Transfer Length Satisfied

End of Tape (EOT) or End-
of-Partition (EOP)

Recoverable Data Error

Unrecoverable Data Error

LTO-2 SCSI Interface Guide
• If the Fixed bit is 1, it equals the difference between the CDB transfer
length and the number of actual blocks read.
• If the Fixed bit is 0, it equals the CDB transfer length.
On termination, the tape is positioned after the filemark on the EOT side
of tape.
If the CDB Transfer Length is satisfied, the command completes
2
successfully with a Good Status, and the tape is positioned on the EOT
side of the last block read.
When the end-of-tape or end-of-partition position is encountered, the
command terminates with a Check Condition and Medium Error (03h)
2
sense key. The Valid bit (byte 0, bit 7) and the EOM bit (byte 2, bit 6) are
set.
The Residual Length field is then set as follows:
• If the Fixed bit is 1, it equals the difference between the CDB transfer
length and the number of actual blocks read.
• If the Fixed bit is 0, it equals the CDB transfer length.
The logical position after encountering an end-of-tape or end-of-partition
error is undetermined.
If an error is encountered while reading the drive applies its retry
2
algorithm. If the algorithm process cannot recover the error is reported as
an unrecoverable read error.
If an Unrecoverable Data Error is encountered, the
2
terminates with Check Condition and a Medium Error (03h) sense key.
If the Valid bit (byte 0, bit 7) is set, Residual Length field equals the
difference between the requested Transfer Length and the actual number
of blocks or bytes transferred. On termination, the tape is positioned after
the error block on the EOT side of tape.
