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.
