sg_luns - send the scsi command report luns

sg_luns [--decode] [--help] [--select=<n>] [--verbose] [--version] <scsi_device>

Send REPORT LUNS command to a Linux SCSI device and output the response. In the recent SCSI draft standard SPC-3 device support for this command is mandatory.

--decode | -d

decode logical unit numbers into their hierarchical parts. Interprets luns as described in SAM-3 (rev 14) when the HiSup bit is set in a standard INQUIRY's response.

--help | -h

output the usage message then exit.

--select=<n> | -s <n>

this option sets the 'select report' field in the SCSI REPORT LUNS command. The default value is 0. When 0 is given (or this option is not specified) then the given 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 given device should yield a list of only "well known" logical units addressable via this "I_T" nexus. When 2 is given the given device should yield all luns addressable via this "I_T" nexus. Currently SPC-3 (rev 21) doesn't specify any other values.

--verbose | -v

increase the level of verbosity, (i.e. debug output).

--version | -V

print the version string and then exit.
