The Toggle HSN step requires:
  • A minimum of Teradata 13.0 on all nodes in the system
  • All nodes in the system to be selected, and any other nodes that are not part of the system cannot be selected
  • At least one Hot Standby or Persistent Hot Standby node in the system
The options available on the Toggle HSN screen are:
Option Description
Convert HSN to Active Nodes The Convert HSN to Active nodes option converts all Hot Standby nodes to Active nodes and stores the information in a temporary file (toggleHsn_noHsn_vconfig.txt). Once selected to continue, PUT transfers these changes to the vconfig.txt file.
Select Available HSNs Some platforms allow the user to select one or more, but not all, Hot Standby nodes from the available list. This list is displayed on the PUT screen when applicable.
Restore HSN The Restore HSN option restores all original Hot Standby nodes using the backup file toggleHsn_orig_vconfig.txt.
