Just like when you restore a LIND to a new system you have to find the resource (WRKHDWRSC *CMN), and change the LIND to use the resource. You would do the same thing with the NWSD, you would find the 290B resource using WRKHDWRSC *CMN, and change the NWSD to use that. I have had to relink the storage spaces as well, but that is easy.

So let's get back to the question I have. Can you restore a guested lpar simply by restoring it's hosting lpar when restoring to a different machine? Or do things like SRM become a show stopper? I realize I may, strike that, will, have to apply new keys and may have to monkey around with resource names before varying on some items.

See RSTCFG "System Resource Management (SRM)"

No I was referring to a restore of a guest saved by an option 21 to a
standalone server.

Rather curious, I have some unload/reload's coming...

You would rebuild via the "Recover your server to a different system"
instructions I would think.

not matter on a guested lpar? Kind of handled by a traditional restore
when it asks you if you are restoring to a different system.

You make a couple of good points.

I actually have two distinct situations I am thinking about:
- A Hostingg partition that has no purpose other than to host some
guest partitions
- A production host partition hosting a dev partition

I've also been considering whether to factor in the possibility that
I might in the case of a disaster want to restore my guest to a
different system entirely. I think this is unlikely but at this stage
I am keeping it in mind. Most likely I will write the DR plan to
exclude such a possibility.

Restoring the storage spaces in their entirety means some time is lost
restoring libraries I know that I will overwrite. Of course their is a
considerable saving in time and complexity of the recovery process so
this may well be worth it.

Currently we have the time, and our guest partitions are not all that

and the host. Interesting idea though. I might mull that over.

In the case of catastrophe I would think recovering the guested system
as
a storage space would negate the need to to a restore of the guest.
And,
would be faster, and more inclusive. Why more inclusive? Well, your
BRMS
information, last save date (as updated by the full system save of the
guest), /tmp type stuff used by save/restore, etc would be included.
The
only additional stuff would be any guest saves done between the full
system save of the host and the damage to the object(s) you are trying
to
restore.
And a simple RST of the guested space on the host is MUCH easier than
the
step-by-step recovery from the full system save of the guest.

A save of the guest does allow for granularity of restore. For
example,
restoring one library to make a test library.

What is the rule of thumb of backup planning? Plan for how you'd
complete
your restore. The fastest COMPLETE restore of a guested lpar is by a
RST
of the storage space. (unless your host is also hosted, and backed
up,
by
VIOS [of which I don't know scat]).

Hi All

I have been considering the various options for backing up guest
partitions and wondered what other people do.

In my case I am considering backing up the individual hosted
partitions using a quarterly option 21 and a backup strategy tailored
to the use of each guest. I further plan to back up the host
periodically, or as the host changes to capture the full system
configuration. My current thinking is to have a full outage every 6
months. On one backup I will back up up everything, guest storage
(/QPFNWSSTG) included. On the other backup I am thinking of simply
backing up the host and the server descriptions but excluding the
/QPFNWSSTG directory to save time; I am still thinking this through. I
am trying to get to a situation where I can recover a system either
with the hosts intact, or with the hosts to be recovered separately or
not at all.

In the instance where I backup up the guests with individual backup
regimes I am trying to get a balance between preserving the guest
configuration on the host but at the same time avoiding having to save
and restore the network storage spaces when I will (potentially) be
overwriting the bulk of the storage during the guest recovery process.

While considering this I also wondered if while doing a full system
save the guest would remain operational if I took the option not to
end all servers. I'm not in a position to easily test this so I
wondered if they could remain operational. I'm starting to to think
this might be OK.

So what do others do ? What strategies do you have for backing up
hosting and hosted and hosted partitions ? What recover plans are your
backup strategies supporting ?
