     23Look at tape management:

     25"Bill R. Williams" <brw_at_etsu.edu>
     26--------------------------------------------------------------------
     27FWIW:  I seen problems with other platform/backup-software wherein the
     28backup was to tape and verify was attempted.  (I won't mention names.  :-)
     29
     30ANYWAY, my rule of thumb regarding use of tape devices is :
     31        mt -f $TAPE status
     32                I can check $? to see if it at least can "see" the
     33                device.
     34        mt -f $TAPE rewind
     35                I can check $? to see if it can operate the device,
     36                and this will cause a "wait" until the device is
     37                ready.
     38This also always assures me that my $TAPE is at the beginning.
     39For those of ye saying, "Well, duh!"
     40Let me just say: NEVER presume that your tape is at the beginning!
     41There are devices which allow use of TAPE with NO-REWIND-ON
     42open/close.
     43Other *opinions* of note:
     44*       I always set my tape device to blocksize=0 which means
     45        variable-blocks.
     46*       I always write the biggest blocksize to tape that I can.  The
     47        bigger the tape block and the faster the read/writes plus the
     48        more efficient use of the physical media.  IOW: You get more
     49        data on the tape with bigger blocks.
     50Of couse these come from the "old school" and have served me well even
     51up through the new LTO devices.
     52(Yes, I have seen open-spool tape run off the end of the reel. Go
     53ahead and laugh.  ...was never funny at the time.  :-)
