Rollback Firmware Using RACADM
To rollback device firmware using racadm:
1. Check the rollback status and the FQDD using the swinventory command:
racadm swinventory
For the device for which you want to rollback the firmware, the Rollback Version must be
Available. Also, make a note of the FQDD.
2. Rollback the device firmware using:
racadm rollback <FQDD>
For more information, see iDRAC8 RACADM Command Line Interface Reference Guide available at

Recovering iDRAC
iDRAC supports two operating system images to make sure a bootable iDRAC. In the event of an
unforeseen catastrophic error and you lose both boot paths:
• iDRAC bootloader detects that there is no bootable image.
• System Health and Identify LED is flashed at ~1/2 second rate. (LED is located on the back of a rack
and tower servers and on the front of a blade server.)
• Bootloader is now polling the SD card slot.
• Format an SD card with FAT using a Windows operating system, or EXT3 using a Linux operating
system.
• Copy firmimg.d7 to the SD card.
• Insert the SD card into the server.
• Bootloader detects the SD card, turns the flashing LED to solid amber, reads the firmimg.d7,
reprograms iDRAC, and then reboots iDRAC.
Using TFTP Server
You can use Trivial File Transfer Protocol (TFTP) server to upgrade or downgrade iDRAC firmware or
install certificates. It is used in SM-CLP and RACADM command line interfaces to transfer files to and
from iDRAC. The TFTP server must be accessible using an iDRAC IP address or DNS name.
NOTE: If you use iDRAC Web interface to transfer certificates and update firmware, TFTP server is
not required.
You can use the netstat -acommand on Windows or Linux operating systems to see if a TFTP server is
running. The default port for TFTP is 69. If TFTP server is not running, do one of the following:
• Find another computer on the network running a TFTP service.
