• In the previous partition /host/prev-partition/var/lib/avi/log/Portal-webapp.log, we will find that the configuration import failed while importing the IpamDnsProviderProfile.

Cause

As part of V6 management support for Infoblox, a check was added in the pb_default.py script. However, this check skipped a condition for handling Infoblox's server address when specified using a Fully Qualified Domain Name (FQDN).

Resolution

Temporary Workaround:

Replace the FQDN in the Infoblox IPAM/DNS profile with the server IP address.

Permanent Fix:

Perform the upgrade to the following versions where the fix has been applied:

30.2.2

30.2.1-2p1
