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) Serial Management Protocol. A SAS Host Bus Adapter (HBA) includes a SMP initiator (along with SSP and STP initiators). A SAS expander contains a SMP target. Most SAS HBAs have a SMP pass through interface that can be used to send SMP requests and receive the responses. This package is designed to work with the Linux kernel (lk) 2.6, 3, 4 and 5 series; FreeBSD 9.0 (and later) and recent Solaris versions. Three interfaces are available for Linux: "sgv4", "mptctl" and "aac". The "sgv4" interface uses the bsg driver. The "aac" interface requires a recent aacraid driver and firmware in the controller. The SAS-4 standard is broken into two parts. The latest freely accessible electrical and physical part is sas410b.pdf . The upper layers are found in the "SAS Protocol Layer" (SPL) document: spl5r09.pdf . Both pdfs can be found at https://www.t10.org/ . These utilities should be SAS-4 ready. SAS-4's baud rate of 22.5 Gbps is referred to as "G5" in SPL. Note that some SAS specific utilities required for SAS management can be found in other packages. For example the sdparm utility (package name: sdparm) lists SAS VPD pages (e.g. Protocol Specific LU/Port pages) and accesses SAS mode pages (e.g. select wide port connections with the "Shared Port Control" mode page). The sg_logs utility in sg3_utils decodes several SAS specific log pages.
