       The ssjjiirreelleemm program tests the  SJIRELEM  command  on  SJI
       compliant  Jukeboxes  (see lliibbssjjii(8)).  This command reads
       media presence and origin data from a Jukebox.

       Typical output for this command might look like:

       Element Data for 0.2.1, Element Type DATA TRANSPORT:
               Elem[001]: pres_val=1 med_pres=1 med_side=0
                          Origin: type STORAGE, address 5
       Element Data for 0.2.1, Element Type STORAGE:
               Elem[001]: pres_val=1 med_pres=1 med_side=0
               Elem[002]: pres_val=1 med_pres=1 med_side=0
               Elem[003]: pres_val=1 med_pres=1 med_side=0
               Elem[004]: pres_val=1 med_pres=1 med_side=0
               Elem[005]: pres_val=1 med_pres=0 med_side=0
               Elem[006]: pres_val=1 med_pres=1 med_side=0
               Elem[007]: pres_val=1 med_pres=1 med_side=0
       Element Data for 0.2.1, Element Type MEDIA TRANSPORT:
               Elem[001]: pres_val=1 med_pres=0 med_side=0

       The _d_e_v_n_a_m_e argument should be any device name that can be
       used  to  reach a SJI compliant Jukebox driven by the sys-
       tem. Typical usage is in constructing the name  that  con-
       tains the SCSI Bus, the SCSI Target ID and the SCSI Lun on
       that target, e.g., _s_c_s_i_d_e_v_@_0_._4_._0.

       The output is sorted  by  types  available,  and  then  by
       ascending order.

       The  boolean  token  mmeedd__pprreess  states  whether the Jukebox
       believes that there is media present at this location.

       The boolean token pprreess__vvaall  is  a  subtle  and  overloaded
       indicator that states (if set to true, or 1), that the the
       token mmeedd__pprreess should be believed absolutely. If  pprreess__vvaall
       is  not  true  (i.e.,  set  to zero), and pprreess__vvaall is true
       (i.e., set to one), it is probable that there _i_s media  at
       that location, but that there is some exception associated
       with it. This may mean (in some cases and for  some  Juke-
       boxes)  that a tape has a missing, upside down, or unread-
       able bar code label. It may also mean, hoever, in the case
       of  media  located  inside  a DATA TRANSPORT element (tape
       drive) that the Jukebox cannot really tell,  but  that  as
       far as it knew, there _w_a_s media there at some point in the
       past (say, prior  to  a  power  failure).   If  the  token
       pprreess__vvaall  is not true (i.e., set to zero), and pprreess__vvaall is
       also not true (i.e., set to zero),  it  is  pretty  likely

       that  there isn't media in that location.  Typically, most
       of this uncertainty gets eliminated the next time an  INI-
       TIALIZE ELEMENT STATUS is done (see ssjjiiiieellmm(8)).

       The  token  mmeedd__ssiizzee is for two sided media (e.g., optical
       disks), where the Jukebox has kept track of which side  is
       up.

       When  the  Jukebox  can,  it might also say where the last
       place a piece of media had been prior to its current loca-
       tion, in which case _s_j_i_r_e_l_e_m will print that out.
