System Lockdown Mode
The System Lockdown Mode feature is available in iDRAC for 14th generation of the PowerEdge servers. This feature when
enabled locks the system configuration modification tasks. This feature is intended to protect the system from unintentional
changes.
You have to set theiDRACLockDownMode variable in the task sequence during Operating System Deployment.
When the System Lockdown Mode is enabled, the following functionalities have limitations:
● All system configuration modification tasks; Set operation cannot be performed.
● OS deployment
NOTE:
○ To restrict OS deployment in System Lockdown Mode, you need to add iDRACLockDownMode variable with
value 0 in the deployed section of task sequence. To add the iDRACLockDownMode variable, see Adding
iDRACLockDownMode variable.
○ Do not set the iDRACLockDownMode variable in the task sequence during Operating System Deployment for the
following scenarios:
￭ DSDP does not check for the System Lockdown Mode feature, and continues with OS deployment if no hardware
configuration is selected.
￭ DSDP does not check for the System Lockdown Mode feature, and continues with OS deployment in presence of
a CAB file.
