Yes, it is bunch of bits recorded on tape. And it seems there is no need
to support "mainframe CCW language", because it is VTS who writes on
(real) tape, not z/OS or any mainframe OS using VTS.
However the above is true now and it was true 5, 10, 15 or 20 years ago.
But VTS always had been using "mainframe-like" drives like Magstar or
Jaguar. More: even TS1155 was not supported by VTS.
I have never saw announcement or documentation claiming VTS supports LTO.
I suspect the reason of misunderstanding could be that VTS can be
attached to TS4500 or TS3500 or 3494 library. Each library support both
VTS-attached drives and distributed systems-attached drives which can be
TS11xx or LTO. Additionally TS3500 and 3494 could support native
mainframe drives as well, but only "mainframe family" (read: TS11xx or
older 3590s).
To simplify: VTS can be attached to TSx500 which is tape library. The
library, can be shared, it could support VTS and distributed systems.

It is what I understood from announcement, once tape drives will not connect
directly to z/OS channel but to VTS for destage.
VTS emulates 3490/3590 and can destage to any kind of tape, it is just a bunch
of bits to be recorded in tape.

Assunto: Re: RES: TS1140 tape transports
Does it mean one can replace his TS1140 drives with LTO?
I don't think so.
Correction: I don't think it is possible for z/OS or VTS clients. Note:
Windows/Unix host could use TS1140 natively.
