NAME

       sg_referrals - send the 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.

NAME

       sg_read_buffer - send a SCSI READ BUFFER command

SYNOPSIS

       sg_read_buffer [--help] [--hex] [--id=ID] [--length=LEN] [--mode=MO] [--offset=OFF] [--raw] [--verbose] [--version] DEVICE

DESCRIPTION

       Sends  a  SCSI  READ  BUFFER  command  to the DEVICE, and if there is a response either decodes it, prints it in hexadecimal or sends it in
       binary to stdout. If a response is received for a "descriptor" mode then, in the absence of --hex and --raw, it is  decoded.  Response  for
       non-descriptor modes are output in hexadecimal unless the --raw option is given.

OPTIONS

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

       -h, --help
	      output the usage message then exit. If used multiple times also prints the mode names and their acronyms.

       -H, --hex
	      output the response in hexadecimal. When given twice the response is output in hex with the corresponding representation in ASCII to
	      the right of each line.

       -i, --id=ID
	      this option sets the buffer id field in the cdb. ID is a value between 0 (default) and 255 inclusive.

       -l, --length=LEN
	      where LEN is the length, in bytes, that is placed in the "allocation length" field in the cdb. The default value is 4  (bytes).  The
	      device may respond with less bytes.

       -m, --mode=MO
	      this option sets the mode field in the cdb. MO is a value between 0 (default) and 31 inclusive. Alternatively an abbreviation can be
	      given.  To list the available mode abbreviations use an invalid one (e.g. '--mode=xxx'). As an example, to  fetch  the  read  buffer
	      descriptor give '--mode=desc' .

       -o, --offset=OFF
	      this option sets the buffer offset field in the cdb. OFF is a value between 0 (default) and 2**24-1 . It is a byte offset.

       -r, --raw
	      if a response is received then it is sent in binary to stdout.

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

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

NOTES

       All  numbers  given  with options are assumed to be decimal.  Alternatively numerical values can be given in hexadecimal preceded by either
       "0x" or "0X" (or has a trailing "h" or "H").

EXIT STATUS

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