Symptoms

In a meshed IB Fabric, OpenSM never comes out of Discover state to Master or Standby for either of the two Fabric Interconnects:

Changes

Found when moving from two separate IB Fabrics (both Fabric Interconnects configured as OpenSM master - not meshed) to moving to meshed IB Fabric (OpenSM master and Standby)   Following instructions to set subnet manager faslse (#set system is-subnet-manager false), and then running "guid2lid" to zero out the lid table, resulted in one or both Fabric Interconnects staying in "Discover" state.
