I am a developer and don't know much about HA, but we run ITERA's HA here.
I bet you know:
your HA costs
number of times HA has been used to continue/resume prod
approx cost of development
approx time to recover a test/dev lpar without HA
With that, I think you can get pretty close to being able
to backup your "I just can't see" and replace it with
"The cost does not appear to be justified because"

Subject: HA of Development LPARs

We have 25 LPARs of which 8 are development/sys test. These are on a good size 740 (terabytes of DASD). We run HA (MIMIX) for our production LPARs.
My question is does anyone run a full HA environment for their development? With all of the redundant hardware, software costs, MIMIX licenses, bandwidth, and overhead of supporting more partitions I just can't see how it is justified. We are a manufacturing company.

Comments please.
