Inventorying Wake-On-Lan Configuration for Dell Workstations using ConfigMgr and OMCI

This is a step-by-step example of using OMCI with ConfigMgr. This example will use the tools found on the Using OMCI with ConfigMgr page. As with all ConfigMgr Changes - TEST FIRST!
 

Scenario - You want to use ConfigMgr to identify systems where the BIOS is not configured with Wake-On-LAN (WOL) enabled.

Configure Inventory:

1. If you do not have OMCI installed, Install OMCI on all workstation systems. This will populate the root\dellomci namespace with hardware-specific information from the system. You can use traditional software distribution, or a Custom Updates deployment if you prefer.
2. Review the OMCI Reference Guide - In this example, search the page for "Wake" - notice there is a property named WakeupOnLAN (See Table 1). This Property will tell us if WOL is enabled.Notice that the WakeupOnLAN property is in the Dell_SMBIOSSettings Class
3. Review the OMCI/SCCM Whitepaper - You can search the paper for Dell_SMBIOSSettings Class, but due to word-wrap and other formatting requirements for the whitepaper, a straight copy-paste may not be easy to reproduce. For consistent formatting, download or open the Dell OMCI MOF Extensions for ConfigMgr link, which contains ALL Dell OMCI Reporting classes in MOF format. Copy the section for Dell_SMBIOSSettings, as shown in Table 2.
4. On the ConfigMgr Central site navigate to %installdir%\Inboxes\clifiles.src\hinv, where %installdir% is the installation directory for ConfigMgr.
5. Make a backup copy of SMS_DEF.MOF.
6. Use Notepad to edit SMS_DEF.MOF. Review SMS_DEF.MOF to ensure that the Dell_SMBIOSSettings class does not already exist in the MOF file.
7. Move to the end of the SMS_DEF.MOF File, and create a commented separator, so that you can easily identify additional reporting classes that you have added to the SMS_DEF.MOF. For example, create a separator similar to Table 3.
8. Paste the reporting Class Information for Dell_SMBIOSSettings into the SMS_DEF.MOF.
9. Enable the reporting class by setting the Report to TRUE, as shown in the first line of Table 2.
10. Enable the properties to report by changing FALSE to TRUE on individual properties, as shown in Table 2 for WakeupOnLAN. Modify reporting for other properties as desired.
11. Save SMS_DEF.MOF. Within a few minutes, ConfigMgr will detect the change in the SMS_DEF.MOF file, and automatically recompile it. View the SMS_INVENTORY_DATA_LOADER component status to verify success.
12. Clients assigned to this site will report the updated inventory at the next scheduled hardware inventory cycle (default is every 7 days).

*NOTE: As with all SMS_DEF.MOF changes, if you have multiple sites you must edit the SMS_DEF.MOF on all sites to obtain accurate reporting data. A best practice is to ensure all sites have the same SMS_DEF.MOF if possible.

Configure Reporting:

Now that you have the data in ConfigMgr, simply create a new web report, using the SQL statement in Table 4. You can also download a MOF file for a web report titled Wake On LAN Hardware Configuration.
