相同的驱动程序，但我不确定如何继续。

所有卡上的固件均已更新。

我到目前为止尝试过

安装干净的操作系统
更新服务器的 UEFI 固件
更新 Mellanox 固件和 ofed\

Answer 1

作为openibd.service重启过程的一部分，脚本将卸载并重新加载mlx5_core模块，该模块作为 Mellanox / NVIDIA InfiniBand 和以太网卡（包括问题中列出的两张卡）的 PCIe 设备驱动程序。
