Hi Samuel
I too had problems with LTO-2 drive definitions. After protracted wrangling
between StorageTek, IBM and Sun, here's what I'm using in my /kernel/drv/st.conf
files:
tape-config-list =
"IBM ULTRIUM-TD1", "IBM Ultrium Gen 1 LTO-custom", "IBM-LTO1",
"IBM ULTRIUM-TD2", "IBM Ultrium Gen 2 LTO-custom", "IBM-LTO2";
IBM-LTO1 = 1, 0x3B, 0, 0x19639, 4, 0x40, 0x40, 0x40, 0x40, 3;
IBM-LTO2 = 1, 0x3B, 0, 0x19639, 4, 0x40, 0x40, 0x42, 0x42, 3;
And if anyone is interested, here's what it all means!
1 version number (1 or 2)
0x3B type (see /usr/include/sys/mtio.h)
0 preferred block size (0=variable)
0x19639 options (bit pattern, for details see
/usr/include/sys/scsi/targets/stdef.h)
0x19639 contains the flags marked (*), any gaps left as an exercise
for the student... :-)
0x000001 * ST_VARIABLE
0x000002 ST_QIC
0x000004 ST_REEL
0x000008 * ST_BSF
0x000010 * ST_BSR
0x000020 * ST_LONG_ERASE
0x000040 ST_AUTODEN_OVERRIDE
0x000080 ST_NOBUF
0x000200 * ST_KNOWS_EOD
0x000400 * ST_UNLOADABLE
0x000800 ST_SOFT_ERROR_REPORTING
0x001000 * ST_LONG_TIMEOUTS
0x008000 * ST_NO_RECSIZE_LIMIT
0x010000 * ST_MODE_SEL_COMP
0x020000 ST_NO_RESERVE_RELEASE
0x040000 ST_READ_IGNORE_ILI
0x080000 ST_READ_IGNORE_EOFS
0x100000 ST_SHORT_FILEMARKS
0x200000 ST_EJECT_TAPE_ON_CHANGER_FAILURE
0x400000 ST_RETRY_ON_RECOVERED_DEFERRED_ERROR
4 number of compression options
0x40 compression value 1
0x40 compression value 2
0x42 compression value 3
0x42 compression value 4
3 default compression option
Cheers
Mike
