-.Sh DESCRIPTION
-The
-.Nm
-command configures logical units within the SCSI Target Mode Framework
-.Pq STMF
-framework.
-The framework and this man page use the following terminology:
-.Bl -tag -width Ds
-.It Sy initiator
-A device responsible for issuing SCSI I/O commands to a SCSI target and logical
-unit.
-.It Sy target
-A device responsible for receiving SCSI I/O commands for a logical unit.
-.It Sy logical unit
-A device within a target responsible for executing SCSI I/O commands.
-.It Sy logical unit number
-The identifier of a logical unit within a target.
-.It Sy host group
-An host group is a set of one or more initiators that are combined for the
-purposes of being applied to a
-.Sy view
-.Pq see below .
-An initiator cannot be a member of more than one host group.
-.It Sy target group
-A target group is a set of one or more SCSI target ports that are treated the
-same when creating a
-.Sy view
-.Pq see below .
-The set of logical units that a particular SCSI initiator can see is determined
-by the combined set of views.
-.Pp
-Each logical unit has a set of view entries, and each view entry specifies a
-target group, host group, and a LUN.
-An initiator from that host group, when connecting through that target group, is
-able to identify and connect to that logical unit using the specified LUN.
-You can use views to restrict the set of logical units that a specific initiator
-can see, and assign the set of LUNs that will be used.
-.It Sy view
-A view defines the association of a host group, a target group, and a logical
-unit number with a specified logical unit.
-Any view entry added to a logical unit must not be in conflict with existing
-view entries for that logical unit.
-A view entry is considered to be in conflict when an attempt is made to
-duplicate the association of any given host, target and logical unit number.
-.El
-.Ss Logical Unit Properties
-The following logical unit properties can be set only when creating LU using
-.Cm create-lu
-subcommand:
-.Bl -tag -width Ds
-.It Sy blk Ns = Ns Ar num
-Specifies the block size for the device.
-The default is 512.
-.It Sy guid Ns = Ns Ar string
-32 hexadecimal ASCII characters representing a valid NAA Registered Extended
-Identifier.
-The default is set by the STMF to a generated value.
-.It Sy meta Ns = Ns Ar path
-Metadata file name.
-When specified, will be used to hold the SCSI metadata for the logical unit.
-There is no default.
-.It Sy oui Ns = Ns Ar string
-Organizational Unique Identifier.
-Six hexadecimal ASCII characters representing the IEEE OUI company ID
-assignment.
-This will be used to generate the device identifier
-.Pq GUID .
-The default is
-.Sy 00144F .
-.It Sy pid Ns = Ns Ar string
-16 bytes ASCII string defining Product ID per SCSI SPC-3.
-This value will be reflected in the Standard INQUIRY data returned for the
-device.
-The default is
-.Sy COMSTAR .
-.It Sy serial Ns = Ns Ar string
-Serial Number.
-Specifies the SCSI Vital Product Data Serial Number
-.Pq page 80h .
-It is a character value up to 252 bytes in length.
-There is no default value.
-.It Sy vid Ns = Ns Ar string
-8 bytes ASCII string defining Vendor ID per SCSI SPC-3.
-This value will be reflected in the Standard INQUIRY data returned for the
-device.
-The default is
-.Sy SUN .
-.El
-.Pp
-The following logical unit properties can be set when creating LU using
-.Cm create-lu
-subcommand or modified using
-.Cm modify-lu
-subcommand:
-.Bl -tag -width Ds
-.It Sy alias Ns = Ns Ar string
-Up to 255 characters, representing a user-defined name for the device.
-The default is the name of the backing store.
-.It Sy mgmt-url Ns = Ns Ar string
-Up to 1024 characters representing a Management Network Address URL.
-More than one URL can be passed as a single parameter by using space-delimited
-URLs enclosed inside a single pair of quotation marks
-.Pq Sy \(dq .
-.It Sy wcd Ns = Ns Sy true Ns | Ns Sy false
-Write-back cache disable.
-Determines write-back cache disable behavior.
-The default is the write-back cache setting of the backing store device
-specified by the
-.Ar lu-file
-argument.
-.It Sy wp Ns = Ns Sy true Ns | Ns Sy false
-Write-protect bit.
-Determines whether the device reports as write-protected.
-The default is
-.Sy false .

-.Ar lu-name
-.Xc
-Add a logical unit view entry to a logical unit
-.Ar lu-name ,
-where
-.Ar lu-name
-is the STMF name for the logical unit as displayed by the
-.Cm list-lu
-subcommand.
-The
-.Cm add-view
-subcommand provides the user with a mechanism to implement access control for a
-logical unit and also provides a means of assigning a logical unit number to a
-logical unit for a given set of initiators and targets.
-A logical unit will not be available to any initiators until at least one view
-is applied.
-Each view entry gets assigned an entry name, which can be used to reference the
-entry in the
-.Cm list-view
-and
-.Cm remove-view
-subcommands.
-.Bl -tag -width Ds
-.It Fl h Ns \&, Ns Fl -host-group Ar host-group
-.Ar host-group
-is the name of an host group previously created using
-.Cm create-hg
-subcommand.
-If this option is not specified, the logical unit will be available to all
-initiators that log in to the STMF framework.
-.It Fl n Ns \&, Ns Fl -lun Ar lu-number
-.Ar lu-number
-is an integer in the range 0-16383 to be assigned to the logical unit for this
-view entry.

-STMF framework.
-.It Fl t Ns \&, Ns Fl -target-group Ar target-group
-.Ar target-group
-is the name of a target group previously created using
-.Cm create-tg
-subcommand.

-.Op Fl s Ar size
-.Ar lu-file
-.Xc
-Create a logical unit that can be registered with STMF.
-.Ar lu-file
-is the file to be used as the backing store for the logical unit.
-If the
-.Fl s
-option is not specified, the size of the specified
-.Ar lu-file
-will be used as the size of the logical unit.
-.Pp
-Logical units registered with the STMF require space for the metadata to be
-stored.
-When a
-.Sy zvol
-is specified as the backing store device, the default will be to use a special
-property of the
-.Sy zvol
-to contain the metadata.
-For all other devices, the default behavior will be to use the first 64k of the
-device.
-An alternative approach would be to use the
-.Sy meta
-property in a
-.Cm create-lu
-subcommand to specify an alternate file to contain the metadata.
-It is advisable to use a file that can provide sufficient storage of the logical
-unit metadata, preferably 64k.
-.Bl -tag -width Ds
-.It Fl p Ns \&, Ns Fl -lu-prop Ar property Ns = Ns Ar value
