Nexus 7K upgrade failed Return code 0x40930011 (Image verification)

[AngelMorales]

I have a 7010 running code 6.2.18 Im trying to upgrade to 6.2.24.  The compatibility check on the binary file passes.  When I try to install the kickstart and ios I get the error :

NP7kTop# install all kickstart bootflash:n7000-s1-kickstart.6.2.24a.bin system bootflash:n7000-s1-dk9.6.2.24a.bin
Installer will perform compatibility check first. Please wait.

Verifying image bootflash:/n7000-s1-kickstart.6.2.24a.bin for boot variable "kickstart".
[# ] 0% -- FAIL.
Pre-upgrade check failed. Return code 0x40930011 (Image verification failed).

Yes: I have double checked that the md5sum matches

Yes: I have checked that there is space in the /nxos/tmp directory

Yes: I have failover the supervisors

Yes: no call home is enabled

Anyone have any ideas what else I need to check to get passed this?

thanks!

@AngelMorales It looks like the image verification is failing despite the MD5 checksum matching. A few things you can try:

1. Re-upload the image – Even if the MD5 matches, the file might have been corrupted during transfer. Use SCP or SFTP to re-upload it and try again.
2. Check Bootflash Integrity – Run dir bootflash: and show system integrity to check for any filesystem corruption. If needed, format bootflash and re-upload the images.
3. Verify Image Signing – If your device enforces image signing, ensure the image is properly signed and not modified.
4. Check Logs for Details – Run show install all impact kickstart <image> system <image> to get more detailed errors.
5. Try a Different Upgrade Method – Instead of install all, manually set the boot variables (boot kickstart and boot system) and reload.

If none of these work, consider trying an intermediate upgrade step (e.g., 6.2.20) before going to 6.2.24.

Thanks for the help, in the end I did have to do an intrusive reboot to get it to 6.2.20 but after that I was successfully able to utilize the ISSU functionality to update all the way to 7.3.x.  I hope to find the time to get it to 8.x in the near future. 

thanks!

thanks, I will go thru each of these steps!
