Users Guide

Dell Command | PowerShell Provider resources work seamlessly in both Push and Pull modes. In Push mode you author a configuration,
stage it to generate the Managed Object Format (MOF), and enact it on target nodes. In Push mode the server is only a medium to author
and enact the configuration onto nodes. The Local Configuration Manager (LCM) agent on the target nodes, ensures that systems are
configured according to the configuration declaration. In Pull mode, the server is defined as a Pull Server. The Pull Server has web services
running which initiates a handshake between the server and the client systems. The server contains the MOF at a standard location, and
whenever there is a change in the checksum associated with the MOF file, the client machine(s) pulls the configuration from the server
and enforces it on the client systems. In Pull mode the LCM of the client system(s) is set to Pull mode. These settings of the LCM are
called meta – configuration.
Desired State Configuration Logs can be viewed using Windows Event Viewer. Configuration drifts on Dell client systems are recorded
in this event log at Applications and Service Logs -> DellClientBIOS PowerShell.
