Unluckly, I forgot my dell server R720 IDRAC password,now ,I can't login it . How to reset the IDRAC password.

Henry,

      There is two way to reset iDRAC password.

1. Reboot your server. While booting Press F2 to go to BIOS. Then traverse to iDRAC Settings. Here you will get an option to reset root password
2. Install OMSA on your server and run below racadm command to reset root password

racadm set idrac.users.2.password

Thanks for your answer.

I will try it ,then returns the result.

Hi Shine,

I tried above command line but getting syntax error.  

The syntax of the command is incorrect.

Could you suggest what is going wrong. Thanks

Can you run below command and let me know what is current iDRAC FW Version installed on the server

racadm getsysinfo -r

Also let me know what is the racadm version

You can try below command as well to set the iDRAC password 

racadm config -g cfguseradmin -i 2 -o cfgUserAdminPassword

Worked for me.

Thx!

not worked for Firmware Version = 6.10.00.00

The command "racadm config" entered is not supported on iDRAC "4.40.00.00" and later versions.
Run the "racadm set" command to complete the "configuring iDRAC configuration parameters" operation.
