Figure 25. Coexistence
The dependent node is only supported in PSSP 2.3 and higher PSSP versions. To use it with nodes with PSSP versions less than 2.3 requires the use of coexistence. The following conditions are required for the dependent node to communicate with nodes with a lower version than 2.3 using coexistence:
•The Control Workstation must be at PSSP 2.3 or higher to manage dependent nodes.
•The Primary node of the SP Switch must be at PSSP 2.3 or higher, as the Primary node needs to perform some tasks for the dependent node and these functions are only available in PSSP 2.3 and higher PSSP versions.
•The Primary Backup node of the SP Switch should be PSSP 2.3 or higher so that if the Primary node fails, the dependent node can continue to function in the RS/6000 SP when the Backup node takes over.
