I have installed ESXi booting from SD card on B200-M3 blade. Curious to know if there is a bad blade can I perform a service profile mobility to a similar blade, without reinstalling the OS?
If you only have the OS installed in the SD card, I do not see any issues if you move the SD card to another blade and then move the SP to that other server. That will be like having the OS on local disks, replace the motherboard and move the disks to another blade (i.e an RMA)
See this thread for a known issue that was affecting the blades with SD cards:
