Alerts when Lenovo System memory addition or removal
Knowledge Base article:
Summary
This monitor reports hardware problems of a physical memory unit that occurred when it was removed from a server.
Configuration
You can disable this monitor through the Operations Manager's Operations
Console. See the "Disable monitors" topic in the Operations Manager's
Operations User's Guide for more information.
Hardware-platform-specific events, such as this one, are delivered asynchronously
to this monitor. There is no monitoring interval to configure for this monitor.
The hardware event with this monitor is available only on an Lenovo system
with the appropriate hardware sensors and with a management controller
(also called a Service Processor), such as Integrated Management Module
(IMM), Baseboard Management Controller (BMC), Remote Supervisor Adapter
(RSA), or an equivalent management controller on an older Lenovo system.
This monitor depends on hardware instrumentation software, namely the
IBM Director Platform Agent (also called Core Services) and the Intelligent
Platform Management Interface (IPMI) driver stack. This software raises
the hardware event to the WMI level, so that the monitor can be notified.
On certain configurations, the RSA daemon can be used in place of, or
in parallel with, the IPMI driver stack. See the "Additional Information"
section below for more information about Lenovo Director Platform Agent,
the IPMI driver stack and the RSA daemon.
Causes
When a physical memory unit is removed from a server, a hardware event is generated. The health state of this monitor is then set to the Critical or Warning state.
For a particular incident, review the history in the State Changes tab. Consult the relevant hardware
knowledge articles listed below, keeping in mind the relevant event data.
The relevant Lenovo hardware knowledge articles are available on a system with the Lenovo Hardware Management Pack
package installed.
A physical memory unit was removed
Resolutions
Review the relevant Lenovo hardware knowledge articles listed above for information about how to resolve the
hardware problem for a particular incident.
The monitor generates an alert when its health state changes to either Critical or Warning.
After the physical memory is running again normally,
the health state will be automatically restored to the Healthy state. Any outstanding corresponding alerts will
also be automatically closed.
