CHAPTER 1 Watchdog Timer The system management controller (SMC) on the Netra CP2500 implements a watchdog service that captures catastrophic faults in the Solaris OS running on the CPU board. The watchdog service reports such faults to the baseboard management controller (BMC) by means of either an IPMI message or by a de-assertion of the CPU’s HEALTHY# signal. This chapter contains the following sections: ■ “Overview” on page 1 ■ “PICL Plug-In Module” on page 2 ■ “Watchdog Node Management Code”

PICL Plug-In Module The watchdog subsystem is managed by a platform information and control library (PICL) plug-in module. This PICL plug-in module provides a set of PICL properties to the system, which enables a Solaris PICL client to specify the attributes of the watchdog system. To use the PICL API to set the watchdog properties, your application must follow the following sequence: Note – The following instructions are not server-specific. Check your server documentation for additional softwa
