NAME
       sg_read_block_limits - send SCSI READ BLOCK LIMITS command


SYNOPSIS
       sg_read_block_limits [--help] [--hex] [--raw]  [--readonly] [--verbose] [--version] DEVICE


DESCRIPTION
       Send  a  SCSI  READ  BLOCK LIMITS command to DEVICE and outputs the response. This command is defined for
       tape (drives) and its description is found in the SSC documents at http://www.t10.org .


OPTIONS
       Arguments to long options are mandatory for short options as well.

       -h, --help
              output the usage message then exit.

       -H, --hex
              output response in hex (rather than decode it).

       -r, --raw
              output response in binary to stdout.

       -R, --readonly
              open DEVICE in read-only mode. The default is to open it in read-write mode.

       -v, --verbose
              increase the level of verbosity, (i.e. debug output).

       -V, --version
              print the version string and then exit.


EXIT STATUS
       The exit status of sg_read_block_limits is 0 when it is successful. Otherwise see  the  sg3_utils(8)  man
       page.


EXAMPLES
       It  is usually okay to use no options. Here is an invocation (on the first line following the "#" command
       prompt) followed by some typical output:

          # sg_read_block_limits /dev/st0
       Read Block Limits results:
               Minimum block size: 1 byte(s)
               Maximum block size: 16777215 byte(s), 16383 KB, 15 MB
