The 16 byte command variant was introduced in (draft) SBC-3 revision 20 and devices that support logical block provisioning should support this command. The GET LBA [STATUS(32)](https://www.chedong.com/phpMan.php/man/STATUS/32/markdown) command was added in (draft) SBC-4 revision 14. The default action is to decode the response into one LBA status descriptor per line then output a header and the status descriptors to stdout. The descriptor LBA is output in hex (prefixed by '0x') and the number of blocks is output in decimal followed by the provisioning status and additional status in decimal. The provisioning status can be in the range 0 to 15 of which only 0 (mapped or unknown), 1 (unmapped), 2 (anchored), 3 (mapped) and 4 (unknown) are used currently. The amount of output can be reduced by the _--brief_ option. Rather than send this SCSI command to _DEVICE_, if the _--inhex=FN_ option is given, then the contents of the file named _FN_ are decoded as ASCII hex and then processed if it was the re‐ sponse of this command. ## OPTIONS Arguments to long options are mandatory for short options as well. ### -S --16 send SCSI GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command which is the 16 byte variant. In the absence of the _--16_ or the _--32_ options the SCSI GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command is sent. If both _--16_ and the _--32_ options are given then the GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command is sent. ### -T --32 send SCSI GET LBA [STATUS(32)](https://www.chedong.com/phpMan.php/man/STATUS/32/markdown) command which is the 32 byte variant. When given together with the _--16_ option then this option is ignored (so the GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command is sent). ### -b --brief when use once then one LBA status descriptor per line is output to stdout. Each line has this format: "0x 0x ". So the descriptor's starting LBA and number of blocks are output in hex while the provisioning status and additional status are in decimal. When used twice (e.g. '-bb' or '--brief --brief') then the provisioning status of the given _LBA_ (or LBA 0 if the _--lba_ option is not given) is output to stdout. A check is made that the given _LBA_ lies in the range of the first returned LBA status descriptor (as it should according to SBC-3 revision 20) and warnings are sent to stderr if it doesn't. ### -e --element-id where _EI_ is the element identifier of the physical element for which the LBAs shall be reported based on the value in the report type field (i.e. _RT_). This option is only active with the SCSI GET LBA [STATUS(32)](https://www.chedong.com/phpMan.php/man/STATUS/32/markdown) command (i.e. it is ignored if the GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command is sent). Valid element identifiers are non-zero. The default value of _EI_ is 0 which means in the context that no element identifier is specified. ### -h --help output the usage message then exit. ### -H --hex output response to this command in ASCII hex. ### -i --inhex where _FN_ is a filename whose contents are assumed to be ASCII hexadecimal bytes. See the "FORMAT OF FILES CONTAINING ASCII HEX" section in the sg3_utils manpage for more information. If _DEVICE_ is also given then it is ignored. If the _--raw_ option is also given then the contents of _FN_ are treated as binary. ### -l --lba where _LBA_ is the starting Logical Block Address (LBA) to check the provisioning status for. Note that the _DEVICE_ chooses how many following blocks that it will return provi‐ sioning status for. ### -m --maxlen where _LEN_ is the (maximum) response length in bytes. It is placed in the cdb's "allo‐ cation length" field. If not given then 24 is used. 24 is enough space for the re‐ sponse header and one LBA status descriptor. _LEN_ should be 8 plus a multiple of 16 (e.g. 24, 40, and 56 are suitable). ### -r --raw output response in binary (to stdout) unless the _--inhex=FN_ option is also given. In that case the input file name (_FN_) is decoded as binary (and the output is _not_ in binary). ### -R --readonly open the _DEVICE_ read-only (e.g. in Unix with the O_RDONLY flag). The default is to open it read-write. ### -t --report-type where _RT_ is 0 for report all LBAs; 1 for report LBAs using non-zero provisioning sta‐ tus; 2 for report LBAs that are mapped; 3 for report LBAs that are de-allocated; 4 for report LBAs that are anchored; 16 for report LBAs that may return an unrecovered er‐ ror. The REPORT TYPE field was added to the GET LBA STATUS cdb in sbc4r12. Since the REPORT TYPE field is newer than the command, the response contains the RTP bit to indicate whether or not the _DEVICE_ acts on the REPORT TYE field (set when it does act on it, clear otherwise). ### -s --scan-len where _SL_ is the scan length which is the maximum number of contiguous logical blocks to be scanned for logical blocks that meet the given report type (i.e. _RT_). This op‐ tion is only active with the SCSI GET LBA [STATUS(32)](https://www.chedong.com/phpMan.php/man/STATUS/32/markdown) command (i.e. it is ignored if the GET LBA [STATUS(16)](https://www.chedong.com/phpMan.php/man/STATUS/16/markdown) command is sent). The default value of _SL_ is 0 which should be interpreted by the _DEVICE_ as there is no limits to the number of LBAs that shall be scanned. ### -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. ## NOTES In SBC-3 revision 25 the calculation associated with the Parameter Data Length field in the response was modified. Prior to that the byte offset was 8 and in revision 25 it was changed to 4. For a discussion of logical block provisioning see section 4.7 of sbc4r14.pdf at (or the corresponding section of a later draft). ## EXIT STATUS The exit status of sg_get_lba_status is 0 when it is successful. Otherwise see the [sg3_utils(8)](https://www.chedong.com/phpMan.php/man/sg3utils/8/markdown) man page. ## AUTHORS Written by Douglas Gilbert. ## REPORTING BUGS Report bugs to . ## COPYRIGHT Copyright © 2009-2019 Douglas Gilbert This software is distributed under a FreeBSD license.
