Understanding VMHBAs

$
0
0

Details of my ESXi server:

  • HP BL660c Gen8
  • 2 HBAs
  • ESXi 5.1

 

Virtual Connect shows 2 HBA cards and WWPNs of them. But vSphere client shows 4 HBA cards and 8 different WWNs. My questions are:

  • Why vmhba0 and 1 has 2 WWNs each?
  • What are vmhba32 and 33?
  • Why all LUNs are connected with vmhba32 and 33 instead of vmhba0 and 1?
