This is a package of command line utilities. Each utility sends a Serial Attached SCSI (SAS) Serial Management Protocol (SMP) request to an SMP target. If the request fails then the error is decoded. If the request succeeds then the response is either decoded, printed out in hexadecimal or output in binary. This package was written using the Linux 2.6 and 3 series; it has been ported to FreeBSD and Solaris. For specific information about Linux see README.linux; for FreeBSD see README.freebsd and for Solaris see README.solaris . See COVERAGE file for more information about the coverage of various SMP functions. Each utility in the smp_utils package has a corresponding man page. These are found in the doc directory. Additionally there is 'smp_utils' man page that contains common information, including options used by most or all utilities plus the various exit status values. There is also a Linux specific 'bsg_sas_smp.txt' file that discusses the use of the bsg driver to send SMP requests. There are examples of setting up and disabling zoning in the examples directory.
