\fBscsi_id\fP is primarily for use by other utilities such as \fBudev\fP
that require a unique SCSI identifier.

.SH OPTIONS
.TP
-.BI subsystem
-When called with only a single argument without a leading \-, runs in a hotplug
-mode, and expects the environment variable DEVPATH to specify the
-corresponding sysfs device. See section below on usage with \fBudev\fP.
-.TP
-.BI \-b
+.BI \-\-blacklisted
The default behaviour \- treat the device as black listed, and do nothing
unless a white listed device is found in the scsi_id config\-file.
.TP
-.BI \-d "\| device\^"
-Instead
-of determining and creating a device node based on a sysfs dev
-entry as done for the \fB\-s\fP, send SG_IO commands to
-\fBdevice\fP, such as \fB/dev/sdc\fP.
+.BI \-\-device=\| device\^
+Send SG_IO commands to \fBdevice\fP, such as \fB/dev/sdc\fP.
.TP
-.BI \-f "\| config\-file"

Read configuration and black/white list entries from

rather than the default
.B /etc/scsi_id.config
file.
.TP
-.BI \-g
-Treat the device as white listed. The \fB\-g\fP option must be specified
+.BI \-\-whitelisted
+Treat the device as white listed. The \fB\-\-whitelisted\fP option must be specified
on the command line or in the scsi_id configuration file for
.B scsi_id
to generate any output.
.TP
-.BI \-i
-Prefix the identification string with the driver model (sysfs) bus id of
-the SCSI device.
+.BI \-\-page=\| 0x80 | 0x83 | pre-spc3-83
+Use SCSI INQUIRY VPD page code 0x80, 0x83, or pre-spc3-83.
+.sp
+The default
+behaviour is to query the available VPD pages, and use page 0x83 if found,
+else page 0x80 if found, else nothing.
+.sp
+Page pre-spc3-83 should only be utilized for those scsi devices which
+are not compliant with the SPC-2 or SPC-3 format for page 83. While this
+option is used for older model 4, 5, and 6 EMC Symmetrix devices, its
+use with SPC-2 or SPC-3 compliant devices will fallback to the page 83
+format supported by these devices.
.TP
-.BI \-p "\| 0x80 | 0x83"

-if found, else nothing.

+Reformat the output : replace all whitespaces by underscores.
.TP
-.BI \-s "\| sysfs\-device"
-Generate an id for the

-.SH USAGE WITH UDEV
-If \fBscsi_id\fP is invoked with one argument without a leading \-, it
-assumes it is called for a hotplug event, and looks for the sysfs device
-in the DEVPATH environment variable.
-
-This mode is used when run via the \fBudev\fP PROGRAM key. Passing any
-arguments or options as part of the PROGRAM rule breaks this assumption,
-and the results will likely not be as expected.
-
-When in this mode, all errors and warnings are sent via syslog.
-
-To determine the specific value needed in a RESULT key, use the \-s option,
-for example:
-
-.sp
-.nf
-/sbin/scsi_id -s /block/sda
-.fi
-.P
-
-An example \fBudev\fP rule using \fBscsi_id\fP, that will name a block
-device and any partitions for the device matching the \fBscsi_id\fP output
-of 312345:
-
-.sp
-.nf
-BUS="scsi", PROGRAM="/sbin/scsi_id", RESULT="312345", NAME="disk%n"
