Working with LCS devices

Working with LCS devices includes tasks such as creating an LCS group device, specifying a timeout, or activating an interface.

Most of these tasks involve writing to and reading from device attributes in sysfs. Using attributes is useful on a running system where you want to make dynamic changes. If you want to make persistent changes across IPLs, use the interface configuration files. Network configuration parameters are defined in /etc/sysconfig/network-scripts/ifcfg-<if_name>. See the Red Hat documentation website for an example of how to define an LCS device persistently. The website also contains a general discussion of network configuration files, see
