4.3.2 Using Terminal Concentrator and System Service Processor Monitoring

Sun Cluster 2.2 monitors the Terminal Concentrator (TC), or the System Service Processor (SSP) on E10000 machines, on clusters with greater than two nodes. You can use this feature if you are upgrading from Sun Cluster 2.0 to Sun Cluster 2.2. To enable it, you will need to provide the following information to the scinstall(1M) command during the upgrade procedure:

• TC or SSP name(s).

• IP addresses for the TC or SSP.

• The root password for the TC or the user ssp password for the SSP.

The TC and SSP passwords are required for failure fencing to work correctly in the cluster. Failure to correctly set the TC or SSP password might cause unpredictable results in the event of a node failure.

• The physical port numbers to which each server is connected. This is the port number to which the serial line is connected, not the telnet(1) port number used in the /etc/serialports file. For example, if /etc/serialports defines a port connection as 5006, the physical port number is 6.

• The server architecture type. For each cluster node this is either "E10000" or "other."
