sg_luns − send the SCSI REPORT LUNS command
sg_luns [−−decode] [−−help] [−−hex] [−−quiet] [−−raw] [−−select=SR] [−−verbose] [−−version] DEVICE
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.
−d, −−decode
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.
−h, −−help
output the usage message then exit.
−H, −−hex
output response to this command in ASCII hex.
−q, −−quiet
output ASCII hex rendering of each report lun, one per line.
−r, −−raw
output response in binary (to stdout).
−s, −−select=SR
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)).
−v, −−verbose
increase the level of verbosity, (i.e. debug output).
−V, −−version
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.
