Hi,
We have a recent new build if DNAC 2.2.3.5 and I am currently looking at IOS upgrades on cisco 2960XR switches.
I have built a stack of 4 2960XR 24_PS to upgrade the IOS and test how well DNAC performs.
Unfortunately, DNAC fails reporting the following error:
NCSW10249: Distribution failed using protocol: HTTPS.Distribution of image: c2960x-universalk9-tar.152-4.E3.tar on device. with protocol: HTTPS . Loading Image File to Device failed!. Device response error: [ Could not buffer tarfile...using multiple downloads examining image... %Error opening https://x.x.x.x/api/v1/file/temporary/268699f2-a5b9-4582-9fab-e022e2cf6ffb (I/O error) %Error opening flash:update/info (No such file or directory) ERROR: Image is not a valid IOS image archive.
Upgrades on single switches have successful.
Can anyone advise on where to start troubleshooting this ?
Thanks
