In Microsoft System Center Configuration Manager 2007, you add an operating system deployment state migration point folder by adding the folder description to the Directories embedded property list.

The folder description is a string that defines the following information.

Value Description

Directory

The name of the folder.

MaxClients

The maximum number of clients supported.

MinDiskSpace

The minimum disk space required.

MinDiskSpaceUnit

The minimum disk space units.

1 - MB

2 - GB

3 - Percentage

To add a state migration point folder

  1. Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.

  2. Make a connection to the state migration point resources section of the site control file.

  3. Get the Directories embedded properties list.

  4. Update the Directories embedded property with new folder.

  5. Commit the changes to the site control file.

Example

The following example method adds a new folder to the state migration point.

For information about calling the sample code, see Calling Configuration Manager Code Snippets.

	Set InParams = connection.Get("SMS_SiteControlFile").Methods_("CommitSCF").InParameters.SpawnInstance_
	InParams.SiteCode = siteCode
   connection.ExecMethod "SMS_SiteControlFile", "CommitSCF", InParams, , context

 End Sub
C#  Copy Code
public void AddSmpFolder(
	WqlConnectionManager connection,
	string directory,
	int maxClients,
	int minDiskSpace,
	int minDiskSpaceUnit,
	string serverName,

	try

		string smpSettings = "Directory=" + 
			directory +

		// Get state migration point properties from site control file.
		IResultObject ro = connection.GetInstance(
			"SMS_SCI_SysResUse.FileType=2,ItemName='[\"Display=\\\\" +

			siteCode + "\"]\\\\" +

			siteCode + 
			"'"
			);

		// Get directories.
		Dictionary<string, IResultObject> embeddedPropertyLists = ro.EmbeddedPropertyLists;

		string[] directories = embeddedPropertyLists["Directories"]["Values"].StringArrayValue; // Current directories.

		List<string> directoriesList = new List<string>(); // convert to list.
		foreach (string directoryName in directories)
		{
			directoriesList.Add(directoryName);
	}

		directoriesList.Add(smpSettings);

		// Update the embedded property list.
		embeddedPropertyLists["Directories"]["Values"].StringArrayValue = directoriesList.ToArray();

		ro.EmbeddedPropertyLists = embeddedPropertyLists;

		// Commit changes.
		ro.Put();
}
	catch (SmsException e)
	{
		Console.WriteLine("failed to update SMP settings" + e.Message);
		throw;
}
}
