ISE Upgrade problem

Bruno Rangel — Mon, 11 Mar 2019 06:29:00 GMT

I was trying to upgrade ISE in standalone deployment from 1.2.1.198 to 1.3

- My file name and size is same as what I see in the cisco.com download section (name: ise-upgradebundle-1.2.x-to-1.3.0.876.repackaged.x86_64.tar.gz, size: 4.02 GB (4,326,538,352 bytes))
- I used following commands and both gave the same error:

application upgrade prepare ise-upgradebundle-1.2.x-to-1.3.0.876.repackaged.x86_64.tar.gz UPGRADE
application upgrade ise-upgradebundle-1.2.x-to-1.3.0.876.repackaged.x86_64.tar.gz UPGRADE

ISE-STANDALONE# application upgrade ise-upgradebundle-1.2.x-to-1.3.0.876.repackaged.x86_64.tar.gz UPGRADE

% Please confirm above crypto hash matches what is posted on Cisco download site.

Downlod file size and MD5 exact as Ciscos published, but the SHA is diferent::
Cisco download site show SHA512 Checksum:ea2e5eee527c145eb971e2a7806e6185

The ISE showing: sha256: 461a0931c2f498399d96f195b1ab3d196fe7694f6e0cc2b4cb75928aced5f1c7

Can someone please advise what is wrong with the above steps or how to fix the above error.?

Verify your SHA512 hash

Verify your SHA512 hash matches using an external check (like http://download.cnet.com/MD5-SHA-Checksum-Utility/3000-2092_4-10911445.html ).

Then use the same utility to compute the SHA256 before transferring the file to ISE. Use that to verify.

Hi Marvin

Thanks for your reply...

I did it using the Checksum Utility, the results are the same that the ISE gave me. The question here is how I can to proceed the upgrade once the ISE just check the SHA and the file is not compatible.

My point was that the cisco

My point was that the cisco.com site is now using SHA512 hashes.

The older Linux that your ISE 1.2 uses computes using a SHA256 hash.

As long as you've confirmed the SHA256 value by computing it against a SHA512-verified file download, you can safely accept it and proceed with the upgrade.
