IMC 7.2 fails to connect to SCVMM server with Powershell "Server busy"

kortemi — Thu, 25 Feb 2016 10:28:50 GMT

Hi,

I'm trying to bring VRM into IMC, but failing miserably so far.

We use SCVMM (4 hosts in a cluster, 1 standalone host) for VM management, and I am trying to follow instructions laid out in documentation. According to the documentation, if you have SCVMM, you need to connect with Powershell.

I've created a Powershell Access Parameter Template,, with the correct user name, password and port 8100, and when I select "Test connection to vManager/physical server" and select our SCVMM server, I keep getting the "Server busy, please try again later" message.

I've followed all troubleshooting tips I've managed to find: So far I've

Installed the VRM plugin on the SCVMM server and configured the imf.cfg file (IMGAddress=<IMC server IP>IMGPort=8800)
Installed the LLDP agent on the SCVMM server
set the PS ececutionpolicy on the SCVMM server to "ByPass"

Now when I edit the Powershell Parameter Template, and test it, I get the above mentioned error.
And if I change the user account info, I get an error "could not access", so I know that the user account information is correct.

The interesting thing is, on the SCVMM server (where I have the VRM plugin), the imcvnmagent<date>.txt log file seems to indicate that the VRM plugin is polling IP addresses at random for a VMM, which seems strange.

Here are some lines from the log, after I restarted the service:

Would anyone have any ideas why PowerShell is unable to connect?

Does noone else have this problem?

I hoped that updating to Patch 04 of IMC would help, but the situation remains the same, server busy....

Well, for anyone else out there that has been having this problem, I am happy to let you know that this has been solved.

And it was a bug in the IMC product: My target SCVMM server was running Windows Server 2012 R2, and apparently that was not supported (though this was NOT mentioned anywhere in the documentation, or online).

By upgrading to 7.2 E0304P06 the problem was solved, and the added support for Windows Server 2012 R2 was mentioned in the release notes.

So, if you are having the same problem, don't waste time trying to solve this until you've upgraded.
