Thank all you very much!!!
I did nothing already. I only readed the manuals and found myself thinking about those questions. I don't really know if we can ask for DVD installation. We are only going to test z/VM, this is my very first contact with it. We have two mainframes (basically the production one and the backup/development one) and we would like to install z/VM on the last one, but we can only read 3480s from the production one. So what I thought was copying the tapes to DASD in the production machine, on shared DASD. If I could do this, my problems would be gone.
I talked to my boss and I think we'll order DVD installation. But, just in case we finally use tapes, I'll try to understand if the third phase (the one that happens after load the first DDR) can be done only from DASD.
Thank you very much again!! I'll tell you the finish of the story!

Victor,
First: Welcome to z/VM!
You did not cite where you are in the installation documentation where it
discussed IPLing the tape twice, so I have to presume that it is early in
process. The first IPL will bring up a standalone IPLable ICKDSF program,
with which you can initialize and format new DASD. Or, you can format the
DASD from some other running z/VM or z/OS. When the IPL from the tape
finished loading ICKDSF into memory, the tape stops right there. Don't
rewind it or move it
The second IPL of the tape loads the standalone IPLable DDR program
(something like FDR on z/OS, but nowhere near as advanced). With this you
can restore the z/VM "Initial Installation System" - which is a z/VM
system that IBM built so that installation programs can be run. It it NOT
the system you will use for production.
Once the IIS is loaded, you IPL that and begin the actual restore of the
fully-maintained z/VM system from the 3390 System DDR tapes.
I strongly suggest that you use the two-sided "z/VM Summary for Automated
Installation and Service" as an overview, and actually perform the
installation following the much more detailed z/VM Guide for Installation
and Service.
If you would like, I can e-mail to you the PowerPoint format presentations
I deliver at SHARE: "z/VM Installation - What Are You Afraid Of?", and
"z/VM Installation - It's Installed, Now What?". The are current up to
z/VM 5.1.0 Speaking of SHARE, you might what to consider visiting
www.share.org and registering for the next conference (Seattle, March
5-10, 2006). You won't find a better place to learn about z/VM and at a
very reasonable price considering the value derived.
Another recommendation. Unless your hardware does not support it, you
might consider re-ordering z/VM to get z/VM 5.2.0 which begins shipping
tomorrow (Dec 16,2005). Why go through the effort to install a system one
step out of pace?

Just a stupid question
Hi all!
I'm new in z/VM, and I must try to install it. My question is:
I was reading documentation and you should use the same tape in 2 IPLs for
doing different things. How do they do that? Do they check for the res
volume to be initializated?
And the other (and most important question): Could I copy the tapes on
disk
and do IPL from these disks?
I have problems for reading 3480s in the machine where I'm trying to
install VM.
Thank you very much!!!!
