Communicating With an SCP Process
To route commands to most subsystems, a management application must open an SCP
process. If no SCP process exists, the management application or an interactive user
must start one. The management application opens the SCP process, specifying that
messages are in SPI format. The management application and SCP process then
exchange SPI command and response messages using the Guardian WRITEREAD and
READUPDATE procedures. When the application finishes its management tasks, it can
stop the SCP process or close it without stopping it.
