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 de‐
       fined  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.

              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
