\fB\-L\fR, \fB\-\-lba\fR=\fILBA\fR
59
the number \fILBA\fR is placed in the "lba" field of the ATA SET
60
FEATURES command. Only some sub\-commands (a term used for the value
61
placed in the "feature" field) require the lba field to be set. This
62
value is typically not a "logical block address" as the acronym might
63
imply. The default value placed in the "lba" field is 0. The maximum value
64
allowed for \fILBA\fR is 0xfffffffe (or 0xffffff if \fI\-\-len=\fR12).

67
this is the length of the SCSI cdb used for the ATA PASS\-THROUGH commands.
60
68
The argument can either be 16 or 12. The default is 16. Some SCSI
61
69
transports cannot convey SCSI commands longer than 12 bytes.

\fB\-L\fR, \fB\-\-lba\fR=\fILBA\fR
64
the number \fILBA\fR is placed in the "lba" field in the ATA SET
65
FEATURES command. Only some subcommands (a term used for the value
66
placed in the "feature" field) require the lba field to be set.
67
This value is not a "logical block address" as the acronym might imply.

In the 2.4 series of Linux kernels the \fIDEVICE\fR must be
77
a SCSI generic (sg) device. In the 2.6 series block devices (e.g. disks
78
a SCSI generic (sg) device. In the 2.6 and 3 series block devices (e.g. disks
78
79
and ATAPI DVDs) can also be specified. For example "sg_inq /dev/sda"
79
80
will work in the 2.6 series kernels. From lk 2.6.6 other SCSI "char"
80
81
device names may be used as well (e.g. "/dev/st0m"). Prior to lk 2.6.29

The exit status of sg_sat_set_features is 0 when it is successful. Otherwise
