By using this menu, an HMC can be configured to report to another HMC.
When you
change the Service Agent mode, the actual call home is performed through
the second
HMC. This way, only one modem is needed for a group of HMCs. Service
Agent refers
to the HMC with a modem as a gateway and the ones reporting errors
as Service Agent
clients.
For more information about changing the Service Agent Configuration, see the Electronic Service Agent for pSeries Hardware Management Console User's Guide.
