Recently I have faced a problem during the upgrade of Nexus 7K from 6.2.8a to 6.2.16. When reload the admin VDC, after changing boot-path from 6.2.8a to 6.2.16 ,its returning previous image (6.2.8a), not taking the new one (6.2.16). But in sh boot command its showing the new image after reload. What would be the cause of the issue ? Please suggest. (Looks like all other hardware, BIOS. memory circumstances are OK).
Thanks for reply but checked MD5 value for Kickstart and System images. All looks fine. We have Dual SUP2E, both SUP is having the image 6.2.16. But its still not worked. Remember we did not implemented ISSU for IOS upgrade. It was disruptive, change the boot system and reload. Please suggest.
