HP OneView for Microsoft System Center - Manual (Page 28)

NOTE: If the snmpd.conf file is changed, you must restart the following services:
•
snmpd
•
hp-snmp-agents
On Linux/VMware servers, test SNMP traps can be generated from the same SNMP Settings
screen. Click Send Test Alert to send a test trap. If the management pack is functioning properly,
a test SNMP trap posts in the HP Device Monitor Log (in the NT Event log), and an alert is generated
on the SCOM console.
To view and update the SNMP Settings of an Agentless server:
1.
Log in to the server's iLO using a root privileged user.
2. Expand the Administration tab on the left.
3. Select the Management tab.
4. Verify that the iLO SNMP Alerts setting is enabled.
5. Verify that the IP address of the system (where the DMS is running) is registered as an alert
destination with a corresponding trap community string.
On Agentless systems, test SNMP traps can be generated from the same SNMP Settings screen.
Click Send Test Alert to send a test trap. If the management pack is functioning properly, a test
SNMP trap posts in the HP Device Monitor Log (in the NT Event log), and an alert is generated on
the SCOM console.
The DMC is unable to connect to the DMS
The DMC displays an error message indicating that it failed to connect to the DMS. To verify that
the DMC can connect to the DMS through the network:
1.
Verify that both the DMC and DMS systems have network connectivity.
2. Select Computer Management
→Services from the DMS.
3. Start the following services, if necessary:
•
HP Device Monitor Service
•
HP Common Services
Before starting HP Common Service, its dependent services, like the postGreSQL and Mosquitto
services needs to be checked. If they are stopped, then both services need to be started.
4. Verify that the HP Device Monitor Event log does not contain any error messages for the DMS.
The DMC is unable to connect to the DMS because of user credentials
The DMC uses the current user's credentials to access DMS. Verify that the current user has been
granted access to the local or remote system hosting DMS. You must have Administrator rights to
run the DMC unless an non-administrator account has been created. For more information, see
“Setting up a non-administrator account to use the DMC” (page 14) .
The DMC status line displays failure status
The DMC is configured to periodically connect with the DMS to update its data. The DMC displays
a failure status when it fails to connect with the DMS. Ensure that the network connection is working
and that the DMS is running.
A Linux or VMware ESX server is not displayed in the SCOM console after adding
a device with the same host name
If a Linux or VMware ESX server is added that has the same host name as an existing server device,
the server is added in the DMC, but the existing Linux or VMware ESX server is no longer displayed
in the SCOM console. To avoid this situation, do not assign the same host name to multiple devices.
