       sg_get_lba_status - send the SCSI GET LBA STATUS command


       sg_get_lba_status [--brief] [--help] [--hex] [--lba=LBA] [--maxlen=LEN]
       [--raw] [--verbose] [--version] DEVICE


       Send the SCSI GET LBA STATUS command to  the  DEVICE  and  outputs  the
       response.  This command was introduced in (draft) SBC-3 revision 20 and
       devices that support thin provisioning should support this command.

       The default action is to  decode  the  response  into  one  LBA  status
       descriptor  per  line output 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 in decimal. The provisioning status
       can be in the range 0 to 15 of which only 0 (mapped), 1 (unmapped)  and
       2 (anchored) are used currently. The amount of output can be reduced by
       the --brief option.


       Arguments to long options are mandatory for short options as well.

       -b, --brief
              when use once then one LBA status descriptor per line is  output
              to  stdout.   Each  line  has  this  format: "0x<descriptor_LBA>
              0x<blocks> <provisioning_status>". So  the  descriptor  LBA  and
              blocks are output in hex and the provisioning status in decimal.
              When used twice  (e.g.  ’-bb’  or  ’--brief  --brief’)  the  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 on 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.

       -h, --help
              output the usage message then exit.

       -H, --hex
              output response to this command in ASCII hex.

       -l, --lba=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 provisioning status

       -m, --maxlen=LEN
              where LEN is the (maximum)  response  length  in  bytes.  It  is
              placed in the cdb’s "allocation length" field. If not given then
              24 is used. 24 is enough space for the response 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).

       -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.


       For  a  discussion of thin provisioning see section 4.6.3 of sbcr22.pdf
       at (or the corresponding section of a later  draft).


       The  exit  status  of  sg_get_lba_status  is  0  when it is successful.
       Otherwise see the sg3_utils(8) man page.
