Infrastructure lock (also known as iDRAC lockdown mode or system lockdown mode) helps in preventing 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 the server or cluster hardware updates using OpenManage Integration extension.
Enable or disable infrastructure lock
To enable or disable the Infrastructure lock in
Dell OpenManage Integration extension, go to the
Action tab, under
SECURITY, select
Infrastructure Lock. The Infrastructure Lock page appears. Click
Enable or
Disable. The Infrastructure Lock page can also be accessed from
page.
To perform server or cluster management operations such as server update, CAU, full stack update, Manage CPU cores, and so on, the infrastructure lock needs to be disabled. If the lock is already enabled, the extension displays an error during the management operation and gives an option in the same window to disable the lock and proceed next. To allow the extension automatically locks the infrastructure after the operation is complete, select
Allow OMIMSWAC to re-enable the infrastructure lock after the operation is complete. Automatic reenabling of the infrastructure lock is available on PowerEdge servers with iDRAC firmware version 4.40.00.00 and above.
In case of scheduled reboot, if the infrastructure lock is enabled during cluster reboot, the reboot operation fails. Ensure that the infrastructure lock is disabled before the schedule reboot begins for a successful update.
To disable the infrastructure lock during server or cluster management operation on PowerEdge servers with iDRAC version lower than 4.40.00.00, go to the
Action tab, under
SECURITY, select
Infrastructure Lock, and then click
Disable.
NOTE: OpenManage Integration extension does not allow enabling or disabling the infrastructure lock for servers that are part of a cluster to maintain cluster homogeneity.
