What are vHBA or virtual HBA?

Solution Unverified - Updated -

Issue

  • RHEL 6.3 What's New document states that:
"Automatically World Wide Port Names 
The ability to automatically generate unique World Wide Port Names (WWPN) and World Wide 
Node Names (WWNN) for virtual Host Bus Adapters (vHBAs) is also new in the 6.3 release. 
When KVM assigns unique WWPNs and WWNNs to the vHBAs, the device XML is automatically 
updated with the necessary information. This feature grants the benefit of automatic 
generation of names that is scriptable, eliminating a time-consuming, error-prone 
manual process. "
  • Does "vHBAs" refer to virtual FC, or virtual SCSI adapter, or both?
