The third parameter is defined as follows:
In the
"TLZ9-data"
-- The first parameter (1) is the revision level of the software and is set to 1.
-- The second parameter (0x34) is the tape type, specifying "other" tape drive. (This
is defined in /usr/include/sys/mtio.h.)
-- The third parameter (0) is the block size in bytes (see note at beginning of this
section).
-- The fourth parameter (0x1639) defines the options selected. The 0x1639 value
represents the following options:
ST_VARIABLE
ST_BSF
ST_BSR
ST_LONG_ERASE
ST_KNOWS_EOD
ST_UNLOADABLE
ST_LONG TIMEOUTS
-- The fifth parameter (4) defines the number of densities. The maximum definable
number of densities is 4
-- The sixth through ninth parameters (0xfd, 0xfd, 0xfe, 0xfe) comprise the density
codes (low _ hi) as defined below:
•
0xfd is the vendor-unique density code for the 120-m DDS2 tape in the
uncompressed mode (4.0 GB).
•
0xfe is the vendor-unique density code for the 120-m DDS2 tape in the
compressed mode (8.0 GB).
-- The last parameter in the data string is the default density of 3 for the 120-m DDS2
tape in the compressed mode.

This maximum definable number of densities is a Sun Operating System limitation.
