HBSIG Replaces HWID Beginning with Neverfail Heartbeat version 6.0



This Knowledgebase article provides information about Heartbeat Signature (HBSIG), which replaces the Neverfail Hardware ID (HWID or NFHWID) as the server identifier used for creating a license key for Neverfail Heartbeat version 6.0 and newer.

More Information

The HBSIG is eight alphanumeric characters that represent information about your specific machine. The first four digits of the HBSIG represent the Fully Qualified Domain Name (FQDN) and the last four digits represent the machine SID. Neverfail Heartbeat uses HBSIG to generate your license key. When HBSIG changes, your existing license key becomes invalid.

HBSIG Can Change

Upgrading to Neverfail Heartbeat version 6.0 from a previous version invalidates the license key that was generated by the previous installation because the old license key was based on the HWID.

Changes to server configuration that affect the SID and changes in the server's position in the network also can invalidate your license key by causing the HBSIG to change. Typical operations that change the HBSIG and require a new license key include:

  • Changing the name of a server in the Cluster
  • Reinstalling the operating system on the Primary or Tertiary server, unless restored from the Secondary - see the Knowledgebase articles listed below
  • Joining a server to a different domain (removing and rejoining to the same domain does not change HBSIG)
  • Adding new licensed options to your Neverfail installation

Run SCOPE to Get Your New License Key

When you make a change to your installation of Neverfail Heartbeat or to your server configuration that alters your HBSIG, run SCOPE again and upload the SCOPE data to the Neverfail Extranet to request a valid license key.

NOTE: The HBSIG is reported in the SCOPE xml data file as New Hardware ID.
