C–5
where:
In the “tape-config-list” parameter:
•
The first parameter (
DEC TZ87
) is the parameter returned by the SWXTL
SBB on a SCSI inquiry command. (There should be five spaces between “
DEC
”
and “
TZ87
” elements.)
•
The second parameter (
DEC 10GB Cart. DLT Streaming /w
compression
) is a nickname for the SWXTL drive.
•
The third parameter is defined as follows:
In the “TZ87-data” string:
–
The first parameter (1) is the revision level of the software and is set to 1. The
first parameter (1) is the revision level of the software and is set to 1.
–
The second parameter (
0x36
) is the tape type, specifying “other” tape drive.
(This is defined
in
/usr/include/sys/mtio.h.
)
–
The third parameter (
8192
) is the block size in bytes.
–
The fourth parameter (
0x1639
) defines the options selected. The 0x1639
value represents the following options:
ST_VARIABLE
= 0x0001
ST_BSF
= 0x0008
ST_BSR
= 0x0010
ST_LONG_ERASE
= 0x0020
ST_KNOWS_EOD
= 0x0200
ST_UNLOADABLE
= 0x0400
ST_LONG TIMEOUTS = 0x1000
–
The fifth parameter (
4
) defines the number of densities. The maximum
definable number of densities is 4.*
–
The sixth parameter (
0x17
) is the vendor-unique density code for the TK85
(2.6 GB).
–
The seventh parameter (
0x18
) is the vendor-unique density code for TK86
(6.0 GB).
–
The eighth parameter (
0x80
) is the vendor-unique density code for the TK87
native (10 GB).
–
The ninth parameter (
0x81
) is the default density code for the TK87
compressed mode.
–
The last parameter in the SWXTL-data parameter is the default density
3
,
TK87 in the compressed mode.
_______________
*This maximum definable number of densities is a Sun Operating System limitation.
