Affected Product:  See more info
BIG-IP Install/Upgrade, LTM(all modules)

Known Affected Versions:
14.1.4.1

Opened: Apr 06, 2021
Severity: 3-Major

Symptoms

BIG-IP vCMP guests with high availability (HA) Groups that include scoring of trunk members are unable to upgrade. After rebooting into the new software version, the system will report errors similar to the following when loading the configuration: Loading configuration... Loading schema version: 13.1.3.4 /config/bigip_base.conf /config/bigip_user.conf /config/bigip.conf Loading schema version: 14.1.4.1 010712a5:3: Ha_group <HA group name> unknown trunk <trunk name>. Unexpected Error: Loading configuration process failed.

Impact

Unable to upgrade.

Conditions

-- vCMP guest using HA Groups that include scoring of trunk members. -- Upgrading to an affected version, or loading a UCS file on an affected version.

Workaround

-- Before upgrading vCMP guest to an affected version, remove all trunks from the HA Group. This should be done on the standby unit first to prevent a failover. The trunks can then be re-added to the HA Group after the upgrade. -- If already booted into an affected version, edit the /config/bigip_base.conf to add a line like the following declaring the trunk exists, and reload the configuration or reboot: net trunk <trunk name> { }

Fix Information

None
