Back in the earlier days of LPAR design it was easier to work with what is/was called buss level design then at levels of shared resources. As V5Rx rolled a long use of shared resources and IOAs without IOPs became common place to shared design for OPT & tape etal. Considerations on shared or exclusive has become more of a business decision as design, management and implementation improved.

Interesting.

At my last job we had BPs configure an LPARed system for us and all
three insisted that it needed to have a dedicated optical drive for each
LPAR. Here, we already had an LPARed system when I started, and it has
an internal DVD-Rom and two stand-alones. Each dedicated to an LPAR and
I haven't touched any of them in nine months!

Not dedicated but available. That is one optical drive for the physical
system is required and it can be switched between LPARs as needed. This
rule has not changed.

LPAR Optical requirement






I know that in the past a dedicated optical drive was required for each
LPAR; is this still the case? It seems odd to me that this requirement
is kept for hardware that could potentially only be used once in the
lifetime of a system.
