Coming soon will be the ability to IPL _and_ install directly from the HMC DVD
drive. It'll be a slow as !@$$ but it won't require an installation server
somewhere. You'll still need to connect _into_ the system over the network to
complete the install (via SSH or VNC) of course. Even that could be avoided if
you set up a custom DVD that points to an autoinst.xml file on the DVD itself
and use VNC as the installation method. Completely unattended install without
a net. :)
Actually, the capability to IPL from the HMC has been there for quite
some time. The capability to restore from DVD has been there not so
long, but still for quite a while (since z/OS V1.13 GA in 2011, if I
recall correcly). However, that installation process via standalone
restore is in place only for the Customized Offerings Driver (COD)
system, and not for a regular z/OS ServerPac installation.
The HMC DVD-based installation for the COD was *much* faster than we
thought it would be. We'd projected something like 8 hours, and it wound
up taking something closer to two. (We...well, I...forgot to account
for the effects of compression on the data rate, and system software
libraries are very compressible on the average. Blush.)
Of course, once the COD installation is done, you have z/OS running and
available to install a "real copy" of z/OS in the usual ways. One of
those ways is from DVD, but requires using a workstation as an FTP
source; using the HMC's DVD drive for this is not supported unless using
the HMC as an FTP source is supported, which I don't know.
Finally, if you want to put dump files of your own on DVD and restore
from them using the HMC's DVD drive, I suggest you put in a requirement
using RFE.
