Querying HBA information under Linux

To check the HBA cards installed on your system, check lspci

root@linux:~ # lspci | grep -i fibre
13:01.0 Fibre Channel: Emulex Corporation Thor-X LightPulse Fibre Channel Host Adapter (rev 01)
13:02.0 Fibre Channel: Emulex Corporation Thor-X LightPulse Fibre Channel Host Adapter (rev 01)

You can query various information using systool
