Thanks Larry - this is exactly what I was looking for.

You've got the pieces but some thoughts.

1) The image catalog object in QUSRSYS is redundant really in this setup.
The images as you know are in the IFS and the QIMGCLG file contains what's
in the image catalog. So if you have the entire directory and then do
CRTIMGCLG with IMPORT(*YES) the QUSRSYS object will be created instantly
and in it's entirety.

2) The virtual optical device (e.g. OPTVRT01) can't be saved and restored.
OK it restores, but the virtual device that supports it won't be there and
it won't vary on. So you need to use CRTDEVOPT on the HA system to create
it there.

So mostly that leaves you the images themselves. So depending on the
technology the replication software uses you need to assure that those
objects are replicated. Clearly these are the big bulk of the bytes anyway.

We use image catalogs in library mode (this is not ptfs or OS stuff, but
real images stored on disk) and virtual image devices for our
applications.
Now looking a cloud based HA (high availability) solution and they are
asking questions about the objects related to this.
Is anyone else doing HA and virtual images - need to verify I have all the
related components:
