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.d9 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.d9, reprograms iDRAC, and then
reboots iDRAC.
Easy Restore
Easy Restore uses the Easy Restore flash memory to back up the data. When you replace the motherboard and power on the
system, the BIOS queries the iDRAC and prompts you to restore the backed-up data. The first BIOS screen prompts you to
restore the Service Tag, licenses, and UEFI diagnostic application. The second BIOS screen prompts you to restore system
configuration settings. If you choose not to restore data on the first BIOS screen and if you do not set the Service Tag by
another method, the first BIOS screen is displayed again. The second BIOS screen is displayed only once.
