Hi Rick,
Short answer: Due to the fact of Single Level Storage, many objects will reside in memory. Journaling is the way of forcing them to disc where PowerHA can replicate them.

Subject: Power HA and Journaling.
Hi Midrange Group,
This comes down again to not being able to find PowerHA for the system I classes to get the full grasp of the profuct.
I found out yesterday that another jurisdiction that has almost the same configuration we have, had to switch to their back up Iseries only to find when they switched back to the source system they had a large number of
damaged objects due to the objects not being journaled. From what I am
hearing, they assumed like us that in a cluster env. using geo mirroring that the need for journals on most objects in the data library were not needed like they would be in a environment such as Mimix that replicates on the object level.
So, can someone help me understand this a bit better because now I am being told we are going to have to start journaling most objects in our data library and this will cause me to lose a lot more disk space.
Not sure if what I am saying is clear or not....please let me know if you need more information to properly address the question.
Thanks all...................
