Replacing a Failed Terminal Concentrator

The Terminal Concentrator need not be operational for the cluster to stay up. If the Terminal Concentrator fails, the cluster itself does not fail.

You can replace a failed Terminal Concentrator without affecting the cluster. If the new Terminal Concentrator has retained the same name, IP address, and password as the original, then no cluster commands are required. Simply plug in the new Terminal Concentrator and it will work as expected.

If the replacement Terminal Concentrator has a new name, IP address, or password, use the scconf(1M) command as described in "Changing TC/SSP Information", to change this information in the cluster database. This can be done with the cluster running without affecting cluster operations.
