When facing a hardware issue, the first thing to try is to reset the server in order to restart them.
Enterprise components are designed to remain powered on 24/7 but when you face an issue, a reset of your device can make things work. There are three levels of reset:
Restart: Use the normal procedure to restart your device.
Reset: If the device is not responding to any command, press the power button for 10 seconds. Power is cut, and the device restarts.
Power Drain: As some components are still powered and do not reboot when you reset (for example the iDRAC), it is advised to perform a hard power drain if the two above procedures are not solving the issue or if some components are not responding.
Power Drain Procedure
Power the server down.
Disconnect server from all power cables, Network cables.
Hold down the power button continuously for at least 10 seconds.
Insert power cables and network cables back to the system.
Wait about 2 minutes before powering on the server for iDRAC to be initialized.
