NAME

       sg_referrals - send SCSI REPORT REFERRALS command

SYNOPSIS

       sg_referrals [--help] [--hex] [--lba=LBA] [--maxlen=LEN] [--one-segment] [--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.

NOTES

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