Doubt about "min-up-member" when LB is ratio-member

Hi all,

 

does anyone know why in some cases, after configuring several ltm pool, using ratio-member as lb mode, when you check the bigip.conf file, you can see in some cases, after min-active-member configuration, it appears "min-up-members" and in other cases it doesn´t.

 

Because I´m sure I didn´t configure this sentence at all.

 

We are using 11.6.0

 

Many thanks in advance.

 

Kind Regards.

  • Hi Victor,

    the

    min-active-members
    (Priority Based Activation Configuration) and the
    min-up-members
    (Failsafe configuration) settings are completely distinct from each other. You may read TMSH's command syntax help for further information and or read the online manuals for Priority Based Activation Configuration and Failsafe configurations

    [user@hostname:Active:Standalone] ~  tmsh modify /ltm pool * ?

    min-active-members

    Specifies the minimum number of members that must be up for traffic to be confined to a priority group when using priority-based activation. The default value is 0 (zero). An active member is a member that is up (not marked down) and is handling fewer connections than its connection limit.

    min-up-members

    Specifies the minimum number of pool members that must be up; otherwise, the system takes the action specified in the min-up-members-action option. Use this option for gateway pools in a redundant system where a unit number is applied to a pool. This indicates that the pool is only configured on the specified unit.

    min-up-members-action

    Specifies the action to take if the min-up-members-checking is enabled and the number of active pool members falls below the number specified in min-up-members. The default value is failover.

    min-up-members-checking

    Enables or disables the min-up-members feature. If you enable this feature, you must also specify a value for both the min-up-members and min-up-members-action options.

    Cheers, Kai
