Router Node 61
PSSP 2.4 to represent coexistence. Also, note that Node 16 is empty,
because the SP Switch port for this node is used by the SP Switch router
adapter in the GRF.
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.
