SG_REFERRALS(8)			   SG3_UTILS		       SG_REFERRALS(8)

NAME
       sg_referrals - send SCSI	REPORT REFERRALS command

SYNOPSIS
       sg_referrals  [--help]  [--hex]	[--lba=LBA] [--maxlen=LEN] [--one-seg-
       ment] [--raw] [--readonly] [--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 specified by the LBA
	      parameter	only.

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

       -R, --readonly
	      open the DEVICE read-only	(e.g. in Unix with the O_RDONLY	flag).
	      The default is to	open it	read-write.

       -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.

       For a discussion	of  referrals  see  section  4.25  of  sbc3r25.pdf  at

       The  exit  status of sg_referrals is 0 when it is successful. Otherwise
