简介
本文档介绍如何对视频通信服务器(VCS)上的以太网端口、风扇和磁盘故障进行故障排除。
硬件故障
以太网端口故障
VCS硬件上有四个以太网端口。以root用户身份登录并输入ifconfig -a命令。应显示所有四个端口。

如果未显示全部四个端口，则VCS出现问题，需要更换为网络接口控制器(NIC)发生故障。
VCS虚拟机(VM)有三个NIC端口，而不是四个。因此，当您对VCS VM上的NIC故障进行故障排除时，ifconfig -a命令应显示三个以太网端口。以root用户身份登录并输入ifconfig -a命令。
~ # ifconfig -a

风扇故障
如果两个或多个风扇发生故障，VCS版本7会报告风扇故障。但是，VCS仍然可以正常运行。如果VCS上的温度太高，可以处理RMA。
VCS有五个风扇，但是每次只报告三个风扇的状态。一个风扇故障实际上可能也是三个故障风扇。
以root用户身份登录并输入sensors命令以检查VCS上的温度。

只要温度看起来不错，您就无需RMA VCS。
磁盘故障
VCS上有两种类型的磁盘：
- SDA — 这是VCS上的主磁盘。此磁盘故障导致VCS完全无法启动。如果此操作失败，VCS将根本不加载映像。
- SDB — 这是辅助磁盘。此磁盘故障可能会导致VCS上的问题。
以root身份登录并输入smartctl命令，以确定测试是否通过（SDB正常）。PASSED以外的结果不正确。
