I recently tried using my TEAC MT-2ST tapedrives
with FBSD2.2.5 and it messed up. I hacked around
a bit and made these changes:
To scsi/scsiconf.h, I added three lines
after the line containing "#define QIC_3080 0x29"
#define TEAC_8 0x08 /* mt2st */
#define TEAC_88 0x88 /* mt2st */
#define TEAC_A8 0xA8 /* mt2st */
To scsi/scsiconf.c, I added these seven lines
before the line containing "static st_modes mode_unktape ="
static st_modes mode_teac =
{
{512, ST_Q_FORCE_FIXED_MODE, 0}, /* minor 0,1,2,3 */
{512, ST_Q_FORCE_FIXED_MODE, TEAC_8}, /* minor 4,5,6,7 */
{512, ST_Q_FORCE_FIXED_MODE, TEAC_88}, /* minor 8,9,10,11 */
{512, ST_Q_FORCE_FIXED_MODE, TEAC_A8} /* minor 12,13,14,15 */
};
and then later in scsi/scsiconf.c, these additional eight lines to the
knowndevs array, at the end of the "#if NST > 0 ... #endif /* NST */" block
{
T_SEQUENTIAL, T_SEQUENTIAL, T_REMOV, "TEAC", "MT-2ST/N*", "*",
"st", SC_ONE_LU, ST_Q_FORCE_FIXED_MODE|ST_Q_NO_1024|ST_Q_IGNORE_LOADS, mode_teac
},
{
T_SEQUENTIAL, T_SEQUENTIAL, T_REMOV, "TEAC", "MT-2ST/F*", "*",
"st", SC_ONE_LU, ST_Q_FORCE_FIXED_MODE|ST_Q_NO_1024, mode_teac
},
After light testing, these appear to work. I'm sending these changes
to the list because I want to document them for the archives (so someone
else can use them); however, it would be even better if whoever maintains
the scsi code added them to the source tree.
