Issue Description
In many cases, need to enable the second network adapter under the sue Linux which is installed in T8000 blade and configure IP address, but using YAST cannot see the information of the second network adapter. Use command “ifup eth1”, it prompts there is no configuration file:
eth1      device: Broadcom Corporation NetXtreme BCM5715 Gigabit Ethernet (rev a3)
ERROR: No configuration found for eth1
Alarm Information
None.
Handling Process
1. Use “ifconfig -a” command check the name and MAC address of the network which needs to be enabled.

2. Check whether there is the configuration file which is named by this MAC address in “/etc/sysconfig/network” directory. 

If there is no this document, need to create a new file, according to the above naming way name.
3. Then use vi edit this file, modify the inside IP address, mask, radio address and then save them.
