smp_utils is a package of command line utilities for invoking
SMP functions to monitor and manage SAS expanders. SMP is the
Serial Attached SCSI (SAS) Management Protocol (SMP). A SAS Host
Bus Adapter (HBA) includes a SMP initiator (along with a SSP and
STP initiator). A SAS expander contains a SMP target.
Previous versions have supported two interfaces: the "mptctl"
pass through used by MPT Fusion SAS HBAs and the "smp_portal"
sysfs attribute pass through used by Luben's aic94xx driver.
This beta adds preliminary support for an interface based on
the scsi generic version 4 ("sgv4") interface. It works, apart
from a few shortcomings, with the MPT Fusion SAS driver found
in lk 2.6.24-rc4 . My aic94xx based hardware refuses to
work with the mainline driver (but works with Luben's
driver) so I'm unable to test it with the "sgv4" interface. I
would be grateful if someone would test it and tell me how it
fairs. Since the sgv4 interface essentially talks to the
linux SAS transport layer, other SAS HBAs may work as well.
