Detailed Description

The Detailed Picture of Hardware Monitoring

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 57.

The startup process is managed by the startup client (startcfg_client). The startup client is run when the system is restarted, following an 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 an 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 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.
