RE: Recovery in an unmanned location -- MIDRANGE-L

Agreed a VTL is the "tape" solution of choice, all of them will do a bare
metal recovery. The thing is if they are willing to pop for a VTL why not
just get a contract with a hot site DR facility and eliminate all the other
stuff.

I understand the premise of the original post. I just see it as unreliable
and a problem filled DR solution.

With a VTL you never have to worry about physically handling the tapes.
That's what I use in all the unmanned data centers I use.
Yes I've done bare metal restores from them.

With ASMI access you can handle the power on and off. LAN Console, as
bothersome as it is, can handle the console aspects. But nothing will
replace a tape library where you can re-insert the tape, that, I would
think, is the showstopper...

All true Rob.

Additionally, How will you power it on? A single partition machine will
drop with an error code if there is no OS (at least LIC) , there is no
standby like there would be with an HMC.

Could it be done, maybe with smart PDUs etc. the better question is why?
A used HMC is only several hundred and might actually make it doable.

Tape would have to be loaded in the drive, or a tape library available
(TS3100 library is about $500 on the open market, plus tape unit).
Who/when is going to swap tapes? Cloud recovery? Sure give me a month

move the data.

The parameters are not realistic. You have to have a way to control

power,

mount tapes, and have a console.

LAN Console would help in that case. It would help if your local PC was

console as if it were ok that your data was open to the world but heaven
help you if your console access is. If not, then you'd need something
which could take control of some remote PC at that site which was the

LAN

Console.

I would check your end of tape options
SAVSYS DEV(MYTAPE) ENDOPT(*REWIND)
Or were abbreviating GO SAVE, option 21 as SAVSYS (which is a very bad
habit)? If so, then maybe there's some way to change the defaults on

that

too. However I cannot recall the last time I used that.

I would tend to avoid the DVD as that can get rather dated and would be
missing PTF's.

I have been given the hypothetical question of how could a single
partition Power 7 IBMi at V7R3 server with NO HMC and NO BRMS be

recovered

remotely ?

As USB is not supported on Power 7 as an alternate IPL device that is
ruled out.

If I put the I-BASE01 DVD in the DVD drive. I could initiate a D IPL

and

start a system install but I am not sure if I can get the system with

ONLY

the I-BASE01 to a operational level where I could then copy the

remaining

installation DVD images to a image catalogue or not ?

System does have internal LTO tape so I could do a SAVSYS to tape and
leave the tape in the drive. Only one problem is the SAVSYS will eject
the tape at then end and I don't know how to stop this ?

Please do not ask about how the issue occurred or how the failure of
hardware was resolved without manual intervention, as I said this is
hypothetical!!!

Any suggestions ?

Thank you

Don
