What is the Command to list all HBA adapters to ESX server
I think it's esxcfg-vmhbadevs -l what you are asking for.

What Andre said and if you want more detail info about HBA you can go into /proc/scsi/qlaxxx and there you will have files for each adapter. In those files are very datailed info about your HBA adapter.
