8.5.3 How to Change the Configuration of a TC

Run the scconf -t command on all cluster nodes to change the configuration of a particular TC in the system. For example, to change a TC IP address, use the following command, in which -i specifies a new IP address (129.34.123.52) for the specified Terminal Concentrator (or SSP), and -l specifies a new port (8) used for locking purposes in failure fencing:

# scconf clustername -t foo-tc -i 129.34.123.52 -l -8

If a Terminal Concentrator is being used, an unused TC port from 2 to n is specified, where n is the number of ports in the TC. If a SSP is being used, a value of -1 must be specified.
