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.
