Last Modified: Sep 13, 2023

BIG-IP Install/Upgrade, TMOS(all modules)

Known Affected Versions:
12.1.0, 12.1.1, 12.1.2, 13.0.0

Fixed In:

Opened: Dec 06, 2016

Severity: 3-Major


when upgrading to 12.1.1, 12.1.2 or 13.0 releases, executing a command similar to curl -k -u admin:admin causes the following error: "errorMessage": "Could not connect to host Please ensure there are no licensing, firewall, port lockdown or network connectivity issues. Error: Failed to read key /config/filestore/files_d/Common_d/trust_certificate_key_d/:Common:dtca.key_12100_2: invalid header",


if your device has an iApps LX application, then that application sill not synchronize to the standby device. So if a failover occurs, then the iApps LX application will seem to disappear, and traffic will not pass through the application.


Upgrading from releases prior to 12.1.1 to 12.1.1 or 12.1.2 or 13.0


If you have upgraded and are in this condition, and you need to use iAppsLX, you can perform the following procedure to recover. Impact of procedure: this procedure disables HA and requires you to rebuild your HA environment. You only need to use this procedure if you absolutely need to run an iAppLX. 1. Reset device trust, then re-establish device trust, your device group(s), and your traffic group(s) 2. At the BIG-IP command line for each of the devices, run the following command: clear-rest-storage
