System Configuration LockDown Mode

‘System Configuration Lock Down Mode’ provide a configurable option to the customer so that after it is enabled, any configuration on that particular system is not permitted with some exceptions. Typical usage of this setting is after the system is provisioned to a certain level along with the rest of the systems in the domain, and then enabling this mode reduces the drift the systems usually see during the operation over a period of time.

When the server is in “System configuration lockdown” mode, you are not allowed to initiate any of the configuration operations from either OMSS GUI or CLI. If this mode is set, you are not allowed to perform most of the operations in OMSS except some of the enumeration or reporting operations.

You can enable the lockdown mode from the iDRAC GUI. For enabling the lockdown mode, you have to select the Turn on the System Lockdown mode option from the More Actions drop-down menu on the iDRAC page. It may take some time for the changes to be available on the OMSS GUI.

NOTE: OMSS does not support configuring or setting the lockdown mode from either GUI or CLI. For enabling the system configuration lockdown mode, you have to access iDRAC GUI or similar applications.
NOTE: If you restart the data manager/Engine service after setting the system lockdown mode on, then the immediate reflection on the OMSS page happens. You might have to refresh the OMSS GUI after the restart, if required.

OMSS CLI: Only the tasks available or supported in the GUI will be available or supported in the OMSS CLI, when the system is in “System configuration lockdown” mode. If you try to run any of the unsupported operations, the following error message is displayed.

‘Error! System Configuration Lockdown mode is turned ON. Configuration actions cannot be performed in this mode. Operation failed!!!’
