RE: Migrating extant system to new hardware

Externally sure, a SAS card could be added.

By far and away the easiest thing to do.

Larry, me, and a couple others keep cards/tape devices on hand so we can
make these types of migrations work.

Call for help?

Looks like he may need a tape migration service then.
One bad thing about not migrating to newer media during the life of your
system...

Hey, what is the new tape device on the P8? Will it work on the P6?

Given the systems are far apart, I would only do a SAVSYS to optical, then
the balance to tape.

In the end it's not going to really assist any so I'd just stay with tape
all the way.

Network boot while possible over a WAN is not going to be responsive
enough
to be reasonable.

If you are using VIOS don't use a tape image, use a DVD image so the
virtual
optical will work.

If you have the disk space on your P6 to store the entire system
again, but in an image catalog, that might be the way to go.


We do have enough space.

So then it's

1. SAVSYS to virt tape the extant system
2. Transfer the image somehow to new data center VIOS
3. Boot raw LPAR off that image

that a try first.

You might have to use your DVD as "an alternate IPL device" to get
into DST.

Most of the steps I have on how to configure it deal with creating the
virtual ethernet across the backplane. Might be easier if you're not
doing that. (Not near as fast or secure though.)

Rob: "no compatible tape drive" indeed. Target is one HMC-controlled
LPAR on P8.
Rob: If we go your 7.1->7.3 route, do we just 7.3 and then do a SAVSYS
and a restore or do we to a SAVSECDTA and something like SAVSTG or a
buncha SAVLIBs?

Jim: Very cool. Target has modern HMC with latest. Does Opt 40 on
LICPGM back up the whole system?

Normally I do NFS within the same system.
Now that I think about it I think you did mention it could be done
across systems.
I can grasp that for Upgrades and PTF's but new system installs also?
From
a single lpar system to a single lpar system? How would you
configure
the
NFS on the target?
Oh, now I remember; the only system which requires a line
description is the "hosting" system, the from system. All the
Guesting is done via SST
or
DST.
Wouldn't this require an HMC though to setup all the vswitch and
stuff?

I think you want a network install.

See:
ftp://ftp.software.ibm.com/systems/support/power/i/nfs_
optical_upgrade.pdf

What Larry and I do is an option 40 from the LICPGM menu to a
virtual optical device. You can make the optical disk big enough to
hold the whole thing or normal DVD sizes, doesn't matter. Then use
that as the load source. It'll bring over your LIC PGMs exactly
like they are on the P6.

Make sure to apply all of the needed PTFs before doing the option 40.

This is fast, reasonably easy and if you have a later version of the
HMC code (8.8.6 I think) you can do the network installation from
the HMC
GUI.
Very cool.

It's 7.1 -> 7.1
It's from a P6 to a P8.
I'd *like *to SAVSYS to a virtual tape image, make that image the
primary load source, and install the new raw partition from the
virtual
image.
I'm not quite sure yet as I root through the docs if that is doable,
because it seems the docs say that the target of the SAVSYS must
itself be a primary load source.

My "favorite"? Never let the hardware get so old that it can't

Then we upgrade and test a sandbox lpar.
Then upgrade other lpars (other than production, development and
their respective HA lpars).
Then we upgrade the "target" of our HA software.
And always upgrade the "source" before your next switch.

You don't want your source to be higher than your target. You
don't want to run into objects which can't be saved to the previous
release.

Favorite solution paths for migrating extant system to new hardware?

- Replication suites/hardware?
- Installing OS on new LPAR and restoring a SAVSYS?
- Booting/installing from SAVSYS on tape or virtual image?
