NAME

       cdi_block_limits - query block size limits on a tape device

SYNOPSIS

       cdi_block_limits -f device [ -v ] [ -t { s | t | g | n | m | i } ]

DESCRIPTION

       The  cdi_block_limits  program  queries  block  size  limits  on a tape
       device.  The cdi_block_limits program returns the block size limits for
       the named SCSI device (with the -f option).  Note that a device's block
       size limits may be larger than the  operating  system's  limits.   This
       program specifically returns the device's block size limits.

OPERANDS

       -f     device
            Specifies the device to obtain block size information from.

OPTIONS

       -t     Use the -t option to specify the method of tape functions to use
              to query block size limits.  If the -t option is not  specified,
              the default method is to use the OS tape driver SCSI passthrough
              functions.  Please refer to the libcdi (8) manpage  for  a  com-
              plete   list  of  access  methods  currently  supported  by  the
              cdi_block_limits program.

       -v     Run the program in verbose mode.  This option will print out the
              version number of the CDI library used by the program.

EXAMPLES

       Sample output including drive status information:

     % cdi_block_limits -f /dev/rmt/2cbn

     Block size limits returned from   accessed through /dev/rmt/2cbn
                    maximum block size allowed is 16776128
                    minimum block size allowed is 61301
          cdi_info.drivestat is:
            status = 1, DRIVE_STATUS_NO_ERROR
            msg = Drive reports no error - but state is unknown
