RE: two headered tape

["Reeve Fritchman" <reeve@xxxxxxxxxx>]

You'll get HDR1 and HDR2; those have record length, block length, file name
information, etc.; these blocks (as well as EOF1 and EOF2) are created by
[OS/400] tape management.  Use *BLP ("bypass label processing") to skip
checking this stuff if you're getting labeled tapes unless you know the file
name, etc. and like the security of having tape management confirm the right
tape is loaded.

Otherwise, make sure the tape wasn't created with some funky backup utility;
you might be looking at application control information.

Subject: two headered tape

We still get a lot of stuff on tape.  The guy who sits next to me came up to
me this morning and asked "How many headers does a tape usually have?"  Then
he showed me the DMPTAP report on the first block and the header.  The tape
he was working with seems to have two headers, neither of which describe the
first block.  We're going to get another one--it's not critical that we get
the information off this particular tape. My question is "How did it get
that way?"
