If a vCMP guest is configured with a high availability (HA) trunk with a threshold value greater than 0, the HA trunk configuration fails with a message similar to the following: err mcpd[5926]: 01071569:3: Ha group ha_group threshold for trunk _your_trunk_name_here_ 1 is greater than the maximum number of members 0.
HA trunks do not work. You cannot upgrade the vCMP guest to an affected version of BIG-IP or load a configuration with an HA trunk configured with a threshold value greater than 0.
This occurs when an HA trunk is configured a vCMP guest, with a threshold value greater than 0. This may occur by any of the following means: 1) Attempting to upgrade a guest to an affected version of BIG-IP, with an HA trunk configured with a threshold value greater than 0. The upgrade fails with the indicated error message. 2) Attempting to load a UCS from a guest with an HA trunk configured with a threshold value greater than 0. The UCS load fails with the indicated error message. 3) Creating an HA group and then attempting to modify the threshold value for the HA trunk. The modify command fails with the indicated error message.
To allow the upgrade to succeed or the configuration to load, configure the HA trunk threshold to 0. Important! This disables the HA trunk feature.
HA trunks with a threshold value greater than 0 are supported on vCMP guests.
