Hi, Jack:

I think the only difference between a "switchable" disk pool and one that is not switchable is physically where the DASD that it is created over resides -- it is in a switchable tower that can be connected to more than one machine? See the topic of Clustering in the InfoCenter. To some extent, an IASP that can be "varied off" and then connected to a different LPAR and "varied on" can be said to be "switchable."

I think Larry Bolhuis or Jim Oberholtzer may be able to speak to this better than I can, as I think it is more of a "hardware" consideration, versus a software issue.

How much do the IASP rules change whether the setup is for non-switchable
and or switchable.

The IFS can only exist in an IASP by virtue of UDFS. Without UDFS,
there is no IFS in an IASP.

Perhaps you are unaware that a "default" UDFS (named "QDEFAULT.UDFS") is
created for you in each IASP automatically, so that "IBM i" can mount
that to provide the "root" directory for the IASP that you referred to
.... =-O
