GSLB Service is a LB Virtual Server. This LB Virtual Server has a backup Virtual Server defined. This LB Virtual Server is Down and the GSLB Service State is Down, but the GSLB Service Effective State is UP.

Select Consider Effective State of GSLB Virtual Server to state-only.


Explanation of Consider Effective State Option
If the primary state of all bound GSLB services is DOWN, consider the effective states of all the GSLB services, obtained through the Metrics Exchange Protocol (MEP), when determining the state of the GSLB virtual server. To consider the effective state, set the parameter to STATE_ONLY. To disregard the effective state, set the parameter to NONE.

The effective state of a GSLB service is the ability of the corresponding virtual server to serve traffic. The effective state of the load balancing virtual server, which is transferred to the GSLB service, is UP even if only one virtual server in the backup chain of virtual servers is in the UP state.

Problem Cause

It is expected behavior in the default configuration of GSLB vServer under the conditions described. The behavior can be modified by toggling the Effective State on the GSLB Virtual Server.
