54 MPCMM0001 Chassis Management Module Software Technical Product Specification
Process Monitoring and Integrity
6.7.12 Excessive Failover/Reboots, Administrative Action
Prior to executing any failover/reboot the PMS will determine if the failover/reboot threshold has
been exceeded. If it has, the PMS will be operationally disabled. When PMS is disabled, all process
monitoring is halted. To re-enable the PMS, the operator must lock the global administrative state.
The operator can then fix the problem and administratively unlock the global administrative state.
The following events are generated against the PMS Monitor (unique ID 1). The events for the
process or processes that caused this condition to occur will also be present, but are not described
in this table. They are defined in the scenarios provided above.
6.8 Process Integrity Executable (PIE)
The Process Integrity Executable (PIE) for the Chassis Management Module’s (CMM) Blade
Proxy Manager (BPM) and Wrapper Processes is responsible for determining the health of the
Wrapper Processes. Monitoring the integrity means not only monitoring the fact that the process is
running but that it is functioning properly.
The PIE will monitor the BPM, CMM Wrapper Process (Wrapper Process number 255) and
Chassis Wrapper Processes (23). It will also monitor the Wrapper Processes for intelligent (have a
management controller) blades, power supplies, and fans. Wrapper Processes for non-intelligent
devices will not be monitored.
PIE will monitor the BPM and Wrapper Processes. The Wrapper Processes have two categories for
integrity monitoring. The first category contains the static processes. Static processes are processes
that are always present while the CMM software is running. The CMM (255) and chassis (23)
Wrapper Processes are the static processes. The second category contains all the dynamic Wrapper
Processes. Dynamic processes are ones that come and go as the configuration of the chassis
changes (such as a blade insertion or removal). The fan, power supply, and blade Wrapper
Processes belong to the dynamic category.
