Unable to Upgrade DCNM from 11.1.1.0 to 11.3.1

[DClements]

Hi, 

I am trying to upgrade DCNM from 11.1.1.0 to 11.3(1) on my windows 2016 server and after reading release notes for 11.3(1) it appears that I can do an in place upgrade, see below. After trying multiple times I an unable as the installer states the following ports are needed by DCNM are not free. DCNM services have been stop and confirmed stopped in services.msc but the installation still states that the ports are in use are a retry. Server has been rebooted. I am probably missing something simple so any help would be appreciated.

Hello sir,

I have had this issue before, there could be a number of reasons:

- Once you stop the DCNM service, the ports are still in used and the connections are not timed out and eliminated from the netstat table.

- You have the firewall on, and once you stop the services, the fw on Windows would not allow the ports(This may not make sense since DCNM was working).

- The services are not completely stop.

Recommendations:

- Restart the windows server with the stopped DCNM service, of this server only contains the DCNM. This will help us eliminate the active conns, and make sure the services are completely stopped.

- Turn off the FW and if possible the AV.

If you cant do any of the above, you could possibly create inbound and outbound FW rules to make sure those ports are allowed in the Windows FW:

and kill the remaining active connections through CMD, you need to run netstat to see what is still active using the ports you need:

It is usually better to come clean with restarting, and if it does not work then, proceed with the other solutions.
