An SE in partitioned (OPER_PARTITIONED) state indicates that the SE is disconnected from the NSX Advanced Load Balancer Controller, but some virtual services are still operational on that SE. This section explains the conditions when the SE is in OPER_PARTITIONED mode and when the SE is in OPER_DOWN state.
An SE stays in partitioned (OPER_PARTITIONED) state until one of the following conditions is met:
The SE is down because of the missed datapath heartbeats.
The cloud connector detects that the SE is powered down, or deleted from the cloud.
All the virtual services have been gracefully migrated from the SE in the partitioned state to the SEs which are fully operational.
An SE is marked down, or it goes to OPER_DOWN state due to one of the reasons mentioned below:
When none of the virtual services is operational on the SE.
The SE is not reachable from the NSX Advanced Load Balancer Controller.
When vSphere High Availability is enabled, if the Controller detects that a vSphere host failure has occurred, SEs will transition to OPER_PARTITIONED or OPER_DOWN prior to missing six consecutive heartbeat misses.
SEs (on the failed host) which have operational virtual services will transition to OPER_PARTITIONED state.
SEs (on the failed host) which do not have any operational virtual services will transition to OPER_DOWN state.
