To troubleshoot HSNs, access the following logs:

Log Type Action
Standard log file
  1. From inside the VM, switch to the root user environment.
    # sudo su -
  2. Access the standard log file1.
    # /var/log/tdc-hotstandby.log
HSN daemon
  1. From inside the VM, switch to the root user environment.
    # sudo su -
  2. Access the HSN daemon.
    # /var/log/tdc-hsn-launch.log
Diagnostic logs
  1. From the Azure console, go to the diagnostic storage account that starts with diag.
  2. Look for Blobs > teradata > HSN and access tdc_hotstandby_timestamp.log to get the log of any operation.

A separate log is created each time you scale out or scale in.

1Each time you run the standard log file, the system saves the latest operation to /var/log/HSN/tdc-hotstandby.log and renames the current log file to /var/log/HSN/tdc-hotstandby.log.operation_number , where operation_number indicates how many operations were performed to the file.
For example:
  • On the first run, the system saves the latest operation to .log.
  • On the second run, the system renames .log to .log.1 and saves the latest operation to a new .log file.
  • On the third run, the system renames .log to .log.1, renames .log.1 to .log.2, and saves the latest operation to a new .log file.
