Infrastructure lock (also known as iDRAC lockdown mode or system lockdown mode) helps to prevent unintended changes after a system is provisioned. Infrastructure lock is applicable to both hardware configuration and firmware updates. When the infrastructure is locked, any attempt to change the system configuration is blocked. If any attempts are made to change the critical system settings, an error message is displayed. Enabling infrastructure lock also blocks server or cluster firmware updates using the OpenManage Integration extension tool.
The following table lists the functional and nonfunctional features that are affected when the infrastructure lock is enabled:
