System Lockdown mode
System Lockdown mode helps in preventing unintended changes after a system is provisioned. This feature can help in
protecting the system from unintentional or malicious changes. Lockdown mode is applicable to both configuration and firmware
updates. When the system is locked down, 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.
NOTE: After the System Lockdown mode is enabled, you cannot change any configuration settings. System Settings fields
are disabled.
Lockdown mode can be enabled or disabled using the following interfaces:
iDRAC web interface
RACADM
WSMan
SCP (System Configuration Profile)
Redfish
Using F2 during POST and selecting iDRAC Settings
NOTE: To enable Lockdown mode, you must have iDRAC Enterprise license and System Control privileges.
Following are a few of the tasks that can be performed even if the system is in Lockdown mode:
Power cap setting
System power operations (power on/off, reset)
Power priority
Identify operations (Chassis or PERC)
Part replacement
Running diagnostics
Modular operations (VLan configuration, FlexAddress)
Group Manager passcode
The following table lists the functional and non-functional features, interfaces, and utilities that are affected by Lockdown mode:
NOTE:
Changing the boot order using iDRAC is not supported when lockdown mode is enabled. However, boot-control
option is available in vConsole menu, which has no effect when iDRAC is in lock down mode.
