U2000 Product (V1R6C02) reports the “error” The matching NE Explorer is not found”, when I create new Huawei OSN 3500

Issue Description

The U2000 shows the “error dialog” The matching NE Explorer is not found ”, when I create new Huawei OSN 3500 on the U2000.

Alarm Information

The matching NE Explorer is not found

Handling Process

1． First, checking the license information, to see whether it supports the operation of creating Huawei OSN 3500. I found that the license is no problem. The license information like the below page:

2.   Second, checking the background process of U2000

       1). I found that all the process we can found through U2000 System monitor is normal.

       2). Then, I telnet to the U2000 server and reboot the server process

                 The command like below:

                       Switch to the destination path: cd /opt/OSSENGR/engineering

                       Stop the server:  ./stopserver.sh

                       Start the server:  ./startserver.sh

                 Then I create the OSN 3500 again, but the problem still exist. The NE 

can’t be created.
        3). Lastly, I login in the U2000 NMS Maintenance
                     I compare the instance with my PC U2000 Server, I found that there is lack of NEMGR_SDH instance.
                   
So, I deploy the deployment package and add the NEMGR_SDH instance.
The problem is resolved; I can create the OSN 3500 normally.

Root Cause

1． Maybe the license was not support the NE.
2． Maybe the related background process of U2000 did not start.
3． Maybe the deployment packages were not deployed
