| .PP |
| 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. |
| .TP |
| --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. |
| .TP |
| --help | -h |
| output the usage message then exit. |
| .TP |
| --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. |
| .TP |
| --verbose | -v |
| increase the level of verbosity, (i.e. debug output). |
| .TP |
| --version | -V |
| print the version string and then exit. |
