To perform OS10 upgrade using CLI use below steps:

  1. For download the appropriate image for the switch using Dell Digit locker ( https://www.dell.com/SUPPORT/SOFTWARE/ )
  2. Download OS10 Enterprise Edition image, from the site in tar file format for the upgrade.
  3. Take configuration backup of current running config from exec mode 
    copy running-configuration startup-configuration
    

    copy config://startup.xml config://<backup file name>
  4. Check the ONIE kernel version version in use: 
    system "file /mnt/onie-boot/onie/vmlinuz*"
  5. Only if ONIE kernel version is 4.x.x proceed further with OS 10 upgrade using further steps
  6. Extract the downloaded tar file in above steps to get binary image
  7. Download the image (Only downloads, does not installs) to OS 10 switch using: 
    image download file-url
    For example scp from a remote Linux machine 
    image download scp://userid:passwd@hostip:/filepath
  8. Check image status 
    show image status
  9. Only if running OS10 release 10.5.0.x or earlier and installing 10.5.2.0 or later now 
    image cancel
  10. Get the path of images on the system 
    dir image
  11. Install the 10.5.2.6 or later software image in EXEC mode. 
    image install image-url
    For example: 
    image install image://filename.bin
  12. See image status and boot detail 
    show image status
    

    show boot detail
  13. Reload switch based on previous and new OS versions
    1. If System is presently running an OS10 release earlier than 10.5.1.0 and you are installing 10.5.1.9 or later 
      reload
    2. System is presently running OS10 release 10.5.1.0 or later and you are installing 10.5.2.6 or later now 
      boot system standby
      

      show boot detail
      

      reload
  14. After reboot switch automatically goes to ONIE -> ONIE update mode and updates CPLD, BIOS, Firmware etc.
  15. After update check version 
    show version
  16. (Optionally) If you do not want to failback to older version and want both active and standby OS to be of the upgraded version then use: 
    show boot detail
    

    image copy active-to-standby
    

    show boot detail
