Solutions
Task 1 Solution: Locating the current NIOS version
The current NIOS version number can be found in the file config.txt:
CLIENT_VERSION=8.5.3-417434In other words, since this is a failed upgrade, we tried to upgrade from 8.5.3 to some other version, but it failed.
Task 2 Solution: Upgrade failure cause
The upgrade failure messages recorded in system logs, which can be found in the file infoblox.log. Searching this file for the keyword ‘upgrade’ or ‘Upgrade’, and you will see the following entries:
[2021/08/17 18:31:28.292] (2448 /infoblox/one/bin/verify_upgrade_file) : Upgrade path not found for this upgrade
[2021/08/17 18:31:28.490] (20491 /usr/bin/httpd) one/grid_upgrade.py:685 _grid_upgrade_exception(): error : Upgrade path not found for this upgradeAlthough there are 3 entries, they reflect the same reason for the failed upgrade: upgrade path not found for this upgrade.
