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.
