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 spefified 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.

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.
