NAME
     libstmf - SCSI Target Mode Framework library

SYNOPSIS
     cc [ flag... ] file... -lstmf [ library... ]
     #include 


DESCRIPTION
     Functions in this library provide  configuration  management
     of  the  SCSI Target Mode Framework (STMF), allowing clients
     to manage the provisioning of logical units and  targets  to
     the initiator clients of the framework.

  Definitions
     Host Group

         A Host Group is a set of one  or  more  initiator  ports
         that  are combined together for the purposes of applying
         access controls to a Logical Unit object and assigning a
         logical  unit  number  to the Logical Unit. The assigned
         logical unit number will be reported to the  members  of
         that  Host  Group  via the SCSI REPORT LUN command. Host
         Groups can contain initiator ports that are not  visible
         to the SCSI Target Mode Framework. Initiator ports might
         not be a member in more than one group. A Host Group  is
         associated  with  a given Logical Unit via a view entry.
         Host Group names are unique within the framework.


     Logical Unit

         A Logical Unit object is provided  to  the  SCSI  Target
         Mode  Framework  for the purposes of executing SCSI com-
         mands.  Library  clients  can  manage  a  Logical   Unit
         object's  accessibility  to  one  or more SCSI initiator
         clients. libstmf library clients cannot  add  or  remove
         Logical Unit objects from the system. Every Logical Unit
         object within the SCSI Target Mode Framework is owned by
         a  logical unit provider whose identity is available via
         the properties on the Logical Unit object.


     Logical Unit Number

         A Logical Unit Number is the SCSI identifier of a  logi-
         cal unit within a target.


     Target Port

         A Target port object is provided to the SCSI Target Mode

         Framework for the purposes of receiving SCSI commands on
         a particular logical unit. Library clients can manage  a
         Logical Unit object's availability to one or more Target
         port objects. Library clients cannot add or remove  Tar-
         get  objects  from  the system. Every Target port object
         within the SCSI Target Mode  Framework  is  owned  by  a
         Local  Port provider whose identity is available via the
         properties on the Target port object.


     Target Port Group

         A Target Port Group is a set of one or more Target ports
         that  are combined together for the purposes of applying
         availability to a Logical Unit  object.  A  Target  Port
         Group  may  be  applied  to any given Logical Unit via a
         view entry. Target ports may not be  a  member  in  more
         than  one Target Port Group. Target Port Group names are
         unique within the framework.


     View

         A View is a list of logical units exposed to a  list  of
         initiator ports through a list of targets.


     View Entry

         A View Entry object defines the association of  an  host
         group,  a  target group and a logical unit number with a
         specified logical unit. When a view entry is created for
         a  logical  unit, a caller can assign all targets and/or
         all initiator ports to the logical unit thus making  the
         logical  unit  accessible to all target ports and/or all
         initiator ports. A logical unit may  have  one  or  more
         view  entries  associated  with it. Any two view entries
         are considered to be in conflict when an attempt is made
         to  duplicate  the  association  of  any given initiator
         port, target port and logical unit. Attempting this will
         result   in   an   error   returned  from  the  call  to
         stmfAddViewEntry(3STMF).
