Richard,
You could test it by IPLing a standalone utility on a DR tape drive from
your production center. Try it in a virtual machine first. If that
works, hopefully you have a test LPAR that you can try it on.

The 3270 will be at the end of a different 1000 mile wire.
The move to the DR site will be as you describe. The assumption is that
we are moving there because our normal center has been destroyed (used
as a set for an episode of 24, perhaps). The move to the DR site will
have local tapes and 3270s on a 3000 mile wire. After f few months, when
the normal center as been reconstructed, it will have brand new
everything. One way to accomplish the move might be to do a reverse DR
using tapes that are located at the normal DR site. Might is a key word
here. If the stand-alone utilities can be IPLed from there, there would
be no physical transport of tapes, something that our powers-that-be are
rightfully paranoid about.
Alternatively, we could find some way of creating any needed S-A
utilities at the new center.
Regards,
Richard Schuh

I don't know for sure. I can tell you in our old building (back
in the Sterling era) we had remote tape drives in Reston going to our
datacenter in Sterling (probably about 15 miles) and I personally did
this with that configuration.
That being said, admittedly for 99% of customers doing remote DR
exercises it's the "3270" that is at the end of the 2000 mile wire, not
the tape drive ... the tape drive is local (channel attached) to the
CPU.

Do any of the customers who have done/do this done it over a
2000 mile wire?

I know customers have done/do this.
Alternatively, you can place the HiDRO MODULE on your
PARM disk and IPL it stand-alone in the LPAR via the HMC (but you would
obviously have to have a PARM disk restored to do that ... implying you
would need to restore at least one volume via stand-alone tape IPL).

Has anyone ever ipled a stand-alone program, Hidro in
particular, from a remote tape drive? Is it even possible?
