The server has a pair of redundant SPs labeled SP0 and SP1. One SP functions as the Active SP to manage the server, while the other acts as a Standby SP that assumes the Active SP role in the event of a failure.
When you power on the server, the boot process begins under the control of the Oracle ILOM system console. The system console displays status and error messages generated by firmware-based tests that run during the system startup.
After the system console finishes its low-level system diagnostics, the Active SP initializes and runs a suite of higher level diagnostics. When you access the SP using a terminal device connected to the Active SP SER MGT 0 port, you see the diagnostic and startup messages.
For a detailed discussion on configuring the system console, refer to the SPARC M8 and SPARC M7 Servers Administration Guide and the Oracle ILOM documentation.
