Opened: Oct 09, 2018

Severity: 3-Major


Upgrade of the BIG-IP system fails.


Inability to upgrade. Note: Setting hostname in tmsh CLI does not validate FQDN like the GUI does, so when you use tmsh to set hostnames, make sure to use an FQDN-compliant one.


BIG-IP systems that contain hostnames that do not meet FQDN standards. For instance, this could be due to the use of invalid characters, such as asterisk '*'. An example of an invalid hostname is as follows: test***.example.com.


When attempting to upgrade you must make sure all hostnames are FQDN compliant.
