Is PowerHA the same as V7R1 5770SS1 41 HA Switchable Resources?
I actually have it installed, along with Lic Key feature 5116
Are there any other LPP required?
Is part of base i5/OS, or is it an extra chargeable feature?
So, if I had enough resources, I could create an HA LPAR, correct?
Could this be a guest LPAR, or not recommended.
I would like to read up Power HA, any good books and/or links.

I would consider the HA LPAR to minimize the downtime during SYS SAVES and/or IPL for PTF apply.

I have several customers running PowerHA on IBM i. I know Jim O has the same. We also think there should be more classes and tried to get IBM to let us take their classes but they wanted us (as sellers, installers and supporters no less) to pay full price + T&E. Instead we taught ourselves.

The product is VERY different from the software guys (Mimix etc) though I'm not going to say Better or Worse because it depends on your environment.

One of the best points about is that once it is set up you do *NOTHING* to get objects to replicate. Zip, Zero, Nadda. You create a new file, it's replicated. Data area? Got that, whatever is in the library, replicated.

Another benefit is no journal receivers to mess with. Spent three hours on the phone yesterday with a customer who's HA partition went down because it ran out of disk space due to Mimix Journal receiver management getting 'unhooked'. REMEMBER: You still DO want to journal with PowerHA. Remember the Journaling Rules: 1) ALWAYS JOURNAL. 2) If you don't want to journal see rule 1. But with PowerHA they are not used for replication so you can manage the receivers more easily.

PowerHA continues to get better as well. There are multiple ways to implement the thing and we have come up with a couple that IBM basically pointed at us and laughed about. Then some guys in Europe actually started doing it that way and suddenly 'It's Legit'!

Sometimes I think IBM doesn't take me seriously. :-)

Can anyone tell me if you are currently using IBM’s PowerHA product
and if there are classes being offered on the product?

The one company I have found that does offer the class has canceled it
twice for low participation……..which makes me now wonder about the
product itself.

Thank you
