vcmp + ha-group threshold

Hi,

I have an appliance with vcmp configured and setting up a ha-group on the guest, running 12.1 on host/guest.

2x10G Trunk is up on host and networks configured on the guest passing traffic through the vlans/trunk. When I try to set a threshold on the trunk in ha-group I get the following, which would indicate the trunk doesn't have any members?

Ha group ha-group-1 threshold for trunk t1 1 is greater than the maximum number of members 0.

I've set this up before on 11.6 and Viprion with no problems. Config snippet below.

    (tmos) list sys ha-group
sys ha-group ha-group-1 {
    active-bonus 70
    trunks {
        t1 {
            percent-up 100
            weight 100
        }
    }
}


    (tmos) show sys ha-group detail

-------------------------
Sys::HA Group: ha-group-1
-------------------------
State         enabled
Active Bonus       70
Score             100

  ------------------------------------
  | Sys::HA Group Trunk: ha-group-1:t1
  ------------------------------------
  | Threshold             0
  | Percent Up          100
  | Weight              100
  | Score Contribution  100

    Are you trying to configure this on the vCMP host or guest? Host wouldn't make much sense in my eyes, since the hosts normally operate in standalone mode, not being grouped in device groups. Concerning the vCMP guests, I'd be interested in how the physical state of the trunk member interfaces on the host will be propagated to the guest. Is this even supposed to work?

    it's configured on the guest. Yes it works at least in 11.x Viprion as I've been using it for over year on another system

    Interesting. Does "list net trunk t1" list more than 0 trunk member interfaces?

    I coincidentally just got this information from a support engineer during a support case with a different subject:

     

    During my research I have found another bug that may affect you:

     

    596104 - VCMP guest fails to load config with HA trunk configured

     

    _Symptoms:_ If a VCMP guest is configured with an HA trunk (such as, when loading such a configuration created with an earlier version of BIG-IP), the configuration load will fail 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.

     

    _Conditions:_ This occurs when loading a configuration from a VCMP guest created in a previous version that had an HA trunk configured.

     

    _Impact:_ Unable to load config with HA trunk on VCMP guest.

     

    _Workaround:_ Manually setting the HA trunk threshold to 0 will allow the configuration to load; however, this disables the HA trunk feature.

     

    There is no HF or EngHF I am aware of for the moment.

     

    This is obviously the bug you are hitting, too.
