Description (partial)

FEX image being deleted. This will cause the FEX to boot up in ROMmon if no other backup image is stored in flash.

After an issu runversion fex all, the FEX system crashes or loses SDP connection with the parent. This causes a reset of the FEX system. Once the FEX comes back up, we've lost the ISSU state for the FEX and it initiates a standard auto-image download. 

At this state, if you abort the ISSU using issu abortversion, the FEX is reset and it deletes the original image.
