NAME

       sg_luns - send the SCSI REPORT LUNS command

SYNOPSIS

       sg_luns [--decode] [--help] [--hex] [--maxlen=LEN] [--quiet] [--raw] [--select=SR] [--verbose] [--version] DEVICE

DESCRIPTION

       Send the SCSI REPORT LUNS command to the DEVICE and outputs the response. In the SPC-3 SCSI standard support for this command is mandatory.

OPTIONS

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

       -d, --decode
	      decode  logical  unit  numbers  into  their hierarchical parts. Interprets luns as described in SAM-3 when the HiSup bit is set in a
	      standard INQUIRY's response.

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

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

       -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  (or  LEN	is
	      zero) then 8192 is used. The maximum allowed value of LEN is 65536.

       -q, --quiet
	      output ASCII hex rendering of each report lun, one per line.

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

       -s, --select=SR
	      this  option  sets  the 'select report' field (SR) in the SCSI REPORT LUNS command. The default value is 0. When 0 is given (or this
	      option is not specified) then the DEVICE should yield a list of luns addressable via this "I_T nexus" that  use  the  following  lun
	      addressing  methods:  logical  unit  addressing, peripheral device addressing and flat space addressing.	When 1 is given the DEVICE
	      should yield a list of only "well known" logical units addressable via this "I_T" nexus. When 2 is given the DEVICE should yield all
	      luns  addressable  via  this  "I_T" nexus.  To simplify, for the I_T nexus associated with the DEVICE, the meanings of the SR values
	      are:
		0 : all luns excluding well known logical units
		1 : well known logical units
		2 : all luns
	      Values between 0xf8 and 0xff (inclusive) are vendor specific (SPC-4 (rev 32), other values greater than 2 are reserved.

       -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_luns is 0 when it is successful. Otherwise see the sg3_utils(8) man page.

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.
