I am currently running LMS3.01 with DFM 3.03 and all my devices are in Questioned State. The DFM is no longer sending Alerts and Alarms to Notification groups. I checked the Notification Groups and there were no devices in Devices Selector. My support maintenance is yet to be signed so I can't call TAC. Your help will be appreciated

Hi Friend,

if you are using Windows have a look if .NET 2.0 SP1 is installed. If yes removed it and restart the server.

If this does not match have a try with the reset of the database passwords of DFM:

First you have to stop the processes

net stop crmdmgtd

cd to ..\CSCOpx\bin

Then issue the following cmd:

.\perl dsn=dfmEpm npwd=

.\perl dsn=dfmInv npwd=

.\perl dsn=dfmFh npwd=

Hope that helps a bit.

Best regards,

If you go to DFM > Device Management > Rediscover/Delete, what is the reason the devices are in a Questioned state?

SNMP Timeout is pretty self-explanatory. Make sure the SNMP credentials in DCR are correct for these devices, and increase DFM's SNMP timeout under DFM > Device Management > SNMP Config if necessary.

If you click on one of the devices under Others, what is the underlying reason it is Questioned?
