Filemark, End of Medium (EOM), and Incorrect Length Indicator (ILI) Bits
Filemark (byte 2, bit 7), EOM (byte 2, bit 6), and ILI (byte 2, bit 5) are names
of fields in the SCSI-2 REQUEST SENSE command. Any of these bits may be set
to a 1 even though the Additional Sense Code (ASC) / Additional Sense Code
Qualifier (ASCQ) bits have a value of 0.
For example:
? Filemark, EOM, ILI bit may be set to 1 with No Sense key (00h) and ASC /
ASCQ = 00 00.
? Filemark, EOM, ILI bit may be set to 1 with Recovered Error (01h) and ASC
/ ASCQ = 00 00.
Filemark, BOM, ILI bit may be set to 1 with Medium Error (03h) and ASC /
ASCQ = 00 00.
