Byte 00, Bit 6 - EOP (End of Partition)
The EOP bit indicates whether the tape is positioned at the end of a
partition, as follows:
0 – The tape is not positioned at the end of a partition.
1 – For a dual-partition tape (8500c format only), the tape is
positioned between the logical end of partition (LEOP) and the
physical end of partition (PEOP) of the currently active partition.
For a single-partition tape or a tape written in 8500, 8200c, or 8200
format, the tape is positioned between LEOT and PEOT.
Byte 00, Bit 2 - BPU (Block Position Unknown)
The BPU bit indicates whether the block position is known, as follows:
0 – The block position is known and the remainder of the READ
POSITION data is valid.
1 – The block position is not known and cannot be obtained without
tape motion. The remainder of the READ POSITION data is not
valid.
Byte 01 - Partition Number
EXB-8505 When a dual-partition tape is loaded (8500c format only), the
Partition Number field returns the number of the partition in which
the tape is currently located, as follows:
0 – The current location is in the second partition on the tape.
1 – The current location is in the first partition on the tape.
If the loaded tape has no partitions, the value returned for this field
is 0.
EXB-8205 The EXB-8205 does not support multiple partitions. The value
returned for this field is 0.
