PowerHA implies IASP. Only the IASP can be switched from one system to another.
You still have SYSBASE disks on all systems in the PowerHA cluster. And you can still perform your maintenance operations (upgrade, PTFs,
hardware) after switching over.

The big question here is do all our 20+ 3rd party products support IASP?
I don't think all do.

Apparently you can use Power HA and share the disk between two boxes.
When one box fails it flops over to the second box.
