It's set in scsi_all.c:
/* DTL WRSOM */{SST(0x3A, 0x00, SS_NEDEF|ENXIO,
"Medium not present") },
/* DT WR OM */{SST(0x3A, 0x01, SS_NEDEF|ENXIO,
"Medium not present - tray closed") },
/* DT WR OM */{SST(0x3A, 0x02, SS_NEDEF|ENXIO,
"Medium not present - tray open") },
What would you suggest as an alternative? I'm certainly open to
suggestions. ENXIO gets returned for basically any type of medium not
present error.
If you want something just for tape drives, we can easily stick a
tape-drive-only error code in the sense code quirk table.
