NAME

sg_referrals - send the 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).
