800.0. "OSMS and LUN's for RW557?" by KERNEL::CLARK (STRUGGLING AGAINST GRAVITY...) Wed Mar 05 1997 12:12

    Does OSMS (early, 3.4 or future) support the use of LUN's for RW557 in
    LUN 1 or 2 mode?

800.1Yes, for OSMS V3.4 for VMSTAPE::SENEKERHead banging causes brain mushWed Mar 05 1997 12:3218
    OSMS has supported the use of SCSI addresses with non-zero logical unit
    number for a long time.  The RW557 was not supported by the OSMS software
    until V3.4.  OSMS V3.4 support allows the RW557 to be used in "address"
    or "lun" mode.
    
    FYI:  The RW555, RW552, and RW551 jukeboxes also have LUN mode as an
    	  option and OSMS V3.4 allows the same "address" or "lun" mode
    	  usage for these jukeboxes as well.
    
    The change that OSMS V3.4 had, as compared to earlier releases, was
    that it's installation command procedure changed to "try" to make
    the configuration (and building of startup command files) easier.
    
    The earlier releases of OSMS allowed you to configure devices using
    SCSI addresses that contained a non-zero logical unit number but the
    questions asked were much different.

800.2Thanks...More information?KERNEL::CLARKSTRUGGLING AGAINST GRAVITY...Thu Mar 06 1997 04:5017
    Rob...
    	Thanks for the reply.
    
    	Although I have attempted to configure a LUN situation
    (RV65/SONY-WDA610) I have not had too much success in making it work
    reliably. I tried version 3.2, 3.3, and 3.3-1, all on VAX 6.1.
    
    	I had drawn the (mistaken) conclusion that this, combined with the
    lack of discussion, and the very brief topic in the user or install
    manuals for OSMS suggested that it was a hangover from Laserstar, and
    no longer supported.
    
    	Is there more information available on configuring LUN's than
    appears in the quoted manuals? I'd be grateful for a pointer.

800.3vendor unique use of SCSITAPE::SENEKERHead banging causes brain mushThu Mar 06 1997 09:4112
    Dave,
    
    As part of OSMS/LaserStar documentation there is nothing more on
    LUN's.  Part of your problem may be caused by the way the SONY-WDA610
    does it's addressing internal to the jukebox.  Sony choose to
    implement a "vendor unique" way to use the SCSI protocol to control
    the jukebox.
    
    If needed why don't you continue an old or start a new notes stream
    asking questions about setup of the RV65/SONY-WDA610.

800.4RV65 Identity crisis causes much embarrasment!KERNEL::CLARKSTRUGGLING AGAINST GRAVITY...Thu Mar 06 1997 12:3526
    re: -1.
    
    <<<Sony choose to implement a "vendor unique" way to use the SCSI
    	protocol to control the jukebox.>>>
    
    	You 'aint kiddin'!!! I tried all combinations of SCSI ID and LUN's
    together with 3.2, 3.3, and 3.3-1 to try to get some sort of
    functionality to work.
    
    	I ended up being able to manipulate JBA0, but no other device.
    
    	Although the Juke is supposed to present itself as a humungeous
    single optical drive (I think!) OSMS still seems to configure multiple
    JBA devices. The fact that only JBA0 seems to respond makes me suspect
    that it's behaving as a single big drive, but that OSMS still thinks
    it's addressing lots of platters.
    
    <<<If needed why don't you continue an old or start a new notes stream
        asking questions about setup of the RV65/SONY-WDA610.>>>
    
    	Well I was kind of embarrased...I mean who plays with
    RV65's/WDA610's these days?...But I'll swallow my embarrasment and do
    just that!
