Sometimes those pesky DRAC cards in the Dell servers just seem to not respond or act up. If you still have CLI access to it, you can reset it a two different ways.
If you are local to the machine, and it has OpenManage installed (OMSA), use this command to perform a soft-reset:
c:racadm racreset soft
It will acknowledge that it has completed and you have to wait a few minutes.
If you are remote you need to have the DRAC tools installed, and credentials to use the command:
This will perform a “soft” reset, or a power cycle. No settings will be lost or changed.This is useful as the DRAC operates independently of the server and does not power cycle when the server does.
If the settings on the DRAC have become corrupted and you need to reset it to factory settings, the command is as follows:
This reset will set everything back to factory defaults. You will lose connection remotely as it will also reset the DRAC back to the default IP scheme.
