• Critical — A significant event that indicates actual or imminent loss of data or loss of function, such as
crossing a failure threshold or a hardware failure.
SNMP Trap Based Severity Propagation
The following table describes the severity propagation for the Nodes hierarchy based on SNMP traps.
Table 7. SNMP Trap Based Severity Propagation
View Description
Nodes hierarchy The node status displays the highest severity of all
the active messages. This status is propagated to
the parent node groups. To know the actual health
of the node, view the status in the Global System
Status for the node under the Services hierarchy.
Auto Acknowledged Traps
These trap policies intercept and process the SNMP traps generated by the respective Dell device and
display the corresponding alert messages on the HPOM console. This policy has the trap-correlation
feature enabled and is auto-deployed when you are installing the Dell SPI.
For every trap received from the Dell device, the Dell SPI processes the traps in the following manner:
1. Sends a message to the active message browser of the node on the HPOM console.
2. For all Normal traps, the policy auto-acknowledges the messages and moves them from the active
message browser to the acknowledged message browser.
3. For all Critical and Warning traps, it retains the messages in the active message browser and auto
correlates the trap once it receives a corresponding Critical, Warning, or Normal trap.
4. Retrieves the global system status of the node and sends a message with the global system status to
the active message browser of the node.
If a node is not DNS resolvable, the Dell SPI may not update the global health status for that node.
NOTE: Auto correlation is not supported for the following Dell Devices:
• Dell Remote Access Controller (RAC)
• Dell Remote Access Controller/Modular Chassis (DRAC/MC)
• Dell Chassis Management Controller (CMC)
• Dell EqualLogic Storage Arrays
• Dell PowerVault MD Storage Arrays
• Dell Enterprise Switches (S-Series, M-Series and Z-Series)
All Normal, Warning, and Critical traps are retained in the active message browser.
Manually Acknowledged Traps
These trap policies intercept and process the SNMP traps generated by the respective Dell device and
display the corresponding alert messages on the HPOM console. The manually acknowledged traps have
to be manually deployed after installing the Dell SPI and does not automatically acknowledge the
received traps.
For every trap received from the Dell device, it processes the traps in the following manner:
1. Sends a message to the active message browser of the node on the HPOM console.
