You create the state migration point role, in Microsoft System Center Configuration Manager 2007, by creating an instance of SMS_SCI_SysResUse Server WMI Class and providing the property values in the following table.

Property	Description
RoleName	Name of the role. For a state migration point, the value is SMS State Migration Point.
SiteCode	The site code for the site.
NALPath	The network abstraction layer (NAL) path to the state migration point. For more information, see PackNALPath Method in Class SMS_NAL_Methods.
NALType	The resource type. For a state migration point, this should be Windows NT Server.

You will also need to set initial values for the following embedded properties and embedded property lists.

Name	Description
Server Remote Name	The server that has the state migration point. Embedded property.
SMPQuiesceState	Sets the restore-only mode. For more information, see How to Set the Restore-Only Mode for a State Migration Point. Embedded property.
SMPStoreDeletionDelayTimeInMinutes	Sets the deletion policy. For more information, see How to Set the Deletion Policy for a State Migration Point. Embedded property.
SMPStoreDeletionCycleTimeInMinutes	Sets the deletion policy. For more information, see How to Set the Deletion Policy for a State Migration Point.
Directories	Lists the state migration point folders. For more information, see How to Add a State Migration Point Folder.

To create a state migration point role

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Create an instance of SMS_SCI_SysResUse Server WMI Class.
Populate the properties listed above.
Commit the SMS_SCI_SystResUse object.

Example

The following example method creates a state migration point from the supplied site code and NAL path. Some helper functions are provided for writing the embedded properties and embedded property lists to the site control file. The example also makes use of the other state migration point code snippets to set various role values.

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

public void CreateSmpRole(
     WqlConnectionManager connection,
     string serverName,
     string siteCode,
     string nalPath)
{
    try
    {
        // Create the state migration point resource object.
        IResultObject smpRole = connection.CreateInstance("SMS_SCI_SysResUse");
        smpRole["RoleName"].StringValue = "SMS State Migration Point";

        // Set the state migration point properties.
        smpRole["SiteCode"].StringValue = siteCode;
        smpRole["NALPath"].StringValue = nalPath;
        smpRole["NALType"].StringValue = "Windows NT Server";

        // Create the embedded property and property lists.
        this.WriteScfEmbeddedProperty(smpRole, "Server Remote Name", 0, serverName, string.Empty);
        this.WriteScfEmbeddedProperty(smpRole, "SMPQuiesceState", 1, string.Empty, string.Empty);
        this.WriteScfEmbeddedProperty(smpRole, "SMPStoreDeletionDelayTimeInMinutes", 0, string.Empty, string.Empty);
        this.WriteScfEmbeddedProperty(smpRole, "SMPStoreDeletionCycleTimeInMinutes", 0, string.Empty, string.Empty);
        this.WriteScfEmbeddedPropertyList(smpRole, "Directories", null);

        // Commit the site role.
        smpRole.Put();

        // Use SDK snippets to populate some values.
        this.AddSmpFolder(connection, @"C:\temp", 100, 10, 1, serverName, siteCode);
        this.SetRestoreOnlyMode(connection, serverName, siteCode, true);
        this.SetDeletionPolicy(connection, serverName, siteCode, 10);
    }
    catch (SmsException e)
    {
        Console.WriteLine("Failed to create the state migration point: " + e.Message);
        throw;
    }
}
public void WriteScfEmbeddedPropertyList(
    IResultObject resource,
    string propertyListName,
    string[] values
    )

    // Create an embedded property list for the supplied resource.
{
    Dictionary<string, IResultObject> EmbeddedPropertyList = resource.EmbeddedPropertyLists;

    // Get the property list, or create it. 
    IResultObject ropl;
    if (EmbeddedPropertyList.ContainsKey(propertyListName))
    {
        ropl = EmbeddedPropertyList[propertyListName];
    }
    else
    {
        ConnectionManagerBase connection = resource.ConnectionManager;
        ropl = connection.CreateEmbeddedObjectInstance("SMS_EmbeddedPropertyList");
        EmbeddedPropertyList.Add(propertyListName, ropl);
    }

    // Set the property list properties.
    ropl["PropertyListName"].StringValue = propertyListName;
    ropl["Values"].StringArrayValue = values;
    resource.EmbeddedPropertyLists = EmbeddedPropertyList;
}

public void WriteScfEmbeddedProperty(
    IResultObject resource,
    string propertyName,
    int value,
    string value1,
    string value2)
{
    // Properties
    // Server remote name
    Dictionary<string, IResultObject> EmbeddedProperties = resource.EmbeddedProperties;

    // Get the property, or create it.
    IResultObject ro;
    if (EmbeddedProperties.ContainsKey(propertyName))
    {
        ro = EmbeddedProperties[propertyName];
    }
    else
    {
        ConnectionManagerBase connection = resource.ConnectionManager;
        ro = connection.CreateEmbeddedObjectInstance("SMS_EmbeddedProperty");
        EmbeddedProperties.Add(propertyName, ro);
    }

    ro["PropertyName"].StringValue = propertyName;
    ro["Value"].IntegerValue = value;
    ro["Value1"].StringValue = value1;
    ro["Value2"].StringValue = value2;

    resource.EmbeddedProperties = EmbeddedProperties;
}

The example method has the following parameters:

Parameter	Type	Description
connection	Managed: WqlConnectionManager	A valid connection to the SMS Provider.
serverName	Managed: String	The Configuration Manager server that the state migration point is running on.
siteCode	Managed: String	The Configuration Manager site code.
nalPath	Managed: String	The NAL path to the state migration point. For example, `["Display=\\SERVERNAME\"]MSWNET:["SMS_SITE=SITECODE"]\\SERVERNAME\`
