Alert monitor for Lenovo BladeCenter MM external network connection lost
Knowledge Base article:
Summary
This monitor watches for a BladeCenter event that indicates that
an advanced management module (AMM) link to the external network has been lost.
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.
The BladeCenter event is delivered to this monitor asynchronously.
There is no monitoring interval to configure for this monitor.
The BladeCenter event is delivered to this monitor from the AMM (Advanced
Management Module) of the BladeCenter via the SNMP (Simple Network Management
Protocol) protocol. It also goes through the BladeCenter runtime support
of the Hardware Management Pack installed on the management server that
was designated to manage the BladeCenter during the Network Device Discovery process.
For the proper BladeCenter AMM SNMP settings that are required for
the Hardware Management Pack to discover BladeCenter modules
and report events, consult the Hardware Management Pack's User's Guide.
Causes
When the AMM link to the external network has been lost, the BladeCenter's AMM generates a hardware event.
The health state of this monitor is then set to the Critical or Warning state.
