NAME

       sg_read_block_limits - send SCSI READ BLOCK LIMITS command

SYNOPSIS

       sg_read_block_limits [--help] [--hex] [--raw] [--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.

       -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

NAME

       sg_referrals - send SCSI REPORT REFERRALS command

SYNOPSIS

       sg_referrals [--help] [--hex] [--lba=LBA] [--maxlen=LEN] [--one-segment] [--raw] [--verbose] [--version] DEVICE

DESCRIPTION

       Send the SCSI REPORT REFERRALS command to the DEVICE and outputs the response. This command was introduced in (draft) SBC-3 revision 24 and
       devices that support referrals should support this command.

       The default action is to decode the response for all user data segment referral descriptors. The amount of output can  be  reduced  by  the
       --lba and --one-segment options.

OPTIONS

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

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

       -H, --hex
	      output response to this command in ASCII hex.

       -l, --lba=LBA
	      where  LBA  is  the Logical Block Address (LBA) in the first user data segment the DEVICE should report the referrals parameter data
	      for.

       -m, --maxlen=LEN
	      where LEN is the (maximum) response length in bytes. It is placed in the cdb's "allocation length" field. If not given then  256	is
	      used. 256 is enough space for the response header and user data segment descriptors.

       -s, --one-segment
	      report the user data segment of the segment spefified by the LBA parameter only.

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

       -v, --verbose
	      increase the level of verbosity, (i.e. debug output). Additional output caused by this option is sent to stderr.

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

NOTES

       For a discussion of referrals see section 4.25 of sbc3r25.pdf at http://www.t10.org (or the corresponding section of a later draft).

EXIT STATUS

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