3497754 - Transferring a reservation key to a new master host in HANA scale out environment.

• Finished installation of a SAP HANA Scale-Out on a TDI approach.
• Storage Connector API used during the SAP HANA installation is - fcClientLVMMpath.py(i.e. ha_provider = hdb_ha.fcClientLVMMpath in global.ini). 
  The Storage API Guide from the SAP Note:1900823, mentions about a reservation key.
  ============================================
  Further it allows automatic registration of reservation keys in case new device paths are added to a LUN or
  become active again. However, for this to work you have to add the reservation key used by SAP HANA for
  each host to /etc/multipath.conf .
  
  You can run ‘python $DIR_INSTANCE/exe/python_support/hdb_ha/hdbmount.py --reservationKey’ as sidadm on each host to get the corresponding reservation keys. 
  ============================================
