Reset Dell RAC 7 Self Signed Certificate
You need to install Dell Open Manage. Then you will have the utility racadm.
To reset the existing certificate on a DRAC card to a self signed certificate
racadm -r 10.5.9.7 -u DRACUsername -p 'DRACPAssword' sslresetcfg racadm -r 10.5.9.7 -u DRACUsername -p 'DRACPAssword' racreset
The DRAC will reset (only the DRAC – not the entire server). When it comes back on line, you will have an updated self signed certificate.
