I am reading the manuals in order to start the "Power HA" replication
process in a small system (five disk, all local)
If I create a disk pool using CFGASPDEV, will I be able to replicate it in
another server) Both are v7.4
Or is there a special need to make it "switchable"?

You have to set a host-based replication named Geographic Mirroring. It can uses any kind of disk storage. All other IASP replication will be based on Disk storage solutions.

Checkout the last sets of PowerHA redbooks

Up to POWER6 you could create an IASP built with internal disks and make it switchable between two servers which were sharing the same HSL loop.
Checkout the first PowerHA redbook http://www.redbooks.ibm.com/redbooks/pdfs/sg247405.pdf chapter 4.2

I believe the big requirement is a switchable iASP has to be on external
storage.

You can create a non-switchable iASP on a single system...

I have seen references to "switchable independent disk pool" and
"independent disk pool" without the "switchable"
Are all iASP switchable? or is there some special way to make an iASP
switchable?

TIA
