Create Persist Record using iRule

[DarioGB_339840]

Hello.

I would like to use VIP-Targeting-VIP after loadbalacing decision in conjuntion with Single Node Persistence (https://devcentral.f5.com/codeshare?sid=690).

To do so, I'm using this code.

when LB_SELECTED {

     Create persist-record to use it for future loadbalancing decisions
    persist add uie [virtual name]

     Perform VIP-Targeting-VIP base on the previous LB selection
    switch [LB::server port] {
        "1001" {
            LB::reselect virtual VS-Test_1001
        }
        "1002" {
            LB::reselect virtual VS-Test_1002
        }
    }
}

After execution, two persist entries are created

 tmsh show ltm persist persist-records | grep universal
universal  /Common/VS-Test_1000  10.130.40.180:1000  10.130.40.180:1002  (tmm: 2)
universal  /Common/VS-Test_1000  10.130.40.180:1000  10.130.40.180:1002  (tmm: 1)

But an error occurs

$ curl http://10.130.40.180:1000
curl: (56) Recv failure: Connection reset by peer

Checking LTM log file I see this message.

Nov  8 13:32:18 F5-BigIP err tmm[13383]: 01220001:3: TCL error: /Common/Rule_VS-2-VS  - Prerequisite operation not in progress (line 2) (line 2)     invoked from within "persist add uie [virtual name]"

Do you know what the reason could be? Thanks.

KR, Dario.
