Nice to Know–Bare metal deployment in SCVMM using Custom script and Custom resources could fail

Posted by Mikael Nystrom on May 4, 2014

The bare metal OS deployment function in SCVMM has the ability to be customized by adding custom scripts (also know as GCE). Basically there is two ways to do this, you either make sure the  script is in the WinPE image or you add it using recourses in the SCVMM Library. There are two locations for those scripts, Pre and Post and the problem seems to be true when we are doing Pre OSD GCE’s. So how do I know it fails then?, well that is not that hard. It will give you a very informative message in the job log like this:

Error (2941)
VMM is unable to complete the request. The connection to the agent on machine SCVMM01.network.local has been lost.
Unknown error (0x80072efe)

Recommended Action
Ensure that the WS-Management service and the agent are installed and running and that a firewall is not blocking HTTPS traffic.

And if you open the vmmAgentPE.exe.log file on the host you are deploying you will se this:

058C.05C4::05/04-12:23:13.425#00:OSDDownloadFileFromUrl.cpp(88)[000000000306EB: ThrowOnWin32Failure : 80072efe. Operation attempted WinHttpReceiveResponse(m_hRequest, NULL)
058C.05C4::05/04-12:23:13.425#00:exceptions.cpp(97)[000000000306EB: CarmineException::CarmineException: CarmineError: 1051488,  hr: 0x80072efe

If you look at the last file it tries to download you will see that it is trying to download the SCVMMCRTag.cr file and if you check the size of the file you will se that the size is 0 bytes and “carmine” does not like to transfer 0 size files in WinPE.

Solution:

Modify the SCVMMCRTag.cr in notepad.exe and type whatever you like, close it, done. If you try once more it should work.
