提醒：以下命令应该是 Linux作系统的本机命令，可以从任何位置运行。命令区分大小写。您可能必须按照”> filename.txt" 将文本输出到文件以供审阅。例如： lspci > filename.txt
- 首先，让我们通过运行以下命令来确定相关设备的总线地址：
lspci
- 我们可以看到一个 LSI RAID 控制器，但该控制器不是 RAID 控制器，因此这是不正确的设备。唯一的其他 LSI 设备被列为具有总线地址”
04:00.0”提醒：我们还可以看到列出了其他设备，例如 Intel 82599EB 10 GB NIC。您可以使用其 LUN ID 查看此双端口 NIC 上的两个端口.0或.1 - 此时，我们有两个选项：
运行命令lspci -nv并在其中搜索我们的公交车地址，在本例中为”04:00.0”
提醒：我们可以看到”LnkCap“替换为”Width x8“和”LnkSta“替换为”Width x8“由此我们可以看到，该设备的协商速度为 8 倍。 - 或者我们可以运行命令
dmidecode并在其中搜索我们的公交车地址，在本例中为”04:00.0”
提醒：我们可以在“Designation”下看到插槽类型接受x16,x8, or x4。从“Type”中，我们可以看到插槽的长度为x16。
