Why does pacemaker stop the unpromoted resource resource when pengine reports "Pre-allocation failed"?

Issue

• The monitor operation of the PRIMARY/Master SAPHana resource failed and the cluster started the recovery process. During the recovery, the cluster reported the following problem:

  pengine:   notice: color_instance:      Pre-allocation failed: got node01 instead of node02
  pengine:     info: native_deallocate:   Deallocating rsc_SAPHana_SID_HDB00:0 from node01
  

• This resulted in the SECONDARY/Slave SAPHana resource being stopped due to the next decision taken by the cluster:

  pengine:   notice: LogAction:    * Move       rsc_SAPHana_SID_HDB00:0             ( Slave node02 -> Master node01 )  
  pengine:   notice: LogAction:    * Start      rsc_SAPHana_SID_HDB00:1             (                        node02 )  
  pengine:   notice: process_pe_message:  Calculated transition 50175, saving inputs in /var/lib/pacemaker/pengine/pe-input-2444.bz2
