I agree! Not having to be on-site flipping DVDs is worth using image
catalogs alone. It's just a "set it & forget it" proposition imo. I
wrote a command to retrieve PTFs from IBM and another to load the images
to my virtual optical drive. Order PTFs, etc and once I get the
confirmation email with the relevant info (remote directory, etc) submit a
job using my command and it downloads the images, loads them to the image
catalog and all I have to do is mount the images to the virtual drive and
GO PTF. For upgrades it's basically the same procedure. Imo image
catalogs are the best thing to happen to applying PTFs, etc in MANY years!
Thanks,

All good points, but I will take a different angle in support of image
catalogs.......
With image catalogs there is no need for any on-site support during the
upgrade so you can do the upgrade from wherever remote access is
available. (Home office)
I hate working in the DC with all the noise, no place to actually sit, and
potential risk of bumping something just being in there. Not to mention,
typically large companies restrict DC access is so much that you must go
through all kinds of bureaucratic cycles just to go in and swap some DVDs
for an OS upgrade.....image catalogs are a no-brainer for me!

"It Depends" (as usual!)
If you have sufficient Arms (NOT GB!) then Image catalogs will be very
much faster plus you don't have to feed disks to the machine.
If you have few arms, physical media will win because the reading and the
writing is from/to the same overloaded arms.
So how many is "enough"? I generally say 8 Arms is good to go with Image
catalog. 4 arms is not enough. In between there it could go either way.

Jack, I used image catalogs in our recent upgrade to V7R1 from V5R4M5.
From your question I assume you are aware of these tasks to perform:
- Download and run the IBM Pre-upgrade Verification tool for i5/OS
