Send the SCSI REPORT LUNS command to the DEVICE and outputs the
response. In the SPC-3 SCSI standard support for this command is mandatory.
Arguments to long options are mandatory for short options as well.
decode logical unit numbers into their hierarchical parts. Interprets
luns as described in SAM-3 when the HiSup bit is set in a
standard INQUIRY's response.
output the usage message then exit.
output response to this command in ASCII hex.
where LEN is the (maximum) response length in bytes. It is placed in
the cdb's "allocation length" field. If not given (or LEN is zero)
then 8192 is used. The maximum allowed value of LEN is 65536.
output ASCII hex rendering of each report lun, one per line.
output response in binary (to stdout).
this option sets the 'select report' field (SR) in the SCSI REPORT
LUNS command. The default value is 0. When 0 is given (or this option is
not specified) then the DEVICE should yield a list of luns addressable
via this "I_T nexus" that use the following lun addressing methods: logical
unit addressing, peripheral device addressing and flat space addressing.
When 1 is given the DEVICE should yield a list of only "well known"
logical units addressable via this "I_T" nexus. When 2 is given the
DEVICE should yield all luns addressable via this "I_T" nexus.
To simplify, for the I_T nexus associated with the DEVICE, the
meanings of the SR values are:
0 : all luns excluding well known logical units
1 : well known logical units
2 : all luns
Values greater than 2 are reserved (at SPC-4 (rev 8)).
increase the level of verbosity, (i.e. debug output).
print the version string and then exit.
The exit status of sg_luns is 0 when it is successful. Otherwise see
the sg3_utils(8) man page.
