目录 简介 硬件故障 以太网端口失败 风扇故障 磁盘故障 简介 本文描述如何排除故障以太网端口、风扇和磁盘故障视频通信服务器的(VC).

硬件故障 以太网端口失败 有VC硬件的四个以太网端口.登陆作为根并且输入ifconfig - a命令.应该显示全部四个端口. ~ # ifconfig -a eth0 Link encap:Ethernet HWaddr 00:10:F3:18:2F:AE inet addr:10.104.214.202 Bcast:10.104.214.255 Mask:255.255.255.192 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:7726332 errors:0 dropped:0 overruns:0 frame:0 TX packets:7436734 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1329156143 (1267.5 Mb) TX bytes:3590189626 (3423.8 Mb) Interrupt:18 Memory:fdae0000-fdb00000 eth1 Link encap:Ethernet HWaddr 00:10:F3:18:2F:AF inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:19 Memory:fd8e0000-fd900000 eth2 Link encap:Ethernet HWaddr 00:10:F3:18:2F:B0 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:16 Memory:fd6e0000-fd700000 eth3 Link encap:Ethernet HWaddr 00:10:F3:18:2F:B1 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:17 Memory:fd4e0000-fd500000 ip6tnl0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 NOARP MTU:1452 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:30151925 errors:0 dropped:0 overruns:0 frame:0 TX packets:30151925 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:30219125820 (28819.2 Mb) TX bytes:30219125820 (28819.2 Mb) sit0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) ~ # 如果全部四个端口没有显示,则有与VC的一问题,并且需要替换作为网络接口控制器(NIC)失败.
