UNMAP not supported

bad argument to '--lba'

anchor grpnum help lba timeout verbose version value for '--grpnum=' must be 0 to 31
Usage: sg_unmap [--anchor] [--grpnum=GN] [--help] [--in=FILE]
[--lba=LBA,LBA...] [--num=NUM,NUM...] [--timeout=TO]
[--verbose] [--version] DEVICE
where:
--anchor|-a set anchor field in cdb
--grpnum=GN|-g GN GN is group number field (def: 0)
--help|-h print out usage message
--in=FILE|-I FILE read LBA, NUM pairs from FILE (if FILE is '-'
then stdin is read)
--lba=LBA,LBA...|-l LBA,LBA... LBA is the logical block address
to start NUM unmaps
--num=NUM,NUM...|-n NUM,NUM... NUM is number of logical blocks to
unmap starting at corresponding LBA
--timeout=TO|-t TO command timeout (unit: seconds) (def: 60)
--verbose|-v increase verbosity
--version|-V print version string and exit
Perform a SCSI UNMAP command. LBA, NUM and the values in FILE are assumed
to be decimal. Use '0x' prefix or 'h' suffix for hex values.
Example to unmap LBA 0x12345:
sg_unmap --lba=0x12345 --num=1 /dev/sdb
unrecognised option code 0x%x ??
Unexpected extra argument: %s
expect '--in=' by itself, or both '--lba=' and '--num='
since '--lba=' is given, also need '--num='
expect either both '--lba=' and '--num=', or '--in=' by itself
'--lba' cannot be read from stdin
build_lba_arr: error at pos %d
'--len' cannot be read from stdin
build_num_arr: error at pos %d
need same number of arguments to '--lba=' and '--num=' options

build_joint_arr: array length exceeded
build_joint_arr: error in line %d, at pos %d
build_joint_arr: expect LBA,NUM pairs but decoded odd number

no addresses found in '--in=' argument, file: %s
UNMAP failed, device not ready
