7 Troubleshooting the HP Device Monitor
Introduction
The following information is designed to help resolve some common operating issues that might
occur when using the HP Device Monitor.
Device monitor management issues
This section provides troubleshooting information for device monitor management issues with the
HP Device Monitor and SCOM.
Same device added to more than one device monitor connection (DMS)
It is possible to add the same device to more than one device monitor connection. If a device is
added more than once, SCOM displays multiple instances of the device and duplicate alerts are
generated for each instance.
DMC operational and usage issues
This section provides troubleshooting information for operational and usage issues with the HP
Device Monitor and SCOM.
DMC connection to DMS service hangs after server power outage
If the HP Device Monitor Console (DMC) cannot connect with a local or remote HP Device Monitor
Service (DMS), it may be the result of a power failure or other unexpected shutdown event of the
system running the DMS.
When a server recovers back from a power outage, DMC should be able to connect to a local
DMS connection without any issues. However it has been noted that after the power connection
is restored, the DMC connection to the local host DMS service can hang for an indefinite amount
of time.
Suggested action
Restarting the target DMS should allow the DMC to successfully connect to the DMS. Run the
following commands to restart the service:
NET STOP HPDeviceMonitorService
NET START HPDeviceMonitorService
Unable to add OA through DMC
When encountering this issue, first verify that the OA is configured to allow the anonymous XML
response:
1. Login to OA.
2. Navigate to Enclosure Information | Enclosure Settings | Network Access.
3. Make sure Enable XML Reply is checked.
Another troubleshooting tip is to verify that Port 80 is not being blocked by the firewall.
Checking DMS operation
If a problem with the DMS has occurred, first perform the following steps:
1.
Launch the DMC to determine whether the DMS is working. If it is, you can log in and see the
list of managed devices.
2. Determine whether the DMS has reported an alert. View alerts by selecting the HP
Systems
→Active Alerts view in the SCOM console.
