A PowerEdge 14G server administrator has to shut down a server for urgent intervention. They don't want to risk any data loss but don't know the OS password. What steps should be taken?

The correct choice in this scenario is to connect to iDRAC and use the Dashboard tab to click on Graceful Shutdown. This method ensures that the operating system can properly close all running applications, complete any ongoing processes, and safely write data to disk before the hardware is powered down.

Using the Graceful Shutdown option is critical in avoiding data corruption or loss that could result from an abrupt power-off scenario. This approach allows the OS to manage its services and file systems effectively, reducing the likelihood of issues when the server is powered back on.

In contrast, other options could lead to complications. For example, sending an OS shutdown command through the Lifecycle Controller might not work effectively if the administrator cannot access the OS due to the lack of a password. Similarly, selecting the Power Off System option would force an immediate shutdown, which could result in data loss or corruption as this method does not allow the operating system to prepare for an orderly shutdown. Properly managing the shutdown process is crucial, especially when urgent intervention is required, making iDRAC's Graceful Shutdown the best choice.
