C.2.3.2 System Modification
Perform the following steps to modify the system to communicate with the
autoloader (see notes at the end of this sub-section for TLZ09 differences):
1.
From the command line, type:
cd /kernel/drv
2.
Edit the "st.conf" file by adding the following before the first occurrence of
"name=":
# entry for TLZ9L tape drive
tape-config-list = "DEC^^^^^TLZ9",
" DEC 8GB 4mm Helical Scan", "TLZ9-data";
TLZ9-data = 1,0x34,0,0x1639,4,0xfd,0xfd,0xfe,0xfe,3;
Where:
In the "tape-config-list" parameter:
•
The first parameter (
DEC^^^^^TLZ9
) is the parameter returned by the
tape drive on a SCSI inquiry command. (There should be five spaces
between the "DEC" and "TLZ9" elements.)
•
The second parameter (
DEC 8GB 4mm Helical Scan
) is a nickname for the
tape drive.
•
The third parameter is defined as follows:
In the
"TLZ9-data"
string:
–
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
=
0x0001
ST_BSF
=
0x0008
ST_BSR
=
0x0010
ST_LONG_ERASE
=
0x0020
ST_KNOWS_EOD
=
0x0200
ST_UNLOADABLE
=
0x0400
ST_LONG TIMEOUTS
=
0x1000
