Re: Scratch Install V7R4 Client Partition from Image Catalog on Host

There is another option. Set up a repository on the HMC, with the I_BASE
dvd in that and create the partition using that dialog. Since the host is
V7R2 I'm guessing that it might be an older HMC, which is a bit more of a
task to perform but still possible.

Assuming the networking to be ok, verify when the image catalog was created
that the "Sort Image Catalog" was set to *YES as well as the "Network File
Server Share" is set to *YES.
Verify the export on the NFS files are correct and the permissions are
correct (in the document)
Verify the TFTP server is started. (try it from different place....)

I got a little further, but still no IPL. I followed the redpaper
instructions and double checked everything. The setup is using
virtual Optical Images of V7R4.

The Host is running V7R2. Prior to losing the Client LPAR, the
CLient LPAR was running V7R3. We want to bump the client up to V7R4.

I can see the TFTP activity on the host LPAR, but after C500E200 is
shown for a minute or two, the IPL fails with B600CF00

If it is not the case and if possible, set both client and host IPs in
the same subnet, at least without a firewall in the middle. tftp and nfs
rules are quite complex to set in such an environment.
If possible, you can try to configure a remote image catalog on a third
LPAR and check that you read the content of the first virtual CD which
must contain an I_BASE image, with WRKIMGCLGE IMGCLG(*DEV)
DEV(YOUR_REMOTE_VIRTUAL_OPTICAL_DEVICE) command.
There are also possible PTFs not installed on the 7.2 host or not
available on your I_BASE image. Make sure to use the very last available
RESAVE for 7.4.

In the past, a long time ago, I also faced a similar issue with physical
tapes, when I wanted to IPL D from a tape which did not provide the same
microcode version as the one which was installed on the disks. But it
was with old versions such as V4 or first V5. And I do not remember
exactly what was the failing IPL SRC code. The fact was that I could
repeat the issue and solve it with another tape with the same version as
the disks.

After recovering a server, we lost the image of our Test Client
Partition. Short answer on why, it was a playground and SOMEONE
(looking in mirror) forgot to make sure it was backed up.

I'm trying to perform a scratch install of V7R4.

The notes/instructions I have say I need to stick I-BASE into the
physical DVD drive to load LIC, etc.

Since I'm 70 miles away from the server, is there a way to boot from
an image catalog on the host?

You may want to checkout this redpaper
https://www.redbooks.ibm.com/redpapers/pdfs/redp4937.pdf

There is a chapter wich describes the steps for "Installing a new
system from the network"

It is a quite old redpaper so HMC screenshots are not really
up-to-date but you can review it and try. It talks about the HMC
command line to activate the LPAR but with modern versions you can use
the graphic interface.

I"m using an HMC for the config.
