.SH DESCRIPTION
.sp
.LP
The \fBsasinfo\fR utility is a command line interface that collects
administrative information on Serial Attached SCSI-2 (SAS-2) host bus adapter
(HBA) that supports the Storage Management HBA API (SM-HBA). The utility
reports attributes of HBA ports and of expander devices and SCSI target devices
that might be connected to those HBA ports.
.sp
.LP
\fBsasinfo\fR is implemented as a set of subcommands, described below.
.SH SUB-COMMANDS
.sp
.LP
The following subcommands are supported by \fBsasinfo\fR.
.sp
.ne 2
.na
\fB\fBhba\fR\fR
.ad
.sp .6
.RS 4n
Lists information for the HBA referenced by the specified \fIHBA_name\fR.  If
\fIHBA_name\fR is not specified, all HBAs on the host will be listed.
.RE

.sp
.ne 2
.na
\fB\fBhba-port\fR\fR
.ad
.sp .6
.RS 4n
Lists information for the HBA port referenced by the specified
\fIHBA_port_Name\fR.  If \fIHBA_port_Name\fR is not specified, all HBA ports on
the host will be listed. Note that HBA ports can be dynamically
configured/unconfigured so that the number of HBA ports on an HBA can change as
connections to target devices are established. With no connections to a storage
device, no HBA port is configured.
.RE

.sp
.ne 2
.na
\fB\fBexpander\fR\fR
.ad
.sp .6
.RS 4n
Lists hierarchical view of the expander referenced by the specified
\fIExpander_SAS_Addr\fR. If no argument is specified, all expanders that are
visible across all HBA ports on the host will be listed.
.RE

.sp
.ne 2
.na
\fB\fBtarget-port\fR\fR
.ad
.sp .6
.RS 4n
Lists information for those target ports referenced by
\fITarget_port_SAS_Addr\fR address. If no argument is specified, all target
ports that are visible on the host will be listed.
.RE

.sp
.ne 2
.na
\fB\fBlogical-unit\fR | \fBlu\fR\fR
.ad
.sp .6
.RS 4n
Lists the logical unit referenced by the specified \fIdevice_path\fR. If
\fIdevice_path\fR is not specified, all SAS logical units will be listed,
including the SAS Management Protocol (SMP) target port.
.RE
