Startup Process (in Detail)

The following steps describe the process used to start the hardware monitoring. The startup process is
illustrated in Figure 3-2 on page 65.
The startup process is managed by the startup client (startcfg_client). The startup client is run when the
system is restarted, following the execution of the IOSCAN utility (performing a real/hard ioscan), when the
enable monitoring command is executed from the Hardware Monitoring Request Manager, or when
monconfig changes the monitor requests.
1. When the system is restarted, following the execution of the IOSCAN utility (performing a real/hard
ioscan), or when the enable monitoring command is executed, the Hardware Monitoring Request
Manager (monconfig) calls the start up client (startcfg_client).
2. The startup client reads the contents of a monitor startup configuration file and registers the monitoring
requests contained in the file with the EMS registrar. This causes the associated monitor to start running.
If monitoring is already enabled, the startup client unregisters all current monitoring requests, then
reads the content of the startup configuration files and registers the requests again.
3. The monitor examines the IOSCAN (ioscan -k) results table to determine if there are any hardware
resources on the system that it is responsible for monitoring. If it finds such resources, the monitor
continues to run. If it does not find any resources, the monitor stops.
4. If the monitor supports asynchronous event detection, it registers with diaglogd, indicating what types
of errors the monitor wants to receive. The monitor may specify a product description, product number, or
driver name.
5. The startup client then repeats the process for all monitor startup configuration files.
