SNMP Traps Received At Wrong Nodes Due To Error In

DNS Cache

Problem

After you start monitoring the Dell systems grouped under Dell Managed Systems group, if you

interchange the IP addresses of the nodes, then the SNMP traps are received on the wrong nodes. For

example, if you have two nodes A and B under Dell Managed Systems → Dell Monolithic Servers group

and you interchange the IP addresses of the two nodes, then the traps from A are displayed as messages

in the active message browser of B and vice versa.

Solution

To resolve this:

1. Launch the Server Configuration Editor on the HP Operations Manager (HPOM) console.

2. Under the Node Cache Settings option, set the DNS cache value to False to disable the DNS

caching. The nodes now display the traps correctly.

Global System Status Not Retrieved For Dell Devices

Problem

The Dell Server Scheduled Status Poll policy does not retrieve the global system status of the classified

Dell devices until the devices are grouped under the Dell Managed Systems group.

Solution

The global status update policy is scheduled to run at 02:00 hours every day and starts polling systems

for global system status. If you choose to auto-deploy the policy files during the Dell SPI installation, the

policies start running as per the default schedule. However, the auto grouping policy is scheduled to run

only at 04:00 hours every week. Therefore, until the Dell Hardware Autogroup Policy runs and the Dell

devices are grouped under the Dell Managed Systems group, the global system status of the devices are

not displayed on the HPOM console.

Trap Correlation Feature Is Not Working After The Dell

SPI Repair Operation

Problem

After the repair operation, correlation of traps do not occur for some groups of Dell devices.

Reason

The Dell SPI does not identify and disable the policies that have been manually deployed on the

management server prior to using the repair feature. After using the repair feature of the Dell SPI, the

default policies are deployed along with the previously deployed Manual Ack policies, if any. For more

information about Dell SPI default and Manual Ack policies, see Deploying Smart Plug-in Policies.

Solution

It is recommended to either have correlation policies or Manual Ack policies enabled for the Dell devices

you want to monitor at any given time. To have trap correlation feature for a Dell device, disable the

device specific Manual Ack policy.
