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.
