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>

Recovering iDRAC7

iDRAC7 supports two operating system images to make sure a bootable iDRAC7. In the event of an unforeseen

catastrophic error and you lose both boot paths:

• iDRAC7 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 iDRAC7, and

then reboots iDRAC7.

Using TFTP Server

You can use Trivial File Transfer Protocol (TFTP) server to upgrade or downgrade iDRAC7 firmware or install certificates.

It is used in SM-CLP and RACADM command line interfaces to transfer files to and from iDRAC7. The TFTP server must

be accessible using an iDRAC7 IP address or DNS name.

NOTE: If you use iDRAC7 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.

• Install a TFTP server on the operating system.
