I would be shocked, *shocked*, to find out that the application technically requires RAID-1. More likely, the vendor has specified that they "recommend RAID-1", and the admin has taken it as gospel. The specification for RAID-1 is typically a performance-driven one, based on negative feelings towards RAID-5, and not aware of the NetApp as a RAID-4 option. Worst comes to worst, you could use the AIX LVM, I believe, to make a RAID-1 mirror on top of two NetApp luns, and just waste the disk space.
Thanks, Matt

We are running an application called QAD that runs one of our manufacturing plants. According to our pSeries administrator it can only run on RAID1, does anyone have information about this? I am dubious but want to be certain.
It's on a pSeries that would be FC connected to the filer.
