DRAC Firmware update failed : Error: 30001 Method httpCgiErrorPage()

Have tried to update an old DRAC4 Firmware from firmware 1.5 to 1.75 via Linux binary and came to an unplaisant surprise :

 Dell Remote Access Controller 4/P  
 The version of this Update Package is newer than the currently installed version.  
 Software application name: Dell Remote Access Controller 4/P Firmware  
 Package version: 1.75

Doesn't look good and of course if I try to access the DRAC via HTTPs, I've got a nice CGI error :

 Error: 30001 Method httpCgiErrorPage()  

Looked on the web and somebody (who contacted Dell Support) advises to shutdown the server, unplug the DRAC card for a while and plug it in back... Well explain to your CTO that you need to shutdown a production server, unrack it, unplug a card just because a DRAC update failed o_O

The solution that worked for me was to install the racadm Dell tool on my bastion and reset the firmware remotely.

• First install racadm :

 # yum install srvadmin-racadm4.x86_64  

Note : This is for DRAC4, didn't had the issue with newer DRAC.
Note 2 : You need to have the Dell OSMA repository installed on your server:
http://www.openfusion.net/linux/dell_omsa

•  Then run the following command :

 # racadm -rDRAC_IP -i racreset  

Note : Change DRAC_IP with your DRAC IP.
Note 2 : This operation will NOT erase your DRAC configuration.

•  Wait a while, pray, and if you're lucky as me you should be back on line (with the original firmware version of course).

Final word, I stopped being lazy and updated the firmware via the Web GUI which is a long and annoying process. Of course I used Internet Explorer as I felt like Murphy's law was around this day ^^

Hope that helps !
