Re: We had installed esxi 5.5 on a IBM server's . Esxi was successfuly installed and HBA physical were present on the server. When we are checking the storage adpter. There is no HBA adapter in OS.

Hello,

sry i'am confused.

So on you're Esxi you see below  Configuration > Storage Adapters   you're HBA right?

if you say "OS"  you mean you don't see hba inside a OS from a VM? 

As Pass-Through is not aktiv by default - you never will see a Host Hardware nativly inside the VM OS.

thx
