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.
When the server is in “System configuration lockdown” mode, you are not allowed to initiate any of the configuration operations from either Storage Management UI or CLI. If this mode is set, you are not allowed to perform most of the operations in Storage Management except some of the enumeration or reporting operations.
You can enable the lockdown mode from the iDRAC UI. 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 Storage Management UI.
NOTE: Storage Management does not support configuring or setting the lockdown mode from either UI or CLI. For enabling the system configuration lockdown mode, you have to access iDRAC UI or similar applications.

NOTE: Storage Management does not support system lockdown mode on PERC 12 controllers. On the PERC 12 controllers, all the tasks are enabled even when the server is in the lockdown mode.
|
NOTE: If you restart the data manager or Engine service after setting the system lockdown mode on, and then the immediate reflection on the Storage Management page happens. You might have to refresh the Storage Management UI after the restart, if required.

Storage Management CLI: Only the tasks available or supported in the UI are available or supported in the Storage Management 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!!!’
