Compatibility

There are some differences from what a D3 user might expect in the way tape is handled on AIX, due to the way the AIX drivers work. This section lists these differences.

Quarter-inch tape compatibility

In the table below:

6157-001 is the 60 Megabyte IBM RT tape.
6157-002 is the 120 Megabyte IBM RT tape.
7207-001 is the multidensity RISC System/6000 tape.

Written by	Read by	3M Tape used	Compatibility
6157-001	7207-001	DC 300 XL/P	7207-001 will read tape
6157-001	7207-001	DC 600 A	Results are unpredictable
6157-001	7207-001	DC 6150	Results are unpredictable
6157-002	7207-001	DC 300 XL/P	6157-002 cannot write
6157-002	7207-001	DC 600 A	7207-001 will read tape
6157-002	7207-001	DC 6150	7207-001 will read tape
7207-001	7207-001	DC 300 XL/P	6157-002 cannot read or write
7207-001	7207-001	DC 600 A	7207-001 will read and write
7207-001	7207-001	DC 6150	7207-001 will read and write

Note:

Not all possibilities are covered in this chart.
DC 6150 is the new name for the 3M DC 600 XTD.
DC 300 XL/P is designed for the 6157-002; the DC 600 A and DC 6150 are designed for the 6157-002; the DC 6150 is preferred for the 7207-001.
Generally, a high-density drive can read a low density tape, but cannot write to it.
