There is some understandable confusion about which driver to use for SCSI
attached
devices.  ADSM relies on the Atape driver for the Magstar family of tapes and
libraries (on AIX), but it relies on the device driver shipped with ADSM for
all others
(DLT, 8mm, 4mm, QIC, optical drives, STK drives- did I miss any?)   The
confusion is
that when the new 7331 library is purchased, it comes with a driver (Atape on
AIX,
IBMtape on Solaris) for the robot to go with the generic OST driver for the
drive.
That's to support non-ADSM applications, but ADSM has its own driver for these
devices.

So to configure your 7331/7337, use Smit/Devices/ADSM Devices.   Select the
library and drive options from that panel, and the device special files that
you get are
/dev/mtX and /dev/lbX (X == some number from 0 to whatever).

On AIX, do NOT use /dev/rmtX.smc or /dev/smcX for the library robot.  (Nor
/dev/rmtX
for 8mm or DLT drives.)   However, those are the files you would use for 3570,
3575, 3590,
and 3490.

On Solaris, the story is the same except that instead of Atape, it's known as
IBMtape, and
the special files look slightly different.   For ADSM devices , they are
/dev/rmt/Xmt (drives) or /dev/rmt/Xlb (library).  For Magstar devices, they're
/dev/rmt/Xst (drives) or /dev/rmt/Xsmc (library).
