changers - list SCSI autochangers attached to the system


       changers [ -dv ] [ -a b.t.l ] [ -l ]


       The  changers  program  lists  all of the SCSI autochangers (jukeboxes)
       connected to the current system.


       -a b.t.l
              Selects a specific ordinal SCSI address, where b is the  logical
              SCSI  bus,  t is the SCSI target, and l is the SCSI logical unit
              number (LUN) on that target. See libscsi(1).

       -d     Determines the names and addresses of  the  autochanger's  media
              elements (for example, tape drives).

       -l     Performs a complete LUN search for all SCSI adapters in the sys-
              tem.  This argument is accepted on all  systems,  but  does  not
              have  any  effect  on  HP-UX systems.  Due to the method used to
              scan for available devices  on  HP-UX  systems,  all  accessible
              devices  are  always  shown, and the -l option has no additional
              effect.  On all other platforms, the normal behavior is to start
              checking  at  LUN 0 for SCSI devices.  The first empty LUN found
              will end the search for a given target ID.  With the -l  option,
              all  LUN  present  on  all target IDs for all SCSI busses in the
              system will be checked for devices.  This can take a  very  long
              time  and  should  therefore  only  be used when necessary.  For
              example, a Fibre Channel adapter can  support  126  target  IDs,
              each  of  which  may have 80 or more LUNs.  Checking all LUNs on
              this single adapter may take over 10 minutes.

       -v     Lists more detailed  information  about  each  autochanger.  The
              details  indicate  how  many  media transports (MT, for example,
              robot  arm),  storage  transports  (ST,  for   example,   slot),
              import/export  elements  (IE,  for example, mail slot), and data
              transport (DT) elements the autochanger contains. The -v  option
              also provides information about the element movement matrix sup-
              ported by the autochanger.


       Sample output is shown below: hal$ changers -dv -a 0.2.0
       scsidev@0.2.0:Vendor <SPECTRA>, Product <4000>
        Data Transfer Element at address 80 is scsidev@0.5.0
               Device:Vendor <HP>, Product <C1533A>
          System Name: /dev/rmt2.1
        Data Transfer Element at address 81 is scsidev@0.6.0
               Device:Vendor <HP>, Product <C1533A>
          System Name: /dev/rmt3.1
                         ->DT,  ->IE,  ->ST,  ->MT
