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.
Backing up server profile
You can back up the system configuration, including the installed firmware images on various components such as BIOS, RAID,
NIC, iDRAC, Lifecycle Controller, and Network Daughter Cards (NDCs) and the configuration settings of those components. The
