Hi @Hoang Hung,

The following logs look interesting:

*** Running INXOS PE IFC image  ***
Extracting system image from kickstart
Failed to write segment to output file
Failed to read segment 5 from /bootflash/aci-n9000-dk9.13.0.2k.bin to /bootflash/auto-s
*** Succesfully extracted system image into bootflash ***

Image 'aci-n9000-dk9.13.0.2k.bin' may be corrupted on your Switch.
Could you please upload the image to the Switch again?

Before this, please confirm its MD5 matches with the official one indicated in Cisco.com

Hi @Hector Gustavo Serrano Gutierrez 

Could you please upload the image to the Switch again? => at point time, we only access to the loader for leaf switch. How do you do upload the image switch? I think that we need boot from USB at the loader point.

Hi @Hoang Hung,

Yes, please try booting the Switch using an USB flash drive.

Be aware that the USB flash drive must be formatted in FAT32 in order to be recognized by the Switch in the loader> prompt.
Example:

loader > dir                                                                  

usb1:: 
 System Volume Information
 aci-n9000-dk9.13.0.2k.bin
 aci-n9000-dk9.14.2.1i.bin
bootflash:: 
  lost+found
  bios_bootup_scratch_not_cleared

loader > boot usb1:aci-n9000-dk9.13.0.2k.bin       
Booting usb1:aci-n9000-dk9.13.0.2k.bin
Trying diskboot
 Filesystem type is fat, partition type 0xc


# Once your Switch has booted up, set the bootvar accordingly.
