sg_referrals: send SCSI REPORT REFERRALS command
NAMEsg_referrals - send SCSI REPORT REFERRALS command
SYNOPSISsg_referrals [--help] [--hex] [--lba=LBA] [--maxlen=LEN] [--one-segment] [--raw] [--verbose] [--version] DEVICE
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.
OPTIONSArguments 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.
NOTESFor 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 STATUSThe exit status of sg_referrals is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
