NimbostratusLB_reselect
when LB_SELECTED {
if { $retries >= 1 } {
log local0. "befor is [LB::server addr]"
LB::reselect pool pol_name
log local0. "after is [LB::server addr]"
}
}
in the above rule I found that the lb server chosen is the same as the one after the reselect action (the VIP has cookie presistance) but I tried to remove the presistance but it has no effect on the behavouir
so I need help here how can I force the selection of other pool members

Hi,
What is your BIGIP version ?
There was a bug in some version where if you have only two servers it kept selecting the same again.
engtmkProduct: BIG-IP
Version: 9.4.1
Build: 34.0
Edition: Hotfix HF1
Built: 070816113623
if ther is a bug is there is a solution for this problem as our topolgy is 2 servers- Nicolas_MenantExtract from the release of v9.4.4:
Load-balancing reselect loops in TMM (CR85186)
In the case of two members in a Local Traffic Manager pool, the iRule command LB::reselect now selects the next pool member if the first pool member is unavailable, which prevents an infinite loop condition.
So an upgrade to this version should fix your issue - engtmkokay so now is 9.4.4 can work from flash mem or it has to run from HDD,
also what if the upgrade is not applicable what workaround can be done
