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 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.
