Bug ID 527080: Upgrade of invalid IP address or FQDN configuration.

Last Modified: Sep 13, 2023

Affected Product(s):
BIG-IP Install/Upgrade, LTM(all modules)

Known Affected Versions:
11.6.0, 11.6.1, 11.6.2, 11.6.3,,,,, 11.6.4, 11.6.5,,,

Opened: Jun 09, 2015

Severity: 2-Critical


All nodes must have unique constraints on IP address or FQDN. If a saved configuration has violated that constraint, the upgrade fails when the configuration fails validation.


Configuration fails to load on upgrade. The system posts messages similar to the following in the ltm log: ltm log: -- err tmsh[9336]: 01420006:3: Loading configuration process failed. -- emerg load_config_files: '/usr/bin/tmsh -n -g load sys config partitions all' - failed. -- 01070734:3: Configuration error: Invalid FQDN : the node already exists for (www.siterequest.com) Unexpected Error: Loading configuration process failed. -- err mcpd[7634]: 01070425:3: Full configuration load failed.


Configuration contains nodes that do not have unique IP addresses or FQDNs.


Delete duplicate IP addresses or FQDNs and retry the upgrade/load.
