![]() If you go to the network adapter properties and click "configure" and then the "power management" tab you can adjust For this to work WOL needs to be enabled in the machine BIOS and in the OS. SCCM uses whats called a "Magic Packet" to wake the workstation. I've been trying to go "Green" at our company but I'm finding more and more that WOL is kind of a nightmare. I would look at the workstations and make sure that WOL is working. If not, you're going to have provide more details about what the actual problem is and what troubleshooting steps you have taken thus far. ![]() Hopefully the answer to your question is somewhere in here. Maybe you thought that enabling WOL cause your problem when really By setting this condition SCCM will skip this step if the computer is booted off the network. This variable is set to true when the machine is booted off the network and WinPE is loaded. Task Sequence Variable _SMSTSINWinPE equals "false" This group/step will be run if the following conditions are met: On the optios tab of each of those steps I have configured a condition. Neither of these steps can be performed once the computer is booted into WinPE. I have an "install software" step which runs an executable to modify the BIOS so that the computer attempts a network boot on the next restartĪnd I have the "restart computer" step. If you are manually booting into PXE and you are using the same task sequence that you are using for triggering a deployment on an existing client you will need to set up the initial steps so that they are skipped if the machine is already PXE-booted.įor example in one of my task sequences I have two steps that occur before the machine network boots to WinPE. Have your Task sequence set up properly to skip any steps that the OS would normally perform (such as restart into PXE),that the advertisement is properly configured and assigned to a collection that contains your imported computers with the correct MAC addresses,Īnd your machine is not stuck in the WDS cache (restart WDS to clear the cache or change the flush interval in the registry), yes it should work. Support the Intel-VPRO technology you can use this functionality to reset the power on a machine that is waiting for bootable media or to power on a machine that is turned off so that it can network boot and recieve it's PXE advertisement. You can perform a Bare Metal OSD with WOL enabled in the advertisement but the magic packet will have no effect on a machine that is not sleeping. powered off does not count as asleep either. Prompting for bootable media, it is not asleep. I have never seen a machine that has firmware suspend modes. Sleep or suspend modes (S1,S3,S4 etc) are triggered by the OS. Hope this gives you the info you need to have your machines wake up from suspend.Someone correct me if I'm wrong but if the machines have no OS installed, then they can not sleep. Unfortunately this command will need to be run every time your system boots, so be sure to add it to an appropriate startup script, such as part of the up rules in /etc/network/interfaces. You can choose other wake options as well, which are documented in the link above. s means "set", is the network interface, wol is "Wake on LAN", and g is "MagicPacket". If this is the case, you can enable it with this command: ethtool -s wol g ![]() If the value is d, this means the Wake-on value is disabled. A complete list can be found in the documentation (search for the string Wake-on-LAN options). There are several different options that the machine might be listening for. If it does, this means to wake the machine, it needs to receive a "MagicPacket" rather than something else. Supported link modes: 10baseT/Half 10baseT/FullĪdvertised link modes: 10baseT/Half 10baseT/FullĬheck the value of Wake-on contains a letter that is not d. The output should look something like this: Settings for enp0s31f6: If you’re not sure what the name is, sudo ip link show will provide the interface name. Note: Be sure to replace with the name of your device. That said, it can be quite bothersome for people who want their servers to wake and return to operation.įirst, let’s confirm that the driver used for the network card supports WoL. The Wake-on-LAN feature is a hardware setting rather than something the OS controls, so it technically makes sense that the machine remains suspended when receiving the magic packet.
