Rapid activation of service management processor subsystem for server device
Abstract:
A bootloader process executing on a service management processor (SMP) subsystem for a server device determines whether flag stored within non-volatile memory of the subsystem is set. The flag corresponds to whether a full cold initialization process of the subsystem is to occur. In response to determining that the flag has not been set, the bootloader process loads an image stored in the non-volatile memory into volatile memory of the subsystem. The image corresponds to processes properly running on the SMP subsystem after the SMP subsystem has booted, including a management process. The processes begin executing on the subsystem. The management process, determines whether a hardware configuration change within the subsystem has been made since when the image was saved to the non-volatile memory. In response to determining that the hardware configuration change has been made, the management process sets the flag and rebooting the subsystem.
