RE: Guest Partitions -- MIDRANGE-L

Hadn't thought about the implications of a Save 21, Jack. So, if I
understand correctly, one can do a Save 21 from either partition, but, if
done from the host, restoring the system restores the client. However, if
done from the client, only the client would be restored?

I am confused about the "take down the client and host" statement. Would it
actually be possible to take down the host? In my mind's eye I see the host
as being the top layer and immutable.

DRFranken: If you have this scenario which is best for the full system
save. Take down the client and host and do the 21 from there or do the 21
save directly on the client partition. I recently had to rebuild a box from
a 21 save tape and once the storage spaces got restored and I rebooted I was
all set, at least from the time I last did my full host side save.

I am sure others will chime in. HMC to setup the partitions. I have a
host with several guest partitions. The tape drive is shared between
partitions, the dvd is shared between all as well. Disk drives are owned

the hosting partition, one of the drawbacks is adding disk space via the
image catalog command so I would try and make sure you know for the most
part how much disk storage you would want on the host and clients. The
guest can IPL and have nill effect on the host, when the host is down so

are

the clients.

I have a BP coming in next week to give us a proposal for a Power 7

One of the questions that came up, when we were talking about our
needs/wants was partitioning so that, unlike today on our V5R1 machine,

could have a test environment separate from production.

This morning remembered some mention of a guest partition capability

when

6.1 was announced. I read some links that Rob provided but, admittedly,
I'm
still just a tad confused or unsatisfied. That is, the 6.1 technical
overview showed how to set up a client partition, but not how to use it

In a previous incarnation I had access to two [2] physical machines; one
for
production and one for development/testing. In 7.1 can/does this guest
(client) partition insulate the host partition (what would be in my case
Production) from updates made in the client? In the 2-box scenario I
ftped
libraries back and forth between the boxes; would that be the same
methodology for the client partition scenario? And when the client
partition is ended (the Redbook didn't go into whether this could be

done

or
how, but I figured it could be), do the libraries/objects in the client
just
disappear automagically?

Except for migrating objects between host and client, and using IBM i

and

disk space, I don't anticipate sharing resources. That is, such things
as
the tape drive, DVD drive, etc. But what the heck do I know. Anyway, I
just want to be able to set up a test environment that shields

production

from my tests.
