Doesn't this mean that they are only discontinuing a particular type of
3490E? The way I read this, they are not discontinuing making this type

Hi David,
The Read Block ID command (x'22') is documented in IBM 3490E Hardware

The requirements are easy. We ship tapes to a hardware duplication service.
That
I believe (I can be wrong here), that DFSMShsm do it in the following
way: it writes data until end of volume, then it moves back a number
of blocks. The number is counted as percentage of the tape.
You can followe this way or simply use ABARS.
BTW: Do you really need to create the TAPES ?
Thanks Mark! I will look at this as a possible solution.

David,
For the older 3480/3490 with IDRC, it is much harder. With 3490/E, it is
much easier to determine by looking at the block-id. The logical block-ID
increases as the physical blocks of data are written out; and then decreases

I have an obvious question on the 3490E though.
You say there is a set of tracks going AND coming.
Since actual tape length isn't a specification,
just a minimum is, how would a hardware duplication
device handle a 3490E?
In theory it wouldn't be able to, would it?
