I have been having series of error on my CiscoWorks Server. It all started when I noticed this error message DCR Server is down or inaccessible. With some information I got on this forum, I changed some services startup to Manual but I am still having errors as shown in the CS screenshot in the attachment.
I'll appreciate if I could be helped out and get the Server running very well.
You need to upgrade to DFM 3.0.4 or higher. To do this, you must first upgrade to LMS 3.0.1. Once you are on 3.0.1, you can upgrade to DFM 3.0.5 from Common Services > Software Center > Software Update. LMS 3.0.1 can be downloaded from http://www.cisco.com/cgi-bin/tablebuild.pl/lms301 .
I'll like to mention this which I have noticed in the last 3 days. In addition to the device discovery issue, I have to restart the HP server machine on which the CiscoWorks is installed in the morning before I can to access/login to CiscoWorks application. The operating system is Windows Server 2003.
Also, prior to the device discovery hanging at 10%, the devices were properly discovered with status KNOWN and alerts are being generated for devices. Could you please explain further the reason for the upgrade to DFM 3.0.4
There are two bugs in the version of DFM you have. One causes DFM to eat up all of the available network buffer space which can crash any network application on the server. The other bug is one where devices drop out of Known status. They go back into learning. If the first bug was fixed, they would then move to Questioned. But because of the first bug, they hang at 10%.
SNMP Timeout may mean just that. Use a sniffer to see if DFM is polling the devices with the correct SNMP credentials. If you are using SNMPv3, you may be seeing a deviec bug where the SNMP engine IDs are duplicated. This will cause DFM to poll with incorrect v3 attributes, and lead to a timeout problem.
A device stuck at 40% means DFM is trying to poll it, and manage it. Debugging this will involve running some CLI commands against the DFM servers. If you open a TAC service request, they can walk you through the required steps.
