What this option is doing is allowing the smp utilities to send SMP frames to interrogate the HBA. Setting (or not setting) this option has no effect on the SAS expanders. Essentially, it allows the HBA ports to be treated the same as the expander ports from the point of view of a software management tool. > + For more details see: > + http://www.scsita.org/aboutscsi/sas/tutorials.html It's not the whole of this, just the Management upper layer. > + http://www.t11.org/ftp/t11/pub/sm/hba/04-373v0.pdf This latter one is the HBA API ... it's not really anything to do with SMP.
